DETROIT -- Chrysler is recalling 45,961 of its Ram 1500 pickups for an electronic stability control problem.

Chrysler says the ESC -- which uses computer-controlled selective braking to help the driver keep control in a too-fast corner or swerve -- in the pickups may not go on when the truck is started. While it is sometimes disabled in special circumstances, it is supposed to be on by default and is generally a safety risk if it is off.

ESC has been required since 2012 on all cars and light-duty trucks.

The recall covers Ram 1500 standard-duty trucks with four-wheel drive that were built from June 26, 2012, through last Feb. 5.

Chrysler says the problem is in the ESC system's software, which will be updated in the recall, and that it has no reports of crashes or injuries linked to the issue.
