What 2005 Chevrolet Avalanche owners say
Electrical system all 21 →
The speedometer sticks at a speed and will drop to the 6 o'clock position. This is a know issue among owners but GM nor the dealerships are willing to acknowledge or fix it. This is the second issue with my vehicle that GM is not willing to fix or take responsibility. I will never purchase another GM vehicle again.
Speedometer stopped working completely. It had been working fine when I last drove it. But when I started driving within the next 3-4 hours I noticed it was not reading the speed at all. All the other gauges on the cluster were working properly. When talking to the dealership about this problem they stated it wasn't a simple fix and could cost me above $500, they couldn't give me an estimate of how much it would cost. .after reviewing the complaints listed on this website, this seems to be a manufacturers defect. Many other owners of this same vehicle have had the same complaint and its rare that it functions properly in any of the vehicles. Even though my vehicle is over the warranty period I believe that the manufacturer should stand behind their work and correct this problem. A recall is definitely in order.
Air bags
The contact owns a 2005 Chevrolet Avalanche. The contact stated that while starting the vehicle, the passenger's side air bag warning light was illuminated. The vehicle was taken to an independent mechanic and diagnosed that the passenger's side air bag was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 16,900.
Was driving home on the highway and swerved hitting the divider with the front left corner of vehicle. The seatbelts did not hold me in my seat and my head shattered through the window striking the street light lamp. Airbags also did not deploy meanwhile I was on the highway going about 57mph. The injuries were drastic including partial amputation of my ear, I was in a coma for a few week, 3 skull fractures, tbi, brain bleeding and the list of injuries continue to grow!

On 12/22/12 @ 5 pm- shortly after entering onto the freeway, I started losing power. I didn't get higher than 50 MPH before the RPM started increasing & my speed started decreasing. I got off the freeway, at the first exit, approximately 2mins after the beginning of the loss of power. Found a mechanic that was just closing his shop & asked him to give a quick check too see if I could continue my drive home, 32mins away. The mechanic checked under the hood & under the bottom & guesstimated the problem to be the flywheel. The mechanic also recommended no driving til repaired.
