Panama City

I'm late to this party but I wanted to add my GMC Denali Sierra to this list. I have experienced the no sound issue with my new $86,000 truck on several occasions (happens about every six engine starts). My truck is presently living at my dealership where I have taken it in for this problem three previous times. Every time they have told me they have repaired the no sound issue and it is working fine. The no sound issue has always returned. In fact the last time that I picked it up at the dealership after the issues was repaired, I started the truck to leave and there was no sound. Also I constantly get the dashboard "Service Driver Assist" message about every five times I start the engine. This issue has also brought my truck into the dealership on four occasions. The last time it was in for repair the service department told me the factory was working on a repair for this issue but presently they could not repair it. My truck has 3100 miles and I'll be starting the Lemon Law process very soon.
