I am a new owner of a 2003 avalanche, I was satisfied with my purchase but my soonroof falls under the appropriate serial numbers (6,000,000-6,300,000) recall states that it may be covered by the company webasto hollandia. Vehicle is fine to drive places but sunroof must be fixed for coming winter. It worries me as there's a slight danger of it causing a road hazard if it were to fall out.

Tl* the contact owns a 2003 chevrolet avalanche 1500. While driving 60 MPH, the vehicle failed to accelerate. The instrument panel gauges fluctuated independently and several warning indicators illuminated. The vehicle also stalled. The contact was able to restart the vehicle, but the failure recurred multiple times. The vehicle was taken to an independent mechanic who diagnosed that the vehicle had electrical issues. The vehicle was not repaired. The manufacturer was not made aware of the issue. The approximate failure mileage was 230,000.

I was driving approximately 15 to 20 MPH down a hill that was curvy and all of a sudden my truck completely shuts off as I was driving down the hill and almost went into a ditch because the truck just shut off while in drive and luckily I was quick enough to put it in neutral so I could steer it away from the ditch and I turned the ignition over and luckily it turned on while in neutral otherwise I would of crashed into the ditch. Then it shut off again about 30 seconds after and luckily I was able to put it in neutral again so I could steer and coast down the hill because it wouldn't start up the second time when it all shut off. I was stranded at the bottom of the hill near a light so I tried to start it again and it would keep trying to turn over but wouldn't start again. I was stranded in the middle of the road and had to call aaa to tow my avalanche to my house. This could of killed me if I wasn't quick enough to figure out to put it in neutral to be able to steer. There should be a recall on whatever made this happen and I still don't know what is wrong with it because it happened late last night and I was looking for recalls and it doesn't show anything on this.

Key ignition switch is loose and car will shut off while operating, key can be pulled out of ignition while running. If vehicle shuts off while operating then you loose control of brakes, steering, and electrical systems. Gm is denying there is a problem. My vehicle is proof that the problem exists and the chevy avalanche 2003 has a problem.

In light of the recent information concerning gm's intentional withholding of problems with the ignition switch in certain gm vehicles, I feel compelled to share my story. I do see other complaints filed here concerning the same issue. In october 2003, I purchased a new 2003 chevrolet avalanche 1500. The vehicle had 5,500 demo miles on the odometer. I drove many miles for work and for transporting hockey kids to practice, games, tournaments, etc. In december 2006 I already had 80,000+ miles on the vehicle and the speedometer, gas gauge (causing me to run out of gas in the middle of the night!), oil gauge, battery voltmeter, rpms, which are all components of an electrical cluster began failing. I contacted my gm dealer and was told that a 'silent recall' had been issued to dealers stating that if a vehicle with less than 3 years and under 70,000 miles was brought in, the dealer should fix the item as a warranty repair. Since my vehicle was 2 mos over the 3 yr and over the 70,000 miles, I was denied a warranty repair and quoted $700.00 to fix the part. Since that date, my son's chevrolet vehicle had the same problem! And, in 2009 a friend's brand new denali with less than 10,000 miles had the same problem. I have never fixed the problem due to cost and disagreement with gm. I wrote the corporate office and got nowhere. I don't see how a safety issue like this can be allowed to continue to happen nor how gm can know about the problem but not tell owners of the vehicle and/or future possible buyers of the vehicle. Oh wait, yea gm doesn't say anything because consumers might take their business elsewhere! I simply wanted to gm to fix the problem, that was obviously known about, but rather, gm simply keeps putting the same bad component in future vehicles!!

I believe the same problem with the gm key/ignition switch is more common then what is being reported. The avalanche 2003 has had the same loose ignition switch for years. Our key system has to be jiggled and forced to the start position 80 percent of the time. The ignition switch will also move the off position while the vehicle is moving and the key will fall out.

My speedometer and several gauges have been acting erratically for months, and now the speedometer battery gauge, and the oil pressure gauge have stopped working completely. In researching the problem, I have found out that there was a recall to fix this problem several years ago. I never received notice of this recall. I have lived in the same location since 2001, but have never been notified of the recall. If there was a recall affecting the instrument panel, I would have taken it in. Why didn't chevrolet notify all owners?
