Steering assist reduced “this is lane departure steering assist not working” Parking brake. “not working” Also cruise control is not working Buick service tells me this has happened often enough in other vehicles that there is a repair bulletin on it. Also the initial cost to repair is $3000 + if this bulletin repair fixes the problem if not there would be more costs. This vehicle is within the 36 month bumper to bumper warranty period but has recently exceeded the 36000 mile warranty threshold. I have already paid for the initial part so it could be ordered.

While driving at highway speeds, with cruise control set the vehicle started to violently shake almost causing me to lose control of the vehicle. After having the vehicle inspected I was informed that the transmission is known to have an issue with the 3rd and 5th clutch pack causing the vehicle to shake when they are trying to engage. This is no lights on the dash and no other warning signs of said issue. I have an appointment to have the issue resolved which entails to have the transmission either rebuild or replaced.

I was driving on a state highway with open fields on both sides. There were no other cars or trucks on the road. Clear blue sky and the temperature was about 50 degrees. No windows were open in the car. I was on cruise control at 62 MPH. There was what I can only describe as an explosion sound something close to the sound of a 45acp pistol discharge.. Luckily I had the sun screen closed or I would have had glass everywhere. The front sunroof had exploded and there was a 18" hole in the middle of it. The force of the break went up, meaning the edge of the broken glass was raised about an inch and a half above the rest of the glass and window frame. That kind of a break is caused by stress not from something like a stone hitting it.. The car was purchased in august so the car is only 4 months old. I immediately drove the car to bergstrom motors in green bay, wisconsin, for them to fix it. They took pictures. Service managers name is [xxx]. He has all the information. There is no police report. [xxx] got back with me today, december 10, 2020, and told me buick would not pay for the repairs because it's glass. I was told the repair would be about $1000. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

We purchased a 2011 buick enclave for what we thought was a great deal. We were prepared to pay for basic maintenance right after purchase. The check engine light came on as we were driving on the highway. I noticed loss of power while on cruise control(set at 65mph) and the vehicle started shaking. I noticed the RPM jumping from 1 to 2 . We took the vehicle to buick for repairs. We had a tune up, 2 catalytic converters replaced, 3 o2 sensors replaced along with one other one that I'm not sure the name, oil change, struts and shocks, rear sway bar links, air filter, and a gasket manifold. We have not had this vehicle longer than 2 months. The vehicle is still doing the same thing. Today after we picked it up from the shop(no check engine light) we drove it on the highway and now the service traction control light is on along with stabilitrak control. We have 6 children. This is dangerous. What are we to do?

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.

Car accelerated on it's own during highway speeds. Was traveling on a 2 lane highway in the desert at 70 MPH in #1 lane, attempting to pass a semi truck, went to the #2 lane increased speed up to 75, let off gas once I was back in #1 lane and my car was at 5 RPM when typically it's at 2 RPM or less. My car was increasing speed on it's own & the brake had no power. I used my other foot to kick up the gas pedal and I was able to control my speed again. Very scary situation. No warning lights nor codes to indicate problem. Had my cruise control turned off at that time. Contacted buick,explained what happen, they gave me a case ref# and will be towing it to the buick service to have them look at it. I have been in a car when I lost power, but never lost control of the throttle being in full power. Lucky to be alive to tell my story and grateful I didn't kill or hurt anyone on my path. Hoping buick fixes this issue so no one has to be in a dangerous situation.

Driving at interstate speeds with cruise control on, set to 80mph. After hitting a ridge at edge at edge of bridge, the vehicle suddenly shuttered causing vehicle to automatically shut off cruise control and decelerate quickly. I went from going 80mph to 55mph in a short amount of time. After touching the gas to try to maintain speeds, car suddenly shifts into a neutral position pushing engine to red-line, then shift into 5th gear roughly. The vehicle from this point on, had issues shifting into 3rd and 5th gears. This car had absolutely no prior issues with the transmission prior to this date. I had the car serviced and completely checked out by a mechanic for any mechanical issues a few days prior to this trip. I took it to the dealer, who fixed two separate transmission plates and replaced the transmission module. I was guaranteed by the repair shop manager that I would have no further issues with the transmission. Little did I know, I should have gotten that conversation in writing. I continued to have hard shifts after the repair, only to be told that's the transmission module sensing how I drove. Less than one week later, transmission completely failed, leaving my wife stranded on the side of the road with the vehicle unable to not shift out of 1st gear, forcing me to call a tow truck to bring it to back to the dealership. Now they are telling me I have to replaced the entire transmission, all at my cost. After paying for the plates and module to be replaced less than a week prior, now they want to again replaced those parts with a completely new transmission. If I were being followed too closely by another car or semi on the interstate, I would have been rear-ended. If that were the case- there wouldn't be a complaint, but a lawsuit. Get this transmission issue fixed. I have read countless stories of the same exact problem.
