Recalls
2 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Transmission & drivetrain Vehicle recall #20V668000 · 2020 · 194,105 vehicles
What's wrong: The start/stop accumulator endcap May have missing bolts.
Why it matters: Missing bolts on the start-stop accumulator endcap could result in a transmission oil leak and May progress to a loss of propulsion, increasing the risk of a crash. A transmission fluid leak in the presence of an ignition source May increase the risk of fire.
The fix: Gm will notify owners, and dealers will inspect the start-stop transmission accumulator and replace it if any bolts are missing, free of charge. The recall began December 15, 2020.
Tires Vehicle recall #21V115000 · 2021 · 33,838 vehicles
What's wrong: The affected tires were cured for too long during production.
Why it matters: Over cured tires May develop a break in the sidewall resulting in sudden air loss or a belt edge separation which could lead to a tread/belt loss. Either condition can cause a loss of vehicle control, increasing the risk of a crash.
The fix: Gm will notify owners, and dealers will inspect the tires, replacing them as necessary, free of charge. The recall began March 22, 2021.
