NHTSA complaint #11397540 — an unverified report by a vehicle owner.
I AM FACING MANY PROBLEMS WITH MY CAR LATELY; IT OVER HEATS ALOT AND SUDDENLY THE SPEED DROPS WHILE THE CAR IS MOVING IN A VERY DANGEROUS HIGHWAY AND I CAN THEN HARDLY DRIVE IT TO PARK IT ASIDE. A MESSAGE STARTED ALSO TO APPEAR FREQUENTLY "CHECK HYBRID SYSTEM". I WAS INFORMED BY THE OFFICIAL TOYOTA AGENT IN JORDAN (MARKAZIA) THAT THIS PROBLEMS IS CAUSED BY THE INVERTOR. HOWEVER, THEY ARE DENYING THAT THE INVERTOR FOR THIS CAR WAS RECALLED, CONTRARY TO WHAT THE OFFICAL TOYOTA WEBSITE STATES WHEN I ENTER THE VIN. THEY ALSO CALIM THAT THEY ARE OBLIGATED BY THE MAIN OFFICE TO OFFER A SOFTWARE UPDATE ONLY.
NHTSA complaint #11361341 — an unverified report by a vehicle owner.
JUST PURCHASED THE CAR FROM A USED CAR DEALER 8/26/2020 AND WAS DRIVING DOWN A TWO LANE ROAD APPROXIMATELY 45 MPH COMING UP TO A STOP SIGN AND THE BRAKES WENT CRAZY WITH A CONTINUOUS BUZZING SOUND FROM THE BRAKES AND THE DASH ABS, TRACTION CONTROL, BRAKE SYSTEM WARNING LIGHTS ALL CAME ON, WOULD NOT STOP CAUSING ME TO RUN THE STOP SIGN AND MAKE A TURN TO SLOW DOWN AND FINALLY COME TO A STOP. HAD THE TROUBLE CODE READ AND THE STORE READ THE DIAGNOSTIC TROUBLE CODE AS C1391 AND RESET SO I COULD DRIVE THE VEHICLE SLOWLY HOME. I CHECKED FOR RECALLS ON THIS DTC 1391 BUT MY 2010 VIN WAS NOT INCLUDED IN THE RECALL. THEY NEED TO RECALL ALL OF THE 2010 PRIUS.
NHTSA complaint #11351870 — an unverified report by a vehicle owner.
WHILE DRIVING AROUND A CORNER ON CITY STREETS, BRAKING SUDDENLY BECAME VERY DIFFICULT, AND CAUSED THE VEHICLE TO SKID WHEN BRAKES WERE APPLIED. A HIGH-PITCHED ELECTRONIC SQUEAL CAME FROM THE DASHBOARD, AND THE BRAKE SYSTEM LIGHT, ABS LIGHT, VSC LIGHT, AND MASTER WARNING LIGHT ALL TURNED ON. THESE ARE ALL LISTED AS SYMPTOMS OF A FAILED BRAKE ACTUATOR. AFTER CONTACTING A LICENSED TOYOTA DEALERSHIP, I WAS DIRECTED TO THE TOYOTA CUSTOMER CARE DEPARTMENT. AFTER BEING ESCALATED TO A SUPERVISOR, I WAS INFORMED THAT TOYOTA IS AWARE OF THIS PROBLEM, BUT THAT THE WARRANTY EXTENSION THEY USED TO COVER IT EXPIRED IN 2017, AND THEY REFUSED TO COVER THE COST OF REPLACEMENT (~$3000). I BELIEVE THIS ISSUE SHOULD BE CAUSE FOR A SAFETY RECALL, AS IT HAPPENED SUDDENLY AND WITHOUT WARNING WHILE THE VEHICLE WAS IN MOTION. IT WAS PURE LUCK THAT THIS DIDN'T RESULT IN A CRASH.

NHTSA complaint #11343137 — an unverified report by a vehicle owner.
PRIUS HAS LESS THAN 100K MILES AND HAS BEEN RUNNING PERFECTLY. TODAY WHILE DRIVING, THE BRAKE, ABS AND TRACTION CONTROL LIGHTS CAME ON SIMULTANEOUSLY AND BEGAN ALARMING, WHILE SUDDENLY MY BRAKE LOCKED UP. THIS COULD CAUSE ACCIDENT AND INJURY IF IT OCCURRED UNDER THE RIGHT CIRCUMSTANCES. APPARENTLY THERE WAS A PREVIOUS BRAKE BOOSTER RECALL THAT I WAS NEVER NOTIFIED OF AND WHICH HAS SINCE EXPIRED. THIS RECALL SHOULD BE REISSUED TO INCLUDE THE MANY 2010 PRIUSES AFFECTED BY THIS PROBLEM.
NHTSA complaint #11340021 — an unverified report by a vehicle owner.
MY ABS SYSTEM STARTED SHOWING SIGNS OF PROBLEMS, AND I STARTED GETTING CODES FOR ALL SORTS OF BRAKE-RELATED ISSUES. MY BRAKES ENDED UP LOCKING UP AND NOT WORKING, AND MY BATTERY IN MY CAR DIED BECAUSE IT WAS THE BRAKE SYSTEM WAS NOT ABLE TO RECHARGE MY BATTERY. EVEN THOUGH I STARTED HAVING ISSUES WITH IT IN FEBRUARY, APPARENTLY TOYOTA SAID THAT BECAUSE I HAD A 2010 PRIUS, THAT SINCE NOVEMBER 31, 2019 HAD PASSED, THE RECALL/EXTENDED WARRANTY "RAN OUT" ON IT. EVEN THOUGH THIS IS A PROBLEM THAT OBVIOUSLY WASN'T FIXED IN THE FIRST PLACE. SO WHEN I TOOK IT TO THE DEALERSHIP TO GET A DIAGNOSTICS RAN ON IT, THEY SAID THAT THEY NEEDED $3,200 TO FIX THE VEHICLE. THIS INCLUDED BOTH THE PURCHASING AND INSTALLATION OF A NEW BRAKE BOOSTER/MASTER CYLINDER ASSEM AND AN ABS PUMP MOTOR ASSEM. I OBVIOUSLY DO NOT HAVE THE MONEY FOR THE REPAIR AND THEY ARE TELLING ME TO GO KICK ROCKS. THIS IS NOT RIGHT AND BECAUSE OF THE BRAKE ISSUE NOT BEING FIXED IN THE FIRST PLACE, IT THEN ALLOWED MY BATTERY (WHICH RUNS AROUND $1,500) TO GET COMPLETELY DRAINED AND PREVENTED IT FROM BEING PROPERLY RECHARGED BY THE BRAKE SYSTEM.
NHTSA complaint #11330449 — an unverified report by a vehicle owner.
I BROUGHT MY TOYOTA PRIUS TO TOYOTA DEALER AS ABS ALERT WAS ON AND I LOST CONTROLLING THE BRAKE. TOYOTA DEALER GAVE ME AN ESTIMATE FOR REPAIR AT $2,850.00 ( P1391 ABNORMAL LEAK IN ACCUMULATOR PUMP REC MASTER CYLINDER WITH BRAKE BOOSTER AND BRAKE BOOSTER PIMP ASSEMBLY) DUE WARRANTY ENHANCEMENT EXPIRED 05.09.2020 OR 150,000,MILES. I'VE GOT ABS ALERT IN THE BEGINNING OF MAY'20, HOWEVER, DUE TO COVID-19 STAY-HOME ORDER, I HAD TO STAY HOME AND WON'T ABLE TO BRING MY CAR UNTIL END OF MAY, .2020. I WAS ADVISED BY TOYOTA DEALERSHIP TO CONTACT TOYOTA CUSTOMER RELATION AS THEY MAY CONSIDER TO EXTEND THE WARRANTY, SO I CONTACTED TOYOTA CUSTOMER RELATION( ACTUALLY I WAS TRANSFERRED TO FINANCIAL DEPARTMENT) AND THEY DENIED TO EXTEND THE WARRANTY, AND THEY REPEATED AS " WARRANTY IS WARRANTY" . I WAS VERY DISAPPOINTED WITH TOYOTA'S UNKIND DECISION AND SERVICE UNDER COVID-19 SITUATION. I READ TOYOTA 2010 HAS PROBLEMS OF BRAKE ISSUES, SO I WANT TOYOTA TAKE A RESPONSIBILITY TO FIX MY BRAKE PROBLEM.

PRIUS STALLS IN THE RAIN DESPITE NOT BEING A RECALLED MODEL. PCS SENSOR IS AFTERMARKET, PEDESTRIAN WARNING ALERT NOISE IS OFFLINE, SUSPENSION IS CRACKED, ENGINE MAKES CREAKING NOISE AT LOW SPEED TURNING. I WORKED FOR TOYOTA AS A SALESPERSON AND THEY REALLY TOOK ADVANTAGE OF ME.
NHTSA complaint #11327502 — an unverified report by a vehicle owner.
BRAKES AND VDC SYSTEM CONSTANTLY ENGAGE DURING U-TURNS, TIGHT TURNING CIRCLES, CAUSING THE CAR TO BRAKE UNEXPECTEDLY. WHILE NOT ACCIDENT HAS HAPPENED, IT HAS CAUSED A FEW NEAR MISSES AS MY WINDOW TO TURN SHRINKS BECAUSE THE CAR IS BRAKING.
NHTSA complaint #11326958 — an unverified report by a vehicle owner.
PROXIMITY SENSORS GENERATED AN ALERT THAT PARKING ASSISTANCE SENSORS NEEDED CLEANING DURING MODERATE RAIN CLEANING THE SENSORS DID NOT RESOLVE THE ISSUE. STOPPED AT DEALER TO HAVE IT CHECKED AND WAS ADVISED THAT THE SENSOR DO THAT IN INCLEMENT WEATHER AND I WOULD NEED TO LEARN TO LIVE WITH IT. IF IT WAS JUST THE PARKING SENSORS IT WOULD NOT BE AS SIGNIFICANT BUT I DID DETERMINE THE FRONT ACCIDENT ASSISTANCE DID NOT FUNCTION AS IT SHOULD HAVE - AS I APPROACHED A VEHICLE IN FRONT OF ME WITH CRUISE CONTROL THE SPEED REDUCTION THAT WAS SUPPOSED TO OCCUR DID NOT HAPPEN. HAD I NOT BEEN CHECKING TO SEE WHAT WOULD HAPPEN IF THE PROXIMITY SENSORS WERE MALFUNCTIONING IT COULD HAVE RESULTED IN AN ACCIDENT. I DID NOT ATTEMPT ANY OTHER ACTIONS WHICH RELY ON PROXIMITY SENSORS TO FUNCTION AS I DID NOT WANT TO CAUSE OR BE INVOLVED IN AN ACCIDENT. I WAS DRIVING AT THE TIME AND I EXPECT THAT ALTHOUGH THE ALERT SPECIFICALLY MENTIONED PARKING SENSORS, THE FACT THAT THE CAR DID NOT SLOW AS TOYOTA HAS INDICATED IT SHOULD LEADS BE TO BELIEVE THAT ANY AND ALL "DRIVER ASSISTANCE TECHNOLOGIES" MAY FAIL WHEN THAT ALERT OCCURS RESULTING IN POTENTIAL ACCIDENTS AND INJURIES THE VSC OFF INDICATOR WAS FLASHING AT THE TIME.
