MG4 Problems: Common Faults, Reliability & Fixes

The MG4 has established itself as one of the most affordable and appealing electric hatchbacks on the market. With its distinctive styling, practical interior, competitive driving range, and enjoyable performance, it offers an attractive alternative to more expensive electric vehicles.

However, despite its advantages, the MG4 is not completely free from reliability concerns. Since its introduction in 2022, owners have reported various issues involving the infotainment system, charging equipment, driver assistance technology, electrical components, and build quality.

Some MG4 problems are relatively minor and can be corrected through software updates or simple adjustments. Others may require professional diagnosis, replacement components, or more extensive repairs.

If we're considering buying a new or used MG4, understanding these potential weaknesses can help us make a better decision and avoid unexpected expenses.

In this comprehensive guide, we'll examine the most common MG4 problems, their symptoms, possible causes, and recommended solutions. We'll also explore the vehicle's reliability, battery performance, repair costs, and the most important things to inspect before purchasing one.

Most issues discussed relate to the original MG4 EV introduced in 2022. Updated and newly developed MG4 models may have different characteristics and should be evaluated individually.

Are MG4 Electric Cars Reliable?

The MG4 offers impressive value for money, but its reliability record has attracted criticism.

In the 2024 What Car? Reliability Survey, the MG4 received a reliability rating of approximately 63.8%, placing it near the bottom of the electric car category.

Around 30% of surveyed MG4 vehicles were reported to have experienced a fault. Some owners also faced lengthy repair times, making the ownership experience more frustrating.

The model performed better in the 2025 survey, although reliability concerns remained.

These results indicate that the MG4's main weaknesses are often associated with electronic systems, software, and certain interior components rather than widespread failures of its electric motor or main battery.

Nevertheless, we should remember that reliability surveys reflect the experiences of participating owners. They do not mean that every MG4 will develop serious problems.

MG4 Reliability Overview

The good news is that certain early complaints have been addressed through updates and service improvements.

However, we should still inspect any used MG4 carefully before making a purchase.

1. MG4 Infotainment System Problems

One of the most frequently reported MG4 problems involves the infotainment system.

The MG4 uses a central touchscreen to control entertainment, navigation, connectivity, climate settings, and several vehicle functions.

Although the system provides a modern appearance, some owners have experienced slow responses, unexpected restarts, and connectivity issues.

Common MG4 Infotainment Symptoms

Typical complaints include:

• Touchscreen freezing during operation.
• Delayed responses when selecting menus.
• Apple CarPlay disconnecting unexpectedly.
• Android Auto connection failures.
• Bluetooth connectivity problems.
• Reversing camera display delays.
• Navigation software behaving incorrectly.
• Vehicle settings occasionally resetting.

These issues can be particularly inconvenient because several important vehicle features depend on the touchscreen.

What Causes MG4 Screen Problems?

Software bugs are one possible explanation.

Modern infotainment systems contain numerous interconnected functions, and communication errors between software modules can affect performance.

Outdated firmware, smartphone compatibility problems, or defective electronic components may also contribute.

In some cases, the issue appears intermittently, making diagnosis more difficult.

How to Fix MG4 Infotainment Problems

We can begin by disconnecting our smartphone and checking whether the problem continues without Apple CarPlay or Android Auto.

If the infotainment system remains unresponsive, restarting it according to the manufacturer's instructions may temporarily restore functionality.

We should also contact an authorised MG dealership to check whether updated software is available.

Persistent freezing, repeated restarts, or a completely blank display may require professional diagnostics.

Before purchasing a used MG4, we recommend testing the touchscreen thoroughly, including navigation, audio, Bluetooth, climate controls, and smartphone integration.

2. MG4 Lane Keeping Assist Problems

The MG4's lane keeping assistance system has generated considerable discussion among owners.

This technology is designed to help prevent the vehicle from unintentionally leaving its lane.

However, some drivers of earlier MG4 models reported unexpectedly aggressive steering corrections.

Common Lane Assist Complaints

Owners have described problems such as:

• Sudden steering intervention.
• Excessive corrections near lane markings.
• Unexpected assistance on narrow roads.
• Steering resistance during normal driving.
• Repeated lane departure warnings.
• Uncomfortable behaviour on roads with unclear markings.

Although lane keeping systems are designed to improve safety, intrusive intervention can make the driving experience less predictable.

Has MG Fixed the Lane Assist Problem?

Following concerns raised about the system's behaviour, MG developed revised software intended to improve its operation.

Software updates were distributed through dealerships, particularly for earlier vehicles.

However, we should not assume that every used MG4 has received the relevant updates.

The software version installed in the individual vehicle matters.

How to Address Lane Keeping Problems

If our MG4 makes unexpected steering corrections, we should contact an authorised dealership and ask whether the latest applicable driver assistance software has been installed.

We should also describe the conditions under which the problem occurs.

For example, does it happen on narrow roads, during motorway driving, or when road markings are difficult to see?

If steering assistance behaves unpredictably or makes the car difficult to control, we should stop safely and arrange a professional inspection.

Safety-related issues should never be ignored.

3. MG4 Charging Problems

Charging difficulties are another concern reported by some MG4 owners.

The vehicle supports AC charging and DC rapid charging, although charging capabilities vary depending on the battery version and model.

While most charging sessions should work normally, some drivers experience connection failures, interrupted sessions, or unexpectedly low charging speeds.

MG4 Not Charging at Home

One common complaint involves connecting the vehicle to a home wallbox without charging successfully beginning.

Other owners report charging sessions stopping earlier than expected.

Possible explanations include:

• Charging schedule conflicts.
• Wallbox communication errors.
• Faulty charging cables.
• Incompatible charger settings.
• Charging connector problems.
• Software malfunctions.
• Faults in the onboard charging system.

Before assuming the vehicle itself is defective, we should check whether the same problem occurs at another compatible charging station.

If the car charges normally elsewhere, the original charger or its configuration may be responsible.

MG4 Rapid Charging Problems

Some drivers have reported difficulties starting DC rapid charging sessions.

However, charging performance depends on several factors.

Battery temperature, state of charge, charging station power, and battery management limitations can all influence the charging speed.

For example, a cold battery may charge significantly more slowly than a battery operating at a suitable temperature.

Similarly, charging speeds typically decrease as the battery approaches a high state of charge.

A slower charging session does not automatically indicate a defective battery.

How to Fix MG4 Charging Problems

We recommend checking the charging cable, vehicle settings, and charging station before arranging repairs.

If the MG4 repeatedly fails to charge at several suitable charging stations, a technician should inspect the vehicle.

Charging system faults may require diagnostic testing of the onboard charger, charging port, electronic control modules, or associated components.

We should never attempt to repair high-voltage charging equipment ourselves.

4. MG4 Charging Cable Stuck

Another reported issue involves the charging connector remaining locked after a charging session.

The MG4 uses an electronic locking mechanism intended to keep the connector secured while charging.

Occasionally, the connector may fail to release as expected.

Why Does the MG4 Charging Cable Get Stuck?

Possible reasons include a charging session that has not fully ended, a temporary communication error, a locking mechanism fault, or an electrical problem.

In some situations, the vehicle may still consider the charging session active.

How to Release the Charging Cable

First, we should confirm that charging has stopped.

Next, follow the normal unlocking procedure described in the vehicle's owner's manual.

Certain MG4 versions have an emergency cable release mechanism, but its location and operating procedure can vary.

We should consult the correct instructions before attempting to use it.

Never force the connector out of the charging port, as doing so could damage the locking mechanism or charging equipment.

If the cable remains stuck, professional assistance may be necessary.

5. MG4 12V Battery Problems

Although the MG4 is a fully electric vehicle, it still relies on a conventional 12-volt auxiliary battery.

This smaller battery supplies essential low-voltage electrical systems and helps activate the components required to make the vehicle operational.

Some owners have reported situations where their MG4 became unresponsive because of a discharged or failing 12V battery.

Symptoms of a Weak 12V Battery

Possible symptoms include:

• The vehicle failing to start its electronic systems.
• Remote locking becoming unresponsive.
• Multiple dashboard warnings appearing.
• Interior displays failing to activate.
• Electrical components operating intermittently.
• The vehicle refusing to enter its driving-ready state.

These symptoms can be confusing because the main high-voltage battery may still contain substantial charge.

What Causes MG4 12V Battery Problems?

Possible causes include normal battery deterioration, a defective auxiliary battery, an excessive electrical drain while parked, or faults affecting the low-voltage charging system.

Vehicles that remain unused for extended periods may also be more susceptible to auxiliary battery discharge.

How to Fix the Problem

A technician should test the 12V battery and the system responsible for maintaining its charge.

If the battery is defective, replacement may resolve the issue.

However, if the battery repeatedly loses charge, further investigation is necessary.

Installing a new battery without identifying an underlying electrical drain may only provide a temporary solution.

6. MG4 Dashboard Warning Lights

Unexpected dashboard messages are another source of frustration for some MG4 drivers.

Modern electric vehicles use numerous sensors and electronic control modules to monitor electrical, mechanical, and safety systems.

When the vehicle detects an abnormal condition, a warning message may appear.

Common MG4 Warning Issues

Reported problems include intermittent electrical warnings, driver assistance alerts, charging system notifications, and messages relating to vehicle control systems.

Sometimes these warnings disappear after restarting the vehicle.

However, a disappearing warning does not necessarily mean that the underlying fault has been corrected.

What Should We Do?

The appropriate response depends on the warning.

Minor notifications may require a routine check, while critical braking, battery, steering, or propulsion warnings require immediate attention.

If the vehicle displays a serious warning or instructs us to stop, we should follow the manufacturer's safety instructions.

For recurring warnings, a professional diagnostic scan can help identify stored fault codes.

It can also be useful to photograph the warning message and record the driving conditions when it appeared.

7. MG4 Reduction Gearbox Oil Leaks

Even though the MG4 does not have a conventional petrol engine, it still contains mechanical drivetrain components that require lubrication.

One of these components is the reduction gearbox, which transfers rotational power from the electric motor to the wheels.

Some early MG4 vehicles were associated with reports of lubricant escaping through the reduction gearbox breather system.

Symptoms of an MG4 Gearbox Oil Leak

Possible signs include:

• Oily residue near the drive unit.
• Visible fluid accumulation beneath the vehicle.
• Oil marks on underbody panels.
• Unusual drivetrain noises.
• Evidence of lubricant leakage during servicing.

Not every fluid stain beneath the car indicates a gearbox fault, so proper diagnosis is essential.

What Causes the Oil Leak?

Some early reports involved the gearbox breather arrangement.

The breather allows pressure equalisation within the gearbox, but oil may escape if the system does not manage lubricant movement effectively.

Revised breather components have been discussed as a corrective measure for certain early vehicles.

Is an MG4 Gearbox Leak Serious?

The severity depends on the cause and quantity of lubricant lost.

A small amount of residue is different from an active leak that reduces the gearbox's oil level.

Excessive lubricant loss can eventually affect internal components.

If we suspect a gearbox leak, we should arrange a professional inspection promptly.

How to Fix MG4 Gearbox Oil Leaks

Repairs may involve checking the breather system, inspecting seals, verifying lubricant levels, and fitting updated components where appropriate.

If we're buying an early MG4, it is worth asking whether the gearbox has previously been inspected or repaired.

8. MG4 Undertray Problems

Another issue reported on some earlier MG4 vehicles involves the underbody protective panels.

These panels help protect components beneath the vehicle and contribute to aerodynamic efficiency.

Some owners have noticed sections of the undertray sagging or appearing lower than expected.

Why Does the MG4 Undertray Sag?

Potential causes include panel distortion, fastening problems, installation defects, or damage caused by road obstacles.

A damaged or poorly secured undertray may produce rattling noises or reduce clearance beneath the vehicle.

How to Identify Undertray Damage

We should visually inspect the underside of the vehicle from a safe position.

Look for loose panels, damaged fasteners, unusual deformation, or components hanging below their intended position.

We should never crawl beneath a vehicle that is not properly supported.

Can the Undertray Be Repaired?

Depending on the problem, a workshop may be able to secure, adjust, repair, or replace the affected panel.

If the panel has been damaged by an impact, technicians should also inspect nearby components.

9. MG4 Suspension and Steering Problems

The MG4 has received positive feedback for its handling and overall driving dynamics.

Its dedicated electric vehicle platform provides a low centre of gravity and balanced road behaviour.

Nevertheless, some owners have reported suspension noises or unusual steering sensations.

MG4 Suspension Knocking

Knocking sounds may become noticeable when travelling over speed bumps, potholes, or uneven roads.

Possible causes include worn suspension joints, loose mounting components, damaged bushings, or other mechanical issues.

However, interior trim and loose objects can sometimes produce similar noises.

A technician should identify the source before replacing suspension components.

MG4 Steering Vibration

Steering vibration may be caused by wheel imbalance, damaged tyres, alignment problems, or suspension faults.

If vibrations appear after driving over a pothole, wheel and tyre condition should be checked.

Persistent vibration requires investigation, especially if it becomes more noticeable at higher speeds.

10. MG4 Interior Rattles and Build Quality

The MG4 offers an attractive interior for its price, but cabin material quality is not its strongest characteristic.

Some owners have reported rattles, squeaks, or poorly aligned trim components.

These complaints are generally less serious than mechanical or electrical faults, but they can affect everyday comfort.

Common Interior Complaints

Owners may notice noises coming from the dashboard, centre console, door panels, or luggage compartment.

Some vehicles also exhibit trim pieces that do not fit perfectly.

How to Fix Interior Rattles

A workshop may be able to adjust loose panels, replace defective clips, or apply suitable anti-rattle materials.

Intermittent noises can be difficult to reproduce, so recording the sound may help technicians locate the problem.

When test-driving a used MG4, we should listen carefully while travelling over uneven roads.

11. MG4 Heating and Air Conditioning Problems

Some MG4 owners have reported inconsistent heating or air conditioning performance.

Electric vehicle climate-control systems differ from conventional combustion-engine systems because they do not rely on waste heat from a petrol or diesel engine.

Depending on the MG4 version, cabin heating equipment and thermal management arrangements may vary.

Common Climate Control Symptoms

Potential problems include weak heating, air conditioning that stops working, inconsistent cabin temperatures, or unexpected noises while the system operates.

Possible causes range from software or sensor issues to faults involving electrical or refrigerant components.

Is Reduced Winter Range Normal?

Yes.

Using cabin heating increases electricity consumption, particularly in cold conditions.

This can reduce the distance the vehicle travels between charging sessions.

A decrease in winter range does not automatically indicate a defective heater or traction battery.

However, if the MG4 cannot maintain a reasonable cabin temperature, professional inspection is advisable.

12. MG4 Real-World Range Problems

The MG4 is available with different battery capacities and powertrain configurations.

As a result, official driving range figures vary between versions.

Some owners are disappointed when their real-world range falls below the published figure.

However, this difference is not necessarily evidence of a fault.

Why Is My MG4 Range Lower Than Expected?

Several factors influence energy consumption:

• Motorway driving at higher speeds.
• Cold weather.
• Strong headwinds.
• Steep roads.
• Cabin heating or air conditioning.
• Tyre pressure.
• Driving style.
• Additional vehicle weight.

Official range figures are measured under standardised conditions that may not represent everyday driving.

How to Improve MG4 Driving Range

We can improve efficiency by maintaining correct tyre pressures, using smooth acceleration, reducing unnecessary speed, and taking advantage of cabin preconditioning when available.

We should also remember that the dashboard's estimated range changes according to driving conditions.

A sudden, unexplained reduction in range under similar conditions may justify a battery health assessment.

13. MG4 iSMART App Problems

Depending on the model and market, the MG4 can provide connected services through the MG iSMART smartphone application.

The application allows compatible vehicles to communicate information and support certain remote functions.

However, some owners experience connectivity problems.

Common MG iSMART Issues

Reported symptoms include delayed vehicle status updates, failed remote commands, login difficulties, and unreliable communication between the application and the vehicle.

These problems can originate from the smartphone, internet connection, application software, or vehicle communication hardware.

How to Fix MG iSMART Problems

First, we should confirm that the application is updated.

Next, verify that the phone has a stable internet connection and that the vehicle is correctly linked to the account.

If the problem continues, an MG dealership may need to check the vehicle's communication module or software configuration.

An application problem does not necessarily indicate a fault in the high-voltage battery.

14. MG4 XPower Vibration Problems

The MG4 XPower is the high-performance version of the electric hatchback.

Its dual-motor all-wheel-drive system delivers significantly stronger acceleration than the regular MG4.

However, some owners have reported vibration problems at motorway speeds.

MG4 XPower High-Speed Vibration

Some drivers describe vibration or humming sensations at speeds around 60–75 mph, equivalent to approximately 97–121 km/h.

The sensation may be transmitted through the steering wheel, seats, or vehicle structure.

Not every MG4 XPower exhibits this behaviour, and its severity varies between reported cases.

What Causes MG4 XPower Vibration?

Possible causes of vehicle vibration include wheel imbalance, tyre irregularities, wheel alignment problems, or drivetrain-related issues.

However, we should not assume that all reported XPower vibrations share the same cause.

A complete inspection is necessary.

How to Check Before Buying

If we're considering purchasing an MG4 XPower, we recommend a thorough road test.

Where conditions and speed limits allow, assess the vehicle at normal motorway speeds.

We should also ask whether any previous vibration complaints have been investigated and obtain documentation of completed repairs.

15. MG4 Door Lock Recall

Certain early MG4 vehicles were affected by a safety recall involving the central locking system.

In the United Kingdom, recall R/2022/355 concerned vehicles produced during part of 2022.

The issue involved the possibility of the superlocking function activating while the vehicle was in running mode.

This could potentially prevent occupants from opening the doors normally.

How Was the Problem Addressed?

The manufacturer specified a software update to correct the issue.

Owners of affected vehicles were directed to authorised dealerships.

How to Check for MG4 Recalls

Before purchasing a used MG4, we should provide the vehicle identification number to an authorised MG dealership and request confirmation of outstanding recalls.

It is also important to verify that previously announced safety repairs have actually been completed.

A completed safety recall does not automatically mean every optional software update has been installed.

16. MG4 Tyre Wear and Brake Problems

Electric vehicles can place additional demands on tyres because of their weight and immediate torque delivery.

The MG4 is no exception, particularly in high-performance configurations.

Uneven MG4 Tyre Wear

Uneven tyre wear may result from incorrect alignment, unsuitable tyre pressure, suspension wear, or aggressive driving.

We should inspect both the inner and outer edges of the tyres.

If one side of the tread is wearing significantly faster than the other, an alignment and suspension inspection may be necessary.

MG4 Brake Disc Corrosion

The MG4 uses regenerative braking to recover energy during deceleration.

This means conventional friction brakes may receive less frequent use than those on many petrol vehicles.

Under certain conditions, especially in wet climates or with limited driving, brake discs may develop surface corrosion.

Minor rust after parking can be normal.

However, excessive corrosion, grinding noises, or reduced braking performance require professional attention.

17. MG4 High-Voltage Battery Problems

Battery reliability is one of the biggest concerns for anyone considering an electric vehicle.

The high-voltage battery is a major component, and replacing a complete pack outside warranty can be expensive.

Fortunately, not every electrical warning or charging problem indicates high-voltage battery failure.

Does the MG4 Have Battery Degradation Problems?

Like all lithium-ion batteries, the MG4 traction battery gradually loses some capacity as it ages.

The rate of degradation depends on battery chemistry, temperature, charging habits, mileage, and time.

However, available long-term evidence does not establish an unusually widespread MG4 traction battery degradation problem.

How to Check MG4 Battery Health

When buying a used MG4, we should request a battery state-of-health assessment where available.

This can help determine how much capacity remains compared with the battery's original usable capacity.

We should also check for diagnostic warnings, unusual charging behaviour, and unexplained reductions in driving range.

The dashboard's estimated range should not be treated as an accurate battery health percentage.

How Long Does an MG4 Battery Last?

There is no single lifespan that applies to every MG4.

Battery longevity depends on operating conditions, battery chemistry, maintenance, and usage.

Many electric vehicle batteries can remain functional for years, even after some capacity has been lost.

We should focus on measured battery condition rather than assuming that an older battery automatically needs replacement.

18. Which MG4 Model Years Have the Most Problems?

The MG4 was introduced in 2022, making the earliest vehicles especially relevant when researching recurring faults.

As with many newly introduced models, early production cars can experience software and manufacturing issues that are subsequently addressed.

However, there is insufficient comprehensive year-by-year reliability data to establish a definitive ranking of every MG4 model year.

MG4 2022–2023 Problems

When inspecting early-production MG4 vehicles, we should pay particular attention to:

• Outstanding safety recalls.
• Reduction gearbox breather leaks.
• Undertray condition.
• Driver assistance software.
• Infotainment stability.
• Charging performance.
• Electrical fault history.

Some problems associated with early production may have been corrected through dealership work.

MG4 2024–2025 Problems

Later examples may benefit from revised components and updated software.

However, charging issues, infotainment complaints, and electronic faults can still occur.

A newer model year does not guarantee complete reliability.

MG4 2026 Problems

Updated MG4 models introduced for the 2026 model range should be evaluated separately from earlier vehicles.

Changes in design, equipment, battery technology, or software may influence reliability.

Long-term ownership data will be necessary before drawing firm conclusions about these newer models.

19. MG4 Repair Costs

The cost of repairing MG4 faults varies depending on the affected component, labour rates, warranty coverage, and parts availability.

Some problems can be resolved through software updates, while others require replacement electronic modules or mechanical components.

MG4 Common Repairs

We should avoid relying on generic repair estimates for major electric vehicle components.

Actual prices can differ considerably between countries and workshops.

Does the MG4 Have a Good Warranty?

Eligible UK MG4 vehicles generally benefit from a seven-year manufacturer warranty, subject to the applicable mileage restrictions and terms.

However, warranty conditions can differ between markets and model years.

Before purchasing, we should confirm the exact coverage attached to the individual vehicle.

It is particularly important to understand the conditions applying to the traction battery, electronics, and previous repairs.

20. How to Prevent Common MG4 Problems

Although some faults are outside our control, good maintenance practices can help reduce the risk of avoidable issues.

Keep Vehicle Software Updated

Software plays an important role in the MG4's operation.

We should regularly ask an authorised dealership whether there are relevant updates for the vehicle's infotainment, driver assistance, or other electronic systems.

Follow the Recommended Service Schedule

The MG4 does not require conventional engine oil changes, but routine maintenance remains essential.

Servicing may include brake inspections, tyre checks, suspension examinations, fluid checks, electronic diagnostics, and other manufacturer-specified procedures.

The appropriate service interval depends on the market and vehicle version.

Inspect Tyres and Brakes

Correct tyre pressure improves safety, efficiency, and tyre life.

Regular brake inspections are also important, especially for vehicles driven mainly in urban traffic where regenerative braking may reduce friction brake use.

Monitor Charging Performance

We should become familiar with the vehicle's normal charging behaviour.

Repeated interruptions or charging failures should be investigated rather than ignored.

Maintain the Auxiliary Battery

If the MG4 is left unused for extended periods, we should follow the manufacturer's storage and battery maintenance recommendations.

A healthy 12V battery is essential for reliable electronic operation.

21. What to Check Before Buying a Used MG4

A used MG4 can represent excellent value, particularly as electric vehicles depreciate and more examples enter the second-hand market.

However, choosing the wrong vehicle could result in frustrating electrical problems or expensive repairs.

Used MG4 Inspection Checklist

Test Drive Recommendations

During the test drive, we should check acceleration, braking, steering behaviour, and suspension comfort.

It is also important to test the infotainment system and monitor the dashboard for warning messages.

If possible, confirm that the vehicle charges successfully and that the charging connector releases normally.

A specialist inspection can provide additional reassurance, especially when purchasing a higher-mileage example.

22. Is the MG4 Worth Buying Despite Its Problems?

The MG4 continues to offer several compelling advantages.

Its competitive pricing, responsive handling, practical interior, and electric driving capabilities make it attractive to drivers who want an affordable EV.

However, reliability is an important part of the ownership experience.

Software malfunctions, charging difficulties, and lengthy repair times can reduce the appeal of an otherwise enjoyable vehicle.

Reasons to Buy an MG4

The MG4 offers good value compared with many competing electric hatchbacks.

Its rear-wheel-drive layout on standard versions contributes to enjoyable handling, while its interior provides useful everyday practicality.

Depending on the specification, buyers can also benefit from a competitive driving range and generous equipment.

Reasons to Think Twice

We should be more cautious if the vehicle has a history of repeated electrical faults, unresolved charging issues, or persistent warning messages.

Limited access to authorised servicing or slow parts availability can also be important drawbacks.

An MG4 with documented maintenance and completed software updates may be a better purchase than a cheaper example with an uncertain repair history.

Ultimately, the car's individual condition is more important than simply choosing a particular registration year.
