What owners reported
Source: NHTSA complaint databaseOwners of the 52 model years this bulletin names have filed 2,082 complaints with NHTSA since 2015. 339 of them name Electrical System — 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI82.85-P-076799 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 LI82.85-P-076799 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 LI82.85-P-076799 cover?
The manufacturer filed it against 64 model years: 2021 Mercedes-Benz AMG GT, 2020 Mercedes-Benz AMG GT, 2019 Mercedes-Benz AMG GT, 2018 Mercedes-Benz AMG GT, 2017 Mercedes-Benz AMG GT, 2016 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.
