The undercarriage or frame of our recent purchase of our 2003 used chevrolet k1500 silverado was discovered recently after purchase to be rusted through and through and chipping off day by day. A private master mechanic has looked the truck over and said that it was not safe to drive. Upon further investigating, the panels that hold up the roof of the truck underneath the interior panels are rusting through and through to the point of breaking. Dealership we bought it from just shrugged their shoulders and said basically oh well, it was sold as is. under the truck on the frame where the wheels are attached, forgive my descriptions but im no mechanic, looks like they can break off at any minute. …
I have a 2003 Silverado and upon arriving home I felt my brake peddle go to the floor and I couldn't stop and backed into my trailer, I got out of the truck and noticed a huge puddle under my driver side wheel. After investigating I found that the steel hydraulic line had rusted & broke. I am disabled with 4 auto immune diseases and cannot afford to put it in the shop so I ordered the part, replaced it and proceeded to bleed the line and found that 3 other steel lines had holes in them or had rusted all the way through. I also have rust all under the truck. I will have to replace the two front support braces as they have rusted all through. At $120 each. So from front to back all the steel lines have rusted. I was blessed to have had this happen in my drive. Had I driven another mile or so I could have been killed. I now have a fear of driving. …
Just leaving home to go look at some parts for a pole barn and left driveway went to stop sigh , I proceeding to go down mitchell hill rd and on the second turn no brakes , luckily I have some experience in this area and instantly applied my emergency brake and put truck into lower gear . This was enough to slow me down so I didn't go over the guard rail but did hit it roughly . I made it to the bottom and coasted to a stop . Got out and looked under hood and truck to find brake fluid was pouring on to the ground. I had it towed home . Upon further inspection I located the cause of brake failure was due to brake lines broke due to heavy rust all over them .. Now I do a little research online for replacement parts and find out that this is a serious issue with many owners of Chevrolet Silverado's . Why hasn't their been a recall . …
I just bought my truck about a month ago. I was under it changing the oil and I noticed an alarming amount of rust on the frame members and the brake lines. Some of it looks so bad that I am concerned of having either frame breakage or a brake line failing. I have read many other stories of the same thing happening to other trucks. I have not had a failure yet but I believe it is just a matter of time. After reading all of the horror stories from other owners on various web sites, I am terrified every time I drive it that the brakes are going to fail. I cannot afford to spend $3000 to $4000 to have the truck fixed. Especially when I consider it a manufacturer defect of a safety item. Please issue a recall for these problems before people are injured or killed because the frame has broken or the brakes have failed.
In bumper to bumper traffic for aprox 4 mins and stopping and starting hit the brakes , peddle goes to floor hitting car in front of me because no brakes.

While driving home on 5/1/2014 traffic stopped short. I hit the brakes to stop. The truck stopped OK. Traveled about another 2 blocks and when I hit the brake pedel to stop. It went to the floor and I ad no brakes. I hit the back of another car due to not being able to stop, after the truck was towed to repair shop it was found to have rusted, broken brake line. This caused the truck not to stop. The insurance company wound up totaling the truck due to the damage.

My wife and I own a 2003 Chevrolet Silverado z-71. The car is 8 years old with only 17,714 miles on the odometer. It has been parked outside on my asphalt drive way. The vehicle looks to be in perfect condition. I took the vehicle to a non-general motors repair shop to have the brakes looked at. After the vehicle had been hoisted up and inspected, I was asked to look at the amount of rust on the frame, differential housing, brakes, calipers, etc. The rust was so bad that it was literally flaking off the frame and differential housing. The mechanic was concerned about the safety of driving the vehicle. On July 22, 2011, I took the vehicle to the dealership (sullivans o'neill's Chevrolet and Buick, inc. In avon, ct) that I had purchased the truck from. I was advised not to drive the truck a lot as it was, in the service manager's opinion, unsafe. …

The cable mechanism that is fastened to the frame of the underside of my pick-up truck along with the spare tire fell from my truck onto the highway. This mechanism is what holds spare tire under my truck bed and has a winch with cable that raises and lowers the tire. The mechanism slides under steel support on side and is secured with a bolt on other side. The steel base around the bolt cracked and broke loose. Fortunately I lost my spare tire during daytime conditions and on lightly traveled road or a vehicle behind me could sustained damaged and passengers could be hurt. My truck is a Chevrolet 2003 Silverado 1500 2wd work truck model. I bought this truck new and have had few problems with it. I have just over 80,000 actual mile on the odometer of my truck.
