Common Ford Fiesta Problems (All Model Years)

PowerShift Transmission Failures (2011–2016)

Among all Fiesta issues, nothing is as notorious as the PowerShift dual-clutch transmission (DPS6) fitted to 2011–2016 models. This gearbox became the centre of one of the industry’s most publicised scandals, with over 2 million complaints filed globally.

Symptoms

• Hesitation or shaking during take-off
• Jerky upshifts and downshifts
• Slipping when accelerating
• Shuddering under moderate load
• Transmission warning lights
• Loss of power or inability to engage gears

Many owners report vibrations so strong that they travel through the steering wheel and pedals during gear changes.

Root Cause

The DPS6 uses dry clutches, which overheat easily. Combined with faulty TCM software and mechanical defects, this results in premature deterioration, harsh shifting, and clutch contamination.

Fixes

Owners have attempted:

• Clutch replacements
• TCM reprogramming
• Output shaft seal replacement
• Full gearbox replacement
• Software updates

However, many report recurring issues even after repairs.

Manufacturer Support

• Ford expanded the powertrain warranty to 7 years / 160,000 km on affected models.
• Some owners may still qualify for reimbursements depending on region.

Door Latch Failure (2011–2014 Best Known)

Faulty door latches are one of the Fiesta’s most frustrating and widespread problems. Owners frequently report that doors won’t close, won’t latch, or unexpectedly open while driving.

Symptoms

• Door bounces back instead of latching
• “Door open” warning stays illuminated
• Alarm randomly triggers
• Doors open while driving (safety hazard)

Cause

The spring-tab latch mechanism degrades due to heat exposure, eventually failing to secure the door.

Recommended Fix

• Full latch replacement (affordable and straightforward for DIY owners)
• Check VIN for Ford’s recall, which affected nearly 250,000 vehicles in the US, particularly 2014–2015 models, even though earlier years recorded the most complaints.

Heater and Air Conditioning Problems (2011–2014)

HVAC malfunction is common in Fiesta models, especially in colder climates.

Typical Symptoms

• Heater blower stops working
• No hot or cold air adjustment
• AC never cools properly
• Fan speed becomes unresponsive

Main Cause

Models with manual temperature controls suffer failures in the blower motor resistor, which burns out and disables the fan.

Fix

• Replace the blower motor resistor
• Access is simple: located behind the glovebox next to the blower motor
• Typically a low-cost repair

This is considered one of the Fiesta’s easiest DIY fixes.

Radio and Sync System Failure

Another known Fiesta issue involves radio units that stop functioning, even after replacing the stereo.

Symptoms

• Radio won’t power on
• Sync freezes or resets randomly
• LCD screen turns off
• Amplifier or speakers cut out

Root Cause

Thermal stress causes deformation in the radio module board.

Fix Options

Option A — Module Board Adjustment

1. Remove radio module
2. Unscrew four silver torque screws
3. Slightly twist the board to restore contact
4. Reinstall

Option B — Fuse Replacement

• Replace fuses F10 and F19

Option C — System Reset
