Recalls
4 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.
Transmission & drivetrain Vehicle recall #26V289000 · 2026 · 66 vehicles
What's wrong: A component missing from the drivetrain transfer case May cause the front and/or rear wheels to lock up without warning to the driver.
Why it matters: Front or rear wheel lockup increases the risk of a crash.
The fix: Owners are advised not to drive their vehicle until the remedy is completed. Dealers will inspect and, if necessary, replace the transfer case assembly, free of charge. Owner notification letters were mailed May 18, 2026.
