"AUTOMATIC BRAKING SYSTEM FAILED TO ENGAGE" ON A OFFRAMP LANE FROM FREEWAY 5 SOUTHBOUND TO CROWN VALLEY PARKWAY OFF RAMP WHILE TRAVELING APPROXIMATELY 25MPH I REAR ENDED A VEHICLE THAT WAS AT DEAD STOP AND THAT VEHICLE REAR ENDED A SECOND VEHICLE. CALIFORNIA HIGHWAY PATROL WAS CALLED AND REPORT WAS DOCUMENTED WHICH IS ATTACHED. THIS HAPPENED ON DECEMBER 22,2020 AT ABOUT 7PM, DARK CLEAR EVENING IN THE CITY OF MISSION VIEJO. IT WAS ON THE STRAIGHT FREEWAY LANE LEADING TO THE OFFRAMP WITH OTHER LANES ON THE FREEWAY MOVING FREELY. UPON DISCUSSION WITH NISSAN INVESTIGATION (CLAIM NO. 42994813) 615 725 7590, THEY SUMMARIZED 10 PAGE DISCLAIMER FROM OWNERS MANUAL STATING THAT BRAKING SYSTEM IS NOT 100%. ITS UNDERSTANDABLE IF THE VEHICLE WAS OLD BUT THIS IS A NEW VEHICLE WITH WHAT IS ADVERTISED AS A AUTOMATIC BRAKING SYSTEM AND THAT SYSTEM DID NOT WORK. I MANUALLY BRAKED TO A CRASH.
