What’s wrong with it?

An engine stall can increase the risk of a crash. In addition, an engine that overheats can increase the risk of a fire.

Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2021-2023 S580, and Maybach S580 vehicles.

In the event of a mechanical failure in the engine Camtronic system, the engine control unit (ECU) software may cause the engine to overheat or stall.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt. Owners’ complaints are counted on each vehicle’s page.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • How many have been returned or fixed isn’t in the notice.
