Electrical System Failures

Frequent complaints involve intermittent power loss, stalling, and malfunctioning accessories. Issues can stem from wiring harness problems, control module failures, or sensor issues. Given the high complaint volume, this is a significant concern. Estimated repair cost: $300 - $1,500+.

Steering System Issues

Complaints include loss of power steering assist and, in severe cases, steering seizure. A recall addressed a power steering hose that could melt near the catalytic converter, posing a fire risk. Thorough inspection of the power steering system is crucial. Estimated repair cost: $500 - $2,000+.

Electronic Stability Control (ESC) Malfunctions

A significant number of complaints relate to the ESC system activating unexpectedly or failing. This can be due to faulty wheel speed sensors, steering angle sensors, or issues with the ESC control module. Estimated repair cost: $400 - $1,000+.

While less frequent than electrical or steering problems, engine complaints include noises, rough idling, and occasional stalling. Issues can range from minor sensor failures to more significant internal component wear. Estimated repair cost: $500 - $3,000+.

Complaints involve brake fade, pedal drift, and issues with ABS or traction control systems. Regular inspection and maintenance of the braking system are essential for safety. Estimated repair cost: $400 - $1,000+.
