general problems of the 2003 Chevrolet Avalanche

It started with the airbag light, but nobody will own up to fixing it, as we moved from PA to FL. Then the brake lines went, all of them, now with the airbag issue the pcm is sending all kinds of stupid codes like the airbag issue is affecting the whole electrical system in the truck.

The contact owns a 2003 Chevrolet Avalanche 1500. The contact stated that the low coolant level warning light illuminated intermittently. The vehicle was taken to a dealer where it was diagnosed that the cylinder heads were fractured and allowing coolant to inadvertently enter the engine. As a result, the engine needed to be replaced. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 125,000 and the current mileage was 129,000.

Engine light and reduce engine power and start loosing speed. After turned off for a few minutes work fine. This year in an hour ride have to stop at least 20 times. Computer codes stated need to change throttle body. Last week I change it and again the same problem.

For the last year or so my 2003 chevy Avalanche has had an intermittent problem of throttling down when I hit about 60 mph. The error words pop up of "reduced engine power" and I have to pull over (after negotiating highway traffic to get to shoulder with no power) and turn engine off and let it sit for a few minutes before starting it. Sometimes it does it multiple times in the first hour of driving. Seems to do it more when the weather is colder than when hot.

Shortly after refueling the vehicle the consumer smelled a fuel odor. He stopped the vehicle and as he pulled the hood release he saw flames shooting up onto the windshield. A police officer nearby attempted to put the fire out using a fire extinguisher. A second police officer arrived and emptied his fire extinguisher before the fire was put out. The engine compartment was completely burned out. The vehicle was totaled. The cause of the fire is unknown.
