What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 55 complaints with NHTSA since 2015. 14 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 April 15, 2026 at approximately 1:30 PM PT, I entered my 2023 Mercedes-Benz EQE SUV 500 4MATIC (approximately 20,000 miles) in my garage. The vehicle was not plugged in or charging prior to entry. I opened the car, sat in the driver's seat, and authenticated via the fingerprint scanner.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI54.00-P-077285 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 LI54.00-P-077285 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 LI54.00-P-077285 cover?
The manufacturer filed it against 3 model years: 2024 Mercedes-Benz EQE, 2023 Mercedes-Benz EQE, 2023 Mercedes-Benz Redundant EQE 350 4MATIC. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
