2007 Tahoe complete electric/nav shutdown by treyj

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.

I have had similar issues with my 2007 LTZ that I purchased in July 2006. No radio, Nav, Back up sensors, Traction control, stabil trac, etc. But only at start up. Short term fix is shut the truck off and open the driver door to reset the retained power, (that was your 30 min delay) then re-start. This always works for me. Long term fix, after replacing the complete Nav/radio, body control module, Misc sensors, ignition switch, several module software downloads/updates, and 9 days in the shop was to repair a faulty connector on the back of the radio. Apparently the Data Buss runs through the radio/Nav and activates several other modules on start up, if the signal can’t get through the Nav/radio, you get these types of failures. GM originally blamed it on the Nav Override that I installed, but after removing the override the issue continued. 3 months now with out an issue. Hope this helps, PS. You should post this on the 2007 Tahoe board. George

2007 Suburban electridal problems by scatz76900

I have been having problems with my '07 Suburban. Multiple times I have started my car and my radio is on but there is no sound, my blinkers have no sound, passenger side map light has been out and rear console air doesn't work from the rear and isn't lit up. Today was completely different. I turned my Suburban on and realized I had radio but no XM satellite. I pushed a preset button and it said that there was a satellite communication error. I figured well maybe XM is experiencing some problems. I then realized later that I had no blinker sound. I got home turned my car off and the radio would not shut off. I even got out closed my door and the radio was still on. I got back in and started the car again. I heard a loud pop and the whole radio went dead. Again no blinker sound and absolutely no radio. The dealership is just up the road from me so I drove it there and the service tech (who knew we have have had electrical issues) said it sounded like a fuse. He came out to check the fuses, started the car and the radio was back as well as XM so it obviously wasn't a fuse. They can't seem to find the problem and actually contacted GM and was told there was a bulletin which they had fixed the last time I was in. I guess that wasn't the problem. I have also always noticed that when the navigation cd is installed it constantly makes noises even when the car is not on. Any suggestions out there?

Hate to sound mean, but buy a honda! My 04 pilot's nav has worked like a dream. So has everything else. I check this Tahoe forum because I want to get back to American iron,but we still can't build reliable cars. It gets so frustrating.

I can assure you that the Pilots have their problems too. Let's face it...nobody writes in to this forum because their vehicle is functioning properly. There are hundreds of thousands of Tahoes and Suburbans that run fine and are trouble free. I have one. Every manufacturer has their lemons. And those are the ones you hear about.

I have a 07 Tahoe Z71, purchased new Feb. 20, 2007. In March the radio, DVD player, rear parking assist and all the audio in the vehicle lost power at startup. The first few times it did it, when I would restart it would come back on. Then it just went dead completely, my dealer replaced the radio but it did it again then they replaced the ignition switch. It was okay until about 4 months later and it went completely dead again. They contacted GM and checked all the electrical connections but could not find a problem. They say they have not had any other problems like this. They don't know what is causing it, so they can't fix it. I have started arbritration with GM to try to get them to replace my vehicle. Hope you have better luck.

I have a 07 Suburban and I have the same problem. At start up the radio doesn't work sometimes. This morning while I had the problem I took it to the dealer, they took note of it and they will check it on monday, let's see what they find out.

Do you have parking assist and DVD player? If so, does it also go out?
