Mercedes-Benz filed this with NHTSA as an over-the-air update dated Apr 25, 2025, received Apr 24, 2025, about the air bags. It names 27 model years across Mercedes-Benz and Mercedes-Maybach (2022–2024). An over-the-air update is not a safety recall — there is no NHTSA campaign number and no federal requirement — but it is usually work the manufacturer pays for on the vehicles it names; the dealer checks the VIN against the manufacturer’s list.

The electrical systems drains the two batteries after the car sits idle for a few hours. If it can be started, many of the safety features are inoperable until the car is driven for 30 or 40 minutes. I've had it to multiple Mercedes dealers and all they do is re-charge the battery and told me to get a trickle charger.
