Source: NHTSA, 49 CFR 579.5Is Mercedes-Benz OTA - 05022025 a recall?
No. A over-the-air update 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.

A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does OTA - 05022025 cover?
The manufacturer filed it against 27 model years across 2 brands (Mercedes-Benz and Mercedes-Maybach): 2024 Mercedes-Benz AMG GT, 2023 Mercedes-Benz AMG GT, 2024 Mercedes-Benz C-Class, 2023 Mercedes-Benz C-Class, 2024 Mercedes-Benz CLE-Class, 2024 Mercedes-Benz EQE and more.
