What 2003 Chevrolet Silverado 3500 owners say
Brakes all 24 →
Driving through a rural town going about 45 miles an hour, I applied the brakes and they were very soft, brake pedal went near the floor, eased it home on front brakes (as rear line had ruptured). Upon inspection brake line had rusted in two just behind the fuel tank (long section had rusted away). Replaced line going to rear brakes.
I have a 2003 Chevy k3500 Silverado truck, with about 60,000 miles. As of December 2010, I have suffered two brake line failures due to corrosion, wherein a steel rigid brake line rusted completely through, resulting in brake loss. I live in ohio, and salt is used on roads, however, in my 30 years of driving, I have never had another vehicle, regardless of age or miles, which suffered a catastrophic failure of the steel brake lines. In both cases of failure, I was lucky in that I was not in a heavy pressure situation, and luckily avoided accidents. I have now largely replaced the entire brake line infrastructure of the truck, at considerable personal time and expense, however, problems still include the fact that corrosion continuously affects the performance of the front wheel speed sensors as they input to the ABS system. …

While driving home around 10 pm with small children; my truck started to surge, became difficult to control, and the gauges did not register anything ( all at 0). This road was in the middle of nowhere and outside a bad area, so I called my husband to come follow me home and I drove home slowly all the while enduring a chugging motion. What is normally a 20 minute trip became an hour and a half trip. When I got home and shut the truck off my husband looked at it thinking that the fuel injectors could be the problem since they had just been recalled and replaced. The truck would not start when he went to restart it and the dash said 'unknown driver". Through some research we discovered it is a faulty passlock system. We went through the recommendations and it was fixed. …
Electrical system
First complaint for this problem was reported on 10/21/10. Complaint #10361641. Same problem again dtr light on right side out,smelled burning wire saw that the same thing happened again. Wires leading to light assembly melted and also melted the socket again. I think this could possibly lead to some sort of electrical fire in the engine compartment. I fixed the problem myself the first time and will do so this time.
