Recalls
4 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Seat belts Vehicle recall #18V673000 · 2018 · 15,800 vehicles
What's wrong: Certain second-row or third-row rear seatbelts retractor assemblies May not automatically lock when the seatbelt is fully pulled out of the retractor, possibly preventing a child seat from being properly secured. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (fmvss) number 208, "occupant crash protection."
Why it matters: If the child seat is not properly secured in the event of a crash, it can increase the risk of injury.
The fix: Gm will notify owners, and dealers will inspect the rear seatbelt retractors and replace them if necessary, free of charge. The recall began November 7, 2018.
Exterior lights Vehicle recall #19V117000 · 2019 · 5 vehicles
What's wrong: Rotation of the steering wheel will not automatically cancel the turn-signals from flashing. As such, these vehicles fail to comply with Federal Motor Vehicle Safety Standard (fmvss) number 108, "lamps, reflective devices and associated equipment."
Why it matters: If the turn-signals do not automatically deactivate, the driver May fail to turn them off manually. An erroneous active turn-signal May mislead pedestrians and other drivers, increasing the risk of a crash.
The fix: Gm has notified owners, and dealers will replace the turn-signal switch. The recall began March 11, 2019.
Brakes, Stability control Vehicle recall #19V889000 · 2019 · 463,995 vehicles
What's wrong: Due to an electronic brake control module (ebcm) software error, the vehicle's electronic stability control (esc) and antilock brake system (ABS) May become disabled. Furthermore, if this specific error occurs, the vehicle's diagnostics will not illuminate the instrument cluster esc and ABS malfunction warning lights. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety…
Why it matters: If the driver operates the vehicle unaware that esc and ABS are not functioning, there is an increased risk of a crash.
The fix: Gm will notify owners, and dealers will reprogram the ebcm, free of charge. The recall began February 4, 2020.
Transmission & drivetrain Vehicle recall #25V148000 · 2025 · 90,081 vehicles
What's wrong: The transmission May become damaged internally and cause the wheels to lock-up.
Why it matters: Wheel lock-up while driving increases the risk of a crash.
The fix: Dealers will install transmission control module monitoring software, free of charge. Owner notification letters were mailed April 7, 2025.
