The Cummins 6.7L Turbocharger Actuator has failed at 17,809 Miles on this vehicle. Mopar has extended the warranty on this item for 10 years/180,000 miles under Warranty extension 09-001-22 Rev A. They have also extended the warranty on the Ram 2500 & 3500 series vehicles with the same engine and same turbocharger actuator to 15 years/150,000 miles under Warranty extension 09-005-22 Rev. A. The failure of this turbo actuator immediately places this vehicle in ‘limp’ mode, causing an abrupt reduction in speed and hindering its ability to get out of traffic. This vehicle being an emergency response Fire Truck poses an additional risk to the community since it is unable to respond to an emergency. Mopar is telling me that the warranty extension has expired on this item. The manufacture needs to recall these known to fail turbo actuators or at a minimum extend the warranty from 10 to 15 years.
