There is a GM recall #05068C- product safety- front wheel speed sensor corrosion. The 2002 Avalanche is listed, but my 2003 is not. I live in Indiana, one of the states listed in the recall. My 2003 Avalanche has this failure and should be covered by the recall.

Avalanche 4WD 8-cyl

  • 110,000 miles
One day while driving at 55mph the truck just shut down. Everything electrical completely shut off. Luckily I was able to control it. I turned the vehicle off and restarted it. It was fine but did it again when I stopped at a stop sign. It continued to do it but then just stopped. Check engine light goes off and on all the time when I accelerate up a hill. The lights on the dashboard are dim. Everything on the mirror comes and goes. It will go months without working and then comes back on. The suspension is terrible. Feels like it's going to shake the wheels completely off the truck when I hit even a small bump in the road. I've almost lost control several times due to it shaking so hard. Latch on the tailgate broke off and needs to be replaced. Rotor on back completely broke and had to be replaced.

I went to primm Nevada for a off road race and notice that at high speeds the tires develop a pull to one side. I have had the truck aligned and not able to fix the pull. The tires are pro comp extreme all terrains.

Purchased a used 2003 Chevy Avalanche at a dealership in Feb 2006 upon servicing the vehicle two months later was told that the car had extensive under carriage rust. This car originated in Michigan but I am wondering if it was a katrina vehicle during auction? recently had problems with U-joints which had to be replaced. GM mechanic says the rust is extensive and caused this problem it will need a lube kit to re-lube all the mechanics under the truck. None of this under carriage body rust was disclosed to us upon purchasing the vehicle in fact the dealer told us he only gets the best used vehicles. There is also a problem with the steering column which makes a clunking noise when turning the wheel - the mechanic at the GM dealership says this is a know problem.

Avalanche 4WD 8-cyl

  • Automatic transmission
  • 1,000 miles
The vehicle was very unstable during crosswinds which caused the vehicle to sway left or right unexpectedly. The tire air pressure was found to be 4-5 P/si lower than the design valve. The pressure was increased to the proper valve brought the vehicle handling and the steering response back to a stable condition.
