GM bulletin PIT6180
What it saysThis Preliminary information communicates assistance in locating the Rear seat belt comfort guides in the parts catalog. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Aug 13, 2024, about the seats. It names 191 model years across Chevrolet, GMC, Buick and Cadillac (2017–2022). 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.

Read by machine from the document NHTSA serves (1 page), 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 190 model years this bulletin names have filed 26,427 complaints with NHTSA since 2015. 6 of them name Seats — 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.
1. What component or system failed or malfunctioned, and is it available for inspection upon request? The passenger seat adjustment mechanism has failed, causing the seat to become stuck in the farthest rear position. The malfunction is likely related to either the motor, seat track, or the electrical system controlling the adjustment.

2017 Chevrolet Impala · Seats · filed with NHTSA Dec 24, 2018

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIT6180 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 PIT6180 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 PIT6180 cover?
The manufacturer filed it against 191 model years across 4 brands (Chevrolet, GMC, Buick and Cadillac): 2019 Buick Cascada, 2018 Buick Cascada, 2017 Buick Cascada, 2022 Buick Enclave, 2021 Buick Enclave, 2020 Buick Enclave and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
