Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

I own an 04 Chevrolet Avalanche and the tbc2 fuse always blows. So I have no dash lights to show me my speed or anything. I have read up on this and lots of these trucks have the same problem with wires rubbing and shorting out. As well as the service air bag light comes on as well which I think is another thing with wires being in a bad spot and shorting out.

The contact owns a 2004 Chevrolet Avalanche. The contact stated that the speedometer would display inaccurate readings and failed intermittently. With the assistance of a navigation system that would read the traveled speed at 55 mph, the vehicle's speedometer would display over 100 mph. In addition, the fuel gauge failed and the oil gauge would display that there was no oil in the vehicle. Most of the gauges and components on the instrument panel became inoperable. The dealer stated that there were too many miles on the vehicle to assist and it would not be covered by the extended warranty. The repair cost was estimated at over $1,000. The failure mileage was 92,000 and current mileage was less than 130,000.

I have a problem with the speedometer showing inaccurate speed on my 2004 Chevy Avalanche. The problem started while I was slowing from 55mph to 45 mph do to a reduce speed area, the vehicle slowed but the speedometer said at 55mph. It stayed at 55mph even when I came to a complete stop, shut off the vehicle and restarted, when I put the vehicle in gear and started moving again the speedometer began to move up to 60mph when I was traveling approximately 10mph. I sped up a little more and the speedometer climbed more. I slowed down to a stop and this time the speedometer stopped at 60mph while I was at a complete stop. I turned around to go back home as I could not legally judge my speed and as I proceed to travel at my best estimate 50-55 mph the speedometer climbed up past 120mph. When I parked the vehicle at home the speedometer showed 65 mph. I opened the hood, disconnected the battery and let it sit unconnected for approximately hour and then reconnected the battery. This did not help, the speedometer still showed 65mph. I contacted my local Chevy dealer and asked them about the problem I was having, they told me that since I have over 40,000 miles on my vehicle that I would have to pay 400 dollars for a new cluster. This is a safety issue and it should be covered under warranty. I can not drive my vehicle for fear of inadvertently speeding and thus getting one of those nice driver awards for speeding. Please help resolve this matter.

The instrument panel on my vehicle is displaying the incorrect information for fuel level and oil level. This is occurring at startup and continues while I drive the vehicle and is a constant problem. Nothing has yet been done to correct the problem but feel that the manufacturer should assume financial responsibility of correcting the malfunction.

While driving approximately 50 mph my speedometer began to read 120 mph. I consider it a driving hazard (safety) when driving on the highway and in traffic. Very distracting. When I investigated on-line I discovered that this is a well documented defect. The cost for repair is over $400 and should not be bourn by the consumer for a known defect.

Speedometer has become erratic at zero to 120 mph at any given time or any where inbetween truck running or setting still. Will be traveling down the road at flow of traffic and speedometer will be zero to 120. This is very dangerous. GMC or federal government needs to issue a recall. This is a problem common to GMC Chevy products Silverado truck, Impala, and Avalanche vehicles 2003 to 2005.

Driver side power window stopped working, locked in closed position. Nothing leading up to it. Happened in Oct 2007 (1 month out of warranty). Finally took to dealer for repair in Oct '08. Dealer replaced motor and regulator $588 cost. Complained to Chevy in Dec '08, they said small plastic part had failed but since it was past warranty and I waited 2 months to complain, there was nothing they would do. They also said it was a known, infrequent problem and they were redesigning the mechanism.

Oil gauge began to show low pressure then no pressure. Carried to dealer, they replaced oil sensor on engine. Problem still occurs but only after vehicle has been driven for a couple of hours straight. Now the pressure gauge pegs to the right. However, once the vehicle has been turned off for the night, it performs correctly and I have been unable to get it to demo for dealer as it only does it on long trips which occur on weekends and night.

Instrument cluster went out mph kept fluctuating, and A/C and heating has a mind of its own goes on and off and in strength of blowing, all this which I hear is common in 04 to 05 Chevrolet trucks. Even a Chevrolet mechanic told me when fixing my truck said it was pretty common in these years 04- 05. And he didn't know why it doesn't have a recall.

Here's about my disappointment with my 2004 Avalanche which I purchased on July 28, 2004 with 137 miles on the odometer. I purchased the value guard GM protection plan. Of course, the vehicle was great for the first 37,990 miles. My first problem came on 10/31/06, only 2 years 3 months after purchase date. My tailgate handle broke while opening it handle replacement was $568. To my surprise and apparently also to the representative from the dealership the existing spoiler had to be torn off and replaced with a new one to access the handle. That was an additional $186 plus labor. I question the designers of the tailgate assembly. Why would anyone design parts that would have to be destroyed in order to service another part" in fact, why would any part that would normally be used frequently by a regular trucker break so easily" of course, neither the warranty nor the GM protection plan covered this. The next problem occurred on 12/27/06 at 41,901 miles, my windshield wipers wouldn't shutoff. Into the dealership we went and $334 later a wiper board was replaced. No warranty again covered this problem. I no sooner got home and had to return on 12/28/06 at 41,944 miles. Now my dashboard light service 4 wheel drive was on. This time I was told the transfer case encoder shorted out and $779 later it was fixed. I might have used the 4-wheel drive 8-10 times at the most. At that time, I'd owned this vehicle for 29 months, that's pretty sad!! today with the latest episode, I tried to lower my front passenger side window and it wouldn't work. The other 3 windows work fine. I waited and tried again later still no luck. I hear a clicking sound but no action.this probably means another visit to the dealer.

The speedometer on my 2004 Chevy Avalanche does not work properly. When I am going 25 mph it indicated 80 mph. Sometimes when I am stopped the speedometer indicates 30 mph. Basically the speedo works sometimes, but I cannot rely on it to drive safely-at any speed, because I do not know what speed I am actually going.

Driving down the interstate my speedometer suddenly quits and says I am driving 120 mph (even while parked). This is a 2004 Chevrolet Avalanche with only 28,000 miles on it GM needs to recall this because of the frequency this is happening with Avalanche owners.

  • Automatic transmission
  • 54,000 miles
My 2004 Avalanche started making knocking sounds when turning corners - took it to the dealer and $700 later and a new steering yoke the knock was squelched (not gone) and the speedometer coincidentally started moving like a second-hand on a watch (jerky) - took it to the dealer and they want $525 for a new cluster that they say is not common - looking on the web, I found this to be a very common problem with Avalanche and the waiting list can be in the hundreds before me - if this is so common, why isn't there a recall and why does the dealer deny the number of occurrences?

: the contact stated while driving at 60 mph the vehicle lost power without warning causing the speed to decrease to 30 mph. The sudden loss of power occurred ten times, but the vehicle was taken to the dealer on six occasions for inspection of the problem. The dealership replaced the throttle body twice, but the problem persists. Updated 2/7/2006 -

Avalanche 4WD

  • Automatic transmission

The electricity from the automatic control monitor that controls the air conditioning and temperature control on the roof of the truck was causing the consumer to experience severe headaches and she was no longer able to drive the vehicle with the heat or air on. She had to pull the fuse that controlled the monitor because turning it off the wave of electricity was still flowing. The gauss meter that checked the wave of electricity was flashing red when she held it up to her head. It was not suppose to be like that. The symptoms were: Her scalp was real tender and swollen, her left side of shoulder and neck was hurting a lot, and she had to use contacts in her left eye because of vision problems. All of these symptoms were from the automatic control monitor she has never had any of these symptoms prior to this. Since she unplugged the fuse these symptoms disappeared, and she felt better. Her concern was that other people driving this vehicle may never be able to figure out what caused these problems and she felt that this was a severe health risk.
