Sept 27 (Reuters) - Mercedez-Benz USA is

recalling more than 27,000 vehicles due to a potential risk of

the engine control unit (ECU) software causing the engine to

overheat or stall, the National Highway Traffic Safety

Administration said on Friday.

The recall includes certain Mercedes and Maybach S580 luxury

sedans from years 2021-2023.

An engine stall can increase the risk of a crash and an

overheated engine can increase the risk of a fire, the auto

safety regulator said.

Dealers will update the ECU software free of charge after

the respective owners are notified.
