Chevrolet filed this with NHTSA as a service bulletin dated Jan 8, 2024, received Feb 12, 2024, about the power train. It names 7 model years (2016–2022). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Chevrolet PIP5548B 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 PIP5548B 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 PIP5548B cover?
The manufacturer filed it against 7 model years: 2022 Chevrolet Spark, 2021 Chevrolet Spark, 2020 Chevrolet Spark, 2019 Chevrolet Spark, 2018 Chevrolet Spark, 2017 Chevrolet Spark and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
