Selected complaints filed with NHTSA by 2004 Chevrolet Avalanche owners, lightly cleaned up (personal details are redacted by NHTSA).
Tl* the contact owns a 2004 Chevrolet Avalanche. The contact stated that while driving 25 MPH, the steering wheel became hot. The components on the steering wheel illuminated and upon further investigation the contact noticed that the wires had melted. The contact also noticed that the radio became very hot and melted the cd inside of the system. The contact also stated that the instrument cluster failed. The manufacturer was notified and stated that they would pay for a new instrument cluster, but not the installation. The failure mileage was 30,000 and the current mileage was 146,000.
While driving or in park the tachometer sticks as does the speedometer. This has lasted from minutes to days. The vehicle appears to run properly, however, I am very leery of my safety and the safety of my children when they are in control of the vehicle.
While driving all my cluster gauges froze...I was parked and it still said I was going 40mph...how is this not a recall? No clue how fast I was going,nor how much fuel I had...we should be reimbursed something.
The speedometer has malfunctioned on several occasions. Most recently July 24, 2007. I was driving down a highway and it jumped to 75mph -approx 20mph faster than I was actually doing. Upon coming to a complete stop, the needle settled on 21-22mph mark. The needle doesn't move smoothly either. It jitters as it moves and jumps more as it is fixing to come to a rest. After turning the vehicle off, then back on - the needle will fall about 5mph. I had turn shut off / restart several times to get the needle back to 0mph. Today, I drove to work and didn't see a problem outside of a jittery needle. Previously the speedometer has stopped all together while driver and settle on 0 MPH or will max at 35mph while driving. At these instances I would pull over, turn the vehicle off and back on to no avail. …
Failure has occurred twice on my 2004 Avalanche surrounding the inefficiencies within my dash board. The speedometer was reading incorrectly. It was very dangerous as the accurate speed was not reporting. I was able to get this replaced at about 40,000 miles. Recently, the gas gauge is not working correctly. After filling up the tank and taking a road trip the gas gauge immediately reported an empty gas reading. The gas gauge continues to read incorrectly and fluctuates. I have contacted the company to find out that there is a service warranty on the vehicle up to about 70,000 miles. Currently my truck is at 86000 miles all due to highway traffic to work (30 miles each way). I do not feel that I should expense this cost since this is clearly a factory issue. Regardless of the number of miles on the vehicle if it is a known defect it should be covered. …
My 2004 Avalanche speedometer and tachometer read completely inaccurate. Example=shows me going 120mph and 3000m RPM with motor off. I bought the vehicle used from a Chevy dealer and was told it had warranty remaining. When the problem began last year I was told it was not warranted. I lacked the money for the replacement and have been driving it broken. Now I am finding out through other Avalanche owners that it has been being fixed by dealers at no charge as there have been so many problems. I feel this should be a recall. I know my vehicle now has 110,000 miles, but I can document by law enforcement notes on a ticket I received last year that I had the problem about 30,000 miles ago. I feel this should be repaired at no expense to me. …
Over the last few months I have noticed that my 2004 Chevy Avalanche speedometer suddenly goes off by 10-80 miles an hour. There are no events that "cause" this to occur, it appears to do it randomly. I notice it when the vehicle suddenly appears to be going faster or slower than the speed indicated. I tried contacting the dealer for repair but they have ignored my online repair appointment submittal. The upsetting part is that my warranty just ran out. This is a major problem and needs to be fixed. Luckily my cell phone has GPS and will indicate ground speed. I can use it to verify the vehicle speed. I am lucky that I have not gotten a ticket or killed. I have a photo of my speedometer nearly pegged out at 115 miles an hour to prove it. I have never driven my vehicle that fast. I heard that others are having problem with GM SUV speedometers. This appears to be a wide spread problem.
Was driving at a rate I thought was around 65-70 MPH but got pulled over for going 84 MPH. I explained to the officer I was only going about 68 MPH. He then showed me the radar gun and it said 84mph. When I went back to my truck I noticed my gauge was stuck on 18mph I showed the officer and luckily he told me ha had the same problem with his Chevy truck and let me off with just a warning. To make things worse all gauges don't work now. I've read some messages online and some people said they got letters to repair this problem. I've been the only owner of this truck since May 2004 and never received anything about this problem. I believe GM should repair the problem because it's a big safety issue. Please help. Thank you
Tl 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.
My 2004 Chevy Avalanche is having a problem with the speedometer. I was on a cross country trip and it started going past 120 when I was driving 10 MPH in the snow!!! The it sticks at whatever speed it feels like sticking on.. My RPM gauge has been acting a bit funny also. It didn't work at one point just last night. I turned the truck off and restarted it. I can been able to "reset" the speedometer by almost turning the truck on until it gets back to "0", but I am afraid this will eventually break my starter. This is a safety issue (even though GM says it is not) because if speed wasn't a factor in auto safety we wouldn't have speed limits! How can a consumer be safe if they cannot tell how fast they are driving?
