Our 2015 Buick Encore broke down on 9/12 while driving home late at night traveling over the cuesta grade we had a tough time with acceleration and had to drive slow over the grade and on the highway all the way home. Our car was barley moving as we made drove it into our driveway. We had lost all acceleration. Our car was towed to the dealership on 9/13. We were told we were "just over the warranty mileage allowed 70,000 and had to pay for the repair. We asked GM to contribute since we were barley over the warranty mileage allowed".we picked up our car after the original turbo was replaced on 9/23 and again the car began making noises on the cuesta grade. Again we started to lose the ability to accelerate and had to drive the highway at a low speed to make it home with the car making terrible sounds and noises. This second turbo had failed. We had the car towed back to the same dealership on 9/24. After about a week the dealership called and explained they had installed another turbo which had failed again and they were waiting on parts to replace it which would be the 3rd turbo to be installed in our car besides the original one the manufacturer installed. Each time the dealership stated additional things were happening to the car when the turbo was "going out".we received a call on 10 /9 (over two weeks from the time the car was towed to the dealership) that the turbo was now repaired and we could pick up the car. We are very concerned for our safety with this car. When the turbo goes out it can cause a wreak since we have to travel on the highway and cuesta grade as we lose ability to accelerate.

My engine has been misfiring and Buick refuses to fix the problem. It is unsafe to drive, jerking, and getting stuck in first and second gear when trying to accelerate. I have brought it in twice to have it fixed with proof that the engine malfunction light is on, and they said there is nothing wrong. I emailed the manager in service, and he said there is nothing he can do.

I was driving on a highway at 65mph. On a straight portion of the road the engine light came on, the engine revved up to over 4000 RPM, the power steering locked up, and many other lights came on on the dashboard display. This was a very dangerous situation trying to control the car. I was forced to slow down and when I reached 40mph the power steering came back on. The engine was still running over 4000 RPM. Most of the dashboard display lights went off except for the check engine light. Had to drive under 40 mph until I got home. While this was happening my onstar sent me a notification that there was something wrong with my transmission. The car was then towed to the GM dealer. At the GM dealer they could find nothing wrong.there were no error codes in the cars computer.

Had an oil change at dealer (typical 15,000 mile check). On the return trip to home, engine started to miss, smoke was coming from back of car like oil was being burned and the engine "check engine light" came on and the car was stopped. Called dealer who had car towed to their location. While waiting for tow, I checked oil level (it was over filled by at least a quart (maybe more), dip stick was not seated properly to check oil level. When the tow truck drive arrived and hooked the car up to tow, he indicated that the passenger side bolt that holds the engine to the frame was missing. He indicated that he would tell the dealer (colman Buick) about the problem. Later on the second day at the dealer, they said they were working on the car all day and were in process of replacing all fuel injector (don't know how they could go bad in 13K miles) and the smoking of the car has been reduced (somehow oil is getting past the rings and is being burned.two days and still no car.

Driving along at approx. 55 mph on a main hiway slowed to approx. 40 mph to make a turn, when suddenly the engine stopped operating. Everything shut down, no steering, no brakes. On star did not respond, car was disabled about 5-7 minutes, tried to start several time with the key. Serious issue, had car towed to dealer, found nothing wrong and no codes were obtained from the computer system!
