2022 Chevrolet Blazer Complaints

  • Power Train 07/15/2026

    I have been smelling engine coolant for some time and found a leak on the drivers side top seam where the aluminum meets the plastic tank on the radiator. This is a known problem with 2019=2026 Chevy Blazers by GM and it still hasn't been resolved. After researching, I have found numerous Blazer owners that have this same issue and some are on 3rd and 4th radiator replacement. I am afraid to drive the vehicle due to the leak that could leave me and my family stranded on the side of the road. I am also concerned about a major leak or seam separation that could allow a large amount of coolant out that could get on the tires and cause loss of vehicle control as a result. Also, the leaking coolant is a hazard to any animals that are around as the coolant puddles under my vehicle after driving. At this point, the Blazer is running hotter and I had to add coolant. I just called to price a new radiator...$450 and install...$1,025...that isn't a cost I should have to take on with GM kn...

  • Engine And Engine Cooling 06/30/2026

    The contact owns a 2022 Chevrolet Blazer. The contact stated that the coolant was leaking from the radiator. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the radiator needed to be replaced. The contact was informed that the dealer was replacing a lot of radiators for similar failures. The vehicle was not repaired. The manufacturer was contacted, and a case was opened. The failure mileage was approximately 49,500.

  • Fuel/propulsion System 06/11/2026

    Car stalled and told me to put in neutral. Could smell gas. Car wouldn't come back on. Code u18a2 (lost communication with fuel pump communication module), part is available for inspection, we were all at risk due to the car stalling on the highway with no prior warnings, check engine light came on after car stalled, ordered new part from GMC, fix the issue right away. This part has been recalled on other models just not on 2022.

  • Power Train, electrical System, engine 05/19/2026

    BROUGHT MY CAR TO CHEVROLET CENTER IN WINTER HAVEN FLORIDA BECAUSE I HAD 2 DIAGNOSTIC CODES SHOW UP WITH A CHECK ENGINE LIGHT, THE CODES WERE (U1345: Indicates a communication fault on the LIN (Local Interconnect Network) Bus, usually tied to modules like the active grille shutters, cooling fans, or charge air cooler (CAC) pump.U0632: Indicates lost communication specifically with Cooling Fan 1.) THE DEALERSHIP TOLD ME THEY DIDN'T FIND ANY CODES IN THE SYSTEM AND THEY TRIED TO CHARGE ME $165 FOR A DIAGNOSTIC FEE. RIGHT AFTER I LEFT THE DEALERSHIP I WAS HAVING THE SAME CODES POP UP, WITH THE CHECK ENGINE LIGHT AND MY CAR WAS OVERHEATING. CHEVROLETS ECM/PCM WARRANTY IS 8 YEARS OR 80,000 MILES.

  • Unknown Or Other 05/22/2026

    Thermostat fails resulting in steering power reduced, temperature goes to C and fan runs overtime. This thermostat or temp sensor fails intermittently and fixes itself. Car could be overheating and you wouldn't know. This part is recalled on 2021 Blazers already.
