Frame And Members Problems of GMC Sierra 2500

The contact owns a 2022 GMC Sierra 2500. The contact stated that the subframe was severely corroded. The dealer was made aware of the failure; however, the vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 500.

Major rust of the undercarriage of my 2005 GMC serria 78000 miles. So far had to replace brake rotors, brake lines , fuel radiator and lines. Frame and cross members as well as control arms are all rusted. Made complaint with GMC they had me bring to a dealer to tell me this is normal rusting. Two of my relatives have the same year truck but are not experiencing this issue and we all live in the same area drive same roads.

I was parked in a friends driveway and was about to leave when I released the parking brake stepped on the brake pedal and put my 2002 GMC 2500hd truck into gear. I started driving down the street and approached a stop sign, when I applied the brakes the pedal went straight to the floor. I pulled off to the side of the road and opened the hood when I noticed brake fluid all over the frame in the engine compartment. Upon further investigation I found all the brake lines to be severely rusted and at least one of them ruptured. I was driving with my 9 month old son at the time of the incident and thank god nobody was coming the other way down the road. I had the truck towed to my home where it sits awaiting a total brake line replacement. The underneath of the truck is so severely rusted I think GMC is liable and should issue a recall to correct the problem.

I was approaching an intersection in my 2004 GMC sierra 4x4 2500hd pickup truck with a 2800 pound trailer when I pressed the brakes to stop. The brake pedal went to the floor and I was unable to stop. The trailer brakes were not enough to stop the vehicle and I continued into the intersection and was almost struck by two other vehicles. They just missed hitting my vehicle and causing serious injuries to myself and my passenger, as well as themselves. When I opened the hood there was brake fluid all over the drivers side of the engine compartment. I had the vehicle towed to the nearest GMC dealer. The dealer told me that a brake line had burst and needed to be replaced. He also stated that all the brake lines were corroded and needed to be replaced at $750. 00 per side. He told me that this was a common problem for these vehicles and that these lines only last 4-7 years on average. There is also significant corrosion on the frame. My vehicle is always garaged and regular maintenance is done. The dealer then told me that since we live in a snow belt state that I should expect this and that GMC will not help with the repair. I told him that I am very upset and that I have been a firefighter/paramedic for over 25 years, and if what he just said was true, then I would have had to rescue an awful lot of people from their crashed vehicles if on average brake lines only lasted 4-7 years. I feel that this needs to be reported and investigated because it is a very serious safety issue and people are going to get hurt if what the dealer told me is true. I would appreciate it if you would look into this matter. At this point my vehicle is sitting at the dealership in an unrepaired condition until further action by either GMC or NHTSA happens.

Broken frame on the front by the front shock mount I have seen several on other 2500 and 3500 series GMC and Chevrolet models I have had to weld and plate the frames on 2 of my own trucks.

Consumer stated the vehicle vibrated excessively when traveling between 40-60mph. Dealer diagnosed that a defective frame flex was causing vibration and there was no remedy.
