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.

During a rainstorm water is entering the fuse box under the glove box and the carpet and padding underneath is soaking wet on the right front floor. When the fuse case was opened water started to drip out. The engine continues to run with the key off and the only way to stop it is to pull the ignition fuse under the hood. Unfortunately the battery died by morning and I could not get it charged for a few days. Now I have learned how to take the battery cover off which is located in the back of the car and remove the plastic covers under the mat so I can disconnect the battery so it doesn't run down. The rear wiper will not shut off now since this started. I am a 75 yr old widow and wonder how this problem has not been on a recall. It causes a very dangerous situation. I will try to see if I can get it into a Buick dealer this week and pray god it doesn't cost me an arm and leg to repair it. There are service bulletins on this problem and seems to be quite freqent yet I have not received any notifications from you. If this happens at night in a parking lot what am I to do? can the car catch on fire by not shutting off?.

The contact owns a 2016 Buick Enclave. The contact stated that while accelerating from a complete stop uphill, with his children in the middle rear passenger’s seats, the vehicle stalled. The check engine warning light illuminated. The contact shifted to neutral and allowed the vehicle to roll downhill to the side of the road. The contact turned off the vehicle for 10 minutes. The contact restarted the vehicle and was able to continue to drive to his destination; however, the failure reoccurred that night, upon accelerating uphill from a complete stop. The local dealer and the manufacturer were not notified of the failure. The vehicle was not diagnosed nor repaired. The failure mileage was approximately 118,949.

My car was repaired by a dealership in texas. First they said it was a fuel injector. They replaced that. Then they said that that didn't work so they said I had a cracked head. They replaced that. I brought it home to shreveport, la. And it had gas fumes coming of of the a/c vents. The dealership here in bossier city that they put in a broken part. They supposedly fixed the problem. I picked the car up and it still had gas fumes. I took it back. They smelled it. Kept it for 2 days. They couldn't find the problem so the kept driving it and running it until they couldn't smell it any longer. I picked it up again and I still smell it. I brought it back but they are denying that they do. Even lied to gm customer service that they rode around with me. I had a horrible headache when I returned home with the car. It's been parked for over a week. I am terrified to drive it scared it will catch on fire or my children and I will get sick. Please help me. I have tried working with gm but they are no help. They give me the run around. The mechanics have also lied so many times regarding my car to gm customer service. I need someone in my corner. I haven't been able the drive my car sine 5/16/2019. It went to the 1st dealership on 5/18/2019. I drove about a total of 1. 5 since.

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.
