GM bulletin 19-NA-255
What it saysThis preliminary informational bulletin provides frame coating repair information to correct a customer concern of wax coating on frame peeling, metal shows corrosion/rusting (U.S. and Canada Only). NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Mar 11, 2025, received Dec 3, 2022, about the structure — 6 documents under this number. It names 110 model years across Chevrolet, GMC and Cadillac (2016–2025). 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.
One page for every brand it was filed under. Each brand’s bulletins: Chevrolet · GMC · Cadillac.

Read by machine from the document NHTSA serves (12 pages), read Sep 30, 2026. A part number is shown only where it matches GM’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

What owners reported
Source: NHTSA complaint databaseOwners of the 109 model years this bulletin names have filed 18,967 complaints with NHTSA since 2015. 250 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.
On the 2017 Chevrolet Silverado, the 19 owners who gave an odometer reading for Structure reported it at a median of 7,500 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Tailgate opens by itself, a know issue by GM and Sierra drivers. Mine was damaged by opening and banging against my travel trailer. I have been talking with GM about this since September. Today a different department told me they require up to 30 days to investigate and if I pay for the repairs myself they will cancel the investigation.
2023 GMC Sierra · Structure · filed with NHTSA Dec 4, 2023
This vehicle was sold to me with severe frame damage, which was not reported on the carfax, and was not reported at the dealership. If you turn the steering wheel to the right, you will hear a scraping noise under the right front tire, as the suspension is off because of the frame damage caused from an accident with the previous owner.
2019 Cadillac Escalade · Structure · filed with NHTSA Nov 3, 2023
I was turning left from the freeway feeder light that was already green upon approach. Assk I passed the intersection, I colided from on directly at the front passenger side, impacting the rear driver side of a smaller VW atals. My vehicle spun out of control stopping at the opposite side of the intersection at the median.
2019 Chevrolet Tahoe · Structure · filed with NHTSA Apr 8, 2021
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 19-NA-255 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 19-NA-255 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.
Which vehicles does 19-NA-255 cover?
The manufacturer filed it against 110 model years across 3 brands (Chevrolet, GMC and Cadillac): 2025 Cadillac Escalade, 2024 Cadillac Escalade, 2023 Cadillac Escalade, 2022 Cadillac Escalade, 2021 Cadillac Escalade, 2020 Cadillac Escalade and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
