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 7 model years this bulletin names have filed 389 complaints with NHTSA since 2015. 1 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.
I was driving and the vehicle began to smoke through the air conditioning vent and within 30 seconds flames of fire entered the vehicle and the vehicle was completely burned. I never received any recall regarding that malfunction and never saw any signal that this would happen. I almost caught in fire due to the imminent flames.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI91-18-N-080032 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 LI91-18-N-080032 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 LI91-18-N-080032 cover?

Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
