general problems of the 2016 Buick Enclave

I purchased this used 2016 Buick Enclave in July 2026. Shortly after purchase, the vehicle began repeatedly jerking and hesitating while driving. During occurrences, traction control/stabilitrak warnings appeared and the vehicle experienced loss of power and difficulty accelerating normally. I reported the jerking/drivability problem to the selling dealer. On July 27, 2026, the selling dealer attempted a repair after I reported the jerking/drivability problem. Within approximately five minutes of leaving the dealership, the vehicle began jerking again. I then took the vehicle to an auto-parts store, where an obd-ii scan produced multiple diagnostic trouble codes, including p0300 engine misfire and several map-sensor-related codes. I have photographs documenting the scan results. The vehicle became disabled shortly thereafter and required towing. It was subsequently evaluated by an independent repair facility, where the map sensor was replaced. The vehicle later again experienced the jerking/loss-of-power condition and stabilitrak/traction control warnings. On August 10, the vehicle became disabled again. These incidents have occurred while driving in traffic. When the condition occurs, I cannot reliably accelerate or maintain normal vehicle operation, creating a safety concern because I may be unable to move safely with surrounding traffic. The specific cause is unknown. The vehicle has been evaluated by the selling dealer and an independent repair facility and is being taken to an authorized Buick dealership for further diagnosis. The vehicle is available for inspection.

Traction stabilization light comes on very frequently and vehicle loses power, step on gas and it sputters can’t get out of any one’s way, they throw parts at it and never fixes. From feedback off internet a big problem 2008-2017 Enclaves.

My car shutters and shakes when switching gear. My mechanic believes it’s transmission and or torque. My mechanic said he has fixed at least 6 of them recently as well and is very surprised there is no recall.

My car isn't leaking any oil so it is burning it and its it's under warranty still but they won't fix anything on it and other year and make models are having the same problem.

Driving vehicle would not get out of first gear. Decide to get vehicle home so I turned around and found that I did not have reserve also. On way back home transmission made a loud clunking sound and the check engine light came on. Was able to get home and park the car. Called tow truck to take to the dealers. This vehicle only has 23,773 miles on it. Dealer had to overhaul 3-5-r clutch housing.

I was driving with my family in our new 2016 Buick Enclave when I went to pass someone on a city street and the engine went into full acceleration. I put my foot on the brakes as hard as I could but it did not stop the vehicle. I had to put it into neutral and turn off the ignition and coast to the side of the road. Luckly there weren't many cars around me at the time. I was unable to get the vehicle started right away and I notified on star sos and they notified the police. It was towed to a Buick dealer where they are looking at it now. This was an extremely dangerous and frightening experience for me and my family.

When stopped on a incline and you step on brake the transmission will go out of gear ,then when you start off you have to hold brake till transmission engages, it is really scary , I have almost rolled back into another car several times . Went back to place we bought the car new , they said it must be a safety feature, it is not ! my wife is scared to even drive , love the car except for this !.
