Tonight my check engine light came on...but it was after I had to get a jumpstart because somehow my autolights turned off and they stayed on. Anyways its running fine and all but the CEL is on. I have OnStar and I called them and they ran the GM remote diagnostics test and it was something along the lines of drivetrain memory malfunction or something like that. Said something about a possible loss of power from the drivetrain and needs to be serviced at the dealer ASAP. Now I beleive some other owners on here had a very similar problem. For those of you who had the problem was it something that just needed to be reset or what? I hope this isn't something major. Shouldn't be cause it only came on after it was jumpstarted.
