since new collision avoidance/other safety features will just shut off was in for service several times to correct problem finally jeep got involved for latest software update 4 days later system failed again set up another appt with jeep/dealer unfortanetley vehicle was involved in collision with school bus prior to appointment. i could sometimes be able to turn system back on thru touch screen and sometimes would not allow function to be reset i had reset feature after last failure but it failed again and as previous just randomly while traveling had system been functioning as intended it would have avoided this collision
