It appears a bit of clarity is necessary...
The recall issue is related to a part called the brake transmission shift interlock
, which when functioning properly, disallows a vehicle from moving out of park until the driver steps on the brake pedal. Fiat Chrysler found that in some situations (reported to be extended idle periods while stationary), heat buildup around the gearshift causes the shift interlock to fail.
That means that even if your foot remains on the brake, your truck might move of its own volition. Therefore, the recommended behavior is to always use the parking brake when leaving the truck while it is idling and to ensure that child occupants are never left unattended.
The 1.8 million vehicle recall includes a range of models, including the Ram 1500
, 2500, 3500, 4500, and 5500 pickups from the model years between 2010 and 2017
(of which 1.48 million were sold in the U.S.).
