I'VE BEEN HEARING IN THE NEWS ABOUT THE POTENTIAL OF A BRAKING ISSUE WITH THE 2010 TOYOTA PRIUS. JUST WANTED TO LET YOU KNOW THAT I DEFINITELY NOTICED THIS ISSUE IN MY NEW PRIUS. APPROXIMATELY ONCE A MONTH, WHEN I'M BRAKING OVER AN UNEVEN OR SLIPPERY SURFACE, ESPECIALLY IF IT IS ONLY ONE SIDE OF THE CAR GOING OVER THE SLIPPERY SURFACE, WHILE I'M BRAKING, THERE IS A MOMENT LASTING LESS THAN A SECOND WHERE IT FEELS LIKE THE BRAKES DISENGAGE. (CAUSES YOUR HEART TO SKIP A BEAT WHEN IT HAPPENS.) I ALSO NOTICED A SEPARATE QUIRK THE OTHER DAY THAT I WANT TO PASS ON TO YOU. I'M NOT SURE IF THIS WAS DONE DELIBERATELY BY TOYOTA OR WHETHER THIS IS A DEFECT, HOWEVER, I BELIEVE MY SPEEDOMETER IS CALIBRATED SO THAT IT READS A SPEED THAT IS 2 MPH FASTER THAN MY ACTUAL SPEED. I NOTICED THIS WHEN I WENT ON A TRIP AND USED MY WIFE'S TOM TOM, WHICH USES ITS GPS SIGNAL TO MEASURE THE SPEED OF THE CAR. THE TOM TOM IS USUALLY SPOT ON IN MY WIFE'S ACURA. IN THE PRIUS, IT WAS INDICATING THAT MY TRUE SPEED WAS 2 MPH LESS THAN WHAT MY SPEEDOMETER INDICATED. I'M WONDERING IF THIS WASN'T SOMEHOW INTENTIONALLY DONE BY TOYOTA TO GET BETTER PERCEIVED GAS MILEAGE BY THE DRIVER. HAVING THE CAR GET OVER THE 50 MPG THRESHOLD IS A BIG MARKETING ADVANTAGE FOR THEM. GETTING OVER THIS THRESHOLD WOULD BE EASIER IF THE ACTUAL SPEED OF THE CAR WAS LESS THAN THE PERCEIVED SPEED. *TW

ALL THREE DRIVERS OF OUR 2010 PRIUS HAVE REPEATEDLY EXPERIENCED THE FOLLOWING BRAKING PROBLEM: IF YOU DRIVE OVER A BUMP, POT HOLE OR MANHOLE COVER WHILE BRAKING NORMALLY AT SPEEDS UNDER 25 MPH, THE BRAKES FEEL AS IF THEY INSTANTANEOUSLY DISENGAGE FOR ABOUT 1 SECOND. NORMAL BRAKING SOON RETURNS, BUT THERE IS A DANGEROUS INCREASE IN BREAKING DISTANCE WHEN YOU NEED IT MOST. WE HAVE IDENTIFIED CERTAIN ROAD LOCATIONS IN OUR AREA WHERE THIS PROBLEM IS REPEATABLE EVEN UNDER DRY ROAD CONDITIONS. THIS PROBLEM HAS RESULTED IN A FEW CLOSE CALLS, BUT SO FAR, NO ACCIDENTS. HOWEVER, I AM ABSOLUTELY CONVINCED THAT A DEFECT SUCH AS THIS WILL RESULT IN SOME DRIVERS HAVING ACCIDENTS. *TW *TR

I WAS DRIVING FROM L.A. TO ROSEVILLE CA ON I-5 NORTH IN MY NEW 2010 TOYOTA PRIUS. BECAUSE I WAS DRIVING AT NIGHT IT WASN'T VERY BUSY AND I HAD THE CRUISE CONTROL ON AT 65 MPH. IN THE DISTANCE I SAW SOME CARS PUSHING THEIR BRAKE PEDALS SO I WANTED TO BRAKE AS WELL A LITTLE TO 1) DEACTIVATE THE CRUISE CONTROL, 2) REDUCE SPEED. PUSHING IT VERY GENTLY, ABSOLUTELY NOTHING HAPPENED. THIS SCARED ME AND I PUSHED HARDER, THEN MY 2010 PRIUS STARTED BRAKING WAY MORE AGGRESSIVELY. I NOTICED ALONG THE WAY AND ALSO AFTER THIS THAT THIS BEHAVIOR IS CONSEQUENT. WHILE DRIVING ON THE HIGHWAY, I CANNOT USE THE BRAKE PEDAL TO RELEASE THE CRUISE CONTROL AND DIMINISH SPEED, BECAUSE NOTHING HAPPENS WHEN YOU PUSH THE BRAKE PEDAL GENTLY, IT TAKES A LITTLE TIME BEFORE IT REACTS. I FIND THIS DISTURBING, BECAUSE IN MY 2000 FORD CROWN VICTORY, EVEN THE VERY SLIGHTEST TOUCH ON THE BRAKE PEDAL ALREADY CAUSES THE CRUISE CONTROL TO TURN OFF AND VERY LIGHTLY DIMINISH SPEED. IN THE PRIUS IN ORDER TO ACHIEVE THIS I HAVE TO PRESS THE BRAKE PEDAL HARD, THEN AFTER SOME DELAY IT STARTS BRAKING FAST. IN THE BEGINNING I THOUGHT THIS IS NORMAL FOR THE PRIUS, BUT I FIND IT QUITE DISTURBING AND SOMETIMES SCARING. HENCE, I MUST TAKE WAY MORE DISTANCE TO CARS AHEAD OF MY ON THE HIGHWAY, BECAUSE I CANNOT BRAKE AS FAST AND STOP AS SOON AS THE OTHER CARS CAN. HONESTLY, IT IS VERY SCARY AND IT MAKES MY FEEL UNSAFE WHILE ON THE HIGHWAY WITH THE PRIUS. I AM DRIVING MY CROWN VICTORIA WHEN I AM DRIVING ON THE HIGHWAY NOW A DAYS. *TW *TR

THIS IS NOT THE SAME 2010 PRIUS BRAKE PROBLEM BEING REPORTED REGARDING TRANSIENT BRAKE FAILURE. WHILE WAITING IN GEAR AT A TRAFFIC SIGNAL WITH FOOT ON THE BRAKE PEDAL, THE PEDAL SLOWLY SINKS ALL THE WAY TO THE MECHANICAL STOP. HOWEVER, THE CAR DOES REMAIN STOPPED EVEN WHEN THE ACCELERATOR PEDAL IS BRIEFLY TAPPED. THE BEHAVIOR IS REPEATABLE AND CONSISTENT. PERSONALLY VERIFIED THAT THERE ARE NO EXTERNAL HYDRAULIC LEAKS. OBSERVED THE FLUID SURFACE IN THE BRAKE FLUID RESERVOIR WHILE AN ASSISTANT SANK THE BRAKE PEDAL. THE SURFACE REMAINED UNDISTURBED, INDICATING THAT THE MASTER HYDRAULIC PISTON IS NOT LEAKY. TOOK IT TO THE DEALER. THE SALES & SERVICE MANAGERS OBSERVED BUT RELUCTANTLY ADMITTED THE BEHAVIOR, TESTED IT ON THEIR COMPUTER AND DECLARED IT ACCEPTABLE. I TESTED A SECOND 2010 PRIUS ON THEIR LOT AND THE BEHAVIOR WAS IDENTICAL. CONSEQUENCES: HAVING DEALT WITH DEALERS BEFORE, WE ARE UNWILLING TO ACCEPT THE DEALER'S REASSURANCE FOR THIS SEEMINGLY UNSAFE BEHAVIOR, AND ARE NOW COMPELLED TO SET THE PARKING BRAKE AT EVERY WAITING STOP. *CN

On September 30, 2019, ODI opened Defect Petition DP19-004 to evaluate the petitioner?s request for an investigation. In August 2020, the petitioner notified the Agency that he was withdrawing his petition. Because the petitioner has withdrawn the petition, we are denying the petition as moot and no further analysis of this petition is necessary.NHTSA is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in the design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Because the petitioner has with withdrawn the petition, the petition is denied as moot. This action does not constitute a finding by NHTSA that a safety-related defect does not exist. The Agency notes that it is not required to receive a defect petition prior to opening a defect investigation and will take further action if warranted by future circumstances.

The subject vehicles are the first model year of a new design generation of the Prius model line.The vehicles are powered by a hybrid drive system that uses both a regenerative braking system, which converts vehicle momentum into electrical energy to be stored in onboard batteries, and a hydraulic brake system more typical of the brake system used on non-hybrid vehicles.As is the case for other similarly designed hybrid vehicles the interaction and management of the two braking systems during ABS braking is complex and requires a sophisticated control system.In a February 9, 2010 Defect Information Report, Toyota advised the agency of its plans to conduct a safety recall to address inconsistent brake feel and increased stopping distances that may occur during braking events requiring ABS operation, such as would occur when braking on rough or low friction road surfaces.Toyota will reprogram the ABS control unit with improved software that addresses this condition.Based on Toyota's action the investigation is closed. ODI will continue to monitor the subject vehicles' performance and will take further action as future circumstances dictate.
