What owners reported
Source: NHTSA complaint databaseOwners of the 8 model years this bulletin names have filed 713 complaints with NHTSA since 2015. 20 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.
The contact owns a 2016 Mercedes-Benz GLC 300. The contact stated that while the vehicle was in for routine maintenance, the mechanic discovered severe rusting and corrosion to the rear subframe of the vehicle, near the rear axle area. The cause of the failure was not yet determined, and the vehicle was not repaired.

In May 2023 a black plastic portion of the roof blew off the car. The plastic part that blew off was around the sunroof. There was no wind or blow to the car or anything like that; there was no prior warning or error message; there were no symptoms in advance. The part simply blew off the vehicle.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI68.50-P-079347 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 LI68.50-P-079347 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 LI68.50-P-079347 cover?
The manufacturer filed it against 8 model years: 2023 Mercedes-Benz GLC-Class, 2022 Mercedes-Benz GLC-Class, 2021 Mercedes-Benz GLC-Class, 2020 Mercedes-Benz GLC-Class, 2019 Mercedes-Benz GLC-Class, 2018 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.
