GM bulletin PIP5865C
What it saysThis Preliminary information communicates the possibility of DTC P30BF failing on low mile vehicles due to the possibility of the cylinder 1/2 sliding barrel binding on intake camshaft. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Aug 13, 2024, about the fuel/propulsion system. It names 21 model years across Chevrolet, GMC and Cadillac (2019–2024). 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.

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.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIP5865C 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 PIP5865C 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 PIP5865C cover?
The manufacturer filed it against 21 model years across 3 brands (Chevrolet, GMC and Cadillac): 2024 Cadillac CT4, 2023 Cadillac CT4, 2022 Cadillac CT4, 2021 Cadillac CT4, 2020 Cadillac CT4, 2024 Chevrolet Colorado and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
