Selected complaints filed with NHTSA by 1999 Chevrolet Silverado 1500 owners, lightly cleaned up (personal details are redacted by NHTSA).
The frame and suspension has overly corroded. The frame is falling apart so bad that when I shut the driver's door chunks of metal fall to the ground. I've had it assessed and they say it should not be this bad. Even in Michigan

Frame failed. Cracked at torsion bar cross support both sides. In that section can push screwdriver thru frame. Entire frame flaking large chunks, spare tire falling off. Has previously replaced gas tank straps, new ss brake lines. Fuel lines now rusting through. Sandwich plated with steel/bolts. Frame repair more than value of truck. Has 108,000 miles, about 1/2 of miles I expected to get out of it.
I have a 1999 Silverado 1500, in the past few day I've been hearing a noise coming from the drivers rear wheel area. Today I put the rear of the truck on jack stands in order to locate the noise, after removing the wheel and tire I noticed the frame behind the tire has holes rusted through and is paper thin. Then I noticed a plate welded to the outside of the frame apparently by the previous owner behind the plate the frame has been broke . I then checked the other side and it too has a plate but doesn't look as bad. Now, growing more interested I began poking at the frame walls and in many places its chipping and going through like ice. I am not a rich man and cannot afford to repair or replace something that should last like you would think a frame should. …
Brake line blew out due to corrosion when pulling to a stop light, was able to stop the truck w/o incident. This was 8aug09. Repaired on 12aug09. On 5aug11 went to replace shocks thinking they were shot, problem discovered, entire shock mount rail assembly had rusted away from the frame and is hanging in the air. Mileage: 148876. On 30sep11 gas tank dropped to the ground due to corrosion of frame, and also exhaust system components have rotted away from the frame and now hanging, there are also some cracks in the frame, mileage 149476. There is no rust or damage to the body on this truck at all. It still looks like a new truck. The frame is rotting away from under the truck. I should have bought a Ford. Will never buy another Chevy. From what I see, this is a known problem that GM knows all about and refuses to do anything about all these trucks. …
I have a 1999 Chevrolet Silverado and my ABS light and parking brake light has came on recently. The braking on my truck is not very good in wet conditions. I found that it is a common problem on Chevy trucks, and I was told that I should just remove the fuse. I was told it has something to do with the wheel hub assembly, and it is a costly fix. I think for once Chevrolet should step up and put out a recall on this problem. There is also another common complaint about my dash cluster, which I had also found is a common problem, the odometer will go off and on when it feels like, and the gas gauge frequently goes up and down, and the fuel light comes on periodically. Thank you for your time.

Driving into a parking lot and when I turned and went into lot (there was a slight decline) and then flat parking lot. I heard a loud noise and the bed of the truck pushed into the cab as the frame snapped. There are 12 other known instances that have notified GM and they have refused any action to correct. My 3 yr son was in the truck when this occurred as well as my wife and fortunately we were not injured.
While driving 60 MPH the consumer heard a loud rattling noise and pulled over. The vehicle was towed to the dealership where the mechanic informed the consumer that the problem was in the rear end suspension. The problem has not been resolved. The dealer rebuilt the rear differential.
