Remote start didnt work this morning and upon getting in, noted the CEL. Chatted with OnStar and they stated I dont need to be worried about it or take action...?
U0121 seems to be related to loss of communication with ABS module. Is this a "known" event and the CEL will "just go away" as OnStar seemed to lead onto...or shall I get to the dealership?
