## Narrative
I have a 2022 Wrangler 4xe.  This weekend I rear ended a car in stop and go traffic.  When I used the brake it actually felt like the car jumped forward a bit. I had to stomp on the brake pedal again as if my first attempt had no grab.  More details...I was in hybrid mode with <1% battery status and max regen was on.  I was going less than 10 miles an hour.  Jeep has a max regeneration function that uses the engine to generate an EV battery recharge.  I understand that the max regen sort of turns off when you are rolling at really low speeds, but it seems the transition to/from this is rough on the transmission or something. This only happens at low speeds (in parking lots, etc)  This behavior happens intermittently but, this is the first time I was not able to stop completely before an impact occured.
