What owners reported
Source: NHTSA complaint databaseOwners of the 14 model years this bulletin names have filed 560 complaints with NHTSA since 2015.
The suspension has failed despite changing engine mounts. It is available for inspection if needed. I also believe there is Premature wear of the front struts and rear shock absorbers. This can affect vehicle handling and control, increasing the risk of a crash.

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 LI32.35-P-079965 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 LI32.35-P-079965 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 LI32.35-P-079965 cover?
The manufacturer filed it against 14 model years: 2026 Mercedes-Benz GLE-Class, 2025 Mercedes-Benz GLE-Class, 2024 Mercedes-Benz GLE-Class, 2023 Mercedes-Benz GLE-Class, 2022 Mercedes-Benz GLE-Class, 2021 Mercedes-Benz GLE-Class and more. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
