What the bulletin says

Customers may have received the description of certain functions that are not applicable to their vehicle. MBUSA will conduct a service campaign.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz NCU - 2024030010 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 NCU - 2024030010 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 NCU - 2024030010 cover?
The manufacturer filed it against 4 model years: 2024 Mercedes-Benz AMG GT, 2024 Mercedes-Benz GLC-Class, 2024 Mercedes-Benz GLS-Class, 2024 Mercedes-Benz AMG GT53E. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
