I was traveling on a highway at 65MPH in Hybrid mode. The car displayed a Service Hybrid Electric Vehicle System Warning Message along with several other system failure messages in rapid succession. The battery failure icon was also on. The car lost all power and started slowing down. Luckily traffic was light and I was able to reach a point to where I was able to move to a spot on the roadside. I stopped the car and it automatically went into park and would not move out of park. After several tries I was able to start the vehicle in esave mode and it was running on the ICE. All of the errors cleared. I was able to proceed to a side road and eventually make it home. I took it to my local dealer the next day and a read of the code was a B273C indicating digital crash detection. The service manager said this is a known problem and they are waiting for a fix. Reference Star Publication S2408000063 Rev. C In most cases only the Service Hybrid Electric Vehicle System Warning Message comes on for a few second and gs away. This has occurred on my vehicle multiple times with no side effects. One other time the car went into Turtle mode, which cleared after a restart. It was in town so was not an issue to pull over. This time the loss of power could have been catastrophic if traffic was heavy while traveling on a busy highway at high speeds.
