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 17 model years this bulletin names have filed 755 complaints with NHTSA since 2015. 54 of them name Fuel/Propulsion 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 2016 Mercedes-Benz Metris, the 22 owners who gave an odometer reading for Fuel/Propulsion System reported it at a median of 35,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
Recently took my vehicle in to get the brakes check and inspected. Technician at Mercedes Benz noticed a fuel leak in the upper fuel line. We both thought was very odd because the vehicle only has 35k miles on it and the line is visibly in great condition. I did a little research and found that there was a recall for this exact issue.

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 LI07.70-N-078824 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 LI07.70-N-078824 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 LI07.70-N-078824 cover?
The manufacturer filed it against 17 model years: 2023 Mercedes-Benz Metris, 2022 Mercedes-Benz Metris, 2021 Mercedes-Benz Metris, 2020 Mercedes-Benz Metris, 2019 Mercedes-Benz Metris, 2018 Mercedes-Benz Metris and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
