Massive coolant leak. Been happening on and off since I bought the car in nov2019. Taken to several shops and have had replacement done and it goes right back to leaking. This time the shop believes it's leaking into the engine itself.

It seems like the 2015 Buick Encores are having a lot of the same issues. I do not see a recall for any of these issues. 1. loss of power when trying to accelerate. This has almost caused an accident for me. I had plenty of time to pull out, but my car wouldn't speed up. Thankfully the car coming up noticed I was having issues and slowed down. This also may affect the performance and fuel efficiency of the vehicle. No warning lights came on. It eventually corrected itself and I was able to accelerate. This has been an ongoing issue. Nobody seems to know what is causing this or how to fix it. 2. I start my car and put it into gear, and it shakes like it wants to stall. I quickly put it back into park and wait a few minutes before putting it back into gear. It also does this while I am waiting at lights at intersections. That is very concerning because if i stall mid intersection this could cause and accident and or injury to me or other motorists. No lights appear when this happens. Again, nobody knows why it does this or how to correct it. 3. Back of my car stared chipping paint for no reason. There was no trauma to cause this to occur. Apparently, this is another common issue with this car. I've read that there have been lawsuits against the company for using paint similar to what this is doing. 3. I had to replace my engine under two years of having it. It was still under warranty at the time, but I hadn't had the car very long at all.

The turbocharger on my car is failing and had a verified check engine light code PO299. The car is a 2015 with low miles, only 53k. This is an obvious manufacturer defect/defective product with an estimated cost of $1500 to replace, according to an ASE independent auto shop I use for all my vehicles. The car is unfortunately not under any warranty anymore, to my knowledge. There is no recall on this part but online on Buick forums and other credible sites, you will find owners of the same exact car reporting independently, the same failing part issues. I am the second owner of this car and bought it used in 2021 from Carmax. Since then, I have spent $$$ to fix random necessary repairs that are defects of the car but not on recall. Recently, the ac went out and that was over $500 alone. Prior to that an 02 sensor and sparkplug went out, etc. I want GM to reimburse me for the repair cost of the failing turbocharger on this low mileage vehicle as it is without a doubt, a manufacturer defect needing repair to prevent the engine from failure and a total loss! I contacted a GM/Buick agent and formal complaint and request for reimbursement. I am now waiting for up to two days for a "senior agent, " to contact me back and discuss further options, if any. Until then, I am without a car with two kids at home and this defect is unsafe and a financial burden to me and my family. This is a known issue on this vehicle model and should be covered under a recall from GM!

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.
