Was driving at approx 20mph on a side road when the car completely lost power and went dead. all the dashboard warning lights lit up at the same time. lost steering control (the steering wheel became very heavy and was unable to steer). managed to coast to a stop a 100 feet away (since the car had absolutely no power). turned off the power button, turned it back on and the car started running again. took it to the dealer the next day. they ran diagnostics, found codes (listed below) which suggested that the smart key lost communication with the car. they kept the car for an extra day, ran the diags overnight just to see if they can reproduce but, was told that they were not able to reproduce the problem. no idea what may have caused the issue. the smart key was sitting on the center console. below are the smart key related codes that were recorded: u0100 - lost communication with ecm/pcm "a" u0142 - lost communication with body control module "b" u0155 - lost communication with instrument panel cluster (ipc) control module u0293 - lost communication with hybrid vehicle control system please help investigate this as this is potentially a very serious issue. by god's grace, there was no other vehicle on the road, was going at a low speed and thank god, this did not happen on a highway at highway speed. thanks.
