MG HS Problems: Complete Guide to Common Issues, Causes, and Solutions

The MG HS stands as one of MG’s most popular compact SUVs, blending modern design, solid performance, and an appealing price point. Yet, despite its attractive styling and premium feel, many owners have reported recurring faults that impact the driving experience and reliability.

In this in-depth guide, we explore every MG HS problem in detail — from electrical and transmission issues to suspension, paint, and braking system faults — and provide practical advice to help owners diagnose, prevent, and fix them effectively.

Overview of MG HS Reliability

When MG reintroduced itself to global markets, the MG HS quickly became one of its flagship SUVs. It was celebrated for its five-star Euro NCAP safety rating, spacious cabin, and affordability. However, the 2022 Driver Power Survey revealed that 35% of MG owners reported a fault within the first year, placing the brand below average in reliability rankings.

That doesn’t make every MG HS problematic, but it does highlight the importance of being aware of recurring issues and addressing them proactively.

Electrical System Problems

Infotainment System Glitches

Many owners experience frozen or unresponsive touchscreens, Bluetooth connection drops, or malfunctioning USB ports. The 10.1-inch infotainment system, while feature-rich, has been prone to lag and random restarts.

Common causes:

• Faulty head unit software
• Outdated firmware
• Weak connection between the infotainment system and sensors

Recommended fix:

• Request a software update from an MG-authorized dealer.
• Perform a factory reset to clear cached data causing lags.

Battery and Starting Issues

Reports include non-starting engines, flickering dashboard lights, and faulty keyless entry systems.
These are often linked to low-voltage batteries or electrical relay faults.

Solution: Replace the 12V battery with an OEM-approved unit and have all fuses and relays checked by a qualified technician.

Transmission and Gearbox Issues

The 7-speed dual-clutch transmission (DCT) in the MG HS is smooth when new, but some owners report jerking, hesitation, or delayed gear shifts — particularly in stop-and-go traffic.

Symptoms:

• Delayed acceleration after pressing the throttle
• Slipping or clunking during gear changes
• Warning lights for “Transmission Fault”

Likely causes:

• Worn clutch pack
• Faulty mechatronic unit
• Low or degraded transmission fluid

Fix:
Regularly change the DCT transmission fluid every 40,000–50,000 km and ensure that all software updates are installed to recalibrate shift timing.

Suspension and Ride Comfort Concerns

While the MG HS delivers good handling, some drivers report a stiff and noisy ride. On uneven roads, the car can feel harsh, with clunking or knocking sounds emerging from the undercarriage.

Common causes:

• Worn bushings or control arms
• Damaged struts or shock absorbers
• Loose anti-roll bar links

Fix:
Have a full suspension inspection done and replace deteriorated components with OEM parts. Wheel alignment can also improve ride comfort significantly.

Paint and Exterior Quality Defects

Aesthetic issues may not affect drivability, but paint peeling, premature fading, or flaking are frequent complaints among MG HS owners.

Root causes:

• Inadequate paint curing during production
• Low-quality clear coat layers
• Poor protection from environmental exposure

Solution:
Report early signs of paint failure to MG within warranty. Regular ceramic coating or wax treatments can extend paint longevity and prevent oxidation.

Brake System Malfunctions

Drivers have reported squeaking or grinding noises, reduced braking performance, and pulsation in the brake pedal.

Probable causes:

• Worn brake pads or warped rotors
• Contaminated brake fluid
• Improper caliper alignment

Fix:

• Replace brake pads and resurface rotors if thickness variation is present.
• Flush brake fluid every 2 years.
• Inspect ABS sensors for corrosion or debris.

Quality Control and Fitment Issues

Some units show inconsistent build quality, including misaligned panels, rattling dashboards, and loose trim pieces.

Why it happens:
These imperfections often stem from assembly tolerances or insufficient quality inspections during manufacturing.

Fix:
An MG dealer can adjust panel alignments or re-secure interior trim under warranty. Owners should report these defects early to avoid further deterioration.

Electric Tailgate Malfunction

A frustrating fault for many owners is the electric tailgate failing to close or opening midway. This issue is often related to software calibration errors or weak actuators.

Fix:
Reprogramming the tailgate system can temporarily resolve it, but actuator replacement may be necessary for a permanent solution.

Sensor Sensitivity Problems

MG HS’s driver-assistance systems — such as adaptive cruise control and emergency braking — can misbehave in heavy rain, fog, or snow, triggering false alarms or erratic braking.

Causes:

• Radar or camera obstruction
• Overly sensitive calibration
• Moisture ingress in sensor modules

Tip:
Clean sensor areas frequently and have ADAS calibration checked during each service.

High Fuel Consumption

Despite the manufacturer’s optimistic efficiency figures, real-world tests often show poorer fuel economy, especially for the 1.5-litre turbo petrol variant.

Reported average: 28–32 mpg (compared to claimed 36–38 mpg).

Contributing factors:

• Aggressive DCT tuning
• Turbo lag and over-fuelling
• Weight of the SUV impacting consumption

Remedy:
Drive in Eco Mode, check tyre pressure monthly, and use high-quality synthetic oil to enhance efficiency.

Forward Collision Alert Glitches

Many drivers complain that the Forward Collision Warning System (FCW) activates unnecessarily, issuing false alarms even in low-risk situations.

Fix:
Have the system sensitivity adjusted via the MG diagnostic tool. Ensure the front radar sensor is clean and properly aligned.

Faulty Heated Seats

The heated seats — a luxury feature in the MG HS — have shown issues like inconsistent heating or complete failure.

Causes:

• Defective heating elements
• Faulty seat control module
• Wiring disconnections under the seat

Solution:
Replace the seat heater module and ensure wiring harnesses are correctly secured to prevent future faults.

Maintenance and Prevention Tips

To keep the MG HS reliable, preventive care is vital.
Here’s what every owner should follow:

• Change oil every 10,000–12,000 km or once a year.
• Replace transmission fluid regularly (especially for DCT models).
• Inspect suspension components every 20,000 km.
• Update software for infotainment and ADAS annually.
• Wash sensors and cameras frequently to maintain accurate readings.

These small actions can prevent most of the common MG HS problems from recurring and help retain resale value.

Final Verdict on MG HS Reliability

Despite its flaws, the MG HS remains a value-packed SUV offering excellent equipment for the price. Most of its problems — electrical or mechanical — can be resolved through routine maintenance and timely servicing.

For prospective buyers, the key is to test-drive thoroughly, check for service history, and ensure all recalls and software updates have been completed. With proper care, the MG HS can deliver a dependable and enjoyable ownership experience.
