“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. …”

“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 took my car in for routine maintenance service and requested them to investigate a rattle noise when the car is started and when it idles. The vehicle was around 96K mile range. The repair center said it was the fuel injection system and it was normal. Fast forward to now, I have 111k miles, same rattle noise, and took my car back to shop for routine maintenance service and investigation into the rattle noise. It's the timing chain. …”
