Engine Stalling/Power Loss

Frequent reports of the engine stalling or losing power, often linked to fuel system issues (fuel pump, high-pressure fuel pump), ignition system components (coils), or air intake problems. Check engine lights (EPC) are common. Estimated repair cost: $400 - $1,200.

Airbag System Failures

Recurring issues with the airbag clock spring leading to warning lights, horn malfunction, and loss of steering wheel controls, even after recall work. Estimated repair cost: $300 - $600.

Electrical System Failures (Water Ingress)

Water leaks from the sunroof drainage system can cause widespread electrical malfunctions, mold growth, and damage to interior components. Estimated repair cost: $200 - $1,500+.

Steering System Malfunctions

Reports of power steering failure, loss of assist, or steering wheel locking, often related to electrical control modules or the steering rack. Estimated repair cost: $800 - $1,500.

Ignition Coil Failure

Commonly reported, especially in cold weather, leading to engine misfires, rough idle, and check engine lights. Replacement of all four coils is often recommended. Estimated repair cost: $100 - $400.

High-Pressure Fuel Pump (HPFP) Failure

Symptoms include difficulty starting, weak acceleration, rough idle, and potential stalling. The cam follower is a critical wear item that should be replaced with the HPFP. Estimated repair cost: $600 - $1,200.

Water Pump Leaks/Failure

Leaks from the water pump or thermostat housing can lead to coolant loss and engine overheating. Replacement is typically recommended around 100,000 miles or if leaks are detected. Estimated repair cost: $400 - $800.

Some models may experience turbocharger problems, indicated by loss of power, whistling noises, or oil consumption. Estimated repair cost: $1,200 - $2,500.
