Vehicle looses power and brakes go out then dies,doesn't matter speed. If slowing down and press the brakes, the locks, lights, and security goes crazy. This is dangerous as it is in intersections and caution for collision. The vehicle has to be off for a time frame and restarts fine and can go. Happened when coming from ramp and in middle of road with semi truck coming down by us.

The vehicle's ABS and brake lights are on. I took the vehicle in for repair and a state inspection. The part to repair the ABS and brake light are on national back order with no definite availability date. The truck is not usable because of the failed state inspection.

Upon start up of the truck, the ABS light stayed illuminated and started chiming at me. Everytime I start the truck this happens. I had my brakes inspected and they were fine. I currently do not have ABS. I took the truck to a mechanic this last week and had it looked into. It is a known problem with the chevy avalanche and they informed me that there is a part for this problem but it is on indefinite backorder. What and how does that happen? The ABS system is throwing fault codes stopping it from working properly but there is not a part to replace it. Per chevy!

First incident of speedometer intermittently working occurred in september 2005. Was taken to dealer, and quoted to fix but was not covered under warranty. Other cluster gauges began failing completely over the past few years. Finally the voltmeter gauge completely fails this year. Entire cluster is completely inoperative now.

In may 2012 I bought a used 2004 chevy avalanche 1500. About two months later, I noticed issues with my speedometer. I first noticed it on a small trip where I was traveling about an hour or so, then all of a sudden, the speedometer dropped to zero. I pulled over for a minute to see what might be wrong, and it seemed that after the truck was shut off for a bit (need to cool down??), it started working ok again. This has happened several times since then, not usually on short runs, but more when the truck has been running for a while. Another issue with the speedometer was when I was hauling a small utility trailer, and going up a hill, it did it again. Someone told me to check out recalls and I found this site where I see that many, many others are experiencing the same, or very similar issues. If there are so many with these same types of issues, why isn't the manufacturer doing anything about it, or at least investigating it? I am military, and I cannot afford any type of motor vehicle violation on my military record, nor can I afford a speeding ticket...just like everyone else. My permanent address is tyrone, pa, but I am stationed at ft. Benning, ga where I bought the truck. Since I live in barracks, I've listed my permanent home residence in pa. Phone contact number is good, and any mailings should go to the address provided below.

The vehicle's speedometer was sticking for about 5 miles. Then, the vehicle's speedometer stopped on 60 MPH permanently. The speedometer has been stuck at 60 MPH and poses a signifcant safety hazard. Also, several other owners have had the same issues with this model 1500 series chevrolet pick-up truck.

Was driving my 2004 chevrolet avalanche 1500 down the road, when I noticed that my speedometer was acting funny. Was moving erratically in upward increments of one mile per hour, while sticking and jumping on each increment. Then, it just flat quit! Not knowing the mechanics of my vehicles speedometer (ie; speedo cable, electronic, or what have you), went online to search this out. Found out that there are many, many of this incident happening with consumers. Seems that gm refuses to recall this, even though it seems to be a very common problem?? Have read that this can cost upwards of $600 to repair? Just bought this truck/avalanche (used) from a dealer in portland, oregon. Can I get any help with getting this repaired? From my understanding of what I have read (online), there are several "step motors". These step motors are apparently a poor (design) product, and are the same for the speedometer, tachometer, fuel gauge, etc. Also read that because they are all built by the same manufacturer, that (eventually) they will all fail? It is my contention that gm is fully aware of this, from the information obtained (online). I am hoping that this will be repaired for me, free of charge, thru gm?? How do I know how fast I am going? What if I get a ticket? What if my other instruments fail?
