The company says the recall affects cars from the 2014 model year that were built in Mexico before July 5 and distributed mainly in North America. Nissan says bolts holding the rear seat back latches may not be strong enough. This could increase the injury risk for back-seat passengers in a crash.

Other bolts that secure the body to the undercarriage may not have been tightened enough or could be missing in rare cases. That could weaken the car's rear-crash performance. Nissan says it knows of no crashes or injuries from the problems.

Dealers will check the bolts and fix or replace them. Owners will be notified in mid-August.
