Recalls
3 vehicle recalls from the manufacturer. Repairs are free. Check your VIN to see if one is still open on your car.
Brakes, Brakes (hydraulic) Vehicle recall #19V761000 · 2019 · 652,967 vehicles
What's wrong: 3-liter engine, a 3.08-ratio rear axle and four-wheel drive. If a wheel-speed sensor fails, while the vehicle is traveling between 41 and 60 mph in four-wheel or automatic mode, the electronic-brake control module (ebcm) software May activate the driveline-protection system.
Why it matters: Unintended activation of the driveline-protection system will cause unintended braking on the wheel on the opposite side of the failed sensor, causing the vehicle to pull to one side unexpectedly, increasing the risk of a crash.
The fix: Gm will notify owners, and dealers will reprogram the ebcm, free of charge. The recall began December 11, 2019.
Fuel system Vehicle recall #19V837000 · 2019 · 502 vehicles
What's wrong: The fuel pump May be missing a pressure regulator, allowing for over-pressurization of the fuel system.
Why it matters: Over-pressurization can crack the fuel pump and cause leaks, increasing the risk of a fire in the presence of an ignition source.
The fix: Gm will notify owners, and dealers will replace the fuel pump, free of charge. The recall began December 18, 2019.
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.
