"After driving in electric mode, the fuel pump output may be insufficient to restart the gasoline engine and the vehicle will stall," said NHTSA in its recall summary. "A vehicle stall increases the risk of a crash."
The recall is based on field reports, Mercedes-Benz told federal safety regulators.
No injuries or damages are linked to the recall, the automaker said.
Edmunds says: Owners of these vehicles will be contacted soon by Mercedes-Benz with further instructions on getting their car repaired.
