Electrical, Visibility (wipers, glass) Vehicle recall #23V099000 · 2023 · 3,193 vehicles
What's wrong: When the digital key is removed from the vehicle, the electronic control unit (ECU) software May still allow the power windows and sunroof to be closed. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 118, "power-operated window systems."
Why it matters: Unintentionally closing the windows or sunroof without the key present can increase the risk of injury to occupants inside the vehicle.
The fix: Dealers will update the software for the electronic control unit (ECU), free of charge. In addition, the digital key function via cellular service and wi-fi capability will be deactivated until the vehicle is updated with new software. Owner notification letters are expected to be mailed April 11,…
Electrical Vehicle recall #25V644000 · 2025 · 145,102 vehicles
What's wrong: After repeated attempts, the starter motor May overheat from an electrical overload.
Why it matters: An overheated starter motor can ignite nearby combustible material in the engine compartment, increasing the risk of a fire.
The fix: Dealers will replace the engine starter, free of charge. This recall includes vehicles repaired under recall 24v576 and those owners will need to have their vehicle repaired again. Owner notification letters were mailed February 9, 2026.
Transmission & drivetrain Vehicle recall #26V525000 · 2026 · 27,720 vehicles
What's wrong: The connection between the driveshaft and the rear differential May become damaged, possibly resulting in a loss of power to the rear wheels or a vehicle rollaway.
Why it matters: An unexpected loss of drive power can increase the risk of a crash. In addition, a damaged driveshaft can result in a vehicle rollaway if the parking brake is not applied, increasing the risk of a crash or injury.
The fix: Dealers will inspect the connection between the driveshaft and rear axle differential, and apply adhesive or replace the driveshaft and rear axle differential, as necessary, free of charge. Owner notification letters are expected to be mailed October 2, 2026.
