Consumer Description

Driving home from work and was about 4 miles away from home when the "service stabilitrak' and "reduced engine power" lights came on. Safely drove home, parked vehicle on road to shovel driveway (snow storm). When I went to start it to move it into driveway "oil pressure" light came on. After moving it off street noticed oil on road where vehicle was sitting. Had towed to dealer where I get my oil changed (which was done about 3 weeks prior) they stated rear main seal went causing oil to drain from engine which also ruined my valves and threw out the timing. GM says they'll pay 25% of total $6200 bill. Although GM has yet to return a call regarding the case I opened with them on this asking for a larger percentage.
