The following safety recalls were issued Monday by the National Highway Traffic Safety Administration (NHTSA):
- Chrysler is recalling certain 2019-2020 Ram 3500, 4500, and 5500 cab chassis vehicles equipped with a Cummins 6.7L High Output engine. The engine calibration software may not warn about low oil volume. Low oil can damage the engine, causing an oil leak or a punctured engine block, increasing the risk of a fire. NHTSA says potentially 32,002 vehicles are affected by the recall.
- Chrysler is recalling certain 2021 Ram 1500 vehicles equipped with a trailer reverse steering module. The rearview camera image may not display. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, "Rear Visibility." A rearview camera that does not display an image reduces the driver's rear view, increasing the risk of a crash or injury. NHTSA says potentially 14,096 vehicles are affected by the recall.
- Heartland Recreational Vehicles is recalling certain 2018-2021 Mallard, Shadow Cruiser, Sundance XLTTT, Wilderness, Prowler, Trail Runner, 2018-2019 Pioneer, Terry Classic, 2020-2021 Lithium, and 2021 North Trail trailers equipped with a Winntec model 6020 two-stage propane regulator. The regulator may fail, causing an increase in propane pressure. Increased propane pressure can enlarge the flames in gas appliances, increasing the risk of a fire. NHTSA says potentially 22,326 vehicles are affected by the recall.
- Thor Motor Coach is recalling certain 2018-2022 Axis 25.6 and 2018-2021 Vegas 25.6 motorhomes. The heat shield between the LP tank and chassis muffler was not installed. A missing heat shield increases the risk of a fire. NHTSA says potentially 321 vehicles are affected by the recall.
