2017 Buick Regal Brakes Problems

Noticed a recall regarding Buick Regal concerning break issues causing the valve to not operate correctly. Possibly the electronic break module not working properly and an update needed along with some parts. Recently the break valve was replaced because the break assist failed. Now, after running the vehicle for more than an hour or sometimes two, the same thing happens. My thoughts are that this affecting more vehicles than just the ones that were recalled.

I was driving on the interstate going up the mountain and my 2017 Regal started to choke going up the incline. I was pressing my gas to the floor and nothing when this happened I quickly pulled off to the side when I tapped my brakes they felt as if I was pressing on a concrete block. I was able to stop but it was pretty scary. I had no cell phone reception going up this mountain in the dark late at night, I had to slowly drive the car home which was a good 20 minutes to go. Turns out according to my dad my brake vacuum pump busted apart so he replaced the part, he bought a GM certified part. This happened again just this past week it’s been a month and a half since the first incident. I had to spend $600 on the same part and I took it to the dealership this time. The mechanic said the part I had gotten must’ve been a faulty part he couldn’t see what the issue was and why it again for the 2nd time going up the same mountain pretty much at the same spot it happened the first time. The only difference was this time I had no other issues happening I was using cruise control hardly used my brakes the entire trip when I pulled off the exit I tapped my brakes and again it was like I was pressing on concrete. Seems odd that this happened so close together. I’ve had a lot of issues with this car once it hit 100k in miles. Electrical issues, just weird random things happen briefly and then it’s fine.

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.

Vacuum Pump blew up forcing cam shaft sensor to blew out of engine and caused my brakes to fail. This happened at a stop sign. I proceed through the stop in front of a semi-tractor. Fortunately it was in front of the police station in(30mph) town zone and he was able to brake before killing me. My vehicle stopped before going through the front door of an auto shop, My Timing Cam is damaged and Shepherds is quoting $2600 to replace, plus an additional $800 already spent in replacing the vacuum pump. I’ve driven the car an additional 6 months with the cam sensor detached but the vehicle stalls when I slow or stop. This has caused additional hazardous situations. Person(s) will die if this defect is not addressed, it’s probably already happened. I have over 25 years in Automotive safety systems design and manufacture, this needs addressed immediately.

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.
