2004 TOYOTA PRIUS Engine And Engine Cooling Problems

I WAS DRIVING ON THE FREEWAY AT ABOUT 63 MILES PER HOUR, I HAD BEEN DRIVING FOR ABOUT 20 MINUTES WHEN MY ENGINE CUT OUT, ALL THE LIGHTS ON MY DASH TURNED ON INCLUDING THE CHECK ENGINE AND RED TRIANGLE WARNING LIGHT. I DRIFTED TO THE SHOULDER AND POWERED THE CAR OFF. I TRIED TO START IT 2 MORE TIMES, BOTH TIMES THE ENGINE DID NOT START AND THE RED TRIANGLE AND THE CHECK ENGINE LIGHTS CAME ON AGAIN. I WAITED LONGER AND TRIED TO POWER UP THE ENGINE AGAIN, IT STARTED WITH THE CHECK ENGINE LIGHT ON. I TOOK IT TO THE DEALERSHIP 3 DAYS LATER (THEY COULD NOT SEE ME SOONER), RAN THE CODES AND IT ONLY CAME UP WITH THE CODE POAOF, WHICH MEANS THAT THE ENGINE DID NOT START. THEY HAD NO EXPLANATION OF WHAT HAPPENED AND DID NOT SEEM TO SHARE MY CONCERN THAT THIS...

TL*THE CONTACT OWNS A 2004 TOYOTA PRIUS HYBRID. WHILE DRIVING APPROXIMATELY 60 MPH, THE CHECK ENGINE WARNING LIGHT, AND AN UNKNOWN WARNING LIGHT ILLUMINATED ON THE INSTRUMENT PANEL. THE DEALER WAS NOTIFIED AND ADVISED THE VEHICLE WAS SAFE TO DRIVE; UNLESS THE TEMPERATURE, BRAKE OR OIL WARNING LIGHTS ILLUMINATED. THE VEHICLE BEGAN TO LOSE POWER AND THE ANTI-LOCK BRAKE SYSTEM WARNING LIGHT ILLUMINATED. THE VEHICLE WAS MANEUVERED TO THE SIDE OF THE HIGHWAY. THE VEHICLE WAS TOWED TO THE DEALER. THE FAILURES WERE RELATED TO THE INVERTER WATER PUMP AND THE SKID CONTROL ELECTRONIC CONTROL UNIT (ECU). THE INVERTER WATER PUMP WAS REPLACED. THE FAILURE OCCURRED A SECOND TIME. THE VEHICLE WAS REPAIRED FOR THE MALFUNCTION. THE FAILURE AND CURRENT MILEAGES WERE 61,000.

WE OWN A 2004 TOYOTA PRIUS. ON 02/18/2010 IT LOST POWER ON THE ROAD, MAJOR MALFUNCTION LIGHTS CAME ON, AMONG OTHERS, AND HAD TO BE TOWED TO THE TOYOTA DEALER IN CARLSBAD, CA. AFTER DIAGNOSING THE PROBLEM, THEY SAID THE COMPUTER HAD FAILED AND NEEDED TO BE REPLACED. WHEN THE COMPUTER WAS REPLACED IT STARTED TRANSMITTING NEW PROBLEM CODES, NAMELY, POA94, POA78, PO279, AND PO555, WHICH MEANT THAT THE TRANSAXLE HAD FAILED, AND COMPUTER CODES SHOW THAT THE INVERTER COULD FAIL ALSO. TOTAL REPAIR COST: $5,594.00 SO FAR. IF THE INVERTER FAILS, IT WOULD BE A TOTAL OF $9,843.00 TO REPAIR. I DON'T SEE WHO WOULD PAY THIS EXORBITANT AMOUNT, LET ALONE BEING ABLE TO AFFORD IT. THE SAME INCIDENT OCCURRED ON 09/15/2008. THE PRIUS HAD LOST POWER AND WE TOOK IT IN TO THE DEALER. THEY PERFORMED A DIAGNOSTICS TEST, TEST DROVE THE VEHICLE ON THE FREEWAY FOR 9...

2004 PRIUS: AFTER DRIVING AT 10MPH ON GRAVEL ROAD WITH POTHOLES AND THEN TURNING ON TO SMOOTH PAVED ROAD ENGINE SPEED AND SPEEDOMETER STARTED TO VARY WILDLY WITH SPEEDOMETER GOING UP TO 45MPH DOWN AND BACK UP AGAIN FOR A 5 MINUTE PERIOD WHILE DRIVING ON THE PAVED ROAD AT ABOUT 30MPH. THIS CONTINUED BUT CAR ITSELF DID NOT ACCELERATE ABNORMALLY DESPITE CHANGE IN ENGINE SPEED AND WILD SPEEDOMETER. *TR

ON 23 JAN 2010, WHILE DRIVING I-85N IN THE SOUTH CAROLINA MOUNTAINS THE CAR STALLED AT 70MPH. AN AUDIBLE ALERT SOUNDED, THE CAR JERKED AND THREE WARNING LIGHTS WENT OFF. I COASTED THE CAR TO THE SHOULDER AND SHUT THE CAR DOWN. I RESTARTED THE CAR -- THE WARNING LIGHTS CLEARED -- AND CONTINUED DRIVING. ABOUT 30 MINUTES LATER, STILL IN THE MOUNTAINS, THE SAME THINGS OCCURRED (STALL WHILE DRIVING 70MPH ON THE INTERSTATE.) WHEN I RESTARTED THE CAR A YELLOW "!" WARNING REMAINED ON. I CONTINUED THE TRIP TO VIRGINIA WITH NO FURTHER PROBLEMS. THE WARNING LIGHT WENT OUT. ON 5 FEB 2010, WHILE DRIVING ON I-95S IN THE SOUTH CAROLINA MOUNTAINS THE CAR STALLED, WARNING LIGHTS AND AUDIBLE ALARM SOUNDED. UPON RESTART THE "!" STAYED ON. THIS HAPPENED TWO MORE TIMES; ONCE ON I-95 AND ONCE ON I-20. THE LAST TWO TIMES THE RED TRIANGLE WARNING LIGHT STAYED...

ABOUT 40% OF THE TIME, MY TOYOTA PRIUS DOESN'T WANT TO STOP OR SLOW DOWN WHEN THE BRAKES ARE APPLIED. UNDER THESE CONDITIONS, I HAVE TO APPLY THE BRAKES HARD AND THEN THE CAR WILL SLOW DOWN. IT FEELS LIKE THE CAR WANTS TO "RUN AWAY" WHEN THE BRAKES ARE APPLIED. IT EXHIBITS THIS BEHAVIOR IN MANY CIRCUMSTANCES: STOPPING AT A STOP LIGHT, SLOWING DOWN ON AN EXPRESSWAY, OR SLOWING DOWN ON A CITY STREET. *TR UPDATED 11/23/09 *BF THE CHECK ENGINE LIGHT ILLUMINATED. THE PASSENGER FRONT WINDOW SWITCH WASN'T OPENING OR CLOSING THE WINDOW UNLESS THE MASTER SWITCH WAS USED. THE THROTTLE BODY HAD TO BE CLEANED. THE FAN BELT AND BRAKE LIGHT SWITCH WERE REPLACED. UPDATED 11/24/09 UPDATED 01/06/10 *BF UPDATED 01/07/10.*JB

2004 TOYOTA PRIUS. DRIVING AT 70 MPH ON I-57 NORTH. WHILE DRIVING THE GASOLINE ENGINE STOPPED FUNCTIONING, TRIGGERING SEVERAL WARNING LIGHTS. I PULLED THE CAR OFF TO THE SIDE OF THE HIGHWAY AND MANAGED TO EXIT THE HIGHWAY ON BATTERY POWER. THERE WAS A RECALL IN 2005 FOR A SIMILAR CONDITION. MY PRIUS HAD THE RECALL WORK PERFORMED IN OCTOBER 2005 FOR THE SOFTWARE PROBLEM. THE TOYOTA DEALER IS UNABLE TO FIND ANY REASON FOR THE PROBLEM AND CAN NOT REPLICATE THE ENGINE FAILURE. AS A RESULT, THEY WILL NOT PERFORM ANY FURTHER INVESTIGATION OR MAINTENANCE ON THE VEHICLE FOR THIS PROBLEM. I HAVE A CASE PENDING WITH TOYOTA CUSTOMER CARE, BUT DO NOT EXPECT ANY FURTHER ASSISTANCE FROM THEM. I AM ALSO BEING CHARGED LABOR FOR THE DEALER TO INSPECT THE VEHICLE. THERE WAS NO FIRE OR PROPERTY DAMAGE, BUT IF I HAD NOT BEEN IN THE RIGHT HAND...

2004 PRIUS STALLED WHILE DRIVING. TOWED TO DEALER WHO FOUND NO PROBLEM. *TR

2004 TOYOTA PRIUS STALLING. AFTER SPEAKING W/ THE TOYOTA CONSUMER HELPLINE, I'VE LEARNED THAT THE COULD PUT A PROGRAM IN THE COMPUTER THAT GIVES YOU ENOUGH TIME TO PULL TO THE SIDE OF THE ROAD BEFORE YOU STALL. I RESPONDED THAT THERE ISN'T ALWAYS A SHOULDER TO PULLOVER TO. I STARTED GETTING WARNING LIGHTS AT 6,500 MI. I NOW HAVE 36,880 MI. IN THE BEGINNING, THE LIGHTS WERE JUST A JOKE OR A NUISANCE WHEN I HAD TO BRING IT IN TO THE DEALER. ON NOV 11, I STALLED ALONG W/ WARNING LIGHTS. YOU CAN PULL OVER AND SHUT IT OFF,WAIT A MINUTE, RESTART AND DRIVE HOME WITH WARNING LIGHTS, BUT THEY GO OUT WHEN YOU START UP TO GO TO DEALER. I BROUGHT IT TO THEM ANYWAY, BUT AFTER THEY LOOKED AT THE CODES I WAS TOLD IT WAS SOFT CODES AND THAT THERE WAS NOTHING THAT THEY COULD...

DT*: THE CONTACT STATED WHILE DRIVING 30 MPH THE VEHICLE INTERMITTENTLY STALLED WITHOUT WARNING. THIS OCCURRED ON THREE OCCASIONS. THE VEHICLE WAS MANEUVERED OFF THE ROAD AND TOWED TO THE DEALER EACH TIME WHERE THE PROBLEM COULD NOT BE DUPLICATED.

MY TOYOTA PRIUS 2004 VIN [XXX] ENGINE SUDDENLY STALLED ON THE FREEWAY. I STILL CAN'T RESTART THE ENGINE. AS OF 10/17/05 DEALER STILL CAN'T FIND THE REASON. *JB UPDATED 07/18/2012 *JS INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I WAS DRIVING ON THE HIGHWAY AT BETWEEN 40-55 WHEN THE ENGINE STALLED. I TRIED TO RESTART IT, BUT IT WOULD NOT START. THE CAR HAD TO BE TOWED. THERE IS A ONE-WEEK WAIT ON ITS REPAIR. THIS HAPPENED APPROX. 240 MILES FROM HOME. THIS IS THE SECOND TIME THIS HAS HAPPENED. PRIUS 2004. *NM

DT: 2004 TOYOTA PRIUS. WHILE DRIVING 55-60 MPH VEHICLE CONSTANTLY LOST POWER. THE ENGINE CHECK LIGHT CAME ON. THE CONSUMER HAD DIFFICULTY RESTARTING THE VEHICLE. *AK *JB

WAS DRIVING HOME AT APPROXIMATELY 50MPH WHEN THE 2004 PRIUS SUDDENLY SHUT DOWN AND WAS INOPERATIVE. WE PULLED THE CAR OVER, WAITED ABOUT 15 MINUTES, AND WAS ABLE TO RESTART. THE MOTOR.

MY 2004 PRIUS "DIED" WITH LITTLE WARNING WHILE I WAS DRIVING ABOUT 40 MPH ON A BUSY STREET. I COASTED TO A STOP WITH CARS FLYING BY ME. VERY DANGEROUS. CAR WAS TOWED TO THE DEALER, WHO EXPLAINED THERE WAS A SOFTWARE PROBLEM AND THEY REPROGRAMMED THE CAR'S COMPUTER. THIS IS AN EXTREMELY DANGEROUS PROBLEM! I'M AFRAID TO DRIVE THIS CAR.

APPROACHING ENTRANCE RAMP TO I495 N EXIT 32 WESTFORD MA AT MODEST SIDE STREET SPEED 25-40 APPROXIMATELY. CAR RAPIDLY LOST ACCELERATION. CONTINUED FOR ABOUT ONE MINUTE ONTO THE INTERSTATE AND STALLED ON THE SHOULDER. BATTERY INDICATED SHOWED ONLY ONE BAR. GAS AT LEAST 1/3 FULL. ELECTRIC WINDOWS AND DISPLAYS AND LIGHTS WORKED. CERTAIN WARNING INDICATORS WERE LIT INCLUDING RED DANGER TRIANGLE. COULD NOT TURN OFF THE POWER OR REMOVE THE KEY. AFTER 20-25 MINUTES, WHILE WAITING FOR THE TOW TRUNK, I WAS ABLE TO POWER OFF AND ON AND THEN THE CAR STARTED AND I DROVE HOME (30 MILES). PERFORMANCE APPEARED NORMAL BUT THE RED TRIANGLE AND A FEW OTHER INDICATORS REMAINED LIT.

TOYOTA PRIUS GAS ENGINE STALLED AFTER TOYOTA SERVICE PATCH WAS DOWNLOADED TO CORRECT PROBLEM. BOUGHT CAR MARCH 1, 2004. CAR STALLED MAY 13 AND JUNE 1- SEE REPORT FILED UNDER MAY 13 DATE. JULY 31, 2004 TOYOTA DOWNLOADED PATCH TO FIX THE PROBLEM AND WE THOUGHT IT WAS FINE. CAR WAS OK FOR ALMOST A YEAR. THEN, JUST 2 WEEKS AGO ON JUNE 2, 2005 I WAS DRIVING ON THE HIGHWAY (LUCKILY IN A LOT OF SLOW TRAFFIC SO ONLY GOING ABOUT 40 MPH) AND THE GAS ENGINE DIED AGAIN SO THE CAR DROPPED TO 20MPH ON THE ELECTRIC ENGINE. ALL WARNING LIGHTS CAME ON AGAIN. THIS TIME I STOPPED AND RESTARTED THE CAR AND THE ENGINE (GAS AND ELECTRIC) CAME BACK ON. THIS IS WHAT THE DEALER HAD SAID THAT THE OTHER CUSTOMERS HAVING THE PROBLEM HAD FOUND- IF YOU STOP AND TURN IT BACK ON AFTER A STALL...

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

MY 2004 PRIUS LOST POWER WHEN I WAS TRAVELING AT ABOUT 65-70 MILES PER HOUR ON 2/21/05. I HAD ELECTRIC POWER FOR A FEW MINUTES SO THAT I COULD PULL OFF AT AN EXIT. ALL THE WARNING/CAUTION LIGHTS CAME ON. THE KERN TOYOTA DEALERSHIP IN WINCHESTER VA HAD MY CAR TOWED IN. THEY KEPT THE CAR OVERNIGHT. THEY SAID THAT THEY REPROGRAMMED MY COMPUTER AND THE CAR WAS FINE. THEY OFFERED NO OTHER EXPLANATION OR POSSIBLE FUTURE CONCERNS. I REPORTED THIS TO TOYOTA MANAGEMENT THIS MORNING AND HAVE A CONFIRMATION # IF NEEDED. I JUST SAW THE ARTICLES WHERE THEY NOTED 33 OTHER INCIDENTS LIKE MINE.

I OWN A 2004 TOYOTA PRIUS, 15680 MILES. THE ENGINE STOPPED WHEN I WAS DRIVING AT ABOUT 60 MPH AND ALL WARNING LIGHTS CAME ON. I WAS ABLE TO DRIVE IT ON THE ELECTRICAL MOTOR FOR ABOUT 1 MILE TO A GAS STATION BEFORE THE BATTERY RAN OUT. I HAD IT TOWED TO MY DEALER, TOYOTA OF BOWIE IN MD. THE NEXT DAY, IT STARTED RIGHT UP AND THEY SAID THAT THEY CHECKED IT AND COULD FIND NOTHING WRONG WITH IT. THIS HAPPENED A FEW DAYS BEFORE NEWS STORIES OF SIMILAR COMPLAINTS. THIS IS A FRIGHTENING, AND POTENTIALLY VERY DANGEROUS PROBLEM. I'M SURPRISED AND UPSET THAT THE DEALER OR TOYOTA HAS NOT CONTACTED ME WITH A FIX SINCE THEY HAVE LEARNED ABOUT THIS PROBLEM.

I HAVE A 2004 PRIUS THAT STALLED ON THE FREEWAY THIS FEBRUARY FOR NO REASON. WHEN WE TOOK IT TO THE DEALER, THE MECHANICS SAID THEY HAD NO IDEA WHY IT HAPPENED, BUT THAT THEY "RESET THE COMPUTER" AND IT WOULDN'T HAPPEN AGAIN.

I PULLED OUT OF A PARKING SPACE INTO TRAFFIC AND THE CAR IMMEDIATELY STALLED. I COULDN'T TURN IT OFF, AND I COULDN'T GET IT INTO DRIVE. PARK AND NEUTRAL WERE THE ONLY OPTIONS. TRAFFIC WAS COMING AT ME FROM BOTH DIRECTIONS AND THERE WAS NOTHING I COULD DO, BUT PUT ON THE 4 WAY FLASHERS.USING MY CELL PHONE I CALLED THE LOCAL DEALERSHIP AND THEY ADVISED ME TO HAVE THE CAR TOWED. I CALLED THE TOW COMPANY.

YAPS (YET ANOTHER PRIUS STALL). I WAS NOT GOING FAST - PROBABLY ABOUT 10-15 MPH. JUST LIKE THE OTHER REPORTS, IT LOST POWER, ALL THE WARNING LIGHTS CAME ON, AND IT COASTED TO A HALT. I WAS ABLE TO RESTART IT BUT THE ICE WOULD NOT KICK IN SO IT RAN IN ELECTRIC MODE ONLY. AFTER LESS THAN A MILE THE BATTERY WAS ALMOST DRAINED SO I HAD TO PULL OVER AND PARK IT. HAD IT TOWED IN TO THE NEAREST DEALER - TOYOTA OF SEATTLE - WHERE THEY SAID IT WAS A SOFTWARE ISSUE AND THEY'D SEEN IT BEFORE. THEY PERFORMED AN UPGRADE AND RETURNED IT TO ME.

DAD: VEHICLE RUNS AND SUDDENLY STALLS AND STOPS WORKING. OWNER ATTEMPTS TO START CAR AGAIN, AND IT DOES NOT START. CAR WAS TAKEN TO THE DEALER THREE TIMES, AND DEALER FIXED IT. BUT, AFTER SOME TIME THE CAR DID NOT WORK AGAIN. OWNER STATED THAT CAR WAS SERVICED ON REGULAR BASIS.*AK

I AM ESTIMATING THE DATES - I TOOK MY 2004 PRIUS TO THE DEALER ON OCTOBER 12, AS IT WAS NOT DRIVING RIGHT SINCE I HAD DONE A "HARD BRAKE" THE WEEK BEFORE. THE SERVICE DEPT WAS UNABLE TO FIND ANYTHING AMISS. THEN, WHILE DRIVING TO WORK THAT FRIDAY, MY CAR INDICATED THAT I NEEDED TO STOP THE CAR IMMEDIATELY (VIA THE RED TRIANGLE ETC. LIGHTS ON DASHBOARD). I WAS TRAVELLING AT ABOUT 45 MILES PER HOUR AT THE TIME. I COASTED INTO A LEFT TURN LANE, BUT WAS UNABLE TO COMPLETE THE TURN INTO THE PARKING LOT AS THE CAR HAD SHUT DOWN. I WAS PUSHED INTO THE PARKING LOT. I CONTACTED THE DEALER AND THE CAR WAS TOWED TO THE NEAREST DEALER (LARRY MILLER TOYOTA ON W. BELL ROAD). I WAS TOLD THE ECU WAS REPROGRAMMED AND THAT THERE WAS A SERVICE BULLETIN THAT WAS NOT SENT TO...

MY 2004 PRIUS CUT OUT AT ABOUT 25 MPH AND WOULD NOT RESTART.

ENGINE WARNING LIGHT CAME ON WHILE DRIVING APPROXIMATELY 55-60 MPH. GAS POWER QUIT AND CONSUMED ALL ELECTRIC POWER AND CAR STOPPED. COASTED TO THE SIDE OF THE ROAD. COULD NOT GET THE CAR TO GO INTO ANY GEAR -- STUCK IN PARK. HAD TO HAVE IT TOWED TO DEALER.

MY 2004 PRIUS' COMBUSTION ENGINE SHUT DOWN ON THE FREEWAY IN SEP'04. THE CAR SWITCHED TO BATTERY MODE ONLY AND ROLLED ON UNTIL THE BATTERY WAS COMPLETELY DRAINED AND THEN COMPLETELY STALLED. I GOT STUCK IN LANES, CREATED A RUSH-HOUR TRAFFIC JAM, AND HAD TO BE PUSHED TO A SHOULDER BY A POLICE CAR. THE CAR WAS TOWED TO A DEALER WHO SAID IT WAS A SOFTWARE GLITCH WHICH THEY PROCEEDED TO FIX AND THE CAR HAS BEEN WORKING WELL SINCE THEN.

MY 2004 TOYOTA PRIUS STALLED WHILE TRAVELING ABOUT 40-45 MPH WITH A FULL TANK OF GAS ON 5/14/05. THE CHECK ENGINE LIGHT CAME ON AND IT COASTED TO A STOP. I TURNED OFF THE POWER SWITCH AND RESTARTED IT AND THE ENGINE CAME BACK ON AND RAN FINE EXCEPT WITH THE CHECK ENGINE LIGHT STILL ON. THE NEXT DAY THE CHECK ENGINE LIGHT WAS OFF AND THE ENGINE RAN FINE. I TOOK IT IN TO THE DEALER'S SERVICE CENTER AND THEY SAID THEY DID SOMETHING WITH THE SOFTWEAR AND IT SHOULD RUN FINE NOW.

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 FOUR SEPARATE OCCASIONS THE PRIUS HAS HAD A COMPLETE LOSS OF POWER TO THE GASOLINE ENGINE, ALL THE WARNING INDICATOR LIGHTS HAVE BEEN ILLUMINATED AND THE CAR WAS ABLE TO TRAVEL ONLY ON BATTERY POWER FOR A VERY SHORT DISTANCE BEFORE DRAINING THE BATTERY. TWICE THIS HAS OCCURRED AFTER STOPPING AT A STOP SIGN AND ATTEMPTING TO PROCEED FORWARD. TWICE IT HAS HAPPENED WHILE DRIVING ON THE HIGHWAY AT 60-70 MPH. WHEN IT OCCURRED ON THE HIGHWAY THE CAR LOST POWER EXCEPT FROM THE BATTERY THAT ALLOWED ONLY 40-42 MPH MAXIMUM SPEED. TWICE THE CAR WAS TOWED TO THE DEALER. THE FIRST TIME THEY PERFORMED A SOFTWARE UPDATE THE SECOND TIME THEY RESET THE COMPUTER. THE LAST TWO TIMES IT HAS HAPPENED I HAVE BEEN ABLE TO STOP THE CAR, DISCONNECT THE 12 VOLT BATTERY WHICH HAS RESET THE SYSTEM AND THE CAR PERFORMS AS EXPECTED. THIS WOULD APPEAR...

2004 PRIUS, GAS ENGINE STALLED WHILE EXCELLERATING TO MERGE ONTO FREEWAY DURING RUSH HOUR, WAS FORCED TO EXIT ON ELECTRIC ENGINE IN HEAVY TRAFFIC DRIVING AT 30MPH. AFTER EXITING FREEWAY AND TURNING CAR OFF IT WOULD NOT RESTART. VEHICLE FINALLY RESTARTED AND I WAS ABLE TO DRIVE WITH MASTER CHECK ENGINE LIGHT ON. DEALER SAID THE CAR NEEDED TO HAVE SOFTWARE RESET, BUT NEVER GAVE EXPLAINATION OF WHAT CAUSED ORIGINAL PROBLEM. I AM GUESSING AT THE INCIDENT DATE IT WAS MONTH OR SO BACK.

WHILE DRIVING AT 30 - 35 MPH, THE ENGINE OF MY 2004 TOYOTA PRIUS CUT OFF WITHOUT WARNING. THE "WARNING LAMP" TURNED ON AT THE TIME THE ENGINE QUIT, NOT BEFORE. I COASTED TO A STOP IN A NEARBY PARKING LOT. WHEN I COULD NOT RESTART THE CAR, I CALLED AAA FOR TOWING. AFTER WAITING 30 MINUTES, I TRIED TO START THE ENGINE AGAIN, AND IT STARTED WITH NO PROBLEM. NO WARNING LIGHTS WERE ON, AND I HAD NO FURTHER PROBLEM. I HAD A SECOND INCIDENT IDENTICAL TO THE FIRST, EXCEPT THIS TMIE I TRIED TO RESTART THE MOTOR AFTER WAITING ONLY 4 -5 MINUTES.
