Buick Encore overheating problems

Filed Aug 2, 2026 · Engine, Fuel system · NC

Not long after I purchased my car, i noticed it was lacking power during takeoff and when driving uphill which forced my car to hit very high RPMs during normal use. There was also a P0299 code that appeared then disappeared frequently. I discovered a turbo special coverage N232395330 and took it to Williams GMC in Charlotte. After i told them very clearly what happened MULTIPLE times, confirming the underboost and the code, I even brought it in with the code, they told me the code wasnt "active" and that there no problems...even after i told them I didnt feel safe and couldnt pull out at intersections with fear of being rear-ended. I had videos, they refused to look at and told me to come back when the code was permanent. I drove the vehicle for the next year, 20k miles in order to get the code permanent, after a trip home, through the mountains, really tough without the turbo, my car was consistently pinging 4-5000 RPM under the speed limit on inclines...this happened every time I drove through, but this time the code was active the entire time. 2-3000 miles with the code, finally it was permanent. I brought the car back to Williams GMC, to get the turbo changed. I updated them on recent occurrences, flashing check engine light, the code active for 2-3k miles, and they performed a road test, and declared it wasn't a problem. I told them i recently spent 5k on repairing my cooling and AC system because the turbo, they said that wouldn't affect those components, meanwhile i know they have plastic parts that can melt and the engine being forced to push 4-5k RPM the extra heat could easily melt those parts. They said, nothing was wrong and the road test was good. sent me on my way. I called corporate, they told me to get a second opinion. I did [XXX] found the problem and changed the turbo per the special coverage N232395330. a week later, my engine overheated, i pulled over and it wouldnt start, engin won't hold compression.

•On January 25th 2025 I paid approximately $3,383 for a turbocharger repair on my 2019 Buick Encore. This included a turbocharger oil return tube, turbocharger oil supply and re, intercooler, int. man. & vAL. COV. Kit, R&R inter cooler, R&R turbocharger, R&R intake manifold, and turbocharger assembly. Since that time, the same problem has recurred and I have returned the vehicle to the same location on four separate occasions without resolution. It is currently available for inspection. •August 11th, 2025: Vehicle stalled in the middle of an intersection as I attempted to accelerate from a stop sign, placing me in immediate danger of collision. •I have had the check engine code read by another independent service center. •No one else has inspected the vehicle •The check engine light has come off and on since January when the problem began after visiting Mavis Discount Tire in sinking spring for a routine oil change. There were no symptoms prior to this first failure that signaled the issue that resulted in the repair. Prior to the incident on August 11th there had been repeated symptoms of an issue even when the check engine light was off. These issues included overheating, smoking, lack of acceleration, and stalling.

The car experienced issues with the fan turning off when car was turned off. It caused the battery to die. The car was serviced at the dealership and the tech found that the fuse block overheated and melted, causing poor electrical connections. They replaced the damaged parts and repaired the wiring. This still did not explain the fan not turning off and after the fuse block repair, the cooling fan was still sticking on. After pushing the dealership to further look into the issue the mechanic determined the issue was inside the fan assembly (it was assembled in the wrong direction), so they replaced the cooling fan. The dealership stated that this was a manufacturing error. They said this could have caused an engine fire and there was absolutely no warnings - just a fan that was stuck on. This could have put me and my new baby at risk for an engine fire and could cause issue for other owners if there were more assembly errors. The car is available for inspection if needed. It was only inspected by technicians at the dealership.

First the car started to act odd, jumpy or you could tell there was issues with the turbo. On [XXX] car overheated??? Out of nowhere. Mileage 82049. No warnings, no lights. We had it towed to shop where we were told we need new turbo, new engine, power steering service, ac service. The total Cost was $6813.54. We had to take out 2 loans - 90 days same as cash then 145% interest as well as pay $243.54 in Cash. We were guaranteed the car was in great condition. We picked it up on 1/24/25. Then on [XXX] - Odometer reading 82509 - We pulled over on the side of the road to grab something from the trunk. Driver got back in car and all of a sudden the car just shut down saying overheated and smoke was coming out of the hood. Again, Absolutely no warning, no lights, no weird noises, nothing! We are now stuck in the middle of nowhere with our [XXX] granddaughter. Thank God a police man drove by. The next day we had to have it towed back to shop. Once back to the shop we were told that the engine or labor that they just put in our vehicle would not be covered by warranty. Nothing was fixed!!! I contacted the attorney general. We went to pick it up on 3/28/2025. Once they got involved the shop agreed to do all repairs for $1873.96. (pay $600 now and then post date 2 more checks). The owners said they looked over everything and nothing should be going wrong. It should be good as new. On [XXX] We were on our way to Puerto Penasco Mexico where we have a vacation home. About 20 miles into Mexico the car just stopped. Tons of Smoke from the tail pipe, Low oil pressure all of a sudden came on. I am attaching pics showing that the car was not showing overheated. So now my husband and i are stuck on the side of the road in Mexico with no cell phone service with a [XXX] car that we can not get fixed no matter how much money or time we put into it. When we finally got ahold of the shop they said they are washing their hands of it and do not want to see this car again. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT
