GM filed this with NHTSA as a service bulletin dated Jun 29, 2023, received Jul 17, 2023, about the structure. It names 8 model years across Chevrolet and GMC (2019–2022). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 5,746 complaints with NHTSA since 2015. 107 of them name Structure — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
I originally bought a new 2019 Chevrolet Silverado 1500 ld on 06/08/2019, I really liked the truck and its many features. After several weeks I noticed the whole underside frame and driveline components were rusted and corroded. I brought it back to my dealer and they immediately located a replacement vehicle for me.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIT6036 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the PIT6036 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way. Every GM warranty extension on file lists the ones GM has filed.
Which vehicles does PIT6036 cover?
The manufacturer filed it against 8 model years across 2 brands (Chevrolet and GMC): 2022 Chevrolet Silverado, 2021 Chevrolet Silverado, 2020 Chevrolet Silverado, 2019 Chevrolet Silverado, 2022 GMC Sierra, 2021 GMC Sierra and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
