What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationComplaint The customer may note the following complaints: - The central display may remain dark through the entire drive cycle. The instrument cluster display will remain operational. - No audio is present from the sound system - MBUX multimedia system (A26/17) may not be shown on the initial quick test - Various other MBUX multimedia system (A26/17) related complaints Cause Water ingress through the air vent under the front passenger seat (see attached, note that the vents are facing the rear of the vehicle). As a result, the head unit (A26/17) may become damaged. Inspect the MBUX multimedia system (A16/17) hardware, including all attached wiring and connectors, for traces of water and/or corrosion (see attached picture for example). Remedy Avoid using rubber floor mats for the second row seats on which water can collect and subsequently enter the air vent under the front passenger seat. An optimized cover is now available for the air vent under the front passenger seat (see parts note). To avoid a reoccurrence of water damage, install this cover. Note: Only primary losses resulting from the ingress of fluids that can be attributed to a production error is covered by the warranty. Fluids that are introduced into the vehicle as a result of environmental influences, incorrect repairs or incorrect use by the customer are not covered by the warranty. The damage code specified in this document only applies for the installation of the fan shroud.

Read by machine from the document NHTSA serves (3 pages), read Sep 30, 2026. A part number is shown only where it matches Mercedes-Benz’s own catalogue shape, an operation only with its code and time, and a description only where the reader got it whole; anything it could not settle is left out, and the PDF is the record. Times are the manufacturer’s warranty allowances, not a quote. Listings and prices on eBay Motors are the seller’s.

The summary is NHTSA’s abstract of the document, as filed under 49 CFR 579.5. One communication is usually filed as several documents — the bulletin, a dealer notice, an owner letter — and the number on any of them finds this page. 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 14 model years this bulletin names have filed 562 complaints with NHTSA since 2015. 155 of them name Electrical System, Structure, Equipment — 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.
As I approached a red light and removed my foot from the gas pedal to brake, my dashboard displayed several alarming messages: “Active Brake Assist Functions Limited See Owner's Manual,” “Active Blind Spot Assist Inoperative,” “To Deselect P or N Depress Brake and Start Engine,” and “Traction Control Inoperative See Owner's Manual.”…

The left side of the digital instrument cluster in my 2022 Mercedes-Benz GLE 450 intermittently goes completely blank while driving. When this occurs, I cannot see critical vehicle information, including my speed, fuel level, warning indicators, and other important vehicle functions. The failure happens randomly and without warning.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI82.85-P-071623 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-071623 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-071623 cover?
The manufacturer filed it against 14 model years: 2026 Mercedes-Benz GLE-Class, 2025 Mercedes-Benz GLE-Class, 2024 Mercedes-Benz GLE-Class, 2023 Mercedes-Benz GLE-Class, 2022 Mercedes-Benz GLE-Class, 2021 Mercedes-Benz GLE-Class and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
