NHTSA Closes Engine Failure Probe Into 454,840 Nissan Vehicles

The National Highway Traffic Safety Administration said on Monday that it is closing a preliminary evaluation into 454,840 Nissan 7201.T vehicles over engine failure after the Japanese automaker issued a recall in June.

The probe, which was opened in December 2023, alleged that engine failures in certain Nissan vehicles were leading to loss of motive power. Consumers also reported engine knocking noises.

An engine failure could result in a fire if internal components detached and damaged the engine block, creating a hole that allowed engine oil to reach hot surfaces, the U.S. auto safety authority said.

NHTSA said that a total of 1,878 incidents were reported, of which 12 resulted in either crash or a fire.
