Buick Regal brake failure problems

Filed May 4, 2024 · Brakes · NY

After starting my vehicle with foot on the brake and putting the vehicle in gear it will move forward and occasionally roll for 4 or 5 feet before the brake engages. This is extremely dangerous as I'm pulling out of a parking space and merging with ongoing traffic !This has been going on for approximately three weeks. The vehicle literally has no brakes for four or five feet despite the fact that my foot being pressed all the way down on the brake pedal!! Last week I came very close to a major accident when I couldn't stop for an on oncoming car. Thank goodness the operator of the other vehicle stopped in time to avoid a serious accident! I immediately took the car to a local garage to have my brakes checked. They found no issues. I then took it to the Buick dealer,BICAL, and they found a serious issue. The brake vacuum pump had frozen and had actually disintegrated and no longer was functional. Parts from the pump entered the valve shaft area also. The end result was a $3,000 repair bill. The important issue here is the driver safety on the road.Although this was only occasional and at low speeds left unattended would lead to a total brake failure with major consequences and major fatalities!! God only know how many major accidents occurred with major consequences without anyone knowing the true source of the accident details. I have read online that 1996-1997 Cadillacs also have this same issue!! This is a very poor design and a major safety issue. After all there is no such thing as a minor brake issue!!! I'm avail to discuss this issue issue at your convenience. I can be reached on [XXX] [XXX] cell. Repair bill available.

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.

Brakes failed. This happened twice in 14 months. Vacuum Pump had to be replaced both times. The first time it happened it was sitting in a parking lot and we just started to pull out. The second time we were on a 4 lane highway in the fast lane and had to pull the car over through the lanes to the berm of the highway. No warning lights came on and no problems beforehand. The car has been well maintained and kept up to date with all maintenance.

Three years in a row starting in 2020, the vacuum pump has gone out causing the brakes to malfunction (NO BRAKES). In 2020, I was coming off the freeway when the brakes went out. In 2021, the brakes went out on my daughter. June 2022, brakes out while grandson was driving. No accidents or injuries occurred. Just frazzled nerves.

I was driving down the highway at 75 mph with my kids in the car and the vacuum pump for the brakes went out which caused my brake pedal to seize up and car brakes would not work while in traffic. I was barely able to get off the highway and get the car to stop. This issue with the pump failing also put debris into the motor and caused motor failure. There was no warning lights on the dash and car was running normal and then all the sudden no brakes out of nowhere. Car is now in a mechanic garage to be fixed. This issue put not only my life and my childrens lives in GREAT danger but also the drivers around me. GM currently has a massive recall for this same issue on other models but my Buick regal is not on the list.

Driving my car at around 30mph, the car completely shuts off without warning. There is no shutter or sound. It is just suddenly completely turned off. No brakes. No power steering. No gas. You must pull the car over. Come to a complete stop. Put the car in park. Turn the key completely off, and then the car will restart almost every time. This has happened to me 5 times in the 9 years that I have owned it. But it has happened 3 times in the last 3 days. No mechanic nor the dealer can identify the problem. I have replaced the serpentine belt twice, and the throttle body/throttle position sensor.

Off and on over the past 6 months, there was a loss of brakes directly after startup. After 30 seconds or so, the brakes would function normally. This car is normally garage kept. Walking to the car at night to leave, I noticed oil on the garage floor coming from under the car. After opening the hood, I noticed oil in the engine compartment coming from the top of the engine. After removing the plastic engine cover, I saw that the oil was coming from what I learned is the vaccum pump. There was a visible break in the pump housing. I went to my local dealership to inquire about getting this serviced under warranty. They started that this part is only covered under the bumper to bumper warranty and not powertrain warranty, even though the vacuum pump is directly mounted to and connected to the intake camshaft. My bumper to bumper warranty had expired 3 1/2 months or 219 miles prior, yet the car is still under the powertrain warranty. The dealership was unwilling to help and quoted me $104 for a new AC delco vacuum pump. I was able to order a new AC delco vacuum pump from rock auto for $43. After receiving the new pump, a mechanic friend was helping me to replace the pump. When the old one was removed, it was shown to have disintegrated. The inside of the part was in many pieces. The part that engages the camshaft was also broke into pieces and at this point I believe that several of those are now inside the engine. At this point I am going to take the old part to the dealership, along with photos of the engine and demand that this is now fixed under the powertrain warranty, as the powertrain is directly affected. Had this happened while driving, the loss of brakes could have been catastrophic.

The throttle body has a defect which shuts off all power to vehicle with no notice. The engine and transmission lock up you lose all steering control and no brakes. Also no lights so when it happens at night it is pitch black. Gm does know about the problem and when I questioned them about the loss of life like what happend with the chevy cruze all members of gm are told to hang up the phone. It has happend on several occasions and the dealership sent me back on the road knowing the problem. Dealer rep said if I was a better customer thay may have done more for me.

My daughter drives our 2011 buick regal cxl that we purchased in february 2016. In the last several month the vehicle has stalled, steering locks up, brakes go completely out, it doesn't have an electrical and because it has an electric emergency brake there is no way for her to stop. The first two times she was driving around town and the last time it happened was last week at 70 MPH on the highway. She almost hit the car in front of her. Once it coasted to a stop she was able to start it and continue on. This gm vehicle 2011 buick regal is a death trap waiting to happen. Don't buy a buick!!! I picked it up from the local buick dealer yesterday and they can't do anything. Once the vehicle is restarted after one of these incidents the computers automatically resets and wiped clean of codes without any trace of a problem or issue. All the errors completely disappear. The service person at the dealership asked me if I had a decoder I could plug in right after it happens. This problem is all over the internet and buick does nothing. You can bet that a gm executive would decline an offer for one of his/her family members to drive it for a while. Make no mistake these cars shut down completely without any warning and absolutely nothing works at the moment. No steering, no brakes, stalled engine, and no electrical. Absolutely nothing!!! All buick says base on online comments is sorry. Sorry for what? Killing people? Not giving a [xxx] about my family or yours? If they were sorry they'd step up and do the right thing before its too late and someone dies. Insurance companies are probably paying out lots of money to their insured and the people they hit, injure or kill. I bet they would love to hear more about this issue. Be carefully what you buy because you might be surprised by your car right before you crash. I've always likes gm and buicks but not anymore.
