The regenerative brake system failed to operate as it normally does, and no indicator lights came on on the dashboard. This unexpected loss of braking force nearly caused me to hit the car in front of me. I had recently disengaged cruise control and was approaching a red light. I pressed my foot on the brake pedal and felt no response from the car. I lifted my foot and pressed again two or three times with no response, neither deceleration nor any change in the regenerative braking meter on the dashboard. I had to press the brake all the way to the floor before the mechanical brakes were activated. This loss of braking power greatly increased my stopping distance and I narrowly avoided hitting the car in front of me. Once the light turned green, I accelerated and tested the brakes again and everything seemed to be working fine, including the regeneration meter. No indicator lights of any kind came on during this incident. This occurred approximately a week ago. I have owned the car for approximately three weeks, and have not experienced any similar issues in the two weeks prior to the incident or in the week since. I have not yet taken it to the dealership as I would not be able to reproduce the issue for them. I will gladly cooperate with any inspection needed to better understand this issue.
This issue is easily repeatable, when braking if you hit a bump (pot hole, etc.) the braking power is greatly reduced & the brake pedal becomes almost impossible to push down to stop the car, making it very hard to stop even when not coming to an abrupt stop.
