2022 Buick Envision Brakes Problems

The contact owns a 2022 Buick Envision. The contact stated that while driving approximately 40 MPH and coming to a red light, the brake pedal was depressed; however, the vehicle failed to stop immediately. The contact shifted to neutral before the vehicle came to a complete stop. The engine continued to rev abnormally as if the vehicle was accelerating. After several minutes, the engine stopped revving excessively, and the contact was able to continue driving. There were no warning lights illuminated. The contact stated that excessive force was needed to depress the brake pedal. The contact stated that the failure was intermittent. The vehicle was taken to the dealer however, the dealer was unable to determine the cause of the failure. The vehicle had not been repaired. The manufacturer was made aware of the failure. The failure mileage was 21,000.

On Wednesday, 06/07/2023, my 2022 Buick Envision Avenir suddenly displayed a large number of error codes on the dashboard. I was able to quickly identify that the only operation of the vehicle that was impacted seemed to be the brakes as I had to exert a much larger effort to slow the vehicle than normal and it obviously took a much longer time to stop. I had the vehicle towed to Scranton Motors in Vernon CT and they have basically told me that they "can't replicate the problem" and that I should, "bring it back if it happens more consistently." As this is the brakes we are talking about, "happening more consistently " might end up in me not being able to bring it back due to a potentially fatal crash that may result from driving this vehicle for over an hour twice per day on my way to work. I have opened a case with Buick, and told the dealer that I do not feel comfortable picking up the vehicle at this point.
