The National Highway Traffic Safety Administration (NHTSA) has reported a plan to recall more than 200,000 Nissan Titan (above) and Frontier trucks to address a problem that could lead the vehicles to roll away unexpectedly when parked. The problem involves a defective parking pawl, which is supposed to hold the vehicle in park, Nissan said in documents filed with NHTSA. Owners will be notified starting November 1.
