Mercedes-Benz bulletin LI32.25-P-079708

What it saysComplaint Metallic clattering/noise from the area of the dashboard on uneven roads Cause A loose upper metal plate in the head bearing (support bushing) causes the noises. NHTSA’s full summary ↓

Mercedes-Benz filed this with NHTSA as a service bulletin dated Sep 4, 2025, received Sep 5, 2025, about the suspension. It names 10 model years (2022–2025). 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 database

Owners of the 9 model years this bulletin names have filed 260 complaints with NHTSA since 2015.

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 579.5

Is Mercedes-Benz LI32.25-P-079708 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-079708 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-079708 cover?

The manufacturer filed it against 10 model years: 2025 Mercedes-Benz C-Class, 2024 Mercedes-Benz C-Class, 2023 Mercedes-Benz C-Class, 2022 Mercedes-Benz C-Class, 2025 Mercedes-Benz E-Class, 2025 Mercedes-Benz GLC-Class and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
