The check engine light has come on for the first time and Onstar said to get the vehicle to the dealer immediately. My wife is on the way now. Will the dealer give us a hard time about the addons I have done: Borla exhaust, Rancho Lift, K&N filter? We only have about 20,000 miles on the H3. If they have to keep it overnight should we expect a free courtesy vehicle?

 

No and yes

 

Thank you sir

 

Good luck and let us know what the problem was...

FYI..The Magnuson Moss Act is about add ons and aftermarket equipment and protects you from the dealer declining service because of such items

 

Should it turn out tobe the head replacement issue, please be sure to vote in the poll at the top of the threads here and read threads about this issue...good luck and hope it isn't anything serious.

 

Did you notice if the engine was idling rough?

 

Did onstar contact you immediately?

 

I would like to know that answer to.

 

No, they did not. When my wife called and said it came on I told her to call them. Onstar directed her to a dealer that was not even authorized to work on Hummers. She wasn't happy. She did not notice any difference in the way it ran. When she got up this morning to take it to the dealer the engine light did not come on. Onstar told us that it could be 30 different things wrong with it. They were no help at all.

 

Where's HG with his ODB-II scanner when you need him .. Hopefully you're not having the infamous head issue .. good luck and hope things work out!
