Cadillac bulletin PIP5858A
What it saysThis Preliminary information communicates ordering process for the front and rear drive unit restriction for the 2023 - 2024 Cadillac Lyriq NHTSA’s full summary ↓
Cadillac filed this with NHTSA as a service bulletin dated Jan 5, 2024, received Feb 12, 2024, about the power train. It names 2 model years (2023–2024). 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Cadillac PIP5858A 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 PIP5858A 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 PIP5858A cover?
The manufacturer filed it against 2 model years: 2023 Cadillac Lyriq, 2024 Cadillac Redundant Lyriq. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
