Common Problems

Defective Takata airbag inflators pose a risk of rupture during deployment, potentially causing injury from shrapnel.

Owners report ongoing delays in receiving Takata air bag recall repairs despite receiving notifications from the manufacturer. The air bag inflators pose a risk of exploding during deployment.

The electronic steering lock and ignition switch fail, causing the vehicle to not start and steering to lock unexpectedly, leaving drivers stranded.

The electrical connector and wiring harness for the rear tail lights melt and corrode, causing lights to fail and creating a potential fire hazard.

The rear subframe corrodes and rusts through, leading to structural instability, loss of control during braking, and potential detachment of suspension components.

Electrical system malfunctions include power seat failure, fog light issues, and complete electrical failure during rainstorms.

A strong gasoline smell is detected after filling the tank, indicating possible fuel system leaks.

Fuel tank or gasket leaks cause a strong gas odor inside and outside the vehicle, increasing the risk of fire or explosion.

The interior door handles on the driver or passenger side break, making it impossible to open the door from inside the vehicle. This poses a serious safety risk in emergencies.

The transfer case or transmission fails, causing humming noises and requiring expensive repairs. This issue is reported to be recurring among similar models.

The electric power steering system malfunctions, causing the steering wheel to seize unexpectedly, making the vehicle difficult or impossible to steer.

Interior door handles break unexpectedly due to weak plastic construction, creating a safety hazard if occupants cannot exit the vehicle during an emergency.

The vehicle's ignition system fails to recognize the key fob, causing the car to be immobilized despite the key fob working for locking/unlocking. The steering wheel may also lock unexpectedly.

The front passenger side headlight and rear passenger side parking/brake light illuminate or flicker unexpectedly while the vehicle is parked.

Rear brake lines corrode and rust out, leading to brake failure and potential loss of control.

The belt tensioner seizes or fails, causing the serpentine belt to shred and damaging associated components like pulleys. This can render the vehicle immobile.

The airbag warning light illuminates while driving, indicating a potential fault in the airbag system despite no visible damage or incident.

Owners report the airbag warning light is illuminated, but dealers claim it is unrelated to the Takata recall, causing confusion and safety concerns.

Dashboard warning lights, including the airbag indicator, illuminate intermittently or remain on, indicating potential system faults.

The engine stalls unexpectedly at startup and while driving, often accompanied by battery failure warnings.

Tail light wiring assemblies catch fire or fail repeatedly, even after prior recalls, requiring costly repairs.

Seat belts either fail to latch properly or become excessively tight, posing a risk in the event of a crash.

The steering wheel locks unexpectedly, preventing the vehicle from starting and causing electrical systems to shut down suddenly, posing a risk while driving.
