The 2017 Buick Encore would blow out a large amount of white smoke and die in colder weather anytime you step off the gas pedal. It did re-start, however would die several time immediately until it stop smoking. Once it hesitated at highway speed when I let off the gas due to traffic and almost died. The dealership stated that the car computer showed no problems and nothing could be done. They admitted it should have recorded the problem I had, but did not. But the computer was still trustworthy to advise if the car had a problem. I has two near collisions due to the care problems just a few weeks prior to taking it in. I was advised that it was not possible to obtain a print out of the what the inspected because it was in the computer and non-printable. I feel the vehicle is unsafe to car, not knowing if the engine will just stop, and not able to find out why it stop in the beginning. The dealership advised I may need to wait till nest winter to check it again. The fact it almost cause an accident was not important.

This vehicle has a keyless ignition system. Twice my wife accidentally turned off the vehicle, once at a stop, the other time on a freeway at 70 mph. She was unaware the vehicle could be started in neutral thinking she needed to be in park. The vehicle continued coasting allowing her to move to the side of the freeway. There she was able to put the vehicle in park, press on the brake and restart the car. She did not realize the vehicle engine was off until she.pressed on the gas to maintain speed. She panicked and turned to me as an engineer with 40 years in the automotive industry. I kept her calm and instructed her what to do. Only when we were on the side of the road did we determine she had accidentally turned off the engine when tuning the radio. With no warning or indication the engine was off the results could have been catastrophic. Her colleague at work also did this in his Lexus. The proximity of the start\stop button to other similar controls appears to be a factor in these incidents. No warning from the vehicle not notice from the manufacturer of the sales dealership of this possibility and what to do does not prepare the driver for when this occu.

5 month after I had bought the car I was going 35 mph down a regular street when the car stop then when I want to move again the accelerator but then the car came to a complete stop where the engine had smoke coming out of it. The dealer said that there was a big hole in the engine. After they repair it no more than two weeks later I was going down a road where the car just turned off and it did not even let me move out of the road way. And now 3 weeks ago I was going down a street going 45 mph when the person in front of me stopped all of a sudden and I hit my brake so hard but they had not responded which led me to crash in front of the person in front of me. Luckily neither of us were injured but now for sure I know I do not feel safe driving any of General Motors cars whether is be Buick or GMC.

Aprx 6am Tuesday July 18, 2017, aprx 5:45 am, with no key fob in my wife's or my possession and no one within 30 feet of the care parked in the garage, the 2017 Buick Encore started on its own. The car was stationary and parked in the garage since aprx 7:00 pm Monday evening the 17th. Hearing a noise in the garage, I went there and found the card engine running. The garage door was closed, and no one could have entered the garage. We are taking the car to place of purchase, klick lewis Buick chev, palmyra, pa to determine what they will do to correct the problem. Checked recall and found nothing. Since this self starting could possibly cause other damage including carbon monoxide in a closed area (don't know if it would have shut off after a set short time on its own) thought it should be reported and a notice sent out to all Encore owners warning them of this issue.
