#146 of 252 Dead Battery
Dec 30, 2010 (10:25 am)
I've owned my 2007 Chevy Tahoe since new and it has under 50k miles on it. I have drained the battery 3 times while using the radio with the vehicle off in under 20 minutes and chock it up to an undersized battery. In the last 3 weeks however, the battery has gone dead 4 times without using it. Three of the instances were found first thing in the morning and the last happened when we went out to dinner. We were in the restaurant about 2 hours and when we came out the battery was dead. We had an individual that was driving behind us tell us that our backup lights were on once, but I couldn't get it to repeat right after that. A few days ago, a family member told us the backup lights were on and the Tahoe was sitting in the driveway, turned off. The vehicle had to be started and shifted into gear before the lights went out. It went to the dealership yesterday and they found nothing. I know it has to be a stuck switch or relay, but the "Users Manual" does not have a wiring diagram. Any help would be appreciated.

Sorry, don't have any info for you on wiring....we have been lucky now since ours went back to dealership and they supposedly changed the battery cable out - we haven't come out to a dead battery in over 2 months now - this is first time since we've owned the car (also original owner's) that we have gone this long without a tow truck being called. I really can't believe that a battery cable was the culprit - since it started on day 1 of bringing the vehicle home. I think they know what the problem is, that they fixed it, and just don't want to say so because it's going to be a huge recall if they acknowledge it. I agree that it is probably a wiring issue. Wish you the best of luck. Somebody from GM will probably contact you via email.....
#149 of 252 Another 2007 with a bad battery
Jan 02, 2011 (7:02 pm)
I simply cannot believe that I have a bad battery after only 32K miles. I am the original owner of this 2007 Tahoe LTZ and have now had my battery jumped twice. AC Delco used to be the best on the block when it came to batteries, but now I would not give you 2 cents for one. I took my Tahoe to the dealership for oil change and tire rotation. They did a good inspection and told me that my battery was going out. I said really, I have not driven that much. Their response was that this happens sometimes and all I could do about it was replace the battery. After reading the posts on this site, you can bet that I won't be buying a battery from Chevy. I will be going to Sears for their Die Hard Battery. I have had great success with them and they last a very long time.
Chevy really needs to do something about these problems with the 2007 Tahoe LTZ. A $100 for the heated windshield washer disconnection is not the answer. Make it work, like the product was sold.

I own an 07 tahoe and have issues with battery, leaving radio on while cleaning interior or leaving key in ignition for 5 minutes battery is dead. I just googled issue and seems other people have same problem. Another issue is the hinges have rusted out and been replaced and are rusting again.

I sent an email to you (or what's listed in your profile) and hope to hear back from you as to what my options are for getting this fixed. I'm hoping GM realizes this is a major issue that borders on being very unsafe (stranded motorists, especially female like myself!).
Please see if my email made it to you and let me know what you think should be done!

I've experiencing the same challenges as everyone else here with my 2007 LTZ, and maybe this has been covered, but it seems to me that this may be as much of a software issue as it is a battery issue. Case in point, we continue to be cursed by the dead battery scenario after leaving a door open for 5-10 minutes. I mean seriously, you can't leave the rear hatch open to load it full of whatever it is you're wanting to carry without having a dead battery? Dare I digress. But that is where we are at. Just turned 40K miles, have had this issue into the dealership a few times already where it supposedly was "addressed" and the issue still continues. The reason I think it is software related it because after getting a jump start to revive it, I can immediately turn off the truck, and turn it back on. Now if it were a dead battery, with all of the systems running, and less than 10 seconds of recharge time, there is no way the battery would start the vehicle. So I am starting to think that the computer software has a fail-over circuit that is supposed to protect the battery from being drained from all of the systems that run (like the NAV that spins up when you open a door) that is shutting down the power to the computer and causing this issue. I owned a 2002 Tahoe before this and loved it. When this truck is running, I have no issues with it, but within the last week I have had this issue 4 times as we were loading and unloading things for the holidays on numerous occasions. For the GM Customer Service person monitoring this forum, I'd love to know what my options are to resolve this once and for all. To add insult to injury, my rear defrost cable disconnected from the rear window last night, connector and all. Can someone point me in the right direction other than another brand?

I have a 07 Tahoe LT Flex Fuel and have had nothing but dead battery problems. It has left my children and I stranded many times and I always have to call AAA for a jump start. If I leave it parked for more then one day it will not start and the battery is drained. I thought the battery was the culprit but just bought a brand new one and I am having the same problems with the battery going dead. It is !00% stock and I make sure everything is turned off and I still keep getting this problem. Obviously this is a huge issue as I have read so many people having the same issue. They need to make a recall and get this problem fixed. I have been a loyal Chevy and GM customer but if this problem isn't resolved asap I will definitely not buy or recommend Chevy or GMC again. I will let you all know if this problem does not get resolved.

This 2007 model seems to be the culprit - and after thinking about it, you are right on the battery issue - it is stone dead when they jump it, but it starts right back up if you turn the car off - that doesn't make sense. Like I said in earlier post - they claimed it was a corroded battery cable and we haven't been jump started since the last visit to the dealership when the "repair" was done. And again, problem started day 1 when we brought it home so the battery cable was brand new - so it wasn't the problem that day - which makes me think you are on to something.... I still think they did a different repair and just aren't saying so.....
#155 of 252 Tahoe dead battery
Jan 07, 2011 (4:09 pm)
By reading all of these posts, I see that I am not alone in the dead tahoe battery issues. I currently own a 2007 Tahoe LTZ, which occasionally does not start. I have a new battery, new alternator, and new battery cables all replaced, only to have it not start again. Once boosted it can be turned off and started right up again. You can listen to the radio, or lock and unlock the doors, but all you get is a click and the clock re sets itself and you can hear that there is power to the vehicle. The dealer has said they did an update to the (BCM) and now say we should change the fuse panel box!! I am very frustrated and have no intention of changing this! Does anyone have any suggestions as to what can be done??
