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 LI46.80-P-080054 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 LI46.80-P-080054 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 LI46.80-P-080054 cover?
The manufacturer filed it against 11 model years: 2025 Mercedes-Benz CLE-Class, 2024 Mercedes-Benz CLE-Class, 2025 Mercedes-Benz E-Class, 2024 Mercedes-Benz E-Class, 2026 Mercedes-Benz GLC-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.
