NHTSA complaint #11688742, filed 2025-09“Occasionally when putting the SUV in reverse, the car does not go into gear. I'll hit the gas and nothing and then all of the sudden it goes into gear. It's almost like it's in a delay sometimes I'll have to put into drive and then reverse for it to go into gear.”
NHTSA complaint #11441316, filed 2021-11“Check engine light came on and I noticed that the cooling fan would continue running for several minutes even after turning vehicle off. Had a mechanic run the diagnostics and the code came back as a thermostat/cooling issue. Although when I called to make an appointment and told him the issue and that it was a 2021 Traverse, he knew exactly what the issue was. He said that is a very common issue in all 2021 Chevy/GM engines. Online research provided a couple special coverages for repairs on 7 different GM vehicles from that same time period. …”
NHTSA complaint #11737628, filed 2026-05“I was unable to stop my vehicle from accelerating. The brakes were engaging but my vehicle continued to build speed. Myself and my family, as well as others on the road, were all put at risk due to my vehicle not responding or failing to control speed; cruise control was not engaged. My insurance company, USAA, is currently investigating and determining total damage estimate. No warning lamps, indicators, or messages were presented prior to collision. The rotors and brakes were glowing red after collision from continuous attempts to stop the vehicle.”
