2014 Buick Enclave engine problems

Filed Jul 10, 2026 · Engine, Fuel system · VA

The engine, power steering, stabilitrak, and reduced engine power (vehicle would essentially die while driving at random times). My safety AND others were put at risk when I am traveling down the road/interstate and the engine just cuts out and am no longer able to accelerate to any speeds, causing me to have to pull over to the shoulder WITHOUT ANY ENGINE POWER. Yes, the problem has reproduced and confirmed with the dealer I purchased from. Vehicle has not been inspected by the above mentioned. Only had it inspected by the dealer I purchased the vehicle from. There were no prior lamps, messages, or other symptoms until it just showed up while driving one day. It happens at the same time as the engine loses power and acceleration. The check engine light comes on, within 2-3 seconds the engine "dies" and then the "Service stabilitrak" pops up, as well as the warning "Reduced Engine Power". This first appeared on approximately on 05 JUN 2026. Vehicle was purchased on 12 MAY 2026.

I bought the vehicle in December 2020 from a dealership in Mason, Ohio named Borcherding Buick GMC. I asked, specifically to make sure the vehicle did not have any issues, especially transmission issues and for this to be researched, as well. I was not made aware of Bulletin No.: 18-NA-358, which affected Buick Enclave models from 2014-2017. I purchased the vehicle and sent a wire transfer for the purchase price to the dealership through my bank, USAA. We began experiencing transmission slips about a year into the ownership, and I had my mechanic look into the issue. He had just replaced the transmission on my wife’s 2011 Dodge Grand Caravan previously when it experienced a catastrophic failure and had to be replaced. This is the reason I asked to make sure the transmission on the 2014 Buick Enclave was working correctly and properly and there were no known issues. The mileage of the vehicle was under 60,000 miles at the time of purchase, so this should not have been an issue for the vehicle at all and the previous owner was, apparently, an elderly woman who had the vehicle serviced at the shop, but I cannot confirm this. The point being, there was a known issue with this vehicle that was not disclosed to me that General Motors was aware of and could have led to me not purchasing the vehicle. We needed an SUV to drive my wife and daughter(s) to and from volleyball tournaments and something that we did not have to worry about. The result is a replacement transmission paid for by me out of pocket by a GM dealership. GM refuses to acknowledge their faulty transmission. The rebuilt transmission is experiencing the same issues the old one was and GM wants me to take it in and have it “looked at”. The transmission is faulty! They know this and they refuse to reimburse my costs and refuse to acknowledge the dangers this transmission imposes to drivers and our families! Please investigate this transmission and their engineering.

In 2016, and again in 2020 after the dealer first fixed the issue, while driving at high speeds, on highways, also in the rain, again at a stop light, the vehicle suddenly decelerated, causing the potential for a very serious accident. The warnings then displayed on the dash included reduced engine power, service stabilitrak, service traction control, and traction control off. The vehicle only then drove at slow speeds, sputtered and jerked, and felt like it might stall. When able to pull over, at times turning off the car reversed the problem. Sometimes the check engine light was on, sometimes it wasn't. Sometimes it would drive fine and then out of nowhere, it would happen again. In 2016, the dealership had a difficult time finding the issue. After several days of driving it, they identified the problem as a fuse box issue and replaced the fuse box. This seemed to fix the issue until it happened again in 2020 while driving. On a road trip, it happened while on a highway, again at a red light, and while on a highway again. Each time, we pulled over, turned the car off for a while. One time in particular, the issue didn't go away after turning the car back on.
