Chevrolet Avalanche owners have reported 4 problems related to battery (under the electrical system category). The most recently reported issues are listed below.
Truck failed to start due to dead battery after sitting for less than 24 hrs. Since purchase 5/07 it has occurred 6 times--7 if you count the day of purchase. Truck is dead again today and is at the dealership (12/6/08). This vehicle starts immediately after being jumped. They can never find anything wrong, and no stored codes whether I jump it then take it in or tow it in. They suggested that I was leaving accessory items plugged in-of which I was not. All recalls have been addressed. Dealer/gm will not admit a problem exists and replace the vehicle without a huge financial debt to me. Vehicle was purchased new, one owner and currently has 19000. Original complaint after purchase was 10/07 and 6475 miles.

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.

Instrument panel - puff a smoke and very strong electrical burning smell came out from under the dash on the drivers side irritating drivers (my) eyes. Fuel, oil, battery charge, and water temp gauge needles all swung around to the 7 pm clock position. Indicating a short circuit and over current situation through the gauges. Driver information center (dic) went blank and then slowly came back on and would intermittently go blank. Transmission shift lever position indicator went blank and then came back on. Gm dealer removed and replaced instrument cluster panel. Gauges, dic and transmission shift lever indicators now work as they are suppose to. In test drive of 50 miles, still get and occasional smell of burning electrical odor, about 1/2 as strong as original when the instrument panel shorted out.
