Cadillac bulletin N242440670
What it saysService Update - Certain vehicles may have a condition in which the tie rod jam nut may be below torque specification. NHTSA’s full summary ↓
Cadillac filed this with NHTSA as a service bulletin dated Apr 29, 2024, about the steering. It names 2 model years (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 N242440670 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 N242440670 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 N242440670 cover?
The manufacturer filed it against 2 model years: 2024 Cadillac CT4, 2024 Cadillac CT5. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
