My 2017 has experienced multiple loss of power events( two on the highway!). The vehicles transmission will disengage and I will have to coast to the side of the road. My ignition is still on but have been told previously that my PTU needs replacing. I will have the amber service transmission light illuminated but only after having transmission disengage. This power failure is a extremely serious safety issue- now the local Jeep dealers have no fix and I am having to rent a car because of this safety issue.
