I OWN A 2010 TOYOTA PRIUS..PURCHASED IN AUGUST 2009...CURRENTLY GOING FOR 15K MILES ON THE ODOMETER. I WANT TO REPORT ISSUES WITH SUDDEN ACCELERATION EVEN WHEN I AM STEPPING ON THE BRAKE. I NOTICED EVERY TIME I PASS THRU UNEVEN ROAD, FOR EXAMPLE POTHOLES, ICY ROADS, SNOW. THE MOST COMMON ISSUE I HAVE IS AS I AM GOING DOWN THE ROAD AND CAR HITS A POTHOLE OR MANHOLE (THOSE WITH METAL COVERS) THE CAR WILL SUDDENLY ACCELERATE, ALTHOUGH I AM STEPPING ON THE BRAKE. SOMETIMES I AM AFRAID I WILL HIT THE CAR IN FRONT OF ME, ESPECIALLY WHEN IM IN TRAFFIC. EVEN GOING AT 5-15 MPH, THE CAR WILL ACCELERATE WHEN IT HITS UNEVEN ROAD LIKE POT HOLES OR ICY ROADS. THIS HAS HAPPEN QUITE A FEW TIMES SINCE I PURCHASED THE VEHICLE. JUST YESTERDAY, WE HAD ABOUT 1-2 INCHES OF SNOW. I WAS DRIVING SLOW AND WHEN MAKING A LEFT TURN, THE CAR HIT SOME UNEVEN ROAD AND SNOW AND ACCELERATED WHEN I WAS STEPPING ON THE BRAKE TO MAKE THE TURN. THE CAR WENT UP THE SIDEWALK AND THE BUMPER CRACKED AS IT HIT THE CONCRETE EDGE THAT SEPARATES THE ROAD AND THE SIDEWALK. NO ONE WAS HURT AND NO PROPERTY DAMAGE WAS DONE. THE CAR IS WORKING FINE, BUT THIS SUDDEN ACCELERATION ISSUE IS A MAJOR CONCERN, ESPECIALLY NOW THAT I READ AND HEAR IN THE NEWS THAT 2010 TOYOTA PRIUS ARE BEING REPORTED WITH COMPLAINTS OF SUDDEN ACCELERATION. I THOUGHT MY ISSUE WAS AN ISOLATED CASE. PLEASE TAKE THIS COMPLAINT INTO ACCOUNT. I WILL BE GOING TO THE DEALERSHIP THIS WEEKEND FOR THE 15K SCHEDULED MAINTENANCE AND WILL REPORT THE ISSUE TO THEM. *TR

I OWN A 2010 PRIUS AND TOOK THE CAR INTO THE LOCAL TOYOTA DEALER 2 DAYS AGO FOR THE INITIAL 5,000 MILE CHECK UP TO DISCUSS A COUPLE ISSUES I HAVE FOUND WITH THE CAR. I HAVE EXPERIENCED ON 3 OCCASIONS A FEELING OF BRAKE FAILURE. THIS HAS OCCURRED WHEN I AM DRIVING OVER ROUGH ROAD. WHILE THE BRAKE IS BEING APPLIED IF I HIT BUMPS, THE BRAKE PEDAL DROPS AND I LOSE THE BRAKES. I HAVE IMMEDIATELY LET UP ON THE BRAKE AND THEN REAPPLIED PRESSURE TO THE BRAKE PEDAL TO GET BRAKING BACK. THE DEALER TRIED TO ACHIEVE THE SAME PROBLEM BUT WAS UNABLE TO REPLICATE IT. HE SAID IT WAS JUST THE WAY THE PEDAL MUST FEEL TO ME. OUR DAUGHTERS BOTH HAVE 2006 PRIUS' WHICH I HAVE DRIVEN AND NEVER EXPERIENCED THIS PROBLEM WITH THEIR CAR BRAKES. THE SECOND PROBLEM IS WITH CRUISE CONTROL. AGAIN, I HAVE DRIVEN A 2006 PRIUS AND USED CRUISE CONTROL AND NOT EXPERIENCED THE FOLLOWING IN THE 06 MODEL THAT OCCURS IN OUR 2010 MODEL. THE CAR STARTED TO ACCELERATE IN CRUISE MODE. WE HAVE ALSO FOUND IT TAKES A LOT OF PRESSURE ON THE BRAKE PEDAL TO TAKE IT OUT OF CRUISE CONTROL. THE CAR JERKS WHEN TAPPING THE BRAKE PEDAL LIGHTLY TO TAKE OFF CRUISE CONTROL. THE DEALER AGAIN TOOK IT OUT FOR A TEST DRIVE AND SAID THIS IS THE WAY THE PRIUS FEELS. I KNOW DRIVING THE 2006 MODEL IT WAS NOT THE WAY THE PRIUS FEELS WHEN YOU TAKE IT OUT OF CRUISE CONTROL. *TR

14V053000 · Electrical System:software; Hybrid Propulsion System: Inverter

Feb 12, 2014

Toyota is recalling certain model year 2010 through 2014 Prius vehicles. In the affected vehicles, the Intelligent Power Module (IPM) inside the inverter module (a component of the hybrid system) contains transistors that may become damaged from high operating temperatures. If this occurs, various warning lamps will be illuminated on the instrument panel and the vehicle will have reduced power allowing it to only drive a short distance.

Consequence & remedy

Consequence: The vehicle may enter a fail-safe/limp-home mode that limits the drivability of the vehicle. The hybrid system could also shut down completely resulting in a vehicle stall, increasing the risk of a crash.

Remedy: Toyota will notify owners and dealers will update the software for both the motor/generator control electronic control unit (ECU) and the hybrid control ECU, free of charge. If an owner experiences a failure of the inverter before the vehicle receives updated software, the dealer will repair or replace the inverter assembly with a new one at no charge. The recall began on March 21, 2014. Owners may contact Toyota at 1-800-331-4331.

In support of his request, the petitioner identified 117 NHTSA complaints allegedly related to the subject CSP condition, including 60 reporting crashes. 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.
