2022 Buick Encore GX problems

“At 15,000 miles the check engine light came on while going to a store. At the store, the vehicle was put in park and tried to shut off engine. The dash said "shift to park". Took to the dealer, was told sensor went out on transmission. They said it was the electronic controle module. They didn't think that was part of the drive train warranty. When I looked online I found many other Buick owners complained of same issue. Posting online that they are slamming shifter into park up to 20 times to get sensor to register that it is in park so they can shut vehicle off. I feel it is a known buick problem and gm doesn't know how to fix so they won't issue recall. If you can't shut the vehicle off, the engine could over heat, not to mention run out of gas. And if people are slamming the shifter in and out of park to get vehicle to shut off an accident could occur in a parking lot or street if the sensor cannot read the shifters position properly. What if the sensor senses improperly on the freeway, is my vehicle going to come to a sudden stop on the freeway? General motors has let this gone on too long.”

“I am reporting a recurring safety issue involving unexpected stalling and loss of propulsion in a 2022 Buick Encore GX. In February 2026, the dealership replaced the vehicle's transmission with a rebuilt transmission. Since then, the vehicle has continued to experience sporadic stalling and drivability failures over the past eight months. It has been brought to the dealership at least six times since February for inspection and repair. Despite these efforts, the problem continues. Most recently, on October 20, 2026, the vehicle unexpectedly stalled while my husband was driving in downtown Boston. It had to be towed to an impound facility and, after retrieval, was towed to the dealership, where it currently remains available for inspection. There were no symptoms and no warning lights prior to the incident outside of the months of similar sporadic incidents. The vehicle has spent more than 25 business days at the dealership since February. Despite the rebuilt transmission replacement and repeated repair attempts, the stalling issue remains unresolved. It goes without saying that unexpected stalling and loss of propulsion pose a serious safety risk, particularly…”

“6/4/26 Took to dealer and stated that the check engine light was on and car was running sluggish. Had stopped at Autozone and their scan showed the code P0102. The dealer charged me 259.00 to do a diagnostic showing the same thing. 6/26/26 Back to the dealer with the same problem and now they stated they replaced the Compressor Air Intake Turbocharger and Install Vacuum Tank Kit. I had the vehicle back for few days and while I was driving, the lights came back on and the car went from 58 to 23 mph within seconds. I would have gotten hit if I was on a major interstate. 6/30/26 Had to have the vehicle towed in because at this point it would not start at all. They stated that the code for mass air flow and lean condition. Replaced mass air flow sencor. On the second invoice along with telling them before, I had also told them about the car when I would try to put in park to shut off, it would ding and light would say..shift to park. I have to turn it back on and mess with the shifter to get to shut off. Stated it would cost me 800.00 which I cannot pay at this time. Another issue that I have had since I bought the vehicle is that my phone has to be deleted and…”

“The contact owns a 2022 Buick Encore. The contact stated that while driving at an undisclosed speed, the emissions warning light illuminated and hot air was coming from the A/C unit, despite the A/C cooling setting being activated. The vehicle was taken to a dealer, where it was diagnosed that the purge pump and an unknown part needed to be replaced, and loose bolts in the A/C caused Freon to leak. The vehicle was repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline to report the failure. The failure mileage was approximately 28,586.”

“We where lucky compared to the other lady who wrote in this problem area. We where parked in a parking lot, ran in store to get item, left car running for wife to listen to radio and stay warm. As I got in, we spoke and was ready to pull out of the parking space and the car went weird. The car hesitated a little but was still running and then all the warning lights came on. It told us on the screen that steering might be effected and engine will not run to full capacity. The car ran like it was in "limp" mode(like the Kawasaki ATV when they have issue). We made it home carefully and slowly. We called and dealership had the car picked up. It's been there over a week now, their computer hook up said it was the fuel pump and also a fuel line was needed, they are waiting for the parts to come in. We have leased the standard Encore's before this GX and we never had this issue with them other 4 cars. They have been a great car, we are in hope that this is not going to become a major issue for the GX series. We made it only 9K miles when this happened. We where thinking of buying it when the lease was up, not sure where our thoughts are now. If this is a bad batch of…”
