What owners reported
Source: NHTSA complaint databaseOwners of the 4 model years this bulletin names have filed 97 complaints with NHTSA since 2015. 7 of them name Power Train — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
I am reporting a recurring transmission/drivability issue with my 2024 Mercedes-Benz S580. The vehicle has been experiencing a harsh, abnormal shift between approximately 3rd and 4th gear at around 25–35 mph during normal acceleration. The shift feels like a sudden jerk or hesitation and does not feel consistent with normal operation.

A complaint is one owner’s account, not a defect finding, and a bulletin is not a recall. Nothing here says this bulletin was issued because of these complaints, or that the repair it describes fixed them. Complaint files on this site begin in 2015.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI07.10-P-077327 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 LI07.10-P-077327 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 LI07.10-P-077327 cover?
The manufacturer filed it against 4 model years: 2024 Mercedes-Benz S-Class, 2023 Mercedes-Benz S-Class, 2022 Mercedes-Benz S-Class, 2021 Mercedes-Benz S-Class. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
