Yellow 2000

Took the Vette out for a short drive today, 2013 with 300 miles. First the HVAC display started flashing. Drove to the dealer and made an appointment to take it in in the morning. We stopped for lunch and when I restarted it the light had stopped flashing, but it was iding really rough and then the check engine light came on along with the Service Traction Control light. Anyone else had this problem?

There are hundreds of threads regarding this and the causes are varied. You should take it back to the Stealership and leave it with them with the engine running when this message occurs. They will hook up the Tech2 and figure out what is going on. If you shut the engine off, the condition will probably go away and they might not find any codes.

Thanks!! I was already at home and shut it off. When I restarted the problem was still there. I have an appointment with service in the morning.

I had the issue twice with my '11 GS. First time dealer said the #4 plug wire fell out of the coil. Second time I looked and the #4 plug wire was broken and hanging, dealer ordered a new wire. I'd say pull the covers off the engine and at least take a look for yourself, it may save a trip to the dealer.

Byron, you were right. It was a broken plug wire. Strange on a car with less than 400 miles. The flashing HVAC display was replaced. The service visit to Jon Hall Chevrolet in Daytona Beach was probably the best I have ever experienced. The service advisor, Katie was wonderful.

Glad to hear it was a simple fix and you're back on the road.

There have been more than a few of us with the same issue. Since this problem seems to span multiple years I think Chevrolet needs to look closer at the construction or installation of their wires because either they are being produced with a defect or the installation is breaking them. In either case they seem to stay on the coils until vibration shakes them loose. Don't even get me started about on board computers that won't even tell you the correct problem.

I agree. There was another guy there today with a 2011 GS with the same problem. He said it had happened twice. There was another couple in the waiting room that overheard our conversation and he said they had a 1957 fuelie that he bought new.

Kelly, yes it is the local dealership that I have dealt with before. I bought the Vette there 2 months ago and took my daughter and son-in-law back a few days later and they bought a new Traverse. They are great to deal with.
