Airbag System Malfunction

A critical recall (NHTSA Recall ID 20V024000) exists for the Air Bag Electronic Control Unit (ECU) due to inadequate protection against electrical noise, potentially disabling airbag and seatbelt pretensioner deployment. Numerous complaints also exist regarding airbag non-deployment. Estimated repair cost: Covered under recall.

Service Brakes Issues

Owners report issues such as grinding noises from rotors, inconsistent brake pedal feel, and squishy brake response. Some complaints also mention the Vehicle Stability Control (VSC) system causing unintended acceleration when the brake pedal is pressed. Estimated repair cost: $300 - $600.

Steering System Problems

Complaints include the steering wheel locking up unexpectedly, loss of power steering assistance at low speeds, and the vehicle pulling to one side. Some owners report alignment issues that seem to develop frequently. Estimated repair cost: $500 - $1,500.

Seat Belt Malfunctions

Some owners report issues with seat belts not latching correctly or not retracting properly. There are also concerns about seat belt pretensioners not engaging, particularly in conjunction with airbag issues. Estimated repair cost: $100 - $300.

Reports include jerky shifts at low speeds, stalling, and a general feeling of the transmission not shifting correctly, especially at higher mileages. Some TSBs address CVT-related issues like diagnostic trouble codes for torque converter clutch pressure control solenoid performance. Estimated repair cost: $1,500 - $3,500.

Rodent Damage to Wiring Harness

The soy-based coating on the wiring harness can attract rodents, leading to chewing and exposure of internal wiring, which can cause various electrical issues. Estimated repair cost: $200 - $1,000+.
