NHTSA complaint #11374670, filed 2020-11, 46,500 miles“My Buick Envision started to occasionally create notable vibration in the front and traveling into the steering column. I brought the car to a GMC Buick dealership in Amite, LA(4/13/21) it was there for 3 days. The problem couldn't be duplicated. Next the car was brought to Royal Buick, Baton Rouge, LA(10/26-11/6/21.Having trouble controlling the car on each occurs.”
NHTSA complaint #11441122, filed 2021-11“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.”
NHTSA complaint #11661556, filed 2025-05“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. …”
