2005 TOYOTA PRIUS: IN SLIPPERY CONDITIONS, WHEN A FRONT WHEEL SLIPS, BOTH WHEELS STOP ROTATING AND THEN THE WHEEL THAT DID NOT SLIP IS GIVEN POWER. THIS TAKES ABOUT 1 SECOND. DURING THAT TIME THE MOTOR HAS SHUT DOWN, LOSING SUBSTANTIAL FORWARD MOMENTUM. IF THE SECOND WHEEL SLIPS,THE PROCESS IS REPEATED GIVING THE ORIGINAL WHEEL POWER. THE 1 SECOND TIME INTERVAL OCCURS AGAIN AND MORE FORWARD MOMENTUM IS LOST. ON A SLIPPERY HILL, THIS BASICALLY STOPS THE FORWARD MOTION OF THE AUTO VERY QUICKLY. IF BOTH WHEELS CONTINUE TO SLIP,THE AUTO JUST SITS THERE , WITH THE ELECTRIC MOTOR STARTING AND STOPPING AS THE POWER IS SWITCHED BETWEEN FRONT WHEELS. IF THERE ARE CARS BEHIND YOURS, THEN BACKING UP IS IMPOSSIBLE. IF THE WIFE AND KIDS ARE IN A BAD NEIGHBOR HOOD AND THIS HAPPENS,THAT COULD MEAN REAL TROUBLE. THE CONDITION IS TOTALLY UNACCEPTABLE. ALL THE PRIUS' SHOULD BE RECALLED AND THE TRACTION CONTROL REPROGRAMMED TO ALLOW REDUCED POWER TO THE SLIPPING WHEEL, NOT ZERO POWER. THIS WILL TEND TO MAINTAIN FORWARD MOMENTUM AND KEEP THE MOTOR FROM SHUTTING DOWN. I SPOKE TO THE ORIGINAL DEALER AND THEY CLAIMED NO KNOWLEDGE OF THE DESIGN FLAW. *NM

2005 TOYOTA PRIUS WENT INTO A SUDDEN ENGINE STALLING MODE. I DO REALIZE THAT TOYOTA HAS A RECALL ON SUCH VEHICLES, BUT THE TOYOTA DEALERSHIP THAT I TOOK IT TO, THE SAME PLACE WHERE I BOUGHT THE VEHICLE, THAT HAD A "PRIUS EXPERT" HAS BEEN DIAGNOSING THIS PROBLEM FOR A DAY WITH NO ANSWERS / ANTICIPATED FIX DATE. THIS IS ANNOYING TO SAY THE LEAST, AS TOYOTA DOES NOT SEEM TO HAVE TAKEN THE TIME TO TRAIN IT'S DEALERSHIPS ON THEIR OWN RECALL INFORMATION. I COULD STEER AND OPERATE THE VEHICLE IN ELECTRIC ONLY MODE. PRESSING THE POWER KEY WOULD NOT POWER OFF THE CAR. HENCE THE BATTERY STARTED TO DRAIN. OPENING THE PASSENGER DOOR AND PRESSING THE POWER KEY, SEEMED TO HAVE BEEN ABLE TO STOP THE CAR, NOT SURE WHETHER THIS WAS TIMING, OR SOME COINCIDENCE. STARTING THE CAR AGAIN, MADE THE GASOLINE ENGINE COME ON FOR THE PURPOSE OF REPLENISHING THE CHARGE FOR THE BATTERY, WITH THE DASH STILL DISPLAYING THE SAME ISSUES. ALSO, PRESSING THE ACCELERATOR AGAIN, DOES NOT RAISE THE RPM OF THE GASOLINE ENGINE. ITS STALLING CONTINUES AFTER A POWER CYCLE. *AK

I TOOK MY PRIUS IN FOR RECALL, NOTED IN PE05029, ON OR ABOUT DECEMBER 9, 2005. I HAD NO PROBLEMS WITH THE PRIUS BEFORE THE RECALL BUT DID THE RECALL BECAUSE OF THE PROBLEMS OTHERS WERE HAVING. I HAD 25,000 MILES WITH NO PROBLEMS BEFORE I TOOK THE CAR TO TOYOTA TO DO THE RECALL. SINCE THEN ON TWO OCCASIONS, ON OR ABOUT JANUARY 14, 2006 AND ON OR ABOUT JANUARY 16, 2006, I HAVE HAD THE ENGINE START TO REV UP WHILE AT A STOP LIGHT WITH MY FOOT ON THE BRAKE. I DRIVE USING ONLY ONE FOOT SO THE GAS PEDAL DID NOT HAVE ANYTHING. THE ENGINE SEEMED TO REV TO ABOUT 2000 RPMS. THIS IS AN ESTIMATE ON MY OWN PART FROM THE SOUND AND NOT A MEASUREMENT. ON THE FIRST OCCASION I TURNED OFF THE CLIMATE CONTROL AS I WAS PROCEEDING TO SHUT DOWN THE CAR AND THE ENGINE RETURNED TO NORMAL IDLE AND THEN TURNED OFF AS IT NORMALLY WOULD AT A STOP LIGHT. I LEFT THE CLIMATE CONTROL OFF AND CONTINUED TO DRIVE WHEN THE LIGHT TURNED GREEN AND HAD NO MORE PROBLEMS THAT DAY. ON THE SECOND OCCASION I EASED UP SLIGHTLY ON THE BRAKE PEDAL TO SEE IF THE ENGINE WAS ACTUALLY PROPELLING THE CAR FORWARD AND THE CAR MOVED FORWARD BUT NO STRONGER THAN IT NORMALLY DOES WITH THE ELECTRIC MOTOR. SO, THE ENGINE ALTHOUGH REVVING UP SEEMED TO BE DISCONNECTED FROM THE DRIVE TRAIN. I BELIEVE I NOTICED ON BOTH OCCASIONS THAT THE BATTERY WAS FULLY CHARGES WITH NO WHITE SPACE AT THE TOP AS USUAL. PROBABLY BECAUSE THE ENGINE RUNS MORE ANYWAY SINCE THE RECALL AS CAN BE NOTED BY THE LOSS IN FUEL ECONOMY. I REPORTED IT TO THE DEALERS SERVICE REPRESENTATIVE THAT I TOOK THE CAR IN FOR RECALL AND WAS TOLD THAT UNLESS IT WAS A REPEATABLE PROBLEM THEY PROBABLY WOULD NOT BE ABLE TO FIND ANYTHING. I REQUESTED THAT HE REPORT IT TO TOYOTA ANYWAY. *NM

PURCHASED 2005 TOYOTA PRIUS - VIN # JTD KB2 OU1 530 793 29 ON JULY 20, 2005 -REGISTERED IT TO MY WIFE KRISTA GOTTLIEB. ON JULY 22, 2005 WHEN THIS CAR HAD ABOUT 80 MILES ON IT, I WAS DRIVING IT ON THE HIGHWAY IN TRAFFIC AT ABOUT 50 MPH - WHEN SUDDENLY I LOST COMPLETE POWER. BY THAT, I MEAN THAT THE ACCELERATOR PEDAL WAS COMPLETELY UNRESPONSIVE. I AM NOT AWARE OF WHAT THE INSTRUMENTS INDICATED AS I WAS PREOCCUPIED WITH THE TRAFFIC (FOR MORE DETAILS - I SENT A VERY DETAILED E-MAIL ABOUT THE FAILURE TO OUR DEALER CULLIGAN TOYOTA, AMHERST, NY ON JULY 24, 2005 - I HAVE ALSO SENT ADDITIONAL FOLLOW-UP E-MAILS TO CULLIGAN SINCE THAT DATE. ). AS A RESULT OF THE JULY 24 MESSAGE, I ARRANGED TO LEAVE THE CAR WITH CULLIGAN TOYOTA SERVICE ADVISOR STEPHEN DESOTELL ON WEDNESDAY, JULY 27, 2005 TO BE CHECKED OUT. AT ABOUT 3:00 P.M. ON JULY 27 STEPHEN CALLED ME TO TELL ME THAT THEY HAD CHECKED OUT THE CAR AND COULD FIND NOTHING WRONG WITH IT IN ANY WAY '' MECHANICAL OR COMPUTER OR ANYTHING. HE SAID THAT IT HAD THE LATEST SOFTWARE AND THAT THERE WERE NO OUTSTANDING SERVICE BULLETINS OF RECALLS FOR THE CAR AND THAT IN HIS DISCUSSION WITH TOYOTA, IT WAS SUGGESTED TO HIM THAT I MUST HAVE INADVERTENTLY HIT THE ''POWER'' BUTTON ON THE DASHBOARD - OR WORDS TO THAT EFFECT. SUBSEQUENTLY I TESTED THE CAR AND FOUND THAT I COULD NOT TURN OFF OUR PRIUS BY DELIBERATELY PUSHING OR HOLDING THE POWER BUTTON IN. BY CALL TO THE ABOVE SERVICE ADVISOR SINCE THEN, HE LATER CONFIRMED THAT THIS WAS CORRECT - THAT IT WAS NOT POSSIBLE TO ACCIDENTALLY OR DELIBERATELY SHUT ANY PRIUS DOWN BY HITTING THE POWER BUTTON WHILE THE CAR WAS IN MOTION UNDER POWER. WE HAVE HAD NO REPEAT OF THIS EVENT. HOWEVER, THE FAILURE HAPPENED TO US IN HEAVY TRAFFIC WHEN I WAS IN THE PASSING LANE WITH TRAFFIC ON MY RIGHT AND ONCOMING TRAFFIC ON MY LEFT AND A HIGH-SPEED CAR APPROACHING ME FROM THE REAR - AND I HAD NOWHERE TO STEER TO! IT WAS VERY FRIGHTENING AND WE COULD HAVE BEEN HIT FROM BEHIND. *NM

I HAVE AN EARLY 2005 PRIUS WHICH HAS "STALLED" I.E. LOST AL ENGINE POWER ON TWO OCCASIONS. I BELIEVE THE "STALLING" IS INTENTIONALLY DESIGNED INTO THE SOFTWARE TO PROTECT THE TRANSMISSION. I THINK A DESIGN DECISION INTENDED TO PROTECT THE CAR IS PUTTING MY LIFE AT RISK. MY EARLY 2005 PRIUS HAS "STALLED" TWICE: ONCE ON THE FREEWAY AT 80 MPH WHEN I HAD TO JAM ON THE BRAKES (SOMEONE CUT ME OFF) AND AGAIN ON SURFACE STREETS AT 30 MPH WHEN I FLOORED IT TO ACCELERATE SUDDENLY. IN EACH CASE THE TRANSMISSION'S INTERNAL COMPONENTS WOULD BE UNDER TREMENDOUS STRAIN UNLESS IT DISENGAGED. IN EACH CASE ALL LIGHTS, HEADLIGHTS, INDICATORS STAYED ON, THE "CHECK ENGINE" LIGHT CAME ON, THE CAR CONTINUED COASTING (AS IF PUT IN NEUTRAL), AND THE CAR WAS UNRESPONSIVE TO THE THROTTLE AND THE GEAR SHIFT. (IN NEITHER CASE DID I HIT THE GEAR SHIFT NOR POWER BUTTON BEFORE THE "STALL"). IN BOTH CASES I COASTED TO A SAFE SPOT (TRY CROSSING FIVE LANES OF 70+ MPH FREEWAY TRAFFIC AT NIGHT WHILE COASTING). ONLY AFTER PARKING, TURNING OFF POWER, AND RESTARTING POWER WOULD THE CAR OPERATE...AT WHICH POINT IT OPERATED FINE. DEALER COULDN'T FIND ANYTHING WRONG...IN FACT THE SECOND INCIDENT WAS TWO DAYS AFTER MY 30,000 MILE SERVICE! THEY APPARENTLY TOOK NO ACTION REGARDING THE CONCERN I EXPRESSED TO THE SERVICE REP WITH RESPECT TO STALLING...HE ASSURED ME THEY WOULD CHECK FOR ALL AVAILABLE SOFTWARE UPDATES, BUT CORPORATE TOLD ME TODAY THERE IS AT LEAST ONE UPDATE (RELATING TO THE NAVIGATION SYSTEM) WHICH WAS NOT DOWNLOADED, SO APPARENTLY THE DEALER IS NOT RESPONDING TO THIS LIFE-THREATENING CONCERN. I CALLED CORPORATE TODAY TO START A "CASE" AND WAS TOLD THEY ARE UNAWARE THAT THIS IS A RECURRENT ISSUE. THIS DESPITE DISCUSSIONS IN THE PRESS AND ON HYBRIDCARS.COM. I AM CONTACTING YOU IN CASE I AM KILLED OR INJURED BEFORE TOYOTA FIGURES OUT THAT THIS IS A SERIOUS AND RECURRENT ISSUE. THE FIRST INCIDENT WAS AROUND JANUARY OR FEBRUARY 2005, AND THE MOST RECENT WAS MONDAY SEPT 19 2005. *JB

POSSIBLY RELEVANT TO CURRENT PRIUS SOFTWARE RELIABILITY INVESTIGATION NUMBER : PE05029 I SPOKE TO GILLES LABELLE OF WESTBORO TOYOTA IN WESTBOROUGH MASSACHUSETTS REGARDING THE TOYOTA PRIUS (THIS WAS A PRE-SALES CONVERSATION; I DO NOT AT PRESENT OWN A PRIUS THOUGH UNTIL THIS CONVERSATION I WAS VERY CLOSE BUYING ONE; NOW I FIND MYSELF TAKING A STEP BACK TO ENSURE I'VE DONE MY OWN DUE DILIGENCE). HE MENTIONED THE USE OF A RESET SEQUENCE TO "REBOOT" THE CAR IN THE EVENT OF PROBLEMS AS A WAY TO AVOID THE NEED TO HAVE THE CAR SERVICED; I ASKED HIM HOW OFTEN HE HAD TO REBOOT HIS OWN PRIUS; HE DIDN'T ANSWER DIRECTLY BUT INSTEAD SAID THAT HE HAD HELPED ABOUT 100 CUSTOMERS THROUGH THE REBOOT PROCESS. I AM A OPERATING SYSTEMS SOFTWARE ENGINEER BY PROFESSION AND WAS ALARMED AT THIS "JUST HIT RESET" ATTITUDE TOWARDS SYSTEMS FAILURES; IDEALLY CRASHES IN THE FIELD SHOULD BE RARE ENOUGH THAT EACH ONE CAN BE ROOT-CAUSED, RATHER THAN SHRUGGED OFF. *JB

Status: closed (inferred from source dates) · Electrical System:propulsion System
NHTSA received a petition on or about July 18, 2022, requesting that Federal Motor Vehicle Safety Standard (FMVSS) 141 be applied to all electric and hybrid vehicles operating in the United States. The petition can be reviewed at NHTSA.gov under ODI Number 11486072. FMVSS 141 establishes performance requirements for pedestrian alert sounds for motor vehicles. The standard applies to hybrid and electric vehicles that have a gross vehicle weight rating of 4,536 KG or less or are defined as low-speed vehicles. The standard became fully applicable to all such vehicles manufactured on or after March 1, 2021.On January 27, 2023, NHTSA opened Defect Petition (DP) 22-005 to evaluate the subject matter described in the petition. On June 24, 2023 and as supplemented on June 25, 2023, the petitioner notified NHTSA he was withdrawing his petition. The petitioner indicated that, based on his review of data, there is no justification for asserting potential benefits that could be derived from actions sought by my petition. Based on the petitioner's withdrawal, DP22-005 is closed. Closure of this DP does not represent a determination by NHTSA regarding the subject matter of the petition.

The Office of Defects Investigation (ODI) received a January 2013 defect petition requesting that it open an investigation on Model Year (MY) 2004-2009 Toyota Prius vehicles to address a possible manufacturing safety defect related to the steering column intermediate shaft.During the defect petition evaluation, ODI: 1.Reviewed the petition and its enclosures; 2.Reviewed the subject steering system layout; 3.Examined the Petition Vehicle?s history, including its repair history; 4.Reviewed and followed-up potentially related consumer complaints; 5.Assessed Safety Recalls 06V-188 and 12V-537; and, 6.Requested and examined complaint, claim, field report, service history, and warranty information from Toyota.ODI's review revealed that the petition vehicle had been recalled (Recall 06V188) to remedy a defect in the system identified in the petition with the remedy taking place prior to the failure that prompted the petition. Circumstances point to incorrect reassembly of the petitioner's vehicle by those who performed the recall remedy.ODI examined the issues raised by this petition to identify any related safety defect trend in the general subject vehicle population.That review identified a low rate of related consumer complaints (twenty-five over a eight year period from a population of over 600,000 vehicles) and no pattern that would identify either a safety defect not already covered by the two existing steering safety recalls by Toyota or a systematic problem with either recall remedy.Based on this evaluation, ODI does not believe that additional investigation will lead to a finding that a defect related to motor vehicle safety exists in the subject vehicles. Therefore, in view of the need to allocate and prioritize NHTSA?s limited resources to best accomplish the agency's safety mission, the petition is denied. The denial of this petition does not constitute a finding by NHTSA that a safety-related defect does not exist. The agency reserves the right to take further action if warranted by the circumstances.For more information, see the Federal Register notice in the public file for this action (https://www.nhtsa.gov/recalls#vehicle, select NHTSA ID, enter: DP13001)The ODI reports cited above can be reviewed on-line (https://www.nhtsa.gov/recalls#vehicle) under the following NHTSA ID numbers:10407520, 10418710, 10429551, 10473654, 10478195, 10478053, 10437229, 10489425, 10510722, 10639984, 10648277, 10499778, 10712626, 10723196, 10787530, 10808124, 10838803, 11071646, 11098144, 11099507, 11102659, 11160767, 11192607, 11287550, 11287606

The Office of Defects Investigation (ODI) received a January 2013 defect petition requesting that it open an investigation on Model Year (MY) 2004-2009 Toyota Prius vehicles to address a possible manufacturing safety defect related to the steering column intermediate shaft.During the defect petition evaluation, ODI: 1.Reviewed the petition and its enclosures; 2.Reviewed the subject steering system layout; 3.Examined the Petition Vehicle?s history, including its repair history; 4.Reviewed and followed-up potentially related consumer complaints; 5.Assessed Safety Recalls 06V-188 and 12V-537; and, 6.Requested and examined complaint, claim, field report, service history, and warranty information from Toyota.ODI's review revealed that the petition vehicle had been recalled (Recall 06V188) to remedy a defect in the system identified in the petition with the remedy taking place prior to the failure that prompted the petition.
