While driving my 2015 Enclave the vehicle jerks and the engine light comes on. Then starts rattling and steering wheel locks and my speed reduces to 40, 25 then 10-5 miles per hour, the warnings read engine power reduced, traction control off, service stabillitrak. I pull my car on the side of the street, wait a few minutes and sometimes turn on my car and rattles again. Need to wait a few more minutes and the starts, the engine light stays on for a few minutes, maybe couple hours or for a day and then clears up. I took it to my mechanic and no codes came up. My mechanic suggested to do a full service on my car which I did and still happening. This has happened several times, while I'm on highway or city streets.. very, very dangerous. The video and pictures provided are from March/02/20, but I have this problem since fall last year( is when I first took it to my mechanic and performed a full service, picture provided) and last time happened to me was June/15/2020.

May 11, 2011 I went to work and turned my car off only the car did not stop it continued to run without the key in the switch. I waited almost an hour and tried it again and it turned off. When I left work it cranked right up but when I got home, it would not turn off. I called onstar and they told me before I had it towed, I needed to disconnect the battery. I called a mechanic to come to my house and he disconnected alternator and battery and it continued to run. He then had to disconnect the cable on the power box under the hood before it would shut off. I called triple a to have it towed to abernathy chervelot and Buick in lincolnton, North Carolina.
