While driving home last night, all of the warning lights on my instrument panel lit up, the engine tried to stall and eventually locked up the brakes for a second or two. I've only had the truck for a couple of months and it was bought new. Called onstar and they did two diagnostic tests which didn't reveal a thing. They seem to think it went into reduced power mode but aren't able to tell me why. Everything went back to normal but then the stabilitrak warning light came on telling me to service that. When i got off of the highway that too went away. So, does anyone know what the heck could be wrong? I have an appt with the dealer in the morning.
Sorry,no idea what it could be.Hopefully the dealer can diagnose the problem.I don't like the idea of the brakes locking up.Please keep us posted as to the outcome.
Well, I sure hope it's something simple. I'll update tomorrow.
