What it saysComplaint: Clattering noise from area of hood with steel suspension. NHTSA’s full summary ↓
Mercedes-Benz filed this with NHTSA as a service bulletin dated Jan 30, 2026, received Sep 4, 2025, about the suspension — 2 documents under this number. It names 19 model years (2022–2026). 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.

What owners reported
Source: NHTSA complaint databaseOwners of the 16 model years this bulletin names have filed 306 complaints with NHTSA since 2015. 1 of them name Suspension — 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.
The steering and suspension system appears to be malfunctioning. The vehicle consistently pulls to the right during normal driving and does not track straight when the steering wheel is held centered. This condition requires constant steering correction and affects vehicle stability and control.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI32.25-P-079706 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 LI32.25-P-079706 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 LI32.25-P-079706 cover?
The manufacturer filed it against 19 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, 2026 Mercedes-Benz CLE-Class and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
