#407 of 456 Persisting Electrical Problems with 2008 Tahoe
Feb 09, 2013 (5:34 pm)
I have had the same issues with my 2008 Chevy Tahoe. In the past 3 weeks it has been in the repair shop at the dealership I bought it at and after each time they claimed to have fixed the "going dead" problem by replacing a BCM and a module sensor,... the problem still persisted. So... after the 3rd time the dealership refused to do anymore service on my vehicle...... so I took it to another GM dealership and they did a diagnostic and determined that my navigation radio wasn't fully turning off after I turned the vehicle off causing my battery to slowly drain and eventually kill after a couple days. They said I would need to replace the radio. I didn't want to spend the $1300 so they unhooked the radio so my battery wouldn't drain. Well... this was about a week ago... and just today the "Service Battery Charging System" light came on along with the red battery light. I immediately took it to an autoparts store and they tested the battery which came out as being weak. So... the dealership bought the vehicle from couldn't figure out the problem... but still cost me diagnostic fees, inconveniences without a vehicle, etc, and now what I thought was a radio issue.... could be something totally different now. I am to my WITS end with this hunk of junk.
I have spoke on the phone with 3 different GM customer relations representatives and they were as much help as the place I purchased my vehicle. How many things, that are the SAME issues, to all these different GM vehicles have to occur before a recall is done and customers get some satisfaction instead of just dishing out money for diagnostics, parts, etc. and nothing is ever fixed. I will never buy another GM product. Worthless!!!!!

Ok, I've read post after post after post of these same electrical problems with no real solution. Did anyone ever truly get theirs fixed?
Mine is having the same issues while driving, door locks going up and down, gauges moving back and forth, lights flickering, sometimes the tahoe shutters, and this usually happens anywhere from 3-10 seconds. And when this does occur, when I get to my destination and shut off the car, then it always goes completely dead. Then I can hear a intermittent clicking noise coming from the door locks and under the dash, but nothing works at all. I always disconnect/reconnect my battery cables, and it always temporarily solves the problem. This may happen a couple of times a day or it may drive normal for a month or so. I bought the tahoe used in april 2012, and it did this off and on until around oct 2012. Then it ran perfect up for about 6 months, and now yesterday it did it again.
I don't have a ton of money to throw at it, and I usually do all car repairs myself, but this has got me stumped. Any help would be greatly appreciated.

We had this problem and threw a bunch of money at the problem and it was eventually fixed but we probably got somewhat taken (bunch of parts replaced). I've kept up with the posts that have had similar problems and it seems like it is always related to bad grounding. This could be at the battery, at wherever the main ground is on the engine, or at the megafuse on the passenger side of the firewall. I would definitely make sure all your grounds are clean and tight before I threw any big money at it.

The problems I have with my 2007 XLT is just a dead car situation. It appears to happen once a year and right before we leave for spring break. Two weeks ago it happened again. I opened up the hood and removed both battery cables and connected them together for about a minute. I have heard this acts like a system re-boot. Put cables back on the battery and the truck started right up. Guess I am good for another year.
To the Chevy employees watching. Please do not respond and tell me you are happy I have found a fix or that it is great the car is working again. This is not a fix to a problem that is serious and causes all of us grief.
Hope this helps others avoid the dealership or local shop.

So the ground was the issue? How long has it been since you've had any issues with it? I guess i'll try adding a couple more ground wires.
Another thing I've noticed is that a lot of us are in Texas, so I was thinking it could be something getting too hot, which could be ground/wire related.
Thanks for the input!
#412 of 456 Has GM Customer Service given up???
Apr 21, 2013 (9:11 am)
So I had started the route of trying to weave through GM's Customer Service tangled web, and one of their reps contacted me regarding the issues I had brought up in a forum regarding some issues I was dealing with.. After trying to to go through a dealer, then with a district specialist and even his supervisor I maintained contact with a rep (Louis) from this forum.. After talking with the supervisor, I tried to get further information from Louis for continued pursuit and wasn't getting any response... Today I tried to email him and he no longer has an account to email to??? Has GM decided Customer Service matters so little to them that they closed that department down and let them all go???? Guess since the government bailed them out, they don't need to worry about customer satisfaction (or safety) anymore...

It has been a few weeks since my latest issue then a year before that. I am in northern Nevada where it is cold in the winter so no correlation to heat.

#415 of 456 Inconsistent Door Lock Function, Electrical Anomalies
May 14, 2013 (5:34 am)
My 2003 Tahoe has recently been experiencing several electrical issues. It sporadically needs to be jump started even after normal use and no lights left on or doors open, and door locks started having a mind of their own. I just replaced the 4-year-old battery but now the door locks are on a rampage! They lock and unlock in different sequences, sometimes randomly while parked, and the radio wont turn on (as though its security setting has been activated). I'm also getting a very rough idle when the A/C turns off and on. I've had two shops check voltages and everything comes up clean between the battery and alternator. Is there some kind of system reset that can fix all this? My hoe is a mess!

I just purchased a 2008 Tahoe last week and I am already experiencing electrical issues. I had my husband disconnect the battery cable and replace them, which fixed the problem, temporarily from the sounds of it. Why is it that GM cannot figure out the problem with this??? This is a serious problem with vehicles shutting off while driving, not starting up, locks trapping people inside...these are not minor issues and it is obviously a rampant problem. It took me 5 minutes to find numerous sites complaining of the same issues. What is GM doing about it?
