What owners reported
Source: NHTSA complaint databaseOwners of the 17 model years this bulletin names have filed 409 complaints with NHTSA since 2015. 3 of them name Air Bags — 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 submitting this report regarding a serious and potentially fatal unintended vehicle acceleration incident that occurred immediately after my vehicle was returned from repair. I originally brought the vehicle to the dealership’s body shop following a collision.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI91.60-P-076303 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 LI91.60-P-076303 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 LI91.60-P-076303 cover?
The manufacturer filed it against 21 model years: 2026 Mercedes-Benz C-Class, 2025 Mercedes-Benz C-Class, 2024 Mercedes-Benz C-Class, 2023 Mercedes-Benz C-Class, 2022 Mercedes-Benz C-Class, 2025 Mercedes-Benz EQS and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
