I OWN A 2004 TOYOTA PRIUS PURCHASED ON MARCH 2ND 2004. APPROXIMATELY 4 MONTHS AFTER ACQUIRING MY VEHICLE I WAS MERGING ONTO THE INTERSTATE WHEN I EXPERIENCED AND ICE ENGINE FAILURE. ALL THE WARNING LIGHTS CAME ON AND I WAS ABLE TO PULL TO THE SHOULDER OF THE ROAD USING THE ELECTRIC MOTOR. SUBSEQUENTLY I REBOOTED THE CAR AND THE ENGINE TURNED OVER. THE NEXT DAY I TOOK THE PRIUS TO A TOYOTA DEALERSHIP. THEY HAD THE CAR FOR SIX DAYS AND APPARENTLY PERFORMED DIAGNOSTICS AND PERFORMED A SOFTWARE FIX. RECENTLY, ON SEPTEMBER 8TH 2005 I EXPERIENCED A 2ND OCCURRENCE OF THE ICE ENGINE SHUTDOWN. THIS SCENARIO OCCURRED WHILE PULLING UP TO A RED LIGHT. AGAIN ALL THE WARNING LIGHTS CAME ON AND THE ENGINE SHUT DOWN. I REBOOTED THE CAR AND TOOK IT TO THE DEALERSHIP FOR SERVICE. THE TOYOTA DEALERSHIP COMPLETED A TSB EG047-04 FOR RECALIBRATING THE ENGINE...

DT: TOTAL BREAKDOWN OF WIFE'S 2004 PRIUS ON SEPTEMBER 2 IN FINE WEATHER ONE IN SAN JOSE. THE VEHICLE DISPLAYED SUDDEN AND SIGNIFICANT LOSS OF POWER WHILE MERGING INTO THE INTERSTATE. LOSS OF GAS/ENGINE POWER WITH FAILURE OF THE INTERNAL COMBUSTION WITH ENGINE TO START, RESULTED IN ONLY ELECTRIC MOTOR PROPULSION AND BREAKDOWN ON THE HIGHWAY AS THE BATTERY QUICKLY WENT TO SINGLE PINK BAR LEVEL WITHIN A 1/2 MILES. MULTIPLE MIL LAMPS LIT UP AND STAYED ON. BEGAN TO MERGE ONTO THE HIGHWAY FROM A STOP SPEED OF 30 OR 40 MPH AND SLOWLY ACCELERATED INTO HEAVY TRAFFIC. SHE HAD TO PULL OFF TO THE (UGH) BREAKDOWN LANE OF THE HIGHWAY WITH ALL OF ITS DEBRIS, ETC. THE DEALER COMPLETED THE REPAIR, SAN JOSE INVOICE NUMBER TOCS190787 DTD 9/2/05 APPLIED EG047-04 ON CAR. THE DEALER REPAIRS SEEMED TO HAVE FIXED THE CAR. CONTACTED A TOYOTA PRIUS ADVISOR WITH THREE...

NOTHING SPECIAL OR EXTRAORDINARY LED UP TO THIS FAILURE. I WAS DRIVING TO WORK AT ABOUT 7:00AM. THE TEMPERATURE OUTSIDE WAS ABOUT 70 DEGREES AND THE CAR IS KEPT IN A GARAGE EVERY EVENING. IN THE MIDDLE OF ACCELERATION (I WAS GOING ABOUT 25MPH), THE CAR STALLED AND THE "RED TRIANGLE OF DEATH" CAME UP ON THE DASH, ALONG WITH SEVERAL WARNING LIGHTS. THE NAVIGATION SYSTEM ALSO PROVIDED THE WORD "PROBLEM" AND A LITTLE, RED CAR SYMBOL WITH AN EXCLAMATION POINT IN THE MIDDLE OF IT WHEN THIS HAPPENED. I WAS ABLE TO DRIVE TO AN APARTMENT COMPLEX UNDER BATTERY POWER ONLY. I THEN SHUT THE CAR OFF, WAITED A FEW SECONDS, AND THEN STARTED IT AGAIN. THE ENGINE DID KICK BACK IN AFTER THIS, BUT THE WARNING SYMBOL (LITTLE, RED CAR) ON THE NAVIGATION SYSTEM DIDN'T GO AWAY. I TOOK THE CAR TO MY TOYOTA DEALERSHIP AND THEY SAID...

1) MY WIFE WAS DRIVING OUR 2004 TOYOTA PRIUS AND THE CAR HAD A WARNING LIGHT TURN ON ON DISPLAY, WENT TO "LIMP" MODE (SLOW) AND SUDDENLY STOPPED AFTER 1/2 MILE. 2) CAR COULD NOT BE CONTROLLED, NO POWER. 3) TOYOTA TOWED CAR TO SHOP AND REPLACED ECU CONTROLLER IN AREA OF FUEL TANK, ECU RELAY AND ENTIRE FUEL TANK ASSEMBLY. PROBLEM HAS NOT HAPPENED AGAIN.

FOR THE SECOND TIME MY 2004 PRIUS HAS STALLED WHILE DRIVING AND SHUT DOWN. I HAVE ATTACHED MY PREVIOUS REPORT TO YOU WHEN IT HAPPED IN MAY 2005. THE FIRST TIME THE ECU WAS REPROGRAMED. THIS TIME I WAS DRIVING ON THE FREEWAY GOING 65 MILES PER HOUR ON JULY 2, 2005 WHEN THE EMERGENCY ENGINE LIGHTS CAME ON ON THE DASH BOARD. THE VEHICLE QUICKLY LOSS POWER BEFORE THE ENGINE SHUT DOWN. THE BATTERY METER CONFIRMED THE LOSS OF RESERVE. I HAD THE VEHICLE TOWED APPROXIMATELY 50 MILES TO MAITA TOYOTA WHERE I HAVE MY PRIUS SERVICE. THE VEHICLE WAS KEEP FROM JULY 2 - 12, 2005. THE SERVICE DEPARTMENT WAS NOT ABLE TO IDENTIFY THE PROBLEM. I PICKED UP THE VEHICLE AND DROVE IT HOME TODAY. NOW I HAVE TO WATCH FOR THE NEXT TIME THAT IT HAPPENS FOR TOYOTA TO RESEARCH THE PROBLEM MORE. A FILE WAS...

WHILE DRIVING AROUND TOWN AND SOME HIGHWAY, INTERMITTENTLY, THE BATTERY CHARGE LEVEL WILL DROP VERY LOW (ONE RED BAR), THE BATTERY WILL NOT CHARGE, AND THE CAR WILL LOOSE POWER. WHEN THE PRIUS HAS POWER LOSS, THE AVERAGE MPG DROPS FROM THE LOW 40'S TO THE LOW 30'S. THE CAR HAS NEVER STALLED AS PER CURRENT INVESTIGATION WITH '04 PRIUS, BUT, THE LOSS OF POWER ALMOST CAUSED AN ACCIDENT. I HAVE TAKEN THE CAR TO A TOYOTA DEALER 3 TIMES, THEY ARE UNABLE TO FIND ANYTHING WRONG WITH THE CAR. HAVE ALSO CONTACTED TOYOTA CORP AND ESCALATED, BUT, THEY MAINTAIN THAT THERE IS NOT A PROBLEM. ALL SOFWARE TECHNICAL BULITENS AND ANY RECALLS HAVE ALL BEEN APPLIED

THEY RESET WARNING LIGHTS, AND TOLD IT WAS SAFE. 2) JUNE 1, 2004, WHILE MERGING ONTO A HIGHWAY GOING UP THE RAMP AT ABOUT 50 MPH CAR JERKED AND SLOWED TO ABOUT 25 MPH WITHOUT WARNING. CAR BEHIND M HAD TO GO ONTO SHOULDER TO AVOID REAR ENDING CONSUMER'S VEHICLE. ALL WARNING LIGHTS WERE ON AGAIN . WHEN CHECKING ENGINE DISPLAY ONLY ELECTRICAL POWER WAS WORKING AGAIN.

DRIVING DOWN THE ROAD AT APPROX 45 MPH IN MY '04 TOYOTA PRIUS. THE VEHICLE LOST POWER AND STALLED IN THE MIDDLE OF THE ROAD. ENGINE STOPPED RUNNING AND BATTERY POWER RAN OUT CAUSING THE VEHICLE TO STALL.

OUR 2004 PRIUS STALLED REPEATEDLY ON A DRIVE FROM HOLLAND, MICH., TO ST. LOUIS, MO, ON DEC. 26/27, 2004. THE FIRST TIME IT HAPPENED, IT WAS AFTER ABOUT AN HOUR OF HIGHWAY DRIVING, WHEN ALL THE DASHBOARD LIGHTS WENT ON AND THE ENGINE DIED. WE WERE ABLE TO COAST OFF THE HIGHWAY. AFTER ABOUT 30 MINUTES ON THE SIDE OF THE ROAD (IT WAS HE DAY AFTER CHRISTMAS AND A SUNDAY, SO HELP WAS NOT READILY AVAILABLE), WE WERE ABLE TO RESTART THE ENGINE AND RETURN TO HOLLAND. THE NEXT DAY, WE TOOK IT TO THE DEALER, WHO COULD NOT FIND ANYTHING WRONG. WE RESUMED DRIVING AND AFTER ABOUT AN HOUR, THE SAME THING HAPPENED. WE PULLED TO THE SIDE OF THE ROAD, WAITED A BIT, AND RESTARTED THE ENGINE. WE REPEATED THIS SEVERAL TIMES, DRIVE, STALL, RESTART, DRIVE, UNTIL WE GOT TO A DEALER IN CHICAGO, WHO DECLARED THAT...

WHILE DRIVING AT 25MPH, 4 TROUBLE LIGHTS LIT UP ON DASHBOARD. AFTER 1-2 MORE MILES, THE ENGINE LOST ALL POWER, DESPITE THE GAS ENGINE STILL RUNNING. THE ELECTRIC SYSTEM SHOWED NO BATTERY POWER. RESTARTING THE ENGINE DIDN'T HELP, AND THE CAR HAD TO BE TOWED.

I WAS DRIVING MY 2004 TOYOTA PRIUS AT APPROXIMATELY 35 MPH WHEN IT SUDDENLY STALLED AND THE ELECTRIC ENGINE POWER DROPPED TO ZERO. I COULD NOT GET THE VEHICLE TO MOVE AND NEEDED TO HAVE IT TOWED TO THE DEALER FOR SERVICE.

I WAS DRIVING ON HIGHWAY 101 NORTH IN A STOP-AND-GO TRAFFIC. I NOTICED THAT THE BATTERY LEVEL CONTINUED TO DROP AND THE GAS ENGINE FAILED TO START TO RECHARGE THE BATTERY. I MANAGE TO SLIDE OUT OF THE FREEWAY AND STOPPED ON THE SHOULDER. I COULD NOT SHUT OFF THE CAR FOR ABOUT 2 MINUTES. I WAS ABLE TO RESTART THE CAR AFTER 5 MINUTES AND THE GAS ENGINE STARTED. THE DISPLAY SHOWED SYMBOLS OF "CHECK ENGINE" AND "HYBRID SYSTEM WARNING" AND A TEXT MESSAGE - "PROBLEM!". I WAS ABLE TO DRIVE TO THE DESTINATION VIA A LOCAL ROUTE.

DT: THE CONTACT OWNS A 2004 TOYOTA PRIUS. THIS VEHICLE WOULD STALL AT HIGH SPEEDS. HE WAS GOING 65-70 MPH AT TIME OF INCIDENT. THIS HAPPENED WITHOUT WARNING. IT EXACTLY WHAT THE REPORTS SAID HAPPENED TO HIM. HE CAN BE CONTACTED BY ODI FOR THIS IF NEEDED. ALSO, HAD PREMATURE WEAR ON TIRES. HAD THE FRONT AND REAR ENDS ALIGNED THREE TIMES SINCE HE PURCHASED THE VEHICLE.*AK

1. I WAS DRIVING AROUND 30 TO 40 MPH AND THE GAS ENGINE FAILED SUDDENLY DURING THE COURSE OF NORMAL DRIVING, LEAVING ONLY THE ELECTRICAL ENGINE RUNNING. AT THE SAME TIME THE ENGINE FAILED, MANY LIGHTS TURNED ON ON THE DASHBOARD. 2. I WAS ON A CANYON ROAD IN THE LOS ANGELES MOUNTAINS WHEN IT FAILED, WHICH WAS A SINGLE LANE ROAD EACH WAY WITH NOWHERE TO PULL OFF. LUCKILY, I HAD JUST REACHED ON OF THE CRESTS IN THE CANYON WHEN THE ENGINE FAILED, SO WITH THE ELECTRICAL ENGINE I WAS ABLE TO COAST TO A SIDE STREET. ONCE ON THE SIDE STREET, THE ELECTRICAL ENGINE DIED QUICKLY, PROBABLY BECAUSE OF THE STEEP SLOPE UPWARDS OF THE STREET. 3. I TRIED TO TURN OFF THE CAR AND IT WOULDN'T TURN OFF, SO I POPPED THE HOOD AND GOT OUT TO SEE IF THERE WAS AN OBVIOUS PROBLEM. FINDING NO...

ON 4/7/05 I WAS TRAVELING ON THE NJ PARKWAY AND ALL OF A SUDDEN FOR NO REASON MY 2004 PRIUS ENGINE STALLED NO GAS TO ENGINE ONLY ELECTRIC POWER THEN THE ELECTRIC POWER SLOWLY IN ABOUT LEST THAN 2 MINUTES WENT TO ZERO AND THEN I HAD TO COAST TO A SAFE SPOT TO PULL OVER ON THE SHOULDER. LUCKILY I WAS ALREADY TRAVELING IN THE SLOW RIGHT LANE, ALTHOUGH AT 5 PM RUSH HOUR ITS STILL GOING 65+ MPH, I COASTED DOWN TO 40 MPH UNTIL I FINALLY CAME TO A SHOULDER IN THE RIGHT LANE. I CHECKED FOR ANYTHING LEAKING NOTHING, AND ABOUT 10 MINUTES LATER IT STARTED UP. NOW ALL WARNING LIGHTS WENT ON THE ENGINE WARNING FAILURE LIGHT WHICH SAID TO BRING TO DEALER RIGHT AWAY WAS ON. I BROUGHT TO DEALER THE NEXT DAY A WAS STILL ABLE TO DRIVE IT. THEY EVENTUALLY FIXED THE...

I HAVE A 2004 TOYOTA PRIUS. I HAVE HAD IT STALL AT LOW SPEED (APPROX 35MPH) MARCH 2004 I HAD IT LOSE POWER AT HIGHWAY SPEED ON NOV 7, 2004.

DT: THE CONTACT OWNS A 2004 TOYOTA PRIUS. THE VEHICLE IS A HYBRID. SHE STATES THAT WHILE DRIVING DOWN THE FREEWAY AT ABOUT 60 MPH VEHICLE STALLED, MAKING IT DIFFICULT FOR HER TO BRAKE OR ACCELERATE. THE DEALER TOLD HER THAT IT WAS A SOFTWARE GLITCH, AND THEY KNEW THAT THEY HAD OTHER PROBLEMS WITH THIS. TOYOTA STATED THAT THEY CONTACTED EVERYONE. HOWEVER THEY DID NOT NOTIFY EVERYONE BECAUSE SHE WAS NOT NOTIFIED. ALSO, THEY DID NOT NOTIFY SOME OF HER FRIENDS, AND THEY DISREGARDED HER TELEPHONE CALLS.*AK

DT: PROBLEMS BEGAN 5-10-05. SEVERAL WARNING LIGHTS APPEARED ON DASHBOARD. THE VEHICLE EXPERIENCED A LOSS OF POWER. THE ELECTRIC MOTOR AND THE BATTERY WERE WORKING CORRECTLY, HOWEVER, THE GAS PORTION OF THE ENGINE WAS NOT WORKING. DEALER REPORTED ECU WAS OUT OF CALIBRATION, AND WAS REPROGRAMMED. VEHICLE IS NOW REPAIRED. DRIVER VISITED A FORUM WHERE SHE NOTICED THERE WAS A REPORT IN THE WALL STREET JOURNAL AND SHE FELT UNSAFE DRIVING VEHICLE.*AK *SB *NM

I OWN A 2004 PRIUS AND ALSO EXPERIENCED A COMPLETE SYSTEM SHUTDOWN WHILE DRIVING ON THE HIGHWAY ABOUT 3 MONTHS AGO. THE ENTIRE GAS ENGINE SHUT DOWN AND ALL WARNING LIGHTS CAME ON. THE ELECTRIC MOTOR REMAINED OPERATIONAL AND ALLOWED ME TO GET OFF THE ROAD AND INTO A PARKING LOT SAFELY. THE DEALER (CABE TOYOTA - LONG BEACH, CA) GAVE ME A BRIEF AND UNSATISFACTORY EXPLAINATION..BRUSHING THIS OFF AS A MINOR PROBLEM SIMILAR TO A COMPUTER NEEDING TO BE RESTARTED. I ASSUME THEY UPGRADED MY SYSTEM BUT STILL FEAR A RECURRENCE IN A LESS CONVENIENT LOCATION. PLEASE LET ME KNOW IF YOU WOULD LIKE ANY ADDITIONAL INFORMATION ON THIS. VEHICLE VIN = [XXX]

OUR 2004 PRIUS ON FOUR SEPARATE OCCASIONS HAD A COMPLETE ENGINE SHUTDOWN WITH LOTS OF INDICATOR LIGHTS LIT ON THE DASHBOARD. THIS HAPPENED TWICE WHILE WE WERE TRAVELING ON INTERSTATE HIGHWAYS IN TRAFFIC AT HIGHWAY SPEEDS, ONCE IN A TOYOTA DEALERSHIP WHILE THE VEHICLE WAS BEING SERVICED, AND ONCE AS WE PULLED INTO A TOYOTO DEALERSHIP FOR SERVICE. WE WERE NOT AWARE WE COULD SEND A COMPLAINT TO NHTSA UNTIL WE SAY TODAY'S MSNBC ARTICLE. THE FIRST ENGINE SHUTDOWN OCCURRED IN THE HYANNIS TOYOTA DEALERSHIP IN MASSACHUSETTS. THEY TOOK QUITE A WHILE TO FIX THE VEHICLE AND MADE SEVERAL PHONE CALLS TO TOYOTA ENGINEERS FOR HELP. THEY WROTE ON OUR RECEIPT: "NEEDS TRANS REPLACEMENT FOR PERMANENT REPAIR." AFTER WE LEFT MASSACHUSETTS WE DROVE ACROSS COUNTRY TOWARD OUR HOME IN CALIFORNIA. THE OTHER THREE ENGINE SHUTDOWNS HAPPENED DURING THIS TRIP. WE HAD TO BE TOWED (AT TOYOTA'S EXPENSE) TWICE AS A...

2004 TOYOTA PRIUS DIED AT 65 MPH ON I-395 CARPOOL LANES. MULTIPLE WARNING LIGHTS FLASHED ON. WAS ABLE TO COAST IT OVER AND RESTART FOR A MILE OR TWO WHEN IT COMPLETELY DIED AGAIN. WAS TOWED TO SPRINGFIELD VA TOYOTA DEALERSHIP WERE IT WAS SERVICED. ERROR CODES C2318 (LOW VOLTAGE ERROR - POWER SUPPLY MALFUNCTION), BATTERY CODE 8442 WERE REPORTED. ALSO, CHECK ENGINE LIGHT ON, FOUND CODE P3791/ENGINE WON'T START. REPROGRAMMED ECU DP0199. CARS SHUTTING DOWN IN HIGH SPEED TRAFFIC IS A CRASH WAITING TO HAPPEN. WE'RE NOT CONVINCED THAT RE-SETTING THE ENGINE CODE IS ENOUGH TO FIX THE PROBLEM. HAS THE ORIGINAL SOFTWARE PROBLEM BEEN LOCATED AND FIXED? DEALERSHIP COULDN'T GIVE US THAT ANSWER.*AK
