Editor's note: A previous version of this story incorrectly reported the model years of the Ram 3500 chassis cabs covered by the recall. The error has been corrected.
Fiat Chrysler Automobiles said on Friday it would recall about 228,508 trucks in the United States, Canada, Mexico and some other markets to prevent drivers from unintentionally shifting their vehicles out of "park."
The brake transmission shift interlock (BTSI) may overheat on some vehicles, FCA US LLC said, adding that it would cause the shifter to be repositioned without brake-pedal application, or the presence of a key in the ignition.
The overheating occurs when a driver keeps a foot on the brake while the car is idling in park.
FCA said the recall includes certain 2017-18 Ram 2500 and 3500 pickups; certain 2017-18 Ram 3500, 4500 and 5500 chassis cabs; and 2017-18 Ram 3500 chassis cabs that weigh less than 10,000 pounds. The company also said some 2017-18 Ram 1500 pickups are included in the campaign, "but heavy-duty trucks represent the majority of affected vehicles."
The company said it is unaware of any injuries or accidents related to this recall, which is limited to vehicles equipped with gear shifters on their steering columns.
In December, the company said it would recall about 1.8 million trucks in the United States, Canada, Mexico and some other markets to fix a part that if not operating could allow the driver to shift out of park without depressing the brake pedal.
