2013 Lexus Ct

TL* THE CONTACT OWNED A 2016 2013 LEXUS CT200. THE CONTACT STATED WHILE DRIVING AT 20 MPH, THE BRAKES LOCKED UP NOT ALLOWING THE BRAKE PEDAL TO BE DEPRESSED. AS A RESULT, THE VEHICLE RAN INTO A TELEPHONE POLE. THE AIR BAGS DEPLOYED. A POLICE REPORT WAS FILED. THE CONTACT SUFFERED A BROKEN COLLAR BONE, BROKEN LEFT HAND, AND A BROKEN FEMUR BONE. THE CONTACT DID RECEIVE MEDICAL ATTENTION. THE VEHICLE WAS NOT DRIVABLE AND WAS TOWED TO A JUNKYARD. THE CONTACT WAS RELATING THIS ISSUE TO THE REPAIRS TO THE LEFT CONTROL ARM PRIOR TO CRASHING THE VEHICLE. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. A DEALER WAS NOT CONTACTED. THE MANUFACTURER HAD NOT BEEN INFORMED OF FAILURE. THE FAILURE MILEAGE WAS 60,000.

ON 9/13/2019 I EXPERIENCED A LOSS OF BRAKING POWER WHILE APPLYING BRAKES ON AN UNEVEN/POTHOLED CITY ROAD SURFACE WHILE APPROACHING A STOP WITH VEHICLES IN FRONT OF ME. THIS LOSS OF BRAKING POWER NEARLY RESULTED IN COLLISION. THE LOSS OF BRAKING POWER HAS HAPPENED NUMEROUS TIMES, BUT UNTIL NOW HAS NOT RESULTED IN A POTENTIALLY HAZARDOUS SITUATION. I DISCOVERED THAT DRIVERS OF BOTH THE CT200H AND PRIUS INDICATE LOSS OF BRAKING POWER WHEN APPLYING BRAKES ON UNEVEN SURFACES SUCH AS POTHOLES, SPEED BUMPS, OR MANHOLES THAT ARE NOT LEVEL WITH THE SURROUNDING ROAD SURFACE. THIS LOSS OF POWER IS OFTEN REPORTED AS ACCELERATION, THOUGH THE MORE LIKELY EXPLANATION (SEE ATTACHMENT) IS THAT DECELERATION IS INTERRUPTED DUE TO SLOW HANDOFF OF REGENERATIVE BRAKING TO FRICTION BRAKING. PREVIOUS REPORTS OF BRAKING ANOMALIES HAVE BEEN FILED WITH NTSB FOR THE LEXUS CT200H, WHICH USES THE SAME REGENERATIVE BRAKING SYSTEM AS THE TOYOTA PRIUS. A DRIVER WHO COLLECTED DATA REGARDING THIS ISSUE STATES: "THE SPEED SENSOR DATA FROM EACH WHEEL ALSO COMES AT ABOUT 60 HZ. ONE WOULD THINK WITH THIS KIND OF DATA RATE THE SYSTEM SHOULD BE ABLE TO ADD IN FRICTION BRAKING FAST ENOUGH (AFTER GOING OVER A BUMP WHILE BRAKING AND REDUCING REGEN BRAKING), SAY IN A SMALL FRACTION OF A SECOND, SO THAT THE DRIVER WON'T HAVE TO EXPERIENCE THE MANY SECONDS OF SENSATION OF LOSS OF BRAKING, IF TOYOTA BOTHERED TO REFINE THE ALGORITHM." A REVIEW OF BRAKING RELATED INCIDENT REPORTS FOR BOTH THE TOYOTA PRIUS AND LEXUS CT200H MAY PROVIDE ADDITIONAL INSIGHT INTO THE FREQUENCY AND SEVERITY OF THE LOSS OF ASSISTED/FRICTION BRAKING ON UNEVEN ROAD SURFACES. SEE ATTACHED ACCELEROMETER DATA.

CAR SURGES WHEN BRAKING AND GOING OVER SPEED BUMP, TRAIN TRACKS, POT HOLES GOING BETWEEN 20 - 35 MILES. THIS HAS HAPPENED ABOUT 5-6 TIMES SINCE WITH 1/14 HAPPENING I HAVE HAD THE CAR. I HAVE ASKED FOR LEXUS OF PALM BEACH TO DO HEALTH CHECK, BRAKE CHECK AND ALL SYSTEMS ARE OK, BUT SOMETHING IS NOT RIGHT. JUST WORRIED THAT WHEN CAR SURGES, ME AND/OR MY FAMILY OR PASSENGERS GET INJURED
