GM bulletin PIT6181
What it saysThis preliminary information discusses driver assist functions that may be disabled due to incorrect tire size. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Aug 15, 2024, about the wheels. It names 14 model years across Chevrolet and GMC (2018–2024). 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.

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.

When flat towing behind a motorhome, per manual instructions, going on or off a highway ramp....cloverleaf, the tires will squeal like they are dragging. This does not occur every time, however 75% of the time it does. A very loud screeching, dragging or braking, pulling the motorhome down from 35mph or 40mph to 10mph.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIT6181 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 PIT6181 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 PIT6181 cover?
The manufacturer filed it against 14 model years across 2 brands (Chevrolet and GMC): 2024 Chevrolet Equinox, 2023 Chevrolet Equinox, 2022 Chevrolet Equinox, 2021 Chevrolet Equinox, 2020 Chevrolet Equinox, 2019 Chevrolet Equinox and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
