    General Motors LLC (GM) is recalling certain 2020 Chevrolet Corvette and Cadillac CT4, CT5 and XT4, 2021 Chevrolet Trailblazer, and 2020-2021 Buick Encore GX vehicles.

    Dealership, fixed brakes due to previous recall. Brakes continue to squeal and grind with every stop. Was informed by dealership that they can do no further repair because it is considered a noise and not a safety issue. Grinding brakes are a safety issue!!!

    2/3/2021 i was driving with my daughter today. She was driving and we were approaching a left hand turn at an intersection. We had a green light and i could see that her foot was on the brake. She started the turn with her foot still on the brake. The vehicle accelerated while her foot was on the brake and the steering wasn't responding. We hit a telephone pole. This vehicle was purchased less than 2 weeks ago and has less than 115 miles on it. This is a major safety issue.

    The brake assist continues to fail and is a safety hazard. It fails unexpected so often that it is dangerous and we are somewhat afraid to drive this vehicle. This issue began a few weeks after purchased. Request an urgent fix or the opportunity to return this vehicle for a different safer vehicle.
