Ram is notifying owners of over 340,000 heavy-duty pickup trucks to park outside due to the risk of a fire. The affected vehicles use an older type of heater-grid electrical connector that is no longer in use, according to the Associated Press. A similar recall was performed in 2021, covering a smaller number of trucks. Included in this latest recall are certain 2021-2023 Ram 2500 and 3500 pickups along with Ram 3500, 4500 and 5500 chassis cab models.
