I was driving home from errand running and found the brake pedal going almost to the floor. Found a puddle of brake fluid under the truck near the back of the cab and bed of truck. Called my service person and he said it was probably a ruptured brake line, and from the description of where the puddle was it was probably above the gas tank where the line is secured to the frame. He also stated that he has repaired multiple Chevy trucks with the same problem. I have seen the underside of my truck and all the lines are rusted, including fuel and transmission cooling lines.

I was notified by a GM service center that the brake lines were very rusty and needed replacing.. while replacing the brake lines, I was told that the fuel lines were leaking, needing replacement and also the fuel sender unit needed replacing due to corrosion. This was a very costly repair and should not happen on a low mileage vehicle. I was told that this is a big problem on many GM trucks. I think I should be reimbursed for these repairs.

I was traveling on a side road after leaving my home and as I approached the stop sign at the intersection of a main road I applied the brakes and the peddle went all the way to the floor. I actually went right through the stop sign and almost hit another car traveling on the main road. On inspection of the vehicle I found that the brake lines that travel from under the hood along the frame to the anti-lock module are all severely rusted and one had a hole in it. This is a dangerous situation and GM need to do something about it. I am very upset about this because there were little kids in the car I almost hit and I would hate to think of what could have happened. I also noticed that the fuel lines in the same area are also very rotted. This doesn't usually happen unless the vehicle is much older.

The contact owns a 2004 Chevrolet Silverado. The contact stated they received a letter approximately one year ago from the manufacturer stating that the instrument panel warranty was extended to seven years and 70,000 miles. In addition, the contact was advised not to bring the vehicle in under the warranty unless the fuel gauge had completely failed. The contact stated that the speedometer had been stuck at 120 mph. Later, the speedometer independently dropped below zero and remained stuck there. In addition, the engine RPM gauge would fluctuate sporadically but the engine would not respond. The contact took the vehicle to the dealer and was told that the failures were not covered under the extended warranty for the instrument panel and was advised that the entire instrument panel would need to be replaced. The failure mileage was 116,000 and the current mileage was 117,000. Updated 7/18/12

3 times while climbing a hill, the engine has suddenly, without warning, lost all power, then died leaving me coasting down the highway. Engine is very hard to restart, but will restart if it sits for a few minutes. If this were to occur in an area where I cannot get off the highway, or while passing someone, it could be catastrophic. This has always occured while climbing a hill. Was returned to GM dealer after the first occurance, they stated it showed a lean code, they had no idea what to do. A week later, it stalled twice on one trip. Was returned to GM dealer again, they put another ground wire on the computer, said they had been having computer problems in vehicles lately. I have been afraid to let family in it and have not driven it since the last trip to GM dealer.
