Rear half of Frame Crossmembers rotted away between the Frame rails. Took vehicle in for routine safety inspection, and the mechanic determined that the cross members to which the rear shocks and the Gas tank were attached had both broken free from the frame rails due to rust. The entire back end of the vehicle is suspended from the frame with only the leaf spring mounts. This rust is excessive and far exceeds the rust on other points on the frame and undercarriage of the vehicle.

I’ve only had the truck for 1 years and the frame is so deteriorated and rusted. My frame is now cracked/damaged. I’ve read up on the same manufacturer/trucks and it seems like an ongoing problem.

The contact owns a 2013 GMC Sierra 1500. The contact stated that while driving at an undisclosed speed, the contact was alerted by another motorist that the spare tire had lowered underneath the vehicle. After stopping to inspect the vehicle, it was discovered that the rear cross members had corroded, causing the spare tire to become unsecured underneath the vehicle. Additionally, while driving over bumps in the roadway, the vehicle became unstable due to the corroded rear suspension. The vehicle was taken to the local mechanic who diagnosed that the rear sub frame needed to be replaced. The vehicle was not yet repaired.

The interior and exterior door handles broke on both doors on my 2013 GMC SIERRA truck. There was no warnings and my safety was at risk because the only way to enter or exit the vehicle is to crawl out the window.

On 8-25-20, I took my 2013 gmc sierra to an automotive repair shop in genesee, wi, for a brakes and shocks inspection/repair. They refused to work on it because they said the frame was 'broken and cracked' due to excessive rust perforating the frame. The service manager told me my sierra should not be driven because it is unsafe, especially since the worst frame damage is immediately adjacent to the gas tank. I was shocked because my vehicle is in otherwise excellent condition! On 8-26-20, I called and sent photos (see attached) to the service manager at the gmc dealership in waupaca, wi, where I had purchased the vehicle new. He stated he would not drive my sierra and nor should I. He referred the matter to his gm rep to set up an official gm pet case. The case was subsequently refused due to 'no history' at the waupaca dealership. They suggested I call a gmc dealer in waukesha where I do have an established history. The service manager there also said my sierra should not be driven and that 'the frame could buckle if put on a hoist.' he also refused to help me. On 9-2-20, I contacted gm customer care and received an escalated case number. On 9-9-20, a senior advisor from customer care said she would look into the matter but could not guarantee anything because the vehicle was 'out of warranty' with its 115,000 miles. On 9-17-20, the advisor said the only thing gm would do is offer me a $2,500 allowance if I would trade in my gmc for a new model. I rejected this offer as I firmly believe the rusted and perforated frame is a manufacturer's defect and should be recalled. This is obviously a serious and dangerous safety issue that all owners of 2013 sierras should immediately be made aware of!

Paint above the windshield is separating from the primer in large sheets. One large area approximately the size of a volleyball with multiple small areas along the edge of the windshield across the top. Also has an area on the right rear quarter panel the size of a half dollar where the paint separated from the primer and fell off. Vehicle stays parked most of the time in the garage. I first noticed the paint peeling after coming out of work where the vehicle had been parked in the sun.
