2022 Buick Encore GX problems

Filed Oct 22, 2026 · Electrical, Engine · MA

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 in congested city traffic and on busy roadways. Sudden loss of power can leave the vehicle stranded in traffic, prevent safe maneuvering, and increase the risk of a collision. The dealership has repeatedly inspected and attempted to repair the vehicle, including replacing the transmission, but the problem continues. I have also submitted a complaint with GMC. I request that the federal safety agency investigate whether this recurring failure represents a safety-related defect affecting this vehicle or other vehicles of the same make and model.

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.

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 federal safety agency Hotline to report the failure. The failure mileage was approximately 28,586.

Car began giving an alert that said "shift to park" when vehicle was clearly in park but car would not shut off. I called buick customer service, they said to take it to a dealership & have the problem confirmed with the service dept. & they would open a case for me. (they did not tell me not to have it fixed). I knew there was a class action lawsuit regarding this issue, yet no recall as of yet. The dealership confirmed the problem (as listed in the lawsuit). I had to pay $503 after they gave me a $100 goodwill discount. I called buick back to explain that I had the car fixed at my expense (I had no choice-the car would not shut off) & asked how to go about being reimbursed for a known issue with the car. I was told that since the dealership gave me a discount that there was nothing else that can be done. I asked about opening a case & was told that since my car was fixed, there is no case to open. I have asked to have my call escalated to a supervisor & am still waiting on a return call. I have to assume that since there is no recall, the shifter was replaced with one that will most likely fail again. This is unacceptable. I have had the car for one year. A recall should be issued for the park shifter failure. And I should be reimbursed for having to pay for it.

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 added every time I start the car in order for it to work for maps or phone calls.

The vehicle has less than 60,000 miles. Sometimes, when it is shifted into park, the info center states that it is not in park. I have to jiggle the shift or shift it into other gears and go back to park. The shift is definitely in park when this happens.

I have a 2022 Buick Encore GX with 34,200 miles and I put my car in park but the dashboard said Shift to Park. I tried several times to put it in park but it wouldn't recognize it was in park. The car also wouldn't cut off. I reversed and went forward and back several times trying to put it in park, but it wouldn't see it was in park. I called the dealership and they said jam the gear shifter really hard forward and it would recognize it until they could see the car. The only appointments they had were 2 weeks away. I can't use my car for 2 weeks. That isn't right. It shouldn't have done this at 34,200 miles! Also if the computer doesn't think it's in park then it could roll and hit and injure a child, another car, people etc. GM/Chevorolet shouldn't build cars with known problems. This is a serious Safety issue. The car isn't safe.

1. What component or system failed or malfunctioned, and is it available for inspection upon request? Answer: I only have 34,200 miles on my 2022 Buick Encore GX and when I put my car in park, I get a warning message on the dashboard telling me "Shift to Park" but I am already in park and my car won't shut off. Why at 34,000 miles? 2. How was your safety or the safety of others put at risk? Answer: What if the car thinks it isn't in Park and starts rolling hitting a child, another car, or building? 3.Has the problem been reproduced or confirmed by a dealer or independent service center?

The bolts connecting sections of the exhaust system broke off at 18 months. The bolts are not separate pieces. they are part of one side of the exhaust so you have to replace an entire section the the exhaust
