I have a 2012 Grand Sport Convertible that started showing "SERVICE ELECTRICAL SYSTEM" messages on a regular basis at about two years old. I took the car into two different authorized dealers to get it fixed under warranty...multiple times (and I have the paperwork to prove it). The root cause of the problem has never been found, and now the car is out of warranty. I spoke to GM Customer Experience yesterday morning, and was passed up to a senior adviser. I was assuming that WORST CASE....GM would honor the repair of this specific issue until it was resolved. However, the message I'm getting is that "if the problem had been found and repaired...then the warranty would have been extended". But since the problem was never found, then I have no claim of a warranty repair. I received a call back today from GM Customer Experience, and they again confirmed that they will NOT cover the warranty and were only offering $100 credit towards the diagnosis. I was in shock when I heard that. Have others had a similar experience? My Vette is my one and only GM purchase, I'll never make that mistake again.

Never had that experience, but it sounds about right, they will do all they can to not have to spend a dime. Sucks man, sorry to hear how they are treating you!

I don't know where you live, but you should investigate Lemon Laws in your jurisdiction. In the meantime, keep going up the ladder at GM. Service Experience advisor is an entry level position at GM, and typically is filled by new hires that know nothing more than what the rules tell them to do. You need to get to someone who has the discretion to make a decision. Obviously what you are being told does not make sense, and is completely unacceptable.


Oh, and shame on you for not pressing the issue while it was still under warranty.
