While driving the 2013 mks at 70 mph on a 3 lane highway the power cut out and the car began to decelerate. i was able to guide the car from far left lane across 2 additional lanes to shoulder of the road with no power, we coasted. luckily there was light traffic at the time. the car would not restart and a tow truck was called. when our son picked us up roadside he conveyed that the identical problem happened to him in the car. this was approximately a month earlier. i am sure you understand that this created an extremely unsafe condition for us and other drivers. i have contacted the dealership that sold us the car. *ln
The vehicle lost all ability to accelerate while operating at approximately 65 mph on an interstate highway. this forced the operator to coast the vehicle to the shoulder of the highway while navigating through traffic. the powertrain malfunction/reduced power (rtt) wrench symbol illuminated in addition to the service engine soon light. before the tow truck arrived the operator attempted to move the vehicle under its own power every 15 minutes. within approximately 40 minutes the vehicle responded to the accelerator and was driven to the operator's residence. the service technician diagnosed that the throttle body lost electrical power forcing a fail safe mode that disconnected the accelerator control. *tr *js
