Car has 4 trips on rollback and one driving in for transmission problems 3 trips was when coming to a stop the car will will slide to stop almost making us hit dash of car each time there would be a warning about a minute before service transmission. One of the Trip for transmission service light I did drive it in. The car went in yesterday for transmission service again. My thinking of this is what would happen if I were driving 70 MPH and the car locked up what would happen to me and the people around me.

At a full stop, the engine auto stop shuts the entire vehicle down. Vehicle must be re-started and all features like radio, clock etc. Return to the factory settings as if the battery had been disconnected. Once this happens, I've notice the engine auto stop does not work for an extended period of time. The vehicle is a 2017 model with only 17,000 miles. At 9,000 miles the water pump had to be replaced.

All 4 windows in the vehicle go down when the driver and key fob are no where near the car. Only 1 time has this happened while the driver and key fob have been in the car and the driver was not touching the fob. In this case the driver put up the windows, opened the door, during which the windows went back down. All other instances the windows went down in various locations with no commonality (my parent's house while we went shopping, the gym, walmart.) this has occurred I believe 6 times over 3 months. The vehicle was purchased April 2017 and has under 11,000 miles. Twice this has occurred and during or immediately following a rainstorm. Once causing extremely soaked seats and I don't know how the inside electronics, such as radio and gps were not ruined. The first time my car was loaded with over $500 in toys and thankfully none stolen.

On November 19, 2016, I purchased the 2017 Buick Lacrosse premium AWD. On that same day, while I was driving on the highway the overheated engine light came on, beeping sound, oil light came on, shortly vehicle indicated immediately to stop, which I did, stranded on the highway in en route to dealership. I had just left the dealership approximately five minutes ago after I purchased the vehicle. The vehicle was towed to dealership. Simultaneously at 4:48 P.M. est, onstar sent notification via email stating, "a critical issue with the engine and transmission system in your 2017 Buick Lacrosse AWD has been detected...please service your vehicle immediately." On November 20, 2016, I rescinded my contract with dealership connected to the above issues. On November 21, 2016, dealership fully refunded $47,848.19 and continued its possession of said vehicle since November 19, 2016. On September 10, 2016, I ordered the vehicle with the dealership with high expectations on a new vehicle. The dealership did not disclose to me about the above problems and safety issues prior to my purchase. I felt unsafe in the vehicle because it was making loud noises underneath the car as I drove it, for example, I felt like I was going to blow up in the vehicle. I also felt unsafe driving at low speed with the emergency lights on the highway. I felt unsafe stranded on the highway in the vehicle, waiting for the tow truck.
