Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI54.10-P-078915 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 LI54.10-P-078915 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 Mercedes-Benz warranty extension on file lists the ones Mercedes-Benz has filed.
Which vehicles does LI54.10-P-078915 cover?
The manufacturer filed it against 1 model year: 2024 Mercedes-Benz AMG GT. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
