Roof Rail Air Bag Connector Defect
The harness connector to the left or right side roof rail air bag may have incompatible electrical terminals. This can prevent the side curtain airbags from deploying in a side-impact or rollover crash, significantly compromising occupant protection. There is no warning indicator for this condition.
NHTSA recall for 2020-2022 Traverse models. Dealers replace the harness connector to the roof rail air bags free of charge. Owners should contact their dealer promptly to schedule the repair.
Est. Cost: $0 (recall repair)9-Speed Automatic Transmission Issues
The 9T65 nine-speed automatic transmission can exhibit harsh shifting, shuddering, slipping, and delayed engagement. Owners report the transmission hesitating when pulling away from stops and hunting for gears during highway driving. In some cases, the transmission may fail completely, requiring replacement.
Transmission fluid service with updated GM-approved fluid. Transmission adaptive learning reset and TCM software update. Reference GM service bulletins for 9T65 transmission calibration updates. Torque converter replacement for persistent shudder. Complete transmission replacement for internal failures.
Est. Cost: $300 (fluid service) - $5,000 (transmission replacement)Shift-to-Park Warning Message
Owners report receiving a persistent 'Shift to Park' warning message on the driver information center even when the vehicle is properly in Park. The vehicle may not shut off or allow key removal. This is caused by a worn or faulty transmission range selector switch in the electronic shifter assembly.
Replace the transmission range selector contact switch or the entire shifter assembly. Clean the shifter contacts as a temporary fix. Dealer software updates may also help recalibrate the park detection system.
Est. Cost: $200 - $800Premature Brake Wear and Noise
Owners report premature front brake pad and rotor wear, sometimes requiring replacement before 30,000 miles. Symptoms include grinding, squealing, or pulsation during braking. The issue may be related to caliper slide pin binding or rotor warping from heat.
Replace brake pads and rotors. Clean and lubricate caliper slide pins. Inspect caliper pistons for proper retraction. Upgrade to premium aftermarket brake pads with better heat dissipation for longer life.
Est. Cost: $400 - $1,000 per axleClimate Control and HVAC System Failures
The automatic climate control system may stop blowing air, blow only hot or cold air regardless of settings, or fail to direct airflow to the selected vents. Some owners report the rear HVAC unit failing independently of the front system. Blend door actuator failure is a common root cause.
Replace the faulty blend door actuator(s). Recalibrate the HVAC control module. In some cases, the HVAC control panel itself may need replacement. Inspect the cabin air filter for blockage.
