NHTSA complaint #11431435, filed 2021-09“This week I leased a white buick encore gx fwd in the preferred model. After driving off the lot I noticed the brakes are very hard to press down and I can’t stop the vehicle over short distances. This seems dangerous and my dealership says nothing is wrong with the car but I can tell something is wrong with the brakes and this isn’t how new brakes are supposed to feel. After googling the symptoms it seems to be a problem with the brake booster.”

Numerous lights came on, including: Brakes, ABS, Traction Control, Engine, as well as 2 others. A message came up on the screen that said, Brake System Failure, 62 MPH Top Speed. …”
