The Nissan Altima, Rogue, and the Infiniti QX50/QX55 are models that have or had the complex variable-compression engine with bearings that could fail. Dealers will inspect the engines, and in cases where it's necessary, they will replace the engine for free.

Nissan is recalling more than 480,000 of its vehicles across the U.S. and Canada due to potential manufacturing defects that could cause engine failure.

Nissan said in its announcement that a failed engine can lead to a “loss of motive power" and increase the risk of a crash.
