Was driving home from work and my brakes suddenly stopped working, if I press all the way down on the brakes they somewhat work. Checked brake fluid and brake lines and everything seems fine. Could this be from vacuum power brake assist fail?

Increased stopping distance during certain brake vacuum loss events. My check engine light goes on and off periodically. When I’m at a red light my whole car shuts off and goes into a neutral mode then once I press the brake it starts back up.

SEAT BELTS,SERVICE BRAKES,AIR BAGS — Filed 08/14/2023

On Monday, August 14th, at approximately 5 pm, my wife and I were traveling in our 2018 Buick Regal towards a red streetlight. I began applying my brakes to come to a stop. I was several car lengths behind a vehicle that was up ahead. My car's engine then revved up and our vehicle kept on going and jerking front and back although I was applying the brakes. Our car failed to stop so I struck the stationary vehicle. I kept on applying the brakes, but the car kept on going and jerking until I struck the car in front a second time. Our vehicles engine continued to revve up and the brakes continued to fail and I struck the rear end of the car in front of me again. The other driver crossed the intersection with us traveling right behind with no control over our vehicle. When we crossed the intersection there was an incline, so this slowed down our car since our brakes did not work, I pulled the steering wheel to the right towards the cement curb, then I put the transmission into Park, then the car's engine revved up once again and made a loud noise. Both vehicles sustained damage. I then was able to turn the engine off. This action was the only maneuver which stopped our car. Both my wife and I had injuries which we were checked at a hospital emergency room. We have our vehicle parked at our home's driveway and it it available for inspection. The fact that our vehicle's brakes failed to function placed me and my passenger and others at risk. My wife called our dealership the following day, and a manager stated we needed to report this incident. Our vehicle has not been inspected at this point. There were no symptoms of the problem that appeared other than the engine making a sound like increasing in speed and the brakes failing. At the hospital I was diagnosed with a concussion. My wife was diagnosed with neck pain since her head kept snapping back and forth and hitting the dashboard area and the headrest. The seatbelts plus the airbags also failed to properly function.

SERVICE BRAKES — Filed 09/10/2022

September 10, 2022 I was backing out of my driveway, but the car would not slow down, and I hit a tree on my neighbor's easement across the street. After a minute, I decided to move the car, put the car in drive, and again the car would not slow down, and wound up hitting the porch of my neighbor 2 houses over. I have used my left foot for braking since 1966, so it is not a case of mixing up pedals. My wife called 911, the police and ambulance showed up, and I was taken to the hospital. After x-rays, ultrasound, and 2 CT scans, it was determined that I did not have a brain bleed and I was sent home. The car was towed, examined by the insurance adjustor and body shop, and determined totalled. There were no warning lights, and only later that night did I remember that I had received a recall letter.

The check engine light is always on and has not been diagnosed (as of yet) by Circle Buick - Highland, IN. There is an auto-engine-shutoff feature when the vehicle stops at traffic lights, and when you resume driving there can be a lengthy delay and/or an engine & transmission jolt after the brake pedal is released. The vehicle must be retested every two years for emissions compliance for IN, but cannot do so because of the check engine light never going off. This is a safety issue not to get hit from behind in local traffic. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
