2018 Buick Envision Complaint Log

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 -

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

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.

The Instrument Panel Cluster failed and is completely gone black. Due to the failure, there is no speedometer, or other safety notifications being delivered to the driver. The lack of knowing your current speed, the speed cruise control is set at, along with zero safety notifications is a huge safety issue for the driver and passengers, other vehicles on the road and pedestrians, etc. All of the alert features failed, including the forward collision warning, parking collision warning, lane keeping assistance, etc. The component was inspected by the GMC dealer's shop the vehicle was purchased through, along with another GMC certified shop. There were zero warning lamps, message or other symptoms of the problem prior to the failure. After reading numerous on-line Buick/GMC forums, it appears this same issue has been prolonged and on-going across multiple Buick years, makes and models.

Every time the car auto stops and turns back on the steering locks. So when the car starts you can’t turn the wheel. Also, while driving the car will lock and radio will shut off/ turn on. This happens like 1 to 2x a week. It is available for inspection. It could be very dangerous for me and others for needing to turning into places or even turning down the road. It hasn’t been confirmed or inspected, yet. There is only one warning lamp that flashes on for a split second, it’s no t/c. It just started flashing 3/26/23 not prior to incidents.

While driving my vehicle at 55mph on a country road, I went to brake, and then realized that I had no brakes. I had to coast to a near stop and put everything I had into pushing the little bit of brake pedal clearance left to the floor to come to a complete stop. I had NO warning signs or dash lights before this happened. Once I turned my car off and then back on, the service brake assist light came on, followed by the engine light. Had any cars been in front of me to stop, I surely would not have been able to stop with what little brakes I had left. My brake assist vacuum pump was removed, and inside there were many pieces of the part in there. This part is available for inspection. Again, had this happened in traffic or with anybody stopped in front of me, this would have had a completely different outcome. I had to have my vehicle towed 70 miles for repair. When the part was removed, there were no visible signs of any of the seals leaking.

On June 4, 2022 the radio bar showed a line in the middle of it and the volume of it would not increase. I could not hear anything. I tried everything even going into systems on the radio. Later that day it corrected itself and went back to normal. On June 18, 2022 the front passenger side window I put down approximately 1-1 1/4” and drove for maybe a half mile then decided to put it back up, it won’t move. I tried from both the drivers door control and passenger door, nothing. I looked in the manual and did what it stated to do, nothing, I got home turned off the car waited, turned the car back on and tried again, nothing. I called the dealership where I purchased the car and to my disappointment no service on Saturday. I have less than 35000 miles on this car no reason why I should be having issues.

While we were merging onto the highway, the steering wheel locked! I was going 50 MPH and I couldn't move the steering wheel left or right. We almost got into an accident, but I pulled my hardest on the wheel and was able to pull over. I shut off the car and turned it back on and it was OK, but under the wrong circumstances, this could've ended up real bad. Are there similar complaints on this vehicle?

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.

We bought our used buick envision essence in Feb 2021 from Scott Robinson Honda, Torrance, CA with 6,489 miles and 3 month warranty. The night we drove it off the lot the floor behind the driver's seat was wet and we thought it was from the prep (including shampooing the carpet) they said they had to do before we drove it off the lot at 9:00 p.m. The next day found that the matts in front were saturated in gasoline so threw them away. Since then whenever it rains floor becomes soaked each time. This causes windows to always be fogged up because of constant moisture in vehicle creating dangerous very poor visibilty and mildew we have to breath in causing breathing problems. We took the vehicle to our regular auto repair, Encinitas Foreign Auto who checked the moon roof, door windows, windshild and AC system and after hundreds of dollars still don't know where wet floors are coming from. Should not be happening with less than 7,000 miles on it. Buick is now feeling and smelling damp all the time and fogging up windows making it difficult to see. We feel the manufacturer needs to correct this defect on our vehicle as soon as possible. Thank you.
