2018 Pacifica 5450 miles - shut off while driving 60 mph on highway
Yesterday I was driving my 2018 Pacifica (non-hybrid, 5450 miles on odometer) using the adaptive cruise control going down the highway at about 60 mph, when suddenly the vehicle quickly lost speed, and the engine had no response to accelerator pedal input. I looked at the dash and it was displaying a message that said to put the vehicle in Park and press the start button. I did not notice if the vehicle was actually idling or if it had shut completely off, but I did not notice a loss of power steering or brakes. I coasted to the shoulder and put the van in park, foot on the brake and pressed the start button. The vehicle started but would only idle at about 600 rpm. The accelerator had no effect on engine RPM and the vehicle could not be shifted out of park. Turned the vehicle off and restarted it several times over about 3 minutes, with the same result. Then I switched off the auto Engine Start/Stop function and was able to immediately start the vehicle as normal. Since then it has run normally. Anyone else have something similar happen to them?
I have reported this to the dealer and have a service appointment scheduled, but since this incident did not produce a fault in the u-connect application and is now running fine, I assume it will be very difficult for them to diagnose. I have also reported it to the NHTSA since this could be a serious safety defect.
