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.
