NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
After driving the 2025 c300 sedan and leaving it parked for an hour or two, I come back to the car and turn it on. Neither the central screen or drivers screen were operable. The engine, interior lighting, sounds, and other systems were working however all the screens were completely dead.

Common questions
Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz LI82.62-P-079964 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 LI82.62-P-079964 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 LI82.62-P-079964 cover?
The manufacturer filed it against 3 model years: 2025 Mercedes-Benz C-Class, 2024 Mercedes-Benz C-Class, 2023 Mercedes-Benz C-Class. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
