2018 Buick Enclave Electrical system Acceleration & cruise control Driver assistance

The vehicle is experiencing an intermittent but severe safety defect involving the StabiliTrak and Electronic Parking Brake (EPB) systems. While driving at operational speeds, the "Service StabiliTrak" warning light illuminates, immediately followed by the uncommanded, autonomous engagement of the electronic parking brake. When the defect occurs, the vehicle forcibly brakes itself and suffers a complete loss of throttle response, preventing acceleration. This creates a severe, immediate crash hazard, as the vehicle...

traffic, directly into the path of two tractor-trailers barreling down at highway speeds. This was the hottest day of the summer, and I was left in terror, fully aware that one wrong move would have ended our lives instantly. The fact that my child could have lost their only parent because of a mechanical defect is beyond unacceptable. The stress, fear, and trauma of this incident cannot be overstated - it was a near-fatal event that never should have happened. My mechanic has since confirmed the transmission is destroyed, with black metal fragments throughout - clear evidence of internal failure. Only two months earlier, in June 2024, the car passed inspection with no codes or signs of a problem. This was not wear and tear; it was a hidden, catastrophic defect. In December 2024, GM recalled more than 461,000 vehicles, including certain 2018 Enclave models, for transmission defects leading to rollaway and internal failure. Source: The Lemon Firm, 12/18/24 [[redacted]] ). My case mirrors the defect exactly, yet I never received recall notice. I demand GM confirm my VIN's inclusion and cover the full cost of repair or replacement. I barely escaped a fatal crash. GM must act immediately before lives are lost.

2015 Buick Enclave Acceleration & cruise control Engine & cooling

I started my car at a CVS parking lot. When I made a turn, the car was out of control and I couldn't stop or turn the car. My car hit other three cars in the parking lot and finally stopped. The OBD-II code check later indicated a "Engine misfire detected". I once got a recall letter from GM for the following issue. Not sure if this accident is related to this issue. "Inoperative purge solenoid that could lead to excessive fuel vapors entering the combustion chamber from the fuel tank. This condition could result in no start, idle stall and possible drivability issues such as hesitation." The good thing is nobody got hurt in this accident.

2015 Buick Enclave Acceleration & cruise control Brakes

While driving at highway speed, Service Traction Control/Stabilitrak warning comes on. Vehicle slows and if driver attempts to accelerate (using accelerator pedal), it causes severe lurching of vehicle. This makes the vehicle basically undrivable while in the middle of traffic. You must use emergency measures to pull over (potentially across multiple lanes) off the road and while trying to do that, you are in a very high risk state of being hit. The problem is reproduceable. The manufacturer and dealer service...

2020 Buick Enclave Transmission & drivetrain Acceleration & cruise control

I bought a 2020 buick enclave, (owned by gmc) with 6 miles on it, 1 week ago. Yesterday the check engine light came on and the car started jerking anytime the transmission switched gears. I called to try to get it in to a certified buick dealership to be looked at and nowhere can get it in for 3-5 days and none of the dealerships will give a loaner car until the time of the vehicle appointment. I contacted buick directly regarding this and they told me the same thing, that we can't get a safe driving vehicle, until...

the one we have can be looked at by a dealership and if we take it to an un-certified shop that it would not be covered. So now I am stuck with either driving an unsafe car 50 miles on the highway to work for the next few days or not being able to go to work. This is a brand new car driven straight out of the floor room! Buick is putting people's life at risk by insisting that we drive this unsafe vehicle on the highway until we can get it looked at! Looks like a huge lawsuit in the making!!!!! *Tr

2010 Buick Enclave Acceleration & cruise control

Twice within the past month when driving on the interstate while using cruise control my vehicle automatically started accelerating uncontrollably. Depressing the brake pedal did not disengage the cruise control or stop the car from trying to accelerate. In both cases I had the wherewithal not to panic, control the vehicle to the shoulder, put the car in neutral and turn the engine off. After restarting the car the engine immediately continued to accelerate and throttle up to 4000 rpms while still in park. ...

Fortunately, both instances occurred on straight stretches of interstate during less than crowded hours. I shutter to think if this occurred while my kids were driving. I am filing this complaint in hopes that if there are other cases of this happening we can make sure gm can fix this before anyone gets killed. I know other automakers had this problem and were able to correct it through recall. I contacted gm/buick with my concerns and they acknowledged that this is indeed a safety concern but since my warranty is expired there is nothing they can do but advise me to take it in for repair at my own expense. I have a video I took after the second occurrence once I was able to pull my vehicle over and try to restart it. I am not able to upload it through this form but I can send it upon request. *Tr
