DETROIT (AP) — Toyota is recalling 625,000 Prius hybrid vehicles worldwide because they can stall without warning.

In the U.S., the recall affects 109,000 Prius V wagons from the 2012 to 2014 model years. The Prius V is known as the Prius Plus and Prius Alpha in other markets.

Toyota says the software settings in the hybrid and motor control units could cause them to overheat. If they are damaged, the vehicles will go into a “safe” mode and shut down.

Toyota recalled the Prius sedan last year for the same issue.

Vehicle owners will be notified. Toyota dealers will update the software for free.

Nissan is recalling about 270,000 vehicles worldwide because the ignition start buttons can malfunction and unexpectedly shut down the engine.

The company says the recall covers certain Note, Cube, Juke, Leaf and Venucia e30 vehicles as well as the Serena, March and Micra. Also included are Latio and Versa sedans, and the Sunny, Almera, Tiida. Also the Pulsar and Sylphy sedans, and the eNV200 and NV350 vans. All are mainly from the 2013 and 2014 model years.

In the U.S., the recall affects about 14,600 Versa sedan, Cube and Juke vehicles.

Nissan says the buttons can stick inside a housing when exposed to hot temperatures. If that happens, road vibrations can cause the switches to shut off the engine.

Dealers will replace the housing for free starting in August.
