I have a 07 tahoe LTZ that we bought in april of 06 and since that time I have had alot of problems with all of the things the nav system runs and all the gages on the console and even the door dinger shutting completely off. It started a couple of months after I bought it. It never happens while I am going down the road just when I start it up. It is like the whole electrical system in the front console is just off. Nothing works. If I turn the key off and turn it back on sometimes that will fix it, however on one of our hottest days last week (104)nothing worked including the air conditioner. Had to wait about 30 minutes for it to work and come back on. I have taken it back in to the dealership once when it actually happened, but for that one time they keep telling me that they can't get it to replicate and therefore don't know what is wrong with it and cannot find a solution. This last time they said that they had called the chevy corp. and that no one else has had any of these problems. So I think thats really what I want to know is if anyone else out there has had this particular problem or anything close to it and if you have found any solution to the problem. I would appreciate any feedback that you give me. Thanks.
