Brake Shudder/Warped Rotors

Frequent complaints of brake shudder, often attributed to warped front rotors. This can lead to a pulsating brake pedal and reduced braking effectiveness. Estimated repair cost: $350 - $600.

Electrical System Issues

Reports include intermittent issues with the key ignition switch and failures of door lock actuators. These can affect vehicle start-up and security. Estimated repair cost: $200 - $450.

Engine Oil Leaks (Camshaft Tower Seals)

Oil leaks from camshaft tower seals can drip onto the exhaust manifold, creating a potential fire hazard. This is more common on higher mileage vehicles. Estimated repair cost: $700 - $1000.

Electronic Stability Control (ESC) / VSC Lights

Intermittent illumination of ESC and traction control warning lights, sometimes coinciding with braking system issues. This can indicate problems with sensors or system calibration. Estimated repair cost: $100 - $300.
