Airbag Inflator Malfunction

Recalls have addressed potential rupture or malfunction of driver-side airbag inflator modules. This is a critical safety concern that requires verification of recall completion. Estimated repair cost: $500 - $1500 (if not covered by recall).

Fuel Pressure Sensor Leak

A recall addressed fuel pressure sensors not being sufficiently tightened, leading to potential fuel leaks. This poses a fire risk and requires inspection and re-torquing. Estimated repair cost: $150 - $300.

While not a widespread documented failure, the 7-speed automatic transmission can develop issues with age and mileage, including rough shifting or failure to engage gears. Regular fluid changes are crucial. Estimated repair cost: $2000 - $5000+.
