A well-documented and increasingly widespread problem related to excessive rust on the frames of many vehicles in this particular model year range. The cause of the problem appears to stem from a poorly applied or degrading wax coating, which, over time, peels off, leaving the frame exposed to corrosion, particularly in harsh weather conditions such as heavy snow and road salt exposure. The result is catastrophic—my Silverado’s frame and crossmembers are now severely compromised, and the integrity of the vehicle is in question.

Frame rotted through

The contact owns a 2014 Chevrolet Silverado 1500. The contact stated that while approaching the vehicle, he noticed that the passenger's side exterior rocker panel had detached. The vehicle was taken to the dealer, where the contact was informed that the subframe was severely corroded on the driver's side and on the passenger's side, and the corrosion had extended to the passenger's side exterior rocker panel. The vehicle was not repaired. The manufacturer was notified of the failure, and a case was opened. The manufacturer referred the contact to the NHTSA hotline for assistance. The failure mileage was 110,000.

GM has known issues with their frames rotting prematurely. We bought a 2014 Chevy Silverado 1500 in 2016 and had it undercoated at a dealership that claims it will prolong the inevitable rusting/frame rot. The truck has just under 99k miles and should be worth $15-17,000 and won't pass inspection due to severe frame rot we are told it is very unsafe and not drivable. We will be lucky to get $4,000-5,000 to trade for a part out. Our only other option is to spend $10,000 to get a new frame. GM has known about this issue and fails to do anything about it. Toyota had similar issues and stood by their name and products and replaced frames or gave consumers $10,000+ to make it right. It is not fair to the consumer we cannot win a class action against GM and demand a payout for such massive losses. Had we known our frame was so bad, we wouldn't have dropped over $5,000 in it over the last 11 months for rocker panels, cab corners, shocks, bearings, etc. We are out $15,000 on this truck and GM should be held accountable. There are thousands of people nations wide that are in the same boat hoping GM will be held liable at some-point for the distress they have cause their loyal customers.

Chassis framework has corrosion including perforation of major frame parts near rear wheels and under the fuel tank. Vehicle has only 70,000 miles and has been well taken care of including regular winter weather washings with underbody wash package. This is a known problem and should have been addressed similar to Toyota truck frame problems. Now I have a like-new appearing vehicle which has been well maintained however the chassis frame is now unsafe and in need of repair. This problem should be addressed up to and including frame replacement.

I bought this vehicle used, in February of 2019. Everything about the vehicle was checked and in very good shape. Approximately a year ago, early 2023, I was told that a bit of coating had come off the frame and was beginning to rust excessively. In January of this year during a dealership visit for repairs I was shown an area of the frame that looked like hunks of rust had fallen of, and then I was told this will turn into a major problem. My most recent visit, on March 21, 2024, I was again informed about the frame rust and was shown not only the rust problem, but large cracks in the frame that could not be repaired and is a major safety issue. I find it hard to believe a ten year old vehicle with 89455 miles can be beyond repair without this being a manufactures issue !

I am the owner of a 10 year old Chevrolet Silverado 1500 with less than 82000 miles. Chevrolet has Service Bulletins out regarding frame rust, but I was unable to have a dealership repair the surface rust for the 7 years I have owned the truck. My frame is now rusted out to the point it is not safe to operate and will cost over $15000 for Chevrolet to repair since the Service Bulletin was not resolved during the visits to dealerships for service during the Factory Warranty Period. My truck has never been abused. As Chevrolet stated in [XXX] , this may be a result of a manufacturing issue. This issue is beyond a cosmetic issue and does affect the safety of the vehicle, the driver, passengers, property, and people around. This issue is not isolated to me and my truck, but many others. Thanks to this not being looked at as a safety concern I am now left without a safe method of transportation. Frame rust and deterioration needs to be upgraded to a recall, just as Toyota. The frame build is similar so has the same results. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My roof has started leaking recently in the back part of cab.

The 2014 Silverado I own the frame is rusting through already! Only 168,000 miles and cleaned and maintained very regularly and the frame is rusted so badly its almost scary to continue driving! My 97 Silverado the frame is still solid as can be with almost 400,000 miles on it and my 10 year old truck with half the miles the frame is shot already? Unacceptable!!

Significant corrosion / rust on frame that compromises vehicle safety by weakening the frame. An independent service provider identified large rust hole in frame and multiple areas of significant corrosion. Vehicle has not been inspected by the manufacturer however there are service bulletins for this year, make, and model to correct the manufacturer-identified failed corrosion/rust prevention coating system for this year, make, and model. Specifically General Motors Service Bulletin 19-NA-255. Holes affecting integrity of frame were first discovered in December 2023; subsequent holes and areas of significant corrosions (ie, soft spots) in the structural frame have been identified.

What component or system failed or malfunctioned, and is it available for inspection upon request? Truck failed state inspection because the frame had rust/corrosion holes in. Frame has been replaced @ this time & the old frame was scrapped. How was your safety or the safety of others put at risk? Due to the rotted/rusted frame the reliabilty & safety of the vehicle was compromised & could have resulted in injury, accident or death Has the problem been reproduced or confirmed by a dealer or independent service center? Independent garage verified the defective frame & replaced it w/a new frame. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? After having the frame replaced the vehicle now passed the required state safety inspection. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Some surface rust was visible on the frame but it was not discovered to have rotted holes through until the underside was looked @ for the state safety inspection. It should also be noted that Chevrolet was contacted & provided the same documentation attached within. Chevrolet DENIED any re-imbursement due to the following: "After further review by our GM Reimbursement team, the vehicle is not eligible for a repair reimbursement due to the repairs being performed at a 3rd party. Also the vehicle is outside of the bumper to bumper warranty it would have been covered under by age and mileage."

The frame has rusted to the point that expensive repairs are needed for a truck that's 9 years old. The problem started around 2020, at 120K miles. I already had the gas tank crossmember replaced, only to now have the rear crossmember rust out including the rear of the tailgate. The rear strut is now hitting the bed compromising the performance of the suspension. When the rear strut mount broke, it caught the rear body harness and cut two cables that caused the traction control to shut off while I was driving. I attached pictures of the damage.

Brought truck in for a NYS inspection and it failed due to rust and cracked frame. While it was still on the lift the frame collapsed and the back end fell off the lift. Luckily nobody was under it. This seems to be a common issue on many of the Chevy forums. Something needs to be done before failures like this happen on the roads.
