U.S. Auto Regulator Opens Investigation Into Nissan Engine Failures

The U.S. Office of Defects Investigation will be investigating around 454,840 Nissan vehicles due to complaints of engine failure, Reuters reports.

A preliminary investigation was opened into the issue, which has caused a loss of motive power as well as the ability to restart the car. The vehicles in question include the Nissan Rogue, Altima, and Infiniti Qx50 models. The investigation could be expanded if it’s determined to be necessary.

The agency has received six complaints that detail engine failures, loss of power, sounds of engine knocking, metal chunks, and shavings in the oil pan of certain vehicles containing KR15DDT and KR20DDET engines.

In response to the problem, Nissan has turned its focus to potential main bearing and L-link damage or seizures on the engine by implementing changes in various manufacturing procedures.
