SERVICE BRAKES, HYDRAULIC
I BOUGHT A BRAND NEW 2010 TOYOTA PRIUS AND LEFT THE DEALER ON OCTOBER 23, 2009. I HAD TO STOP SHORT AT ONE OF THE STOPLIGHTS ON THE WAY HOME AND NOTICED A DISTURBING LAG BEFORE THE BRAKES ENGAGED. HOURS LATER I WAS DRIVING DOWN A MAJOR HIGHWAY WHEN TRAFFIC STOPPED SUDDENLY AND THE BRAKES WOULD NOT ENGAGE. I REAR-ENDED THE CAR IN FRONT OF ME AND MODESTLY DAMAGED THE CAR I HIT AND SEVERELY DAMAGED MY NEW PRIUS. FORTUNATELY NOONE WAS HURT. MY SIX YEAR OLD SON WAS IN THE BACK SEAT. *TR

VEHICLE SPEED CONTROL
MY NEW 2010 PRIUS ACCELERATED ON IT'S OWN AS I WAS BRAKING AND SLOWLY APPROACHING THE CAR IN FRONT OF ME THAT WAS STOPPED AT A STOP LIGHT QUITE SOME DISTANCE AWAY. MY CAR HAD ALMOST COME TO A COMPLETE STOP WHEN SUDDENLY THE ENGINE REVVED ON IT'S OWN AS MY FOOT WAS STILL ON THE BRAKE. I HAD TO PRESS DOWN SO HARD ON THE BREAK TO KEEP IT FROM SURGING FORWARD THAT THE ABS LIGHT CAME ON AND THEN THE CAR'S REV WENT DOWN ON IT'S OWN AND ALL WAS BACK TO NORMAL AND HADN'T HAPPENED AGAIN SINCE. I BROUGHT THE CAR TO THE DEALER AND THEY KEPT IT FOR TWO DAYS BUT DIDN'T FIND ANYTHING WRONG WITH IT. I HAVE TWO SMALL CHILDREN AND BOUGHT THIS CAR FOR A NUMBER OF REASONS, SAFETY BEING ONE OF THE IMPORTANT ONES. I AM NO LONGER FEELING SAFE. THIS WAS NOT THE FLOOR MATS, OR A SUDDEN STOP MISTAKING ONE PEDAL FOR ANOTHER, OR ANY OTHER FORM OF DRIVER ERROR. THIS WAS THE CAR! PLEASE HELP TO DISCOVER THE CAUSE AND MAKE TOYOTA FIX IT BEFORE SOMEONE GETS HURT OR KILLED. THANK YOU, CHRIS TOPPIN *TR

SERVICE BRAKES, HYDRAULIC
PLEASE INVESTIGATE THE 2010 PRIUS AND ITS' BRAKING SYSTEM. WHILE BRAKING ON A WET PAVEMENT, GOING DOWN HILL OR BRAKING WHEN THE CAR GOES OVER AN UNEVEN OR BUMPY SERVICE, THE CAR ACCELERATES OR LURCHES FORWARD. FORTUNATELY, I WAS A SAFE DISTANCE FROM OTHER CARS OR COULD HAVE HIT SOMETHING WITH THIS SURGE EFFECT. THE CAR ONLY HAS 400 MILES AND THIS HAS OCCURRED AT LEAST 4 TIMES, THE MOST RECENT TODAY ON A HILL WITH WET PAVEMENT AS THE CAR WAS HEADING DOWN HILL. THE BRAKE WAS GENTLY DEPRESSED AND THE CAR SURGED FORWARD. *TR

UNKNOWN OR OTHER
AFTER PUSHING THE POWER BUTTON AND THEN SHIFTING OUT OF PARK TO EITHER DRIVE OR REVERSE, THE VEHICLE LUNGES AND I HAVE TO APPLY THE BRAKE, WHICH MAKES THE VEHICLE JERK. SOMETIMES THE GASOLINE ENGINE STARTS BEFORE I SHIFT INTO GEAR SOMETIMES IT DOESN'T. THIS PROCESS IS REPEATED OVER SEVERAL TIMES FOR A MINUTE OR SO, THEN IT CORRECTS ITSELF. I AM JUST INCHING ALONG LUNGING, BRAKING, JERKING... THIS HAS OCCURRED ABOUT TEN TIMES OVER THE EIGHT WEEKS AND 2540 MILES SINCE PURCHASED AUGUST LL, 2009. TOOK TO DEALER, ON SEPT. 29, 2009; THEY KEPT IT FOR ABOUT 2 HOURS, COULD NOT DUPLICATE AND SAID ALL SYSTEMS CHECKED OUT OK. AT THAT TIME THE PROBLEM HAD OCCURRED ABOUT SIX TIMES. SINCE THAT DATE, THIS CONTINUES TO HAPPEN INTERMITTENTLY. THIS HAS HAPPENED ONLY WHEN IN MY OWN DRIVE OR IN PARKING LOTS. I AM FEARFUL THAT IT COULD HAPPEN ON THE ROAD AND CAUSE AN ACCIDENT AND INJURY TO MYSELF AND/OR OTHERS. THE DEALER AND TOYOTA CASE MANAGER SAY THAT THEY MUST BE ABLE TO DUPLICATE THE PROBLEM BEFORE ANYTHING CAN BE DONE TO CORRECT IT. SINCE IT HAPPENS ONLY ON OCCASION, IT WILL BE DIFFICULT TO DUPLICATE. *TR

VEHICLE SPEED CONTROL, POWER TRAIN
ON THREE OCCASIONS, WHILE DRIVING ON CLEAN, DRY ROAD SURFACES, MY 2010 PRIUS SUDDENLY AND BRIEFLY ACCELERATED WITHOUT ANY WARNING AFTER I DROVE OVER MINOR BUMPS AND, ONE 1 OCCASION, A MANHOLE COVER, WHILE BRAKING. THE SENSATION WAS THAT OF THE ENGINE SUDDENLY SURGING AND ACCELERATING. I WAS FORTUNATELY ABLE TO APPLY HARDER PRESSURE TO THE BRAKE PEDAL, REGAINED CONTROL OF THE VEHICLE AND AVOIDED CRASHING INTO THE CAR IN FRONT OF ME. I SPOKE WITH A TOYOTA FIELD TECHNICAL SPECIALIST TODAY WHO TOLD ME THAT THE MECHANICS OF THE CAR ARE SUCH THAT IF A WHEEL HITS A BUMP OR MOVES ONTO A SURFACE THAT CAUSES IT TO ROTATE AT A DIFFERENT RATE VERSUS THE OTHER WHEELS, THE CAR THINKS IT IS GOING INTO A SKID, AND THE ABS SYSTEM KICKS IN. ALSO, THE SYSTEM THAT GENERATES ENERGY TO RECHARGE THE BATTERY, WHICH ALSO EFFECTIVELY BRAKES THE CAR, SUDDENLY CEASES TO OPERATE. CONSEQUENTLY, YOU HAVE THE SENSATION OF ACCELERATION WHEN IN FACT, ACCORDING TO THE TOYOTA SPECIALIST, THE CAR STOPPED DECELERATING. NONETHELESS, THIS SUDDEN DECELERATION IS UNEXPECTED, AND IF I WAS NOT FOCUSED AT THOSE EXACT MOMENTS AND FAILED TO IMMEDIATELY APPLY SIGNIFICANT PRESSURE TO THE BRAKE PEDAL, I COULD HAVE EASILY CRASHED INTO AN OBJECT, OR CAR, OR PERSON, IN FRONT OF ME. I DO NOT FEEL SAFE IN THIS CAR, AND AM WORRIED THAT MY WIFE OR SON COULD HAVE A MAJOR PROBLEM RESPONDING TO THIS SUDDEN LACK OF CONTROL. THERE IS GREAT POTENTIAL FOR SERIOUS INJURY OR DEATH FROM THIS TYPE OF INCIDENT. MY CAR IS ABOUT 1 MONTH OLD, WITH 1,250 MILES ON IT. I UNDERSTAND FROM THE SPECIALIST THAT TOYOTA DEALERSHIPS ON LONG ISLAND HAVE HAD AT LEAST ONE OTHER SIMILAR COMPLAINT. *TR

ELECTRICAL SYSTEM: INSTRUMENT CLUSTER/PANEL
TL*THE CONTACT TEST DROVE A 2010 TOYOTA PRIUS FROM A AUTHORIZED DEALER. HE STATES THAT HE WAS WEARING POLARIZED SUNGLASSES. HE HAD EXTREME DIFFICULTY READING THE INSTRUMENT PANEL CLUSTER AND SPEEDOMETER GAUGE WHICH EXHIBITED DIM LIGHTING. THE VIN WAS UNAVAILABLE. BL UPDATED 10/09/09 *CN THE CONSUMER STATED THE VEHICLE HAS A DASHBOARD DISPLAY JUST BELOW THE WINDSHIELD THAT REPORTS THE SPEED, FUEL LEVEL AND OTHER OPERATING INFORMATION. THE DISPLAY IS A REFLECTED IMAGE OF A VACUUM-FLUORESCENT DISPLAY INSIDE THE DASH. UNFORTUNATELY, THE REFLECTION PATH POLARIZES THE DISPLAYED IMAGE SO THAT IT IS ALL BUT UNREADABLE THROUGH POLARIZED SUNGLASSES. UPDATED 10/16/09.
