Mercedes-Benz filed this with NHTSA as a service bulletin dated May 15, 2026, received Sep 10, 2018, about the wheels — 2 documents under this number. It names 126 model years (2016–2026).

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint Noises at the front axle when cornering or maneuvering (video files attached) Note: Save video files locally and play them with Windows Media Player. Cause Driving with summer tires in combination with low outside temperatures. At low outside temperatures or in wet conditions, a noise may be produced at the outer wheel on the front axle while maneuvering with sharp steering angles. Note: AMG vehicles with 4MATIC of model series 217 (without code 494) and model series 222 have a modified axle geometry compared with series production vehicles to provide more sporty handling. The problem cannot be remedied by changing the axle settings.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5.

A PDF link is shown only once NHTSA’s own server has been seen to serve that document; the rest are checked over the following nights. Quote the number at a service desk; it is what the dealer’s system is keyed on.

They brought me into the garage and spun all four tires individually in front of me...Every one of them was no longer a circle, more oval shaped. All four rims lost their shape.

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 LI40.10-P-061032 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 LI40.10-P-061032 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 LI40.10-P-061032 cover?
The manufacturer filed it against 126 model years: 2021 Mercedes-Benz A-Class, 2020 Mercedes-Benz A-Class, 2026 Mercedes-Benz AMG GT, 2025 Mercedes-Benz AMG GT, 2024 Mercedes-Benz AMG GT, 2023 Mercedes-Benz AMG GT and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
