Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“When restarting after vehicle auto stop I am getting service brake assist and occasionally service ESC warnings. These warnings were associated with brake failure in GM SUV's and pickups and were subject to a recall. No such recall exists for the Terrain. I haven't yet experienced a brake failure but GM seems to want to wait until I do to fix the problem.”
NHTSA complaint #11397836, filed 2021-02, 34,000 miles“My 2018 Gmc Terrain brakes did not work when coming to a stop at stop lights which caused me to rear end the car in front of me. There was no warning on my SUV nor did I receive a recall on this matter. This happened twice to me in this same vehicle where the brakes did not respond at a low speed causing an accident. This accident just happened to cause damage to my vehicle and the car in front of me.”
