The PVC valve was frozen and leaked oil everywhere. I was told by a mechanic at my dealership that it is a known issue. They want $3000 to install a heater unit.

Have had the car in the Buick dealership numerous times to get these things fixed. Each time was told it was fixed and I paid for parts and labor. 1. Engine Light keeps coming on. 2. traction light keeps coming on. 3. Power steering goes out 4. Press on gas and have to floor it in order to just crawl to a place to stop. 5 Hard jumps after stopping at a light Have had this in to Tasca Buick and each time they say they fixed it - then it happens less then 2 weeks later. Have told them this car is going to kill someone with the steering going out while driving. I have a 2015 beautiful Buick Encore in the drive that I cannot drive. I am 77 years old and can't just walk. I don't know what to do. I have tried taking it in to have it fixed and it keeps doing the same things. It is definitely available for inspection. This has happened numerous times since I have had the car. Not just on one date - numerous dates

While driving, I received a call that routed through the Bluetooth hands-free system. Within seconds of receiving the call, the entire system seemed to blitz out and shut the car off completely. Luckily I was not going fast and was able to glide to the side. I lost almost all the ability to control the car. If this had been on the freeway it wouldn't have ended as well.

I purchased this vehicle in 2017 with only 45,000 miles, 1 year warranty was purchased. I have had constant issues with tires, but more seriously I have had over $2000 in repairs for intake manifold, air conditioning, various issues with tires, repaired thermostat. I had an ignition problem repaired in 2019 and now the check engine light keeps flashing, the motor doesn't want to engage and I am in fear for my life that I will be on the highway and it will just shut down, causing a collision!

Tried to stop before a red sign on a city street, the car accelerated on its own, passed the red light and run at about 60 mph on a 35 mph street for about half a mile and then stopped by itself. Pressing the brakes and even putting it on park did not help. I am lucky to be alive with my two passengers, and lucky not to kill anybody or cause property damage.

There is a constant coolant leak appears to be coming from the turbo area. Coolant smell is constant as the coolant is being burned off by exhaust manifold. Loss of cooland can lead to overheating and engine failure.

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.
