What 2003 Chevrolet Silverado 1500 HD owners say
Brakes all 49 →
Brake lines rusted through and ruptured resulting in total brake loss and a crash. The lines failed at a point directly under the driver seat. It was in motion on a city street and struck another vehicle also damaging that.
Jan. 2014 in northeast illinois I went to apply brakes for a red light and peddle went to the floor. I was fortunate that there was not another vehicle already stopped at the light in front of me, and was not hit as I coasted through the red light. I was able to use the parking brake for stopping while I maneuvered to my home. Upon inspection the next day, I found the brake line that runs along the truck frame and feeds brake fluid to the front brakes had ruptured. I was astound when I saw the condition of the remaining brake lines under the vehicle and the fact that the lines were not made of stainless steel or some other material that would not rust when exposed to the road salt that used heavily during the winter months in northeast illinois. I'm also concern about the fuel lines because their condition is the same as the brake lines and appear to made out of a ferrous material also.

My whole dashboard stops working the gauges lights everything just stopped working. I was traveling down interstate and everything stopped working but after a few seconds it all came back on for about 30 seconds and it all shut off again and never came back on I made it home and turned the truck off and went inside. I got up the next morning to go to work and cranked the truck and no gauges or lights were not working still. I slammed my hand down on top of the dashboard and everything came on and was working but that didn't last long and everything shut off again.

Engine & cooling
Several of the exhaust manifold bolts have snapped/sheared causing exhaust leaks between the exhaust manifold and exhaust port on the cylinder head. I'm learning that this is a common issue that has gone unaddressed by the manufacturer, but is clearly an emissions and functionality issue. Please help in holding the manufacturer accountable for this apparent mechanical defect. As of now, they offer no assistance in repairing the issue.
