Extreme rust, tailgate cables broke in use, had to replace. Tailgate still won't latch properly, dropping open while driving/hauling fairly often; brake line rusted out, replaced before had accident; whole frame rusted - under carriage//tire wells/drive shaft/around reece hitch so I worry about pulling trailer/hailing. Horn has rusted off. Only 77,000 miles as I do not drive it daily, just to work around my place or pickup/haul/trailer something. GM needs recall to address this rust issue because it is a major safety issue.
Here I am 2016 and the third time I have to replace rusted corrosive brake lines and fuel lines. This time I only put 3500 miles on the truck since the last time. They are on the verge or blowing out, the first two times they did and lucky was able to stop. The fuel line is gone again also. Why??
My 2001 Chevy Silverado 2500hd with the 8.1 engine will stall at anytime. It has happened when sitting idle, taking off from a light, and I've even had it happen doing 50 MPH. I refuse to let someone borrow my truck because I'm afraid they will panic and get in an accident. It is especially dangerous since you lose power steering and basically have no control of the vehicle. Sometimes I can drive for 50 miles and not have a problem and other times it will stall twice in 30 minutes. So there seems to be no rhyme or reason. I do not understand why there has not been a recall issued for this problem.
Brake, fuel, transmission cooler, and power steering cooler lines became very rusty and eventually leaked. Most lines have been replaced at this point, and a few still need to be. I bought the truck used in September 2005 with 72,010 miles on it and problem had already started. Fuel level sensor has failed twice, and requires replacement again. Power window motors on both sides have each failed twice. Truck now has over 150,000 miles, and I'm only reporting because many of these same troubles appear to be common on later model Chevy/GMC trucks.
Tl contact owns a 2001 Chevrolet Silverado 2500 hd. The contact stated that after having a routine maintenance performed on his vehicle they advised him that the brake and fuel line were completely corroded. The mechanic advised him that all of the lines underneath the vehicle needed to be replaced due to the severe corrosion. He was unable to drive the vehicle since it was inspected for fear of the parts on the vehicle becoming detached. The manufacturer was not contacted. The failure mileage was approximately 87,700.
2011: I lost my brakes while hauling 2 horses in the mountains of western maryland. As I was traveling downhill, I was extremely fortunate to have been able to turn into a business that was "uphill" an used gravity to stop. This was extremely scary. I had my truck towed and learned that my brake lines rusted out. 2014: I took my truck in to have an oil change and learned that my fuel lines were leaking. I had no warning and obviously I replaced them. I have also replaced my air conditioning twice.
Tl* the contact owns a 2001 Chevrolet Silverado 2500 hd. The contact stated that while driving 45 MPH the vehicle stalled while attempting to change lanes. The vehicle was taken to an authorized dealer, who stated that that all eight injectors and the injector pump needed to be replaced. The manufacturer was made aware of the failure and informed the contact that the vehicle was not under warranty and there were no related recalls. No other assistance was provided. The failure mileage was 143,000.
The under carriage of my 2001 Silverado hd is heavily corroded. The brake lines are leaking and all need to be replaced. I was backing my boat in the water and had a brake line fail. P/s lines are corroded and fuel lines are corroded. I have owned this truck since new and have taken great care of it. The lower cab corners are rusted out as well. This vehicle has around 90,000 miles and is not driven often in the winter months.
6.6 diesel fuel rail leak. Can fuel dripping on exhaust manifold create fire? Service man at dealer said he had another last week. The same rail is apparently used on 2001 through 2004 model years.
My truck was parked outside my house and this drunk driver hit my truck in the middle of the night.and mest up all of one side of the truck including my engine,baby seats and tires and windows.
