general problems of the 2019 Buick Enclave

Anc module is faulty after hvac condensation entered the unit causing it to not work making all speakers nonfunctioning.

We were on a trip home from the holidays about 400 miles away when we heard a huge explosion! the front sunroof exploded and rained glass all over us. It was a clear night with no other cars around. We had to pull over and find something to cover over the sunroof because it was so loud and shooting bits of glass all over us and our dog. We made it home. We are still waiting on insurance to fix it. This really scared us.

This vehicles exhaust system has two brackets that broke off the exhaust due to bad welds. There is TSB out for one of the brackets where they replace one cheaper pipe but no mention of the other. This TSB is for multiple years same issue, 2019, 2020, 2021 and 2022. Yet I was told mine is not included by dealer over the phone. There are literally thousands of complaints stretched across multiple sites with the brackets breaking off and exhaust leaking into the car after. This issue is right at the back of engine. It’s leaking exhaust right into the cabin from the venting system to the point we get sick now. It’s $800 I was told to fix the 2 pipes that are faulty. Just bought this 2 years ago and have owned many gm vehicles in last 35 years not one has ever had any issue with the exhaust system. And the one pipe that broke and cost $420 for just the part is also on back order cause they have replaced way more then normal and it’s also the part that’s not under any TSB yet.

Rear door with the automatic open/close feature. While accessing the rear portion of the vehicle (looking in boxes, accessing under floor storage compartment,etc) I have experienced on several occasions where the door starts to close. I was able to turn around, push the door upwards and the door stopped closing and reversed to the open area. This happened to our Buick Enclave that we own in canada. The dealer was able to find on Buick's database where this was documented and the suggested solution was to "turn this feature off using the "control knob located in the driver's door". My wife and I are 80 and this feature was one of the reasons that we purchased this model new in may 2020. So solution that Buick has offered is not the greatest. However, my wife is disabled and if the rear door had started to close on her, I do not think that she could have stopped the door from coming down. I will be notifying the canadian highway vehicle association of this problem. But seems to me that Buick has a problem with the design of this system and is not addressing it. Are you aware of this problem with Buick Enclaves 2018 -2021 in the USA? [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

My husband had the key in his pocket upstairs in our house. It accidentally activated at some point by his bending /sitting. The car remotely started and we did not hear it. Only because our pets became upset did we discover the running car in our closed garage. We were able to turn it off and vent the garage of CO accumulation.

Broken rear sunroof clip to hold sunroof shut close there is no replacement part and sunroof stays open!! part was made out of plastic and im sure more people have broken theirs too especially if they have kids.

After the vehicle is started, with the engine running, if a door is closed or opened/closed anything plugged into the aux outlet will short out and reset (I. E. Radar detector will reboot as if power supply was interrupted) and/or if the factory installed dvd players are powered on, they will turn off. Does not qualify under the lemon law because gm has been investigating a similar issue since 01/24/2019 with no current resolution or path forward. Gm advises dealers to attempt no repairs at this time and expect the consumer to "live" with a potential electrical short in the vehicle. Gm pit5653 explains a portion of the issue, but not all. Pit5653 applies to (10) different gm manufactured vehicles.
