I am the original owner of this Buick Enclave Avenir. I have had two near accident occurences when the car started foring the breaks while I was accellarating on the highway and was not behind another vehicle. The car behind me nearly rerended me. On 10/17/26, my purge valve was replaced for the third time, making this the fourth purge valve the car has had. After getting gas, the car will not start, which is an indicator the part has gone bad and needs to be replaced. In June of 2025 I took my car to Anderson Buick over concerns while accellerating. They confirmed my transmission needed to be replaced. Our family shop suggested waiting until the end of summer since I wouldnt be driving daily and the replacement would cost nearly 10k. It could only be ordered through GM, making the part substantially higher in cost. When summer break ended and I needed to use my car daily we could not take the car to the dealer or our family shop because the part was no longer available. We could not get a clear time frame of when the part would be in stock, if at all. We had the transmission rebuilt with 166k miles. Nearly 4 months later the trasmission started to shudder again. We took it back to the same shop for repairs becuase it was under warranty. Nearly four months later, the issue began again. The shop said there is nothing I can do to stop it from happening, that the part is deffective and GM knows. I have opened a claim with GM and expect nothing will happen, but it is apparent that the transmission issues are rampant with this vehicle, as evidenced by the complaints here and the droves of complaints on reddit forums.

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.

I was driving my vehicle when it suddenly stalled and would not start, I had it towed to a mechanic and was advised it needed an engine, this was a known problem with the 2008, 2009, 2010 buick enclaves, because of the oil pump draining the engine of oil it seized the engine. I called gm and asked why they haven't recalled the 2010 along with 2008, and 2009 models with the same engine and issue. They said its been acknowledged but there is no future date if or when the 2010 buick enclave would be recalled for the engine- oil failure! This cost over $4800 dollars to get fixed, I just purchased the car from a dealership less than a year prior, very disappointed with dealer for not making me aware to check oil every few days so this wouldn't happen. I also just had the oil change done a month before the engine seized!

Left my house it was fine. I stopped and turned it off and waited for my family member to come out of an appt. I tried to start the vehicle and wouldn't turn over and only clicked like the battery was dead,it also wouldn't let me remove the key. Then I got a jump start and it started right up. After I was home I tried starting again and it did. I just don't trust it now.

I purchased the vehicle on 11/4/19. The dealership, salesman or service department. Didn't inform me or put it in writing that the crankshaft sensor was faulty on the vehicle. John eagle acura didn't consider safety first. On 11/7/19 at 48,076 miles the vehicle won't crank. It was cold and rainy so I didn't drive the vehicle. On 11/17/19 I drove the vehicle to church at 48,124 miles. When I got out of church it won't crank. I called the dealership on 11/18/19 and told them about the vehicle. They told me to bring it in. I brought it in on 11/19/19 at 3p.m. I asked the service department what was the problem because the vehicle won't crank. They told me that it is the crankshaft sensor. I told the salesman that you knew it was the crankshaft sensor and you put my safety at risk. Because you and the service department and dealership knew that the crankshaft sensor was faulty and my safety was at risk. He said to me and my husband that he knew and said that he should have given me a loaner car. But he never told me about it.

On 3 occasions, while the car was driven, the car stopped without warning. On all three occasion, the car will not start. The first time this occurred, I took the car to the dealership, carl black roswell. They replaced the starter and replaced all the fuel injector. 2-3 days after the car was picked up, the car stopped again while my wife was driving our kids to school and the car wouldn't start. The car was towed to the dealership again. This time, they said they replaced the fuse block. A few days after I picked up the car from the dealership, the car stopped again while it was driven and the car wouldn't start after it stopped. The car again was towed to the same dealer. They then said they fixed the ground wire. They said they could not guarantee me that the issue will not re-occur. I was concerned for the safety of my wife and kids since my wife uses the car to drop off and pick up my kids to/from school. I contacted gm (through email to the ceo, mary). Gm reached out to me and their claims department contacted the dealership. Gm indicated that they had approved all the 3 repairs (including the 2 repairs that did not fix the issue) and asked me that there was nothing else they could do. I asked for a guarantee the issue will not re-occur and gm said they could not guarantee me that the issue will not reoccur. I then reached out to gm's ceo via email again and asked for a guarantee or replacement of the car with a certified used buick enclave or new buick enclave. Its been over a week and I have received no response. I have been renting a car for my wife to take the kids to school for almost a month and it has cost me about $800 to date and I am still renting the car. The buick enclave is still at the dealership at the current time. The dates the 3 incidences occurred(I.e. Car stopped):2/11/2019, 2/22/2019 & 3/18/2019. I attached invoices for 1st two incidences.
