GM bulletin PIP5847A
What it saysThis Preliminary information communicates the possibility of a misfire or rough running concern and abnormal engine noise due to excessive wear in exhaust roller follower axle pin. NHTSA’s full summary ↓
GM filed this with NHTSA as a service bulletin dated Aug 2, 2023, received Sep 18, 2023, about the back over prevention. It names 10 model years across Chevrolet and GMC (2019–2023). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is GM PIP5847A 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 PIP5847A 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 PIP5847A cover?
The manufacturer filed it against 10 model years across 2 brands (Chevrolet and GMC): 2023 Chevrolet Silverado, 2021 Chevrolet Silverado, 2019 Chevrolet Silverado, 2022 Chevrolet Silverado 2500HD, 2020 Chevrolet Silverado 2500HD, 2023 GMC Sierra and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
