Read by machine from the document NHTSA serves (5 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.
Affiliate disclosure: some links on this page are affiliate links. If you request a quote or buy through them we may earn a commission at no extra cost to you. Nothing on this page changes because of it.
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 13 model years this bulletin names have filed 606 complaints with NHTSA since 2015. 61 of them name Visibility/Wiper, 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.
The contact owns a 2020 Chevrolet Camaro. The contact stated that after opening the convertible top, the sliding door used to secure the convertible top into the rear of the vehicle malfunctioned and failed to automatically close. While attempting to manually close the door on the convertible top, the contact almost injured a finger.
2020 Chevrolet Camaro · Structure · filed with NHTSA Apr 10, 2025 · ODI 11653937
Whenever the A/C is running the defrosters stay open and badly fog the windshield on the inside...gm is aware and has fixes that do not work. I have attempted to have the dealer and GM correct it (it appears to be extremely widespread as a problem)...gm responded that the car functions as it was designed. I find it dangerous
2018 Chevrolet Camaro · Visibility/Wiper · filed with NHTSA Mar 22, 2019 · ODI 11190921
The rear window of this car has separated and when I contacted the manufacturer they indicated a service bulletin was issued but they are not liable for the repair. The window has become more and more separated and I'm using glue to hold it on but it's becoming undrivable due to the risk of it separating while on the road.
2017 Buick Cascada · Visibility/Wiper · filed with NHTSA Feb 15, 2026 · ODI 11718080
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 17-NA-216 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 17-NA-216 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 17-NA-216 cover?
The manufacturer filed it against 13 model years across 2 brands (Chevrolet and Buick): 2019 Buick Cascada, 2018 Buick Cascada, 2017 Buick Cascada, 2016 Buick Cascada, 2024 Chevrolet Camaro, 2023 Chevrolet Camaro and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
