In owners' own words
Traveling close to max legal highway speed for the interstate highway I was traveling on. Felt and sounded like two front tires blew and was traveling on the rims (Sparks and sounds and responsiveness on vehicle).
Something in transmission (68RFE) failed and dumps fluid out of the transmission dip stick tube onto the turbo which could cause a fire.
My driver was traveling at 80 MPH in cruise control when he started to notice a vibration from the truck that was shaking the mirrors.

Recalls for the 2012 Ram 3500: 9
Incorrect information in the Service and Owner's Manuals may cause the flanged lug nuts to be over-tightened, which could result in a broken wheel stud and possible wheel separation. Wheel separation can cause a vehicle crash.
A list of the affected trailer models is available at: https://static.nhtsa.gov/odi/rcl/2017/RMISC-17V824-0103.pdf. These extinguishers may become clogged, preventing the extinguisher from discharging as expected or requiring excessive force to activate the extinguisher. If the fire extinguisher does not function properly, it can increase the risk of injury in the event of a fire.
Pushing the brake pedal for prolonged periods when the vehicle is running and in PARK may cause the Brake Transmission Shift Interlock (BTSI) pin to stick in the open position. Being able to shift the transmission without pushing the brake pedal and/or without a key in the ignition can increase the risk of an unintended vehicle rollaway that may result in personal injury or a crash.
The affected vehicles have a 220 amp alternator that may suddenly fail. If the alternator fails, the vehicle may stall without warning, increasing the risk of a crash. There is also the possibility that the alternator may short circuit, increasing the risk of a fire.
These Mopar canvas seat covers were sold through Chrysler dealerships beginning October 15, 2015. The seat covers can impede the deployment of the seat thorax airbags. If the seat cover impedes the air bag deployment, the seat thorax air bags may not provide adequate protection in the event of a crash, increasing the risk of a injury.
The affected vehicles have a steering wheel wiring harness that may rub against the driver air bag module retainer spring. This abrasion may result in an electrical short that could cause driver's frontal air bag to unexpectedly deploy. Inadvertent deployment of the air bag may increase the risk of injury and the possibility of a vehicle crash.
In the affected vehicles, the electrical connectors of the diesel fuel heater may overheat. If the connectors overheat, the fuel heater may leak fuel, increasing the risk of a fire.
The left tie rod assembly may break. A failure of the tie rod assembly may result in a loss of steering control, increasing the risk of a crash.
Due to a loose snap ring inside the transmission, there may be a loss of power transfer through the transmission to the wheels. An unexpected loss of power transfer may increase the risk of a crash.
