Consumer Description

While driving at highway speeds, there was a loud pop and the display showed "reduce power mode". We had to improvise a stopping place despite being far from home. There was no warning or issues beforehand. This incident was risky because of the loss of power while on a high speed thoroughfare and limited stopping options. The vehicle required a jump to move onto tow truck to take to dealership, where it has remained for two weeks without an estimate for repair. The symptoms.seem consistent with ICCU failure.
