Airbag System Malfunction

Complaints indicate potential for airbags and seatbelts failing to deploy or restrain during significant impacts, including rear-end collisions and rollovers. This is a critical safety concern. Estimated repair cost: $500 - $1500.

Fuel/Propulsion System Issues

Reports include fuel line corrosion and potential for severe internal engine damage, evidenced by metal particles in the oil, occurring at relatively low mileage. This suggests a risk of catastrophic powertrain failure and potential fire hazard. Estimated repair cost: $300 - $1000.
