“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.”
NHTSA complaint #10323585, filed 2010-04, 110,000 miles“I have had problems with my dash cluster it pins itself at high speed and the amp gauge and temp gauges stop working too I had this problem just after buying it and it had 125000kms on it and chevy said it was over the kms too be covered to me their should not be a time frame or mileage set too have them replaced ...please let me know if their is anything that can be done ...thanks”
NHTSA complaint #10259434, filed 2009-02, 125,000 miles“The speedometer on my 2004 Chevrolet avalanche indicated a rising speed while, in fact, I was decelerating to try to meet the speed limit (I thought). The needle continued until it was completely off the scale while actually doing about 65 MPH. Now, at a stop, it registers about 45 MPH and varies with actual speed.”
NHTSA complaint #10181050, filed 2007-01, 56,000 miles“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.”
NHTSA complaint #10172639, filed 2006-11, 37,000 miles“My 2004 avalanche speedometer no longer operates, it says I am going 120 miles per hour and 70 miles per hour when stopped. I checked a web site and this seems to be a standard problem with this vehicle and I think this should be a recall.”
