2004 Toyota Prius complaints

THE CAR STALLED WHILE COMING TO A STOP AT A TRAFFIC LITE. WARNINGS LIGHTS ON INCLUDED: VSC,ENGINE WARNING LITE. CAR RESTARTED AND WENT ABOUT 500 FT. GOING ABOUT 35 MPH AND STALLED AGAIN. COASTED TO BERM, CALLED DEALER, WHO SAID IT WAS DRIVEABLE TO DEALERSHIP. STARTED OUT ON I295, WENT UP TO 48 MPH AND ENGINE STOPPED. COASTED TO SIDE OF ROAD AND WAS TOWED TO DEALER. DEALER KEPT CAR OVER A WK, SAID SINCE BATTERY WAS DEAD, CHIP HAD NO INFO. THEY FOUND NOTHING WRONG WITH THE CAR AND RETURNED IT TO ME.

I WAS TRANSITIONING BETWEEN TWO FREEWAYS IN MY 2004 TOYOTA PRIUS AND HAD STARTED BRAKING/DECELERATING FOR A LOOMING TRAFFIC JAM UP AHEAD WHEN THE GAS ENGINE STALLED AND ALL DASH WARNING LIGHTS CAME ON, ALONG WITH THE NAV SYSTEM SCREEN SAYING "PROBLEM" AND A RED CAR ICON. MY SPEED COULD HAVE BEEN ANYWHERE BETWEEN 70MPH AND 35MPH AT THE TIME OF THE STALL. THE ELECTRIC MOTOR WAS STILL FUNCTIONAL, SO I EXITED THE FREEWAY, PARKED THE CAR, POWERED IT OFF, THEN POWERED IT BACK ON. THE RED TRIANGLE OF DEATH WAS STILL LIT ON THE DASH, AS WELL AS THE ENGINE CHECK LIGHT, BUT THE GAS ENGINE WAS NOW OPERATING NORMALLY AND WAS RECHARGING THE ALMOST-DEPLETED ELECTRIC DRIVE BATTERY. I WAS ABLE TO DRIVE HOME WITHOUT ANY FURTHER INCIDENT. THE NEXT DAY, I TOOK MY CAR INTO TOYOTA OF HUNTINGTON BEACH FOR REPAIR, AND THEY "REPROGRAMMED [THE] ELECTRONIC CONTROL MODULE". MY SYMPTOMS SEEM RELATED TO THE PE05029 DEFECT INVESTIGATION AND THE NHTSA ODI COMPLAINTS OF OTHER PRIUS DRIVERS. THIS DESPERATELY NEEDS TO BE A RECALL ITEM BECAUSE A SUDDEN DECELERATION TO 40MPH ON A FREELY MOVING FREEWAY WITH OTHER TRAFFIC TRAVELING AT 75MPH COULD BE A VERY DANGEROUS REAR-END COLLISION RISK.

VEHICLE STALLED WHILE DRIVING APPROXIMATELY 25-30MPH ON SURFACE STREET WITH 1/4 TANK OF GAS REMAINING.

I OWN A TOYOTA PRIUS PURCHASED IN FEB. 2004. ON THREE OCCASIONS, THE WARNINGS LIGHTS HAVE COME ON WHILE DRIVING AND THE CAR RAPIDLY LOOSES ALL POWER AND CANNOT BE MOVED. THE MOST RECENT INCIDENT OCCURRED TODAY, 8/14/05. I HAVE NOT BEEN SATISFIED THAT WHATEVER HAS CAUSED THIS PROBLEM HAS BEEN CORRECTED, AS APPARENT WITH TODAY'S INCIDENT. I HAVE REPORTED THESE INCIDENTS TO TOYOTA AND WILL SEND THEIR SUBSEQUENT CORRESPONDENCE. I HAVE OWNED TOYOTA VEHICLES SINCE 1980 AND THIS IS UNACCEPTABLE. WITH THIS THIRD INCIDENT, I INTEND TO PURSUE ALL AVENUES AVAILABLE TO RECTIFY THIS SITUATION. *NM

STARTING AROUND MAY,2005, WHEN VEHICLE WAS STARTED WITH THE BATTERY INDICATOR NOT QUITE AT FULL CAPACITY, LETS SAY SEVEN 'BARS', JUST PUTTING THE CAR IN REVERSE WOULD BEGIN THE GRADUAL DECLINE OF CHARGE. IF DRIVING UP A FRWY RAMP, THE INDICATOR WOULD SHOW THE CHARGE HAD DROPPED INTO THE 'RED' ZONE. AT THIS TIME THE ENGINE WOULD SOUND LIKE THE RPMS WERE ABOUT 4,000, A REAL REVVING SOUND. SLOWLY ,WITH A STEADY LEVEL DRIVE THE BATTERY WOULD RECHARGE AND LOOK AS IF IT WERE NORMAL. THERE WAS NO STALLING OF ENGINE BUT I RARELY DRIVE AS SLOW AS 65 MPH! THE WHOLE PROCESS, HAPPENING AT LEAST ONCE A DAY WAS VERY NERVE WRACKING...ESPECIALLY IN THE MOHAVE DESERT WITH MANY 18-WHEELERS SURROUNDING THE CAR. THE FIRST TIME IT HAPPENED I IMMEDIATELY CALLED TOYOTA OF TEMECULA VALLEY. I WAS TOLD THAT THIS WAS NOT GOOD AND TO BRING THE CAR IN FOR DIAGNOSIS. WHEN I BROUGHT IT IN, A 'TECHNICIAN' LOOKED AT THE INDICATOR AND SAID IT WAS OK AND NOT WORRY ABOUT IT. I HAD A DIFFICULT TIME BELIEVING THAT AND MADE AN APPT. WITH TOYOTA OF EL CAJON. WHEN THEIR TECHNICIAN USED A DIAGNOSTIC SCANTOOL HE ALSO SAID HE COULD NOT FIND A PROBLEM. I DID NOT BELIEVE HIM OR THE SERVICE $80/HR. GUY AND SAID THERE WAS EITHER SOMETHING WRONG WITH THEIR DIAGNOSTIC TOOLS AND/OR SOMETHING WRONG WITH THEM TO THINK I WOULD GO ALONG WITH THEIR STORY. I HAD NO IDEA HOW RIGHT I WAS UNTIL I READ ABOUT THE DEFECT INVESTIGATION ON YOUR WEBSITE. MY PRIUS HAS NOT STALLED (YET) BUT IT HAS ALL THE PROBLEMS LEADING UP TO IT. THE DEALER

DT: VEHICLE STALLED INTERMITTENTLY AND LOST POWER. *AK THE CONSUMER SOLD THE VEHICLE BACK TO THE DEALERSHIP. *JB

3 MONTHS AGO, ALL OF THE CHECK ENGINE LIGHTS IN MY TOYOTA PRIUS 04 CAME ON. I BROUGHT IT STRAIGHT TO THE DEALER. THEY TOOK IT FOR A TEST DRIVE, BUT THE LIGHTS HAD GONE OFF AND THEY REFUSED TO CHECK IT, SAYING IT WAS OKAY. THEN, YESTERDAY, ALL OF THE LIGHTS CAME ON AGAIN. I WAS ON THE SAN FRANCISCO BAY BRIDGE AND COULD NOT PULL OVER ANYWHERE. THEN, THE ACCELERATOR STOPPED WORKING AND THE CAR ROLLED TO A STOP. I CALLED 911 AND TRIED TO TURN OFF THE CAR. THE CAR WOULD NOT TURN OFF. THE ACCELERATOR STILL WOULDN'T WORK AND I WAS STUCK IN THE MIDDLE OF HEAVY TRAFFIC ON THE BRIDGE. FINALLY, CALTRANS USED A TOW TRUCK TO PUSH ME OFF OF THE BRIDGE. I WAS THEN TOWED TO THE TOYOTA DEALER. THE TOYOTA DEALER CHECKED THE CAR AND DISCOVERED THAT I HAD A BUG IN THE SOFTWARE CONTROL UNIT. HE UPDATED THE SOFTWARE AND, SUPPOSEDLY, IT NOW WORKS. I ASKED HIM IF IT WAS THE SAME ISSUE THAT WAS REPORTED IN THE NEWS AS A POTENTIAL RECALL AND HE SAID YES. *JB

2004 TOYOTA PRIUS INTERNAL COMBUSTION ENGINE FAILED TO START BUT VEHICLE OPERATED IN ELECTRIC MODE. WHEN BATTERY FAILED, THE VEHICLE SHUTDOWN IN PARK SO WE WERE UNABLE TO PUSH THE VEHICLE OUT OF THE STREET. FAILURE OF A COMPONENT SHOULD NOT MAKE IT IMPOSSIBLE TO MOVE THE VEHICLE. VEHICLE SHOULD NOT FAIL IN PARK. *JB

DT: THE CONTACT OWNS A 2004 TOYOTA PRIUS. THE CAR GOES INTO A MODE WHERE IT WILL NOT LET THE CONSUMER SHIFT INTO GEAR AND BECAUSE IT IS ELECTRIC SHIFT, THE CONSUMER DOES NOT KNOW THAT HE WAS UNABLE TO SHIFT INTO GEAR. IF HE IS ON A HILL THIS CONDITION WOULD MAKE THE VEHICLE COAST DOWN HILL. WHEN THE CONSUMER GETS INTO THE CAR, PRESSES THE BRAKE AND PRESSES THE POWER BUTTON THE CAR GOES INTO THE IGNITION ON MODE INSTEAD OF THE READY MODE. IF HE IS LOOKING AT THE DASH HE CAN TELL THIS HAS HAPPENED BUT IF HE DOES NOT LOOK AT THE DASH HE WOULD NOT KNOW THAT HE WAS UNABLE TO SHIFT THE CAR INTO GEAR. IF THE CAR IS ON A SLOPE IT WILL GO DOWN THE SLOPE AS SOON AS HE LETS OFF THE BRAKE AND STEPPING ON THE GAS DOES NOT MAKE A DIFFERENCE. OBVIOUSLY IF THERE IS ANYTHING IN FRONT OR BEHIND THE CAR AND THERE WAS SOMETHING IN THE CARS PATH DOWN THE HILL HE WOULD RUN INTO IT. ALSO, TWO VISITS TO THE DEALER UNABLE TO DUPLICATE OR FIX THE PROBLEM BECAUSE IT IS INTERMITTENT. *NM *JB

DT: WHILE DRIVING 50 MPH VEHICLE LOST POWER/DIED. CONSUMER TOOK VEHICLE TO DEALER WHO REPLACED THE ELECTRONIC THROTTLE BODY. *AK

DRIVING DOWNHILL ~50 MPH WHEN ALL WARNING LIGHTS CAME ON. CAR WOULDN'T ACCELERATE. GAS ENGINE WOULD NOT START AND BATTERY CHARGE WAS DROPPING FAST. LIMPED ~1 MILE HOME AT 25 MPH. TURNED OFF CAR, TOO LATE TO CALL TOYOTA THAT NIGHT. TURNED CAR ON AND GAS ENGINE STARTED RIGHT UP. ALL WARNING LIGHTS STILL ON, AND MAIN BATTERY NEARLY DRAINED. SLOWLY DROVE AROUND ON LOCAL STREETS, BATTERY CHARGED. PARKED AND TURNED OFF CAR. LATER IN DAY, TURNED ON CAR, ALL WARNING LIGHTS WERE OFF. TOOK IT TO DEALER WHEN WE GOT HOME. DEALER CLAIMED COMPUTER HAD NO RECORD OF THE PROBLEM. PRIOR TO THIS EVENT, TOYOTA HAD UPGRADED THE COMPUTER SOFTWARE ON THIS CAR AS DESCRIBED IN HV ECU SOFTWARE UPDATE 00204. WE WERE TOLD THIS FIXED THE STALLING PROBLEM, BUT OBVIOUSLY DOES NOT. JB

DT: CONTACT STATED THE ENGINE STALLED/LOST POWER ON TWO DIFFERENT OCCASIONS. *AK

CAR SUDDENLY LOST POWER WHEN BEING DRIVEN 30 MPH ON CITY ROAD. COMPUTER SAID BATTERY POWER LOST; SEEMS LIKE GAS ENGINE WAS NOT RECHARGING BATTERY, BUT THERE WAS NO WARNING UNTIL POWER LOSS. I WAS STUCK IN THE MIDDLE OF A CITY STREET WITH 2 SMALL CHILDREN, AS THE CAR WOULD NOT MAKE IT TO SIDE OF ROAD. ANOTHER MOTORIST HELPED PUSH ME TO SIDE OF ROAD AND NO ONE WAS HURT. THE GAS TANK WAS FULL AT THE TIME OF THIS INCIDENT. ALTHOUGH VEHICLE COULD NOT MOVE, THE DASHBOARD AND COMPUTER STILL HAD POWER; IT WOULD NOT ALLOW ME TO SHUT IT DOWN, OR REMOVE THE KEY FOB. THE CAR WAS TOWED TO A DEALERSHIP, AND NOW MUST BE TOWED TO ANOTHER DEALIERSHIP THAT SERVICES THIS MODEL. NO REPAIR HAS YET BEEN ATTEMPTED BUT I WANTED TO REPORT INCIDENT BECAUSE MY INTERNET RESEARCH INDICATED YOU WERE INVESTIGATING THIS MODEL FOR A NUMBER OF SIMILAR PROBLEMS. THE CAR WAS PURCHASED IN NOVEMBER 2003 AND HAS 15,299 MILES ON IT. I HAD ONE INCIDENT 12 MONTHS AGO WHEN I COULD NOT START THE VEHICLE, BUT I WAS ABLE TO FINALLY AFTER 10 MINUTES OR SO. I HAVE HAD NO PREVIOUS BREAK DOWNS HOWEVER.

I WAS ACCELERATING INTO A YIELD SITUATION WHERE I HAD ROOM TO MERGE FROM AN OFFRAMP AND THE GAS MOTOR DIDN'T KICK IN. THE CHECK-ENGINE LIGHT FLASHED, THE CAR VIBRATED, AND IT MOVED ONLY AS IF THE ELECTRIC MOTOR WAS GOING FOR A FEW SECONDS AND THEN, AS I WAS FLOORING IT, THE CAR JARTED OUT INTO THE INTERSECTION WHERE NOW THERE WASN'T ROOM AND I BECAME INVOLVED IN AN ACCIDENT

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.

I WAS DRIVING MY 2004 TOYOTA PRIUS APPROXIMATELY 35-40 MILES PER HOUR ON A LOCAL STREET WHEN THE "CHECK ENGINE" LIGHT AND THE SAFETY TRIANGLE LIGHT BOTH ILLUMINATED. I NOTICED THAT THE GAS ENGINE STOPPED RUNNING AT THE TIME OF THE FAILURE ALTHOUGH THE ELECTRIC MOTOR GOT ME TO THE DEALERSHIP WHERE THE CAR IS SERVICED. THE DELERSHIP CALLED ME IN A COUPLE OF HOURS TO TELL ME THAT THE CAR IS READY. I WAS TOLD THAT THEY JUST HAD TO RESET THE COMPUTER SOFTWARE TO FIX THE CAR. I KNOW THAT YOU ARE RESEARCHING THIS PROBLEM AND WANTED TO MAKE YOU AWARE OF MY SITIUATION. THANK YOU.

DT: WHILE DRIVING AT A STEADY PACE, THE VEHICLE STALLED. *AK *JB

DT: WHILE DRIVING ON DRY PAVEMENT AT 35 MPH THE VEHICLE STALLED. THE CONSUMER PULLED OFF TO THE MEDIAN. THERE WERE LIGHTS FLASHING IN DASHBOARD, THE DRIVER NOTICED THAT THE WARNING CODES INCLUDED DO NOT DRIVE, AND NO BRAKES, ETC. JUST BEFORE STALLING, THE WARNING CODES CAME ON, INCLUDING NO BRAKES, DO NOT DRIVE, ALL HAZARDS, THE EXPLANATION POINTED TO A TRIANGLE AND ALL PRECAUTIONARY SAFETY WARNING LIGHTS APPEARED. ONCE THE VEHICLE WAS STOPPED AT A MEDIAN THERE WAS NO RESPONSE FROM THE CAR, IT WAS TOTALLY DEAD. AFTER THE LIGHTS CAME ON, NO ACCELERATION, THERE WAS NO ENGINE SOUND TO THE OWNER'S KNOWLEDGE. THERE WAS NO OBVIOUS LOSS OF POWER STEERING AS FAR AS THE OWNER KNEW, IT WAS NOT EXTREMELY DIFFICULT TO GET TO THE MEDIAN. THE VEHICLE WAS NOT ABLE TO BE RESTARTED. THE OWNER TRIED TO START THE VEHICLE TWICE. AT THIS POINT, THE OWNER DIDN'T KNOW IF THE LIGHTS STAYED ON, BUT THE HAZARDS LIGHTS WERE WORKING AS SHE LEFT TO GO CALL FOR HELP. AT THE DEALERSHIP, THE VEHICLE WAS JUMPED TO GET IT OFF THE TOW TRUCK. THIS OCCURRED ABOUT 45 MINUTES. THE DEALER STATED THEY HAD NO IDEA WHAT COULD BE WRONG WITH THE VEHICLE, AND THIS SEEMED TO BE A NEW OCCURRENCE TO THE DEALERSHIP. *AK *SC *JB

DT: THE CHECK ENGINE LIGHT ILLUMINATED ON THE DASH AND REMAINED ON FOR ABOUT A DAY. OTHER LIGHT ILLUMINATED AS WELL BUT THE CONSUMER CAN'T REMEMBER WHICH ONES. THE CONSUMER MADE IT TO HIS DESTINATION WHERE HE STAYED 2 HOURS, AND UPON LEAVING THE ENGINE STARTED IMMEDIATELY. THE CONSUMER CALLED THE DEALER BUT THEY OFFERED NO DIAGNOSIS. THE DEALER DID NOT REPROGRAM THE ELECTRONIC CONTROL UNIT. *AK *NM

I WAS DRIVING ABOUT 45 MPH AND FELT THE POWER DIE AND SAW THE DASHBOARD WARNING LIGHTS COME ON. I HAD TO STOP AT A LIGHT AND THE CAR ACCELERATED BUT FELT LIKE IT WAS COASTING. I WAS VERY CLOSE TO HOME AND MADE IT ABOUT 500 FEET FROM MY DRIVEWAY WHEN THE CAR STOPPED. I COULD NOT TURN OFF THE ENGINE, THE LIGHTS NOR WOULD THE CAR GO INTO DRIVE OR REVERSE. SINCE I WAS IN THE MIDDLE OF THE ROAD, AFTER ABOUT 15 MINUTES I PUT THE CAR INTO NEUTRAL AND ROLLED DOWN THE HILL CLOSER TO THE CURB. AFTER I GOT TO THE SIDE OF THE ROAD, I ONCE AGAIN TRIED TO START THE CAR AND THIS TIME IT STARTED EASILY. IT WAS TOWED TO THE DEALER WHO HAD NEVER HEARD OF THIS PROBLEM NOR DEALT WITH IT. THEY CALLED THE NEXT DAY TO SAY THE COMPUTER SAID IT NEEDED TO BE REPROGRAMED AND THAT THE CAR WAS FIXED. THEY HAD NO IDEA WHY THIS HAPPENED BUT NOW THAT THE PROGRAM WAS RESET, "IT SHOULD NOT HAPPEN AGAIN." I LOVE THIS CAR HOWEVER, I AM GETTING 40-42MPG WHERE OTHERS I HAVE SPOKEN WITH ARE INTO THE 50 MPG RANGE, AND NOW I AM CONCERNED ABOUT IT STALLING OUT. THE CAR HAS ABOUT 13,000 MILES.

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 OPEN WITH TOYOTA #2005 00071145 BUT WITHOUT ANY HELP TO IDENTIFY THE PROBLEM.

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

(1) ENGINE STALLED WHEN ACCELERATING FROM STOPLIGHT. WEATHER WAS COOL (LOW-50S) AND RAINY. DASHBOARD WARNING LIGHTS LIT UP ('RED TRIANGLE OF DEATH', CHECK ENGINE, BRAKING SYSTEM) (2) DRIVER PULLED TO SIDE OF ROAD USING ELECTRIC POWER ONLY (3) DRIVER CALLED HUSBAND, WHO ADVISED WIFE TO CYCLE THE POWER OFF AND ON, POSSIBLY MULTIPLE TIMES, UNTIL THE ENGINE RESTARTED. CYCLING POWER SUCCESSFULLY RESTARTED ENGINE, BUT 'RED TRIANGLE OF DEATH' AND CHECK ENGINE WARNING LIGHTS REMAINED LIT. CAR OPERATED NORMALLY THEREAFTER. DEALER APPLIED TSB EG047-04 AT NO CHARGE. PROBLEM HAS NOT RETURNED. SUSPECT THIS IS ANOTHER INSTANCE OF 'PRIUS STALLING' PROBLEM. GIVEN THE NUMBER OF INCIDENTS (1), THE DEALER RESPONSE (SATISFACTORY) AND THE RECOVERABILITY FROM THE PROBLEM (POWER CYCLE), I CONSIDER THIS A MINOR PROBLEM. OTHERWISE HIGHLY SATISFIED WITH CAR.

CONSUMER STATED WHILE TRAVELING 40 MPH ALL OF A SUDDEN , THE LIGHTS ILLUMINATED ON THE DASHBOARD AND THEN EVERYTHING SHUT OFF.
