#302 of 418 2009 Tahoe Electrical/Computer Issues
May 10, 2012 (11:03 am)
I purchased a used Chevrolet Tahoe in July 2011 that had 35000 miles on it. About 3-4 months ago the vehicle would not start several times. I took the vehicle to the dealership where it was purchased, and I was told that the battery was bad although I had taken to Autozone where they assured me that the battery reading was fine. The battery was replaced at my cost as I was told that this was not part of the extended warranty I had purchased. Approximately a month ago the message "Stabilitrak off" began flashing periodically A few days after this began, I picked up my 5 year old daughter from daycare and as we proceeded to drive home, the locks began locking/unlocking repetitively, chiming, multiple warning lights, and the vehicle seemed unresponsive to the gas pedal so slowed at an alarming speed. I pulled over and turned the car off and was able to drive home. This happened again approximately 2-3 days later while accelerating at an intersection and again when I was leaving work. I contacted the dealership and took the vehicle in. After the technician drove the car over 40 miles (at my expense of gas), I was told that they could not locate the problem but to contact him if it happened again. Unfortunately for the consumers with this faulty system, they are only able to "diagnose" the problem if it happens in their care and because there is no warning for when this could take place, this is virtually impossible! The car did not have this issue again until yesterday when my mother was in the car and we were traveling back from my prenatal appointment in Houston, Texas on the freeway when this happened again while traveling approximately 65 mph. We were fortunate enough that there was not a car behind us when the car unexpectedly felt as though it went into neutral and began all of the above mentioned chaos again. This was incredibly scary at such high speeds for myself and my mother. I am currently 6 months pregnant and again as I mentioned have a 5 year old daughter. I feel as though we could pull into any intersection or on any freeway and could have this malfunction. I have purchased a lethal weapon on 4 wheels to put my family and myself in daily. I took the car back to the dealership this morning and expressed my grave concern as well as contacting safecar.gov and GM. I feel as though GM is disregarding the seriousness of this matter and wants to wait until my family or someone else's family is killed to react. The manufacturer is responsible for the proper and safe production of their products, are they not? McDonalds can be sued for serving coffee that was too hot but GM can allow their consumers to play Russian roulette with vehicles?

Nancy 2009 -It sounds like you have read a number of posts before yours and yes, it is scary when your vehicle goes into "limp mode" and you're in cross traffic or any traffic for that matter. If you're in the Houston area I can tell you that there are no dealers that "specialize" in electrical problems with gm vehicles. I finally took my 09 Tahoe to Lonestar Auto Electric on the southwest side of town after getting nowhere with the chevy dealer up in Humble. Lonestar did find multiple problems and did fix the car and I drove it for around 6,000 miles to Florida and Maryland with no problems but it did have an episode of door lock cycling a few weeks back but that may have been related to the negative battery post coming loose. We tightened it and no problems since. The only other place you could try is a Christian Brothers shop on the west side off of hwy 6 near Bissonett, I think. However, if you take it to any shop other than a dealer they must have a Tech II scanner with up to date software in order to diagnose GMLAN issues. Good luck.

Thanks so much for your reply and advice. My car is still at the dealership right now; I do not live in Houston but I do go there to see my doctor. I am going to make technician aware of this. I spoke to the GM at the dealership as it is also the dealership that I purchased the car at. I am still uncertain as to how GM can continue to ignore these expensive vehicles with such safety concerns; what angers me the most is the attitude regarding these issues as if it is no concern to them. I plan to continue on this pursuit for some sort of rectification of the problem. I do not think that GM or the dealership that I purchased the car at should be comfortable with me driving off with the vehicle that could malfunction at any given moment with no warning. It seems as though these automotive companies do not have to react until someone is killed and they are publicly scrutinized. I do, as I said though, intend to not let this issue go until I can be assured that I am in a vehicle that is safe for myself and my family. I do not believe that we should have to make the news for GM to think that this is an important issue.

Ok so my truck started acting up again by doing the chiming, door locks up and down, radio cutting on and off etc. I took it the mechanic and when I cut the truck off it wouldn't restart. No power, no clicking, nothing. Anyway, my mechanic (been going to him for years) ran a battery of test on the truck and found that the 175amp fuse on the firewall was shot and was barely connecting, which made the truck cut in and out. Fuse replaced and truck has been running great. Truthfully, I'm still pretty hesitant to say that it's fixed, after reading some of the other posts on here about multiple trips to the mechanic. Fingers crossed.

bran164 - Can you be more specific on what fuse it was an where it is located? My 09 Tahoe has a fuse box in the engine compartment and another fuse panel inside the vehicle on the side of the dashboard just across from the driver's door but I can't find a fuse panel on the firewall. Thanks

The 175 amp fuse I am referring to is located against the firewall on the passenger side under the hood. If you're looking at the battery (on the left) from the front of the truck it should be located above and slightly to the right on the firewall. It's not inside of a fuse box or anything like that, it's a stand alone fuse.
#308 of 418 Info Needed for Problems With 2005 Tahoe Z71 2WD
May 27, 2012 (9:34 am)
My wife and I have a 2005 Tahoe Z71 2WD that was purchased in 2010 with 80K miles. The vehicle has numeous upgrades. After driving the vehicle for a few months the following problems occured: 1) The dual heated seats started working intermittently. Over time only one could be turned on at a time but it would not stay on. 2) The ABS warning light began flashing with the warning alert dinging 33 times each time it activated. This began happening every time we drove the vehicle. A diagnostic test showed it to be the ABS module which is mounted on the drivers side frame (Dealer part priced at $1030.00. I found a used one at LKQ for $375.00. Only the top portion needed replacement. 3) The transmission went out without warning at a little over 100K miles (We were 150 miles away from home for the weekend when it happened and had to rent a car and be towed back home. A short inexpensive getaway ended up costing a fortune.) I replaced the transmission with a used one that had 69K miles, Hope it lasts. 4) the illuminated buttons on the steering wheel do no illuminate. I have asked mechanics about it but they are leary to mess with it due to the airbag. 5) some speedometer cluster lights are out. 6) One side of the A/C temperature selector does not illuminate 7) The fuel gauge will go from displaying nearly empty to all the way full without adding fuel. This also affects the Miles To Empty feature as if the tank was just filled up so if we didn't track our mileage we would think the tank was full and run out. 8) The passengers side mirror turns down intermittently as if it were in curb view and the mirror has to be re-adjusted. 9) The Driver 1 and Driver 2 seat settings do not stay programmed. 9) Occasionally the A/C blows hot air on the drivers side but stays cold on the passengers side. 10) The vehicle gets HORRIBLE gas mileage no matter how slow we drive or what octane fuel is used.
I know the post is long but any suggestions for any of the above problems would be greatly appreciated. We still owe too much money on the vehicle to get out of it so I would like it to work in a manner that all of the ammenities we paid for can be enjoyed.

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 418 2007 Tahoe - Multiple Electrical Failures
Jun 15, 2012 (10:44 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.
