Electrical System: Battery Drain

Owners report recurring battery drain issues, sometimes requiring jump starts or multiple battery replacements. This can indicate a parasitic draw within the electrical system or a fault in the charging system. Estimated repair cost: $300 - $1,500+.

ABS Module Short Circuit

A recall addresses a potential short circuit in the ABS module, posing a fire risk. While fuses may be replaced as a remedy, the underlying module integrity remains a concern for long-term reliability. Estimated repair cost: $500 - $1,500.

Tire Sidewall Failure

Complaints include tire sidewall failures and blowouts. While road hazards can contribute, this suggests potential fragility in the tire components. Estimated repair cost: $150 - $500 (per tire).

Air Conditioning System Failure

Some owners report AC system failures, particularly on hot days, with dealers unable to diagnose the root cause. This points to potential issues with HVAC control modules or refrigerant system components. Estimated repair cost: $500 - $2,000+.
