Nissan Motor Co. is recalling 52,016 Titan pickup trucks because their rear seat belts might not adequately protect passengers.
The recall affects the 2016-2017 Nissan Titan Crew Cab and Titan XD Crew Cab pickups. Most of the vehicles are in the U.S., but Nissan said 7,752 are in Canada.
Nissan discovered through testing that a passenger's head could come into contact with part of the rear seat belt assembly in a crash.

Nissan will notify owners and repair the vehicles for free.
