I was going to work in the morning. I went to stop at the redlight right at my work but my brakes were very firm and wouldnt push down. My service brake warning came up on my dash and service engine light came on. I had to practically stand up and press as hard as I could to get it to slow down enough to not rear end the person in front of me. I thank God I wasnt going very fast and thankfully the light was turning green at the same time so I just slowly rolled thru and pulled it into my work parking lot. I had to call a mechanic, When he looked under the hood first thing he saw was oil dripping very fast out of my engine out of the side of the mechanical vacuum pump. They towed it to car dealer garage and I had to have it fixed. It was the camshaft-driven mechanical brake vacuum pump failed while I was driving it. It resulted in a sudden and complete loss of any braking assist and my brake pedal was hard as a rock like you couldnt get it to barely move. I had this replaced.

UNKNOWN- when driving onto a rough road my front end will shake violently, even the steering wheel shakes. Sometimes it will go on for about 1 minute + or -

My vehicle only has 81824 miles on it and I am having head gasket issues. I have a coolant leak into my engine. It is barely 7 years old. This should NOT be an issue in a vehicle this age with this many miles. I have seen that this has become a known issue with the 2018 Buick Envision and it should be a recall. I have had to refill my coolant reservoir 3 times since my oil change. A compression test has been run on my coolant system and there are no other leaks. Thus it is the head gasket.

Multiple Electrical parts became faulty starting with 3 tire sensors, then the front passenger airbag sensor, immediately followed by both rear sensor control modules. Milage at onset was approx 85000. Brought to dealer for dx due to my vehicle applying breaks when it shouldn’t, when auto start/stop was still on, the vehicle powersteering would stop working intermittently when going from a stopped position in drive to accelerating. Dealership ran diagnostics and determined the air bag control module is faulty and requires replacement of the entire seat to replace the sensor, as well as both rear sensors need to be replaced . This vehicle has been in no accidents. I had a second opinion completed with the same diagnosis. Now today- my OnStar system began blinking red and forcefully called OnStar twice. I spent over a half hour on the phone while they tried to reset the system and the car wasn’t responding as they would expect it to. There is something VERY wrong with the electronics of this vehicle, I dont feel safe in it . Please advise
