#309 of 459 Sick of Electrical Problems
May 29, 2012 (6:07 am)
I have a 2005 tahoe that I bought with 15k miles on it. I bought the extended warranty through 88k and glad I did. I have had 3 transmissions, 2 4wd sensors, rear AC actuator, and something in the steering column under the warranty AT $100 a piece for deductible. I have 105k on it now and I am still having tons of issues. Rear AC went out almost 12 months to the day it did before and the dealership stated that it wasn't the actuator part that would be under warranty it was the housing around it (quoted at $400). I am having all the same issues with the reduced power message when i try and downshift to accelerate. I replaced the wiring and plug for the throttle and it didn't work. The dealership told me that the butt splices that come with the ACDelco part that i put in would not work and that I should solder them so I now have to try that. They recommended that if that didn't work i should replace the throttle body. We shall see. Not a year ago i was getting the Service 4WD light and i called the dealership to see what it could be. The advisor recommended that i put it in 4WD once a month in and around the yard and it should fix it and IT DID! Until today when i did it my normal route around the yard and got the Service 4WD light again after. I turned the truck off and back on and now the entire dash switch is out and i can't even put it in 4WD. I am sure they will want $500-$1000 for that one too. I would trade it in if i could do a new payment now but can't. Guess i will have to keep trying to fix myself! Never buying a Chevy again unless it is pre-80's with NO electrical anything!!
Seems that everyone is have one or more of the same issues!
#311 of 459 2007 Tahoe - Multiple Electrical Failures
Jun 15, 2012 (9:44 am)
I have been having the following problems with 07 Tahoe - 1) the rear wiper doesn't work; 2) the window on the rear lift gate won't open; 3) the driver's door lock will not work with the FOB or the panel button; 4) the driver information center (odometer, gas mileage, air pressure readings, etc.) is dead.
My dealer just diagnosed the vehicle with a short in the rear lift gate, a broken actuator in the door, and the need to replace the instrument panel cluster. Total cost is $1300. Based on my research, these all seem to be common problems with Tahoes of this era, but GM has not issued any recalls. Has anyone gotten anywhere by appealing directly to GM to cover some of the costs of these repairs. It seems like things like this would make their consumer satifaction ratings take a plunge. I'm not sure if I will stick with GM next time around.

The last few months my 2009 Tahoe has been what I called possessed. The dash dings and blinks most of the time, the "stabilitrak" light flashed off, door knobs go up and down without warning, car alarm goes off for no reason, hestitates when accelerating at times which is very dangerous, a/c panel will go from 60 degrees to 74 and every light on the panel lights up so I have to set it back to where it was before the dash went bananas and not on 3 occasions, I will get in to go and nothing! Its like the battery is dead but I hear clicking on both driver and passenger side door where all the window and lock buttons are, my gauge needles are moving up and down slightly while making a buzzing noise. All of the noises sound like and electrical wire is barely connected but when we took it to the dealership for the day, they say they can find anything wrong. Said the even called GM to ask questions and got no where. Like others, I love my Tahoe....when it is doing what it is suppose to do. It only has 59k miles on it. Sometimes I think I will walk outside and its on fire or something or worse I can be driving thru a busy intersection and it stalls out. Nancy2009 and I have the same problem but no results. On friend told me the thought it was the body control module and would be expensive to replace as they have to reprogram everything which sounds wrong all the wa around. If it is something to this magnitude, then I feel GM should fix it as it is not like an alternators, battery or something that is normal when it goes out although nothing should be going out on a 4 yr old vehicle...

I had the exact same problem. My local mechanic here replaced what he called a 'mega fuse'. It's located on the firewall under the hood next to the battery. It cost me $107 out the door for diagnositcs and repair. Mechanic said the connectors were barely making a connection. My truck has been running fine for approximately a month and a half (fingers crossed). You might want to give that a try...

I feel your pain! I have spent a lot of time in contact with GM as well as the dealership that I bought mine at. They did replace the wiring to the battery and my car has not had all of those issues since. Until last week when I set the keys on my seat and the car began locking itself and locked my keys in the car (which I do all of the time because my parents live in the middle of nowhere.) So tomorrow they are coming to get my car to replace the body control module. I loved my car until now.....now I feel as though I have no clue what it may do. GM and the dealership have basically said its my problem. GM offered me a "customer loyalty package" so that I could get rid of it (probably for them to sell to another unsuspecting victim.) They offered me 2000 dollars to use on another car....and said they could do nothing about the loss I would take on the vehicle which is definitely more than 2000. Its amazing that taxpayers bailed them out a few years ago! I would suggest having them look closely into the battery wiring/fuse...I am considering seeing a lawyer as I am 7 months pregnant and have a 5 year old daughter, and I am fearful this car could kill us! GM and the dealer won't really care until it happens.....so sad

I think this is what they did at dealership....mine has been ok until the locks began acting up again! Did you have your batter changed previously? And how many miles do you have on it? I am just trying to see the amazing "coincidences"!

My Tahoe had the exact same problems and after taking it in 7 times to the same dealer, I took it to a different Chev dealer and they immediately found that the negative battery cable was bad. They changed the cable and I never had the problem again....The first dealer I took it to claimed they checked the battery cable and there wasn't anything wrong with it.

I had the exact same symptoms with my Tahoe. After a few days of checking everything they replaced the negative battery cable/terminal AND reset the computer to clear all the old errors it was throwing. initially my dealership hadnt cleared the errors and reset the comp so the problems started happening again. Once they did both of these two things the vehicle operated normally. havent had any of these issues since then.
