Mercedes-Benz bulletin LI33_30-N-080795
Mercedes-Benz filed this with NHTSA as a service bulletin dated Jul 17, 2026, received Aug 3, 2026, about the power train. It names 7 model years (2019–2025). A service bulletin is not a safety recall: it is the manufacturer telling its dealers how to diagnose or repair a condition, and whether the work is paid for depends on the warranty in force. Quoting the number at a service desk can save a diagnosis.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI33_30-N-080795 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.
