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 20 model years this bulletin names have filed 765 complaints with NHTSA since 2015. 6 of them name 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.
While driving at 60mph my panoramic sunroof completely shattered. Nothing at all hit the sunroof to cause it to shatter. If my sunshade cover had not been on, the glass would have fallen on me while operating my vehicle. This is not only dangerous but unacceptable. It was also a distraction that could have caused an accident.

While driving on the highway with the panoramic sunroof open, the glass suddenly shattered, sounding like a gunshot or an explosion. Shards of glass flew into the vehicle and rained down on me, creating a very hazardous driving situation. I did not observe any foreign object that could have caused the sunroof to break

The rear lift gate closes unexpectedly when standing behind the vehicle and loading or unloading the cargo area. The keyless soft close activates even though there is no foot movement, or when there is minimal movement. This happens without warning. On several occasions this has happened to me, and also to my wife.

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 LI88.60-P-079592 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 LI88.60-P-079592 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 LI88.60-P-079592 cover?
The manufacturer filed it against 21 model years: 2025 Mercedes-Benz C-Class, 2024 Mercedes-Benz C-Class, 2023 Mercedes-Benz C-Class, 2022 Mercedes-Benz C-Class, 2025 Mercedes-Benz E-Class, 2025 Mercedes-Benz GLC-Class and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
