NHTSA Complaint #11413479 — 2010 TOYOTA PRIUS

I WAS JUST TOLD THAT MY 2010 PRIUS NEEDS THE BRAKE BOOST ASSEMBLY (CYLINDER AND BOOST) AT A COST OF $2,570. IT WAS CAUSING MY 4 MONTH OLD, 12V BATTERY TO DRAIN. I THOUGHT THAT WAS OUTRAGEOUS SO I LOOKED INTO IT AND FOUND OUT THERE WAS AN "ENHANCED EXTENDED" WARRANTY ISSUED (NOT A RECALL) , BUT FOR MY VEHICLE IT EXPIRED APRIL 2020. ANOTHER ISSUE THAT I UNCOVERED THAT THIS PART ALSO CAUSES THE PRIUS TO LURCH FORWARD WHEN BRAKING AND YOU HAPPEN TO DRIVE OVER A BUMP. TRAIN TRACKS, OR POTHOLES WHICH IS A SAFETY ISSUE. I HAVE ALSO EXPERIENCED THIS WITH MY PRIUS. FORTUNATELY, I HAVE HAD NO ACCIDENTS SO FAR. I HAVE READ THAT THERE HAVE BEEN ACCIDENTS CAUSED BY THIS ISSUE. TOYOTA SHOULD STEP UP AND FIX THE PROBLEM BEFORE PEOPLE ARE INJURED DUE TO THIS DEFECTIVE BRAKING SYSTEM. MY DAUGHTER DRIVES A 2015 PRIUS. IS ANYTHING MORE BEING DONE? OR ARE THEY GOING TO WAIT UNTIL MORE ACCIDENTS HAPPEN? I STUMBLED ACROSS THIS ISSUE WHEN MY 2010 TOYOTA PRIUS 12V BATTERY REQUIRED FREQUENT JUMP STARTS. I REPLACED THE BATTERY ($300) DEC 2020. PRIOR TO THAT, I CALLED AAA AND GOT A JUMP START. BECAUSE OF COVID, I WASN'T DRIVING THE VEHICLE DAILY (WORK FROM HOME) SO IT WAS ASSUMED THE CAUSE WAS THE VEHICLE SHOULD BE DRIVEN FREQUENTLY.
