The lane assists and cruise control does not work and the GM dealership here in Southern Pines, NC can't fix it. They are sending the car back on the street with a 19-year-old girl behind the wheel of a car with electrical issues.

My car was parked in the driveway, and it was locked. The keys were in a bowl next to the door. During the night the sunroof opened with no contact from anyone and it rained that night and flooded the inside of the car. We did research on the issue and this has happened to many Buick owners. I put the car under shelter and got out as much water as I could. The sunroof would not operate to close it. First thing Monday morning I was at the dealers. The dealer stated that had never seen that problem. I gave them some of the information I found on the internet. They could not get the sunroof to close. They ordered the parts and kept the car to continue drying it out. Once the parts arrived and were installed they got the sunroof to close but then it opened about half way. They are talking to Buick engineers. Luckily this happened while my car was parked. However, had I been driving and rain started poring into the car it could easily cause an accident. It would be a serious distraction to the driver in addition to the steering wheel becoming slick with water and hard to handle. Also it could cause other electrical components to fail due water in their system and cause an accident. I believe this is an electrical manufacturing defect and needs to be addressed. Currently my car is still at the dealer.
Buick Envision 2016 Mileage - 58315 One owner The car has had three events over the last year where it would not start. After the car is driven for awhile and after it's parked and turned off, it will not start. Everything in the car will function (windows, radio, door locks) but there seems to be a disconnect between the key-fob and the device that communicates with it. There is never a warning light or other indication this is about to happen. We tried to jump the car but it has no effect. If we wait twenty to forty minutes it will start on its own. On the third failure, we had the car towed to the dealership where it was purchased. When the car was unloaded from the tow truck it started. The dealership service department ran diagnostics but the error codes were not helpful. They kept the car for ten days and could not duplicate the error.

STOPPED, TURN CAR OFF AND RESTARTED STILL DID NOT TURN BACK ON DASH BOARD OR AND RADIO/ NAVIGATION SCREEN. WAITED TILL NEXT DAY TRIED AGAIN STILL NOT SUCCESSFUL BOTH SCREEN COMPLETELY BLACK.
