2010 TOYOTA PRIUS Power Train Problems

The contact owns a 2010 Toyota Prius. The contact stated while driving 45 MPH downhill on a mountain and depressing the accelerator pedal, the pedal travelled down to the floorboard, but the vehicle failed to accelerate as intended. The contact pulled over to the side of the road. The contact stated that upon turning off and restarting the vehicle several times, the vehicle responded as needed. The contact stated that the failure recurred after making a turn at 3-4 MPH downhill. The vehicle was not diagnosed or repaired. The dealer and the manufacturer were notified of the failure. The failure mileage was 194,000.

While driving through the mountains, the ABS, Brake, and Slippery (traction control) warning lights all suddenly illuminated on the dashboard. This happened without any noticeable trigger, and the warning lights remained on for the duration of the drive. I'm concerned about potential issues with the braking or stability systems and request a diagnostic check to ensure everything is functioning properly. Also I am aware that there was recall on Prius 2010 related to ABS system. My VIN was not included in that but seems like similar issue

Purchased new a 2010 Toyota Prius third generation level 4 in July of 2009. Hybrid battery pack failed just after 150,000 warranty lapsed at 155,000 miles. January 2023 floods in Merced, CA damaged one of blocks in Hybrid battery pack driving through waters at 191000 miles on odometer. This threw DTC POA 080 'Check Hybrid System' message. The following month February 2023 at 191500 miles I notice loud cooling fan for hybrid battery operating for the first time ever! Fan is located in rear seat behind front passenger. Air vent is clearly visible. I believe defective fan led to overheating of hybrid battery premature failure at 155,000 miles.

Traveling at freeway speed just after midnight, the "check engine" light came on. Less than one minute later, the "check hybrid system" alert came on, with an exclamation mark inside of a yellow triangle symbol displayed. The vehicle instantly had no power when the accelerator was depressed. The vehicle coasted to a stop and would not shift into drive. The vehicle was towed to our home. Upon delivering the vehicle to our home, the tow driver used an emergency battery jump start device and the vehicle was able to shift into drive and be driven into the garage. The 12 volt battery was replaced the next day and the vehicle no longer exhibited any disfunction. This was an unexpected event with no warning that the 12 volt battery was in need of replacement. It could have resulted in a serious collision, if the freeway had been more congested, as the...

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED WHILE THE VEHICLE WAS PARKED IN HER DRIVEWAY, THE VEHICLE INDEPENDENTLY ROLLED BACKWARDS OUT OF THE DRIVEWAY. AS A RESULT, THE REAR END OF THE VEHICLE RAN INTO A TREE. THE AIR BAGS FAILED TO DEPLOY. A POLICE REPORT WAS NOT FILED.THERE WERE NO INJURIES SUSTAINED. THE VEHICLE WAS ABLE TO DRIVE AND WAS TAKEN TO A COLLISION CENTER. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED AS OF YET. A DEALER WAS NOT CONTACTED. THE MANUFACTURER HAD NOT BEEN INFORMED OF FAILURE. THE FAILURE MILEAGE WAS 173,991. THE VIN WAS NOT AVAILABLE.*DT

CAR SHAKES BADLY WHEN CHANGING FORM ELECTRIC TO GAS MOTOR, STARTED SMOKING IN THE BACK.

TL* THE CONTACT OWNS A 2010 TOYOTA PRIUS. THE CONTACT STATED THAT WHILE DRIVING AT UNKNOWN SPEEDS, THE VEHICLE STALLED WITHOUT WARNING. THE VEHICLE WAS TURNED OFF AND RESTARTED OCCASIONALLY. THE CONTACT RECEIVED NOTIFICATION OF NHTSA CAMPAIGN NUMBER: 18V684000 (HYBRID PROPULSION SYSTEM). THE DEALER WAS NOT CALLED. THE MANUFACTURER WAS NOT MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS APPROXIMATELY 120,000.

WHILE THE CAR IS IN MOTION IT STALLS IN THE ROAD/HIGHWAY AND DOES NOT ACCELERATE. WHEN TAKEN TO THE DEALERSHIP, THEY DIAGNOSE ERROR P08A0 ERROR CODE: REPLACE HYBRID BATTERY PACK.

IT HAS BEEN OVER 2 MONTHS AND NO REMEDY (SOFTWARE UPDATE) HAS BEEN RELEASED FOR NHSTA RECALL # 18V684 (HYBRID SYSTEM MAY SHUTDOWN AND CAUSE STALL J0V). I AM MOVING AND NEED THIS ISSUE FIXED BEFORE I GO OVERSEAS.

I HAVE BEEN EXPERIENCING THE SAFETY RISKS OUTLINED IN THE FOLLOWING MANUFACTURER RECALL NUMBER: J1V NHTSA RECALL NUMBER: 18V684 I HAVE BEEN DEALING WITH THIS ISSUE FOR THE PAST 2 - 3 YEARS AND UNKNOWINGLY MAY HAVE BEEN SPENDING HUNDREDS OF DOLLARS ON REPAIRS THAT MAY NOT HAVE NEEDED TO BE REPLACED. CURRENTLY, MY CAR IS NOT RUNNING AS I EXPERIENCED A STALL (11/09/2018) WHILE EXITING THE FREEWAY AT A HIGH SPEED WITH THE SCREEN READING "CHECK HYBRID SYSTEM" AND THE DASH LIT UP WITH THE YELLOW TRIANGLE AND EXCLAMATION POINT. I AM NOT ABLE TO ACCELERATE DURING THE STALL, BRAKES ARE WORKING. THIS HAS HAPPENED TO ME COUNTLESS TIMES, ALMOST ALWAYS ON THE FREEWAY OR EXITING AND WHILE TRAVELING AT A HIGH SPEED. SOMETIMES THE VEHICLE WOULD START BACK UP AFTER A FEW MINUTES OF BEING TURNED OFF. THIS PARTICULAR TIME (11/09/2018), I COASTED THE VEHICLE TO A SAFE...

THE VEHICLE WAS IN A PARKING LOT. UPON STARTING THE CAR, THE DASH DISPLAYED "CHECK HYBRID SYSTEM" AND THE VEHICLE COULD NOT ACCELERATE ABOVE 25 MILES PER HOUR.

I HAD BEEN DRIVING THE CAR AND HAD EXPERIENCED THE LOSS OF POWER DESCRIBED IN RECENT ARTICLES AS BEING AN INVERTER PROBLEM (THAT WAS THE SUBJECT OF A SOFTWARE UPDATE BY TOYOTA THAT MAY NOT HAVE FIXED THE ISSUE). AFTER EXPERIENCING THIS ISSUE SEVERAL TIMES, MY AUTOBODY SHOP RECOMMENDED REPLACING THE THROTTLE BODY AS THE DIAGNOSTIC CODES WERE NOT 100% CLEAR WHAT THE PROBLEM WAS. I HAVE REPLACED THE THROTTLE BODY AND NOT HAD THE ISSUE SINCE, BUT I THOUGHT I WOULD REPORT THIS JUST IN CASE THIS IS RELATED TO THE INVERTER ISSUE. THE ISSUE I HAD WAS EXACTLY AS DESCRIBED -- DRIVING THE CAR, THEN SUDDENLY LOSING POWER AND PRACTICALLY UNABLE TO MOVE THE VEHICLE (I WAS ABLE TO DRIVE IT MAYBE 3 MPH WITH NO POWER STEERING, BARELY GOT OUT OF AN INTERSECTION IN FRONT OF ONCOMING TRAFFIC ONE TIME IT HAPPENED). THIS HAPPENED AT VARIOUS TIMES,...

HAD RECENTLY PURCHASED THIS VEHICLE USED.. VEHICLE SUDDENLY WAS POWERLESS IN THE MIDDLE OF THE HIGHWAY. STRUGGLED TO COAST TO SIDE OF THE ROAD. BARELY BEING REAR ENDED BY TRAFFIC APPROACHING FROM BEHIND. OVER HEATED INVERTER REPLACED AT NO CHARGE BY TOYOTA DEALERSHIP. THEN DEALERSHIP TRIED TO TELL ME THE CAR NEEDED $5200 IN ADDITIONAL WORK. I AM IN DISBELIEVE I WAS ABLE TO PURCHASE A CAR WITH OUT THIS WORK BEING DONE TO IT.

MY CAR COMPLETELY SHUT DOWN IN TRAFFIC, ENGINE, STEERING, TRANSMISSION ALL QUIT AND I WAS ALMOST IN A HORRIFIC ACCIDENT AS I COULD NOT CONTROL THE CAR OR GET OUT OF ANYONE'S WAY. THE CHECK HYBRID WARNING LIGHT WAS ALSO ON. IT WAS TOWED AND THE GARAGE SAID IT WAS A SOFTWARE UPDATE THAT I WAS NOT MADE AWARE OF THAT CAUSED COMPLETE FAILURE.

OUR PRIUS HAS BEEN LOSING POWER. IT HAS 68K MILES AND WE ARE THE ORIGINAL OWNERS. DRIVING AT HWY SPEEDS WE NOTICED WE HAVE TO PUSH HARD DOWN ON THE GAS JUST TO GET THE CAR TO MAINTAIN HIGHWAY SPEEDS. HILLS ARE EVEN WORSE. WE ARE ALSO STILL WAITING ON THE PARTS TO FIX OUR HEADLIGHTS. OVER THE YEARS I HAVE CHANGED THE LOW BEAM BULBS AT LEAST 6 TIMES! WHEN ARE THE PARTS COMING?

CAR IN TWO ACCIDENTS OVER TWO YEARS BODY WAS NOT PROPERLY WELDED BACK TO THE FRAME! BRAKES WERE NOT PROPERLY REALIGNED NEITHER WAS THE STEERING COLUMN TRANSMISSION BANDS WERE NOT OPERATING AND WOULD NOT SHIFT AND NUMEROUS OTHER PARTS FOR LEAKAGE FROM BRAKE LINES TO TRANSMISSION LINES ALL LINES WERE BROKEN AND SO ARE THE SEALS ON THEM!

WHEN I AM COMING TO A STOP (BRAKING NORMALLY) AND HIT A BUMP, THE CAR SURGES SLIGHTLY AND THE BRAKES BECOME LESS RESPONSIVE. IT FEELS LIKE I'M FIGHTING THE ENGINE AS IT ACCELERATES AND I'M TRYING TO BRAKE AGAINST IT. RELEASING THE BRAKE AND ATTEMPTING AGAIN SEEMS TO BE A SOLUTION, BUT I OFTEN DON'T HAVE TIME BEFORE REACHING THE INTERSECTION I'M APPROACHING. THIS CONSISTENTLY HAPPENS IN TWO PLACES IN MY DAILY COMMUTE WITH A SLIGHT BUCKLE IN THE ROAD APPROACHING AN INTERSECTION ON CITY STREETS AND COUNTY ROADS.

I'VE HAD TWO TOYOTA PRIUS IN MY LIFETIME, A 2005 AND A 2010 TOYOTA PRIUS, BOTH HAVE HAD THE SAME ISSUE WHERE THE ENGINE WOULD EAT UP ALL OF MY OIL, I WOULD HAVE AN OIL CHANGE DONE AND LESS THAN 2 WEEKS LATER I WOULD HAVE TO CHECK THE OIL GAUGE ROD AND FIND THAT THE OIL LEVELS WERE BELOW THE BOTTOM LINE, ALMOST EMPTY! THE ENGINE WOULD BE BURNING OIL AT SUCH AN ALARMING RATE THAT I WOULD REPEATEDLY BRING THE VEHICLE TO TOYOTA FOR OIL CHANGES. I'M VERY UNSATISFIED WITH MY TOYOTA PRIUSES. MY CAR IS CURRENTLY AT 166,384 MILES AND THE ENGINE CYLINDER HAS NOW GIVEN WAY AND ALSO THE HYBRID BATTERY. I'VE GONE ONLY TO TOYOTA DEALERSHIPS TO HAVE PRISTINE CONSECUTIVE SERVICE AND NO THIRD PARTY REPAIR FACILITIES HAVE PROVIDED SERVICE. I AM LOCATED IN SOUTHER CALIFORNIA IN SAN DIEGO. I HAVE SPOKEN TO MANY...

MY 2010 TOYOTA PRIUS IV HAS 98,731 MILES ON IT. THE ENGINE AND POWER TRAIN MALFUNCTIONED DURING A COLD START SO I HAD TO TAKE IT INTO THE TOYOTA DEALER. IT HAD TO BE TOWED TO THE DEALERSHIP ON A FLAT-BED TOW TRUCK BECAUSE THE CAR TRANSAXLE/TRANSMISSION WAS LOCKED IN THE DRIVE POSITION, WOULD NOT GO INTO NEUTRAL, AND THE CAR ENGINE WOULD NOT START REV ABOVE AN IDLE. WHEN I ATTEMPTED TO START IT THE ENGINE ACTED LIKE IT WAS MISFIRING VERY BADLY AND RATTLED VERY BADLY. IT SOUNDED LIKE THE ENGINE WAS NOT GETTING ANY OIL CIRCULATION SO I DIDN'T ATTEMPT ANY MORE COLD STARTS. I COULD NOT GET THE ENGINE INTO NEUTRAL OR ANY OTHER GEAR SO I HAD IT TOWED TO THE DEALERSHIP. WHEN THE CAR WAS AT THE DEALERSHIP I WENT THROUGH MY RECORDS AND FOUND A LETTER TITLED 'WARRANTY ENHANCEMENT PROGRAM NOTIFICATION - ZF3'...

VEHICLE LOST POWER, STALLED WHILE DRIVING AT HIGHWAY SPEED; "CHECK HYBRID SYSTEM" DISPLAYED ON DASH; REQUIRED REPLACEMENT OF INVERTER AND INTELLIGENT POWER MODULE

CAR WOULD NOT DRIVE, OR REVERSE IT SHIFTS TO NEUTRAL SINCE FIRST WEEK I BOUGHT THE CAR IN AUG 2010. I BOUGHT A TOYOTA PRIUS III 2010 (FROM THE DEALERSHIP TOYOTA OF KEARNEY MESA IN SAN DIEGO) IN 2010. THE CAR FROM THE BEGINNING WOULD SHIFT BACK TO NEUTRAL WHEN I SET IT TO DRIVE OR REVERSE. I BOUGHT THE CAR AND AM THE ONLY OWNER). AFTER I ENCOUNTER THIS, WITHIN THE WEEK I TOOK IT TO THE DEALERSHIP WHERE I BOUGHT IT (SAN DIEGO KEARNY MESA) AND THEY TOLD ME THAT IT WAS NOT A PROBLEM. YES, IT WAS A PROBLEM AND THEY REFUSED TO FIX IT. THIS HAS HAPPEN TO MY CAR FROM WEEK 1. NOW 5 YEARS LATER, TODAY, THE CAR WOULD NOT ENGAGE IN "D" OR REVERSE. I TRIED AT LEAST FOR 10 MINUTES. I CALLED A DEALERSHIP NOW IN SEATTLE (SINCE I TAKE MY CAR...

THE VEHICLE RUNS OK AND A FEW MINUTES LATER THE YELLOW TRIANGLE TURNS ON, AS WELL AS THE CHECK ENGINE LIGHT AND THE VEHICLE STARTS TO LOSE POWER. AFTER A FEW MORE MINUTES THE RED STEERING WHEEL LIGHT COMES ON ALONG WITH THE "CHECK HYBRID SYSTEM" MESSAGE AND THE REST OF THE LIGHTS AND THE VEHICLES LOSES ALL POWER AND STOPS. IT WILL NORMALLY TURN BACK ON BUT THERE WAS ONE OCCASION WHERE IT DIDN'T AND MY HUSBAND HAD TO PUSH THE CAR TO A PARKING LOT. I TOOK THE CAR IN ON THE RECALL WHICH SHOULD COVER THIS BUT ALL THEY DID WAS UPDATE THE SOFTWARE AND BLAME THE ISSUE ON A CAR ACCIDENT. I DON'T KNOW IF THIS IS TRUE AS JUST PURCHASED THE VEHICLE BUT IT SOUNDS TO ME THAT THEY COULD HAVE FIXED THE ISSUE UNDER THE RECALL.

I HAD JUST PULLED INTO THE GARAGE AND WAS AT A COMPLETE STOP WHEN THE CAR SURGED FORWARD AND SLAMMED INTO TO THE BACK OF THE GARAGE, I WOULD TIP OVERATTEMPTED TO STOP THE CAR WITH THE BRAKES AND THEY WERE NOT WORKING SO I SHIFTED THE CAR TO REVERSE AND IT SPEED OUT OF THE GARAGE UP AN EMBANKMENT INTO A FENCE. IT. WAS UP ON IT'S SIDE AND I WAS AFRAID THAT IT WOULD TIP OVER SO IN AN ATTEMPT TO BRING IT DOWN LEVEL I SHIFTED TO DRIVE AND IT SPEED OFF FORWARD IT THEN JUMPED A ROW OF BUSHES INTO THE FRONT YARD AND DID A LARGE CIRCLE IN THE FRONT YARD MISSING THREE LARGE PINE TREES AND HITTING A SMALL TREE THAT ENDED UP STOPPING THE CAR AND DEPLOYED THE AIR BAG. *TR

ON 4/24/14 I BROUGHT THE VEHICLE INTO LYNCH TOYOTA IN MANCHESTER, CT IN RESPONSE TO A RECALL TO FIX A PROBLEM WHICH INVOLVED LOSING POWER WHEN ATTEMPTING TO ACCELERATE. THE INVOICE COVERING THE REPAIR INDICATED "SOFTWARE UPDATE FOR MG ECU AND POWER MANAGEMENT ECU AS PER CAMPAIGN EOE". ON 9/29/14 I WAS DRIVING IN MODERATELY HEAVY TRAFFIC ON I-84 IN WEST HARTFORD, CT WHEN I ATTEMPTED TO ACCELERATE TO PASS A SLOW MOVING VEHICLE. AS I BEGAN TO PASS, THE ACCELERATOR SUDDENLY FAILED TO WORK AND THE ENGINE STOPPED AND WOULD NOT RESPOND EVEN THOUGH I CONTINUED TO DEPRESS THE ACCELERATOR, ALTHOUGH I HAD NO POWER THE STEERING WORKED AND I WAS ABLE TO GLIDE TO THE SHOULDER ACROSS THE RIGHT LANE OF TRAFFIC. I TURNED OFF THE ENGINE, RESTARTED IT AND IT HAS FUNCTIONED NORMALLY SINCE. I RETURNED TO LYNCH TOYOTA ON 10/6/14 TO HAVE THE PROBLEM ADDRESSED. THEY...

STOPPED AT RED LIGHT. MADE LEFT TURN. DROVE ABOUT 100 FT. CAR ENGINE STOPPED IN TRAFFIC WITHOUT ANY ACTION ON MY PART. CAR ROLLED FORWARD WITHOUT POWER AND THEN STOPPED. *TR

THE INVERTER IN THE CAR FAILED WHILE ACCELERATING. I ACCELERATED FROM A STOP LIGHT WHILE THE CAR WAS IN POWER MODE. WITHIN A FEW SECONDS, THE CAR LOST POWER, AND I COULD NOT KEEP UP SPEED. THE CAR ENTERED A SAFETY MODE THAT ONLY ALLOWS MINIMAL FORWARD MOVEMENT. A FEW SECONDS LATER, THE CAR WOULD NO LONGER MOVE. BEFORE THE CAR STOPPED, SEVERAL LIGHTS ILLUMINATED ON THE DASHBOARD INCLUDING THE CHECK ENGINE LIGHT AND POWER STEERING LIGHT. "CHECK HYBRID SYSTEM" ALSO APPEARED ON THE DASH. A FEW MONTHS EARLIER, THIS CAR HAD THE SOFTWARE UPDATE OFFERED BY TOYOTA FOR THE COMPANY'S PRIUS RECALL. *TR

MAKING A RIGHT TURN AT 15 MPH AND UPON PRESSING GAS PEDAL TO ACCELERATE AFTER COMPLETING TURN, POWER IS REDUCED TO 'LIMP HOME MODE' AT 10 MPH. CHECK HYBRID SYSTEM MESSAGE APPEARS ON CENTER CONSOLE. 1 MILE LATER THE VEHICLE LOSES ALL POWER AND WILL NOT RESTART. EMERGENCY TOWED TO NEAREST TOYOTA DEALERSHIP. INVERTER ON BACKORDER FROM LOS ANGELES WAREHOUSE AND ESTIMATE IS 3 WEEKS TO REPLACE. RETAIL PRICE OF INVERTER PLUS LABOR AND RENTAL CAR EXPENSES ALL COVERED UNDER WARRANTY IS ABOUT $11,000 USD.

THIS IS A HEADS UP TO OTHER OWNERS OF INVERTER RELATED TO RECALL: RECALL SUBJECT : INVERTER FAILURE MAY CAUSE HYBRID VEHICLE TO STALL REPORT RECEIPT DATE: FEB 12, 2014 NHTSA CAMPAIGN NUMBER: 14V053000 COMPONENT(S): HYBRID PROPULSION SYSTEM. *TR

AFTER DRIVING FOR A COMBINED TIME OF 4 HOURS IN A 5 HOUR PERIOD, MY WIFE LEFT A STORE SHE VISITED OFF ZEBULON ROAD AND I-475 NEAR MACON GA. WHEN ATTEMPTING TO RE-ENTER SOUTHBOUND I-475 THE CAR FAILED AND WOULD NOT ACCELERATE. A FEW SECONDS AFTER THE DRIVE SYSTEM SHUT DOWN AND WOULD NOT RESTART. THE DASH INDICATORS SAID CHECK HYBRID POWER SYSTEM. THE CAR WAS TOWED TO A DEALER ROGERS TOYOTA IN MACON GA, WHERE IT NOW IS. THE DEALER SAYS THAT THE PROBLEM WAS THE ENGINE CONTROL MODULE THOUGH THE INVERTER IS BEING REPLACED UNDER AN EXISTING RECALL ISSUED LAST WEEK. IT IS NOT CLEAR IF THE ENGINE CONTROL MODULE IS COVERED BY THE RECALL. *TR

DRIVING 45 MPH DOWN BUSY 4 LANE STREET WHEN CAR JUST WENT OUT OF GEAR FROM DRIVE TO NEUTRAL AND WOULDN'T GO INTO GEAR. CAR CAME TO A STOP IN HEAVY TRAFFIC AND I WAS ALMOST HIT BY SEVERAL VEHICLES. HAD TO PUSH TO SIDE OF ROAD. CALLED DEALERSHIP AND THEY SENT A TOW TRUCK. THEY SAID THEY HAD NEVER HEARD OF THIS HAPPENING BEFORE BUT WHILE I WAS SITTING THERE WAITING FOR A RIDE I WENT ONLINE AND SAW THAT THIS HAS HAPPENED TO HUNDREDS OF PEOPLE. THE OTHERS AFFECTED BY THIS DEFECT SAID THAT HEAT CAUSES A MAGNET TO DETACH TAKING THE CAR FROM DRIVE TO NEUTRAL. I AM VERY THANKFUL THAT THIS DID NOT HAPPEN ON THE FREEWAY OR COULD HAVE CAUSED FATALITIES. TOYOTA HAS NOT RECALLED ANY VEHICLES OR MADE NOTIFICATION TO OWNERS. THIS IS DANGEROUS AND I'M ONLY PUTTING COMPLAINT IN NOW SINCE I DIDN'T...

DRIVING ON THE HIGHWAY IN ALBANY, NY AREA, SLOWED DOWN TO GO THROUGH TOLLBOOTH AS I BEGAN TO ACCELERATE TO CONTINUE ON HIGHWAY, CHECK HYBRID LIGHT CAME ON AND ENGINE ABRUPTLY STOPPED.

THE INCIDENT OCCURRED WHEN I ATTEMPTED TO ACCELERATE ONTO A TWO-LANE HIGHWAY. BECAUSE OF A SLOW AND SHARP U-TURN WHICH PRECEDES THE SHORT ON-RAMP, I DISABLED THE ECO MODE FOR BETTER ACCELERATION. WHEN I PRESSED DOWN ON THE GAS, THE CAR IMMEDIATELY EMITTED A LOUD SOUND, BECAME UNRESPONSIVE AND WAS UNABLE TO GAIN ADDITIONAL SPEED. EVEN SO, THERE WAS NO OTHER OPTION BUT TO MERGE ONTO THE ROADWAY WHILE DOING NO MORE THAN 30 MPH. IN THE MEANTIME, THE INSTRUMENT PANEL SHOWED A "CHECK HYBRID SYSTEM" MESSAGE ALONG WITH SEVERAL WARNING LIGHTS. I MANAGED TO AVOID ONCOMING TRAFFIC (FROM BEHIND) AND SAFELY PULLED ONTO THE GRASS. ATTEMPTS TO RESTART THE VEHICLE WERE UNSUCCESSFUL WITH THE PREVIOUS MESSAGE REAPPEARING EACH TIME. THE CAR REQUIRED A TOW TO THE NEAREST TOYOTA DEALER. I RECEIVED A CALL FROM THEM THE NEXT BUSINESS DAY, AND THEY EXPLAINED THE CAUSE TO BE A DEFECTIVE INVERTER...

TRUE! GEAR PROBLEM! REMEMBER AIRBUS FLIPPING OUR OF CONTROL WHEN THEY CAME OUT WITH FLY BY WIRE? THE JOY STICK GEAR IS DEFAULT TO SHIFT INTO NEUTRAL WHEN NORMAL PUSH BRING IT IN TO REVERSE. NO WAY TO PUT IT IN NEUTRAL. I THOUGHT THE SAME THING & WAS IN DENIAL UNTIL I REALIZE THAT ITS IMPOSSIBLE TO PUT IT INTO NEUTRAL WHEN THING IS SPEEDING OUT OF CONTROL. DON'T TAKE IT LIGHTLY- I DID BOUGHT A 2010 PRIUS JUST NOW & REALIZE - U CAN'T PUT IT - IN NEUTRAL. I WAS IN DENIAL. ALSO, VENTILATOR FAN SUDDENLY ACCELERATES WHEN U TRY TO SWITCH THE MODES. *DT

I MAY BE ABLE TO HELP WITH YOUR TOYOTA GAS PEDAL PROBLEM. I RENTED A PRIUS OUT IN UTAH A COUPLE OF WEEKS AGO. WHILE TRAVELING THROUGH THE MOUNTAINS, THE CAR SEEMINGLY ACCELERATED UNCONTROLLABLY. I AM A MECHANICAL ENGINEER BY TRADE AND A HABITUAL GEARHEAD. I ALSO DID NOT BUY THE ACCELERATOR STICKING PROBLEM, SO I BEGAN INVESTIGATING THE INCIDENT ON MY OWN. THE SECOND TIME IT HAPPENED, I WAS TRAVELING UP THE SIDE OF A MOUNTAIN IN A NEIGHBORHOOD. THE CAR SUDDENLY LURCHED FORWARD. THE PROBLEM IS ACTUALLY QUITE SIMPLE. THE CRUISE CONTROL IS ATTACHED TO THE STEERING WHEEL AND MOVES WITH THE WHEEL. IF THE CRUISE IS ACTIVATED, SOMETIMES IN A TURN IT IS POSSIBLE TO BUMP THE CRUISE LEVER AND "RESUME" OR "ACCELERATE".
