Widespread complaints include sudden power loss, stalling, and failure to start. These issues can stem from complex electrical or powertrain control module problems, or internal engine wear. Estimated repair cost: $2,000 - $5,000+.

Electrical System Malfunctions

Recurring complaints and recalls point to potential issues with the airbag system, including warning lights and deployment concerns. This requires immediate attention due to safety implications. Estimated repair cost: $500 - $1,500.

Complaints include steering pulling to one side, stiff steering, and in some cases, loss of power steering assist. Issues can arise from the electric power steering (EPS) system or suspension components. Estimated repair cost: $600 - $1,800.
