It names 236 model years across Mercedes-Benz and smart (2016–2027).

What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint Clanking noise from the area of the speakers in the doors. Cause Under analysis. Remedy To narrow down the cause, first of all remove the door trim. • If the noise continues to occur even with the door trim removed, then continue the diagnosis working towards the speaker and if necessary, create a TIPS case with an informative video as an attachment. Information: Please refer to this document in the warranty claim and, after completing diagnosis, select the damage code corresponding to the component part that caused the problem. • If the noise stops when the door trim is removed, please proceed in accordance with LI72.10-P-067691. Information: In this case, do not use a damage code for the speakers in the warranty claim!

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.

What owners reported
Source: NHTSA complaint databaseOwners of the 179 model years this bulletin names have filed 4,590 complaints with NHTSA since 2015. 1,155 of them name Electrical System, Structure — 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.
On the 2020 Mercedes-Benz GLE-Class, the 13 owners who gave an odometer reading for Electrical System reported it at a median of 6,615 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
During regular use my 2023, Mercedes Cla 250, had a fault in the instrument display in which the display shut off completely. Only the media display remained on, however the media display is completely useless in this scenario, only the instrument display can show the speed in which the vehicle is traveling and the Rpm range in which the…

I have begun noticing symptoms of the adhesive failing, such as excessive wind noise coming from the front roof area and visible gaps/separation between the panel and the vehicle body. This poses a severe safety risk, as the panel could completely detach while driving and become a high-speed road hazard. No warning lights have appeared.

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 LI82.62-P-078631 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 LI82.62-P-078631 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 LI82.62-P-078631 cover?
The manufacturer filed it against 236 model years across 2 brands (Mercedes-Benz and smart): 2022 Mercedes-Benz A-Class, 2021 Mercedes-Benz A-Class, 2020 Mercedes-Benz A-Class, 2019 Mercedes-Benz A-Class, 2026 Mercedes-Benz AMG GT, 2025 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.
