Electrical System Faults (Door Wiring Harness)

Intermittent electrical issues, including malfunctioning windows, unintended parking brake activation, and airbag warning lights, are often traced to corroded or damaged door wiring harnesses. This can lead to cascading failures in safety systems. Estimated repair cost: $300 - $800.

Airbag System Malfunctions

The front passenger airbag may not deploy due to issues with the occupant detection system, often linked to faulty wiring. This can result in an airbag warning light or the 'Passenger Airbag OFF' indicator. Estimated repair cost: $0 (Recall) - $1,000+.

Braking System Concerns

Includes unexpected automatic emergency braking (AEB) activation, brake squealing, and grinding noises. Wiring harness corrosion can also lead to unintended electronic parking brake engagement. Estimated repair cost: $400 - $1,000.

Battery Drainage / Start-Stop System Issues

Models equipped with the auto start-stop system have reported battery drainage issues, sometimes leading to premature battery failure. Estimated repair cost: $200 - $400.
