2004 TOYOTA PRIUS Power Train Problems

SHIFTER STICKING IN DRIVE POSITION AS OPPOSED TO RETURNING TO ITS HOME POSITION. WHEN THIS SHIFTER STICKS, THE PARK BUTTON BECOMES DISABLED AND VEHICLE REMAINS IN DRIVE EVEN THOUGH PARK BUTTON IS ENGAGED

VEHICLE SLIPS INTO NEUTRAL AND/OR WILL NOT REVERT BACK TO DRIVE OR REVERSE. THE PROBLEM IS MOST PREVALENT WHEN WEATHER GETS EXTREMELY HOT (99 DEGREES +). THE ONLY WAY I WAS ABLE TO GET MOVING WAS TO PHYSICALLY HOLD MY SHIFTER IN DRIVE POSITION; THE SECOND I LET IT GO, THE VEHICLE AUTOMATICALLY REVERTED BACK TO NEUTRAL. I HAD MY VEHICLE OVER TO A LOCAL TOYOTA DEALERSHIP ABOUT THIS ISSUE. THE TECHNICIAN AT THAT TIME DID ACKNOWLEDGE THIS WAS STRANGE AND WITNESSED THE PROBLEM ON SITE. AFTER DIAGNOSING THE VEHICLE, HE COULD NOT FIND ANYTHING WRONG; I WAS TOLD TO LEAVE THE CAR WITH THE DEALERSHIP FOR A FEW DAYS TO TRY TO REPLICATE THE PROBLEM; NO OTHER MEANS OF TRANSPORTATION WAS OFFERED. I FELT IT WOULD HAVE BEEN AN UNFAIR EXPENSE TO RENT A CAR FOR AN UNDETERMINED AMOUNT OF TIME WHILE TOYOTA DIAGNOSED MY VEHICLE FOR SEVERAL DAYS;...

THE BASIC PROBLEM: THE GEAR SHIFT SELECTOR STICKS IN DRIVE OR "B" (ENGINE BRAKING MODE). IF THE DRIVER STOPS THE VEHICLE, WITH THE BRAKE DEPRESSED, AND THEN PRESSES THE PARK BUTTON TO PUT THE VEHICLE IN PARK, THE VEHICLE REMAINS IN DRIVE MODE. THE VEHICLE WILL MOVE AS SOON AS THE DRIVER LIFTS THEIR FOOT FROM THE BRAKE PEDAL, EVEN THOUGH THE DRIVER BELIEVES THEY HAVE ENGAGED THE PARK MODE. THE DRIVER HAS TO PLACE THE NORMALLY SPRING-ACTIVATED GEARSHIFT LEVER INTO THE HOME POSITION BEFORE THE CAR WILL SHIFT INTO PARK. DANGER TO THE DRIVER AND OTHERS WHO DRIVE THE CAR. THIS IS VERY DANGEROUS, AS THE DRIVER GETS VERY USED TO BEING ABLE TO PLACE THE CAR INTO PARK BY PRESSING THE PARK BUTTON. OTHERS WHO DRIVE THE CAR, LIKE PARKING ATTENDANTS OR FRIENDS, WILL NOT SUSPECT A PROBLEM. THE FAILURE OF THE PARK MECHANISM WHEN THIS HAPPENS IS...

TL* THE CONTACT OWNS A 2004 TOYOTA PRIUS. THE CONTACT STATED THAT THE GEAR SHIFTER COULD NOT BE SHIFTED INTO PARK. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE SHIFTER ASSEMBLY NEEDED TO BE REPLACED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE VEHICLE WAS NOT REPAIRED. THE APPROXIMATE FAILURE MILEAGE WAS 120,000 AND THE CURRENT MILEAGE WAS 150,000. *TR

CAR SHIFTS TO NEUTRAL UPON SHIFTING TO DRIVE OR REVERSE WHEN STARTING CAR (O MPH) CAR SHIFTS BACK TO NEUTRAL WHEN DRIVING (25 MPH) PROB. SEEMS RELATED TO COLD AMBIENT TEMPERATURE. *TR

A COMBINATION OF 2 ISSUES. FOR SEVERAL MONTHS THE GEAR SHIFT SELECTOR HAS BEEN STICKING IN THE D POSITION INSTEAD OF AUTOMATICALLY RETURNING TO THE N POSITION AS IT SHOULD. IT IS DOCUMENTED BY OTHER PRIUS OWNERS THAT THE DUST COVER INSIDE THE SHIFTER CAN BEGIN TO WARP OVER TIME CAUSING THIS STICKING. HTTP://PRIUSCHAT.COM/THREADS/GEAR-SHIFTER-STICKS.38199/ I THOUGHT THIS WAS JUST A NUISANCE ISSUE UNTIL LAST MONTH AND ON ONE OTHER OCCASION WHERE THE SHIFTER STUCK IN THE D POSITION AND I HADN'T NOTICED AND WHEN I ATTEMPTED TO PUT THE CAR INTO "PARK" BY PRESSING THE SEPARATE P BUTTON THE CAR WOULD NOT GO INTO PARK. IT IS NOW APPARENT THAT THIS IS RELATED TO THE SHIFTER STICKING IN THE D POSITION AND PREVENTING THE CAR FROM GOING INTO PARK. THERE IS ONE REPORT OF A NEAR INCIDENT OF THE CAR DRIVING AWAY WHEN THE DRIVER DIDN'T NOTICE THAT THE CAR...

THE DASH GEAR SELECTOR (COMMON TO 2004 - 2009 G2 PRIUS) BEGAN CLICKING WHEN I CHANGED GEARS (R-D-N) I RESEARCHED THE SUBJECT AND LEARNED THAT THIS CAN LEAD TO THE SHIFTER LOCKING IN D OR R, A HAZARDOUS CONDITION. I ALSO LEARNED THAT SOME DIY OWNERS HAVE DISCOVERED A WARPED DUST PLATE IN THE SHIFTER COMPONENT. IT CAUSES THIS PROBLEM. THEIR SOLUTION IS TO REMOVE THE PLATE, TRIM IT, AND REASSEMBLE THE PART. LINK 1 BELOW IS A GOOGLE SEARCH THAT REVEALS THE OTHER TWO LINKS I INCLUDED. NOT ALL OF THE HITS ARE RELEVANT. THE THIRD LINK HAS A VIDEO WITH CLEAR IMAGES OF THE PROBLEM AND THE DIY 'SOLUTION.'

UNFORTUNATELY THE GEAR SHIFT MODULE INCLUDED WITH THE CAR DOES NOT HAVE A LIFETIME CONSISTENT...

TL* THE CONTACT OWNS A 2004 TOYOTA PRIUS. THE CONTACT STATED THAT THE GEAR SHIFTED FROM DRIVE INTO NEUTRAL SEVERAL TIMES INDEPENDENTLY. THE CONTACT HAD TO HOLD THE GEAR FOR IT TO REMAIN IN DRIVE. THE VEHICLE WAS TAKEN TO THE DEALER WHO PERFORMED A DIAGNOSTIC. THE FAILURE WAS LOCATED AT THE GEAR SHIFTER.

AUTOMATIC TRANSMISSION CONTROL PROBLEMS. THE TRANSMISSION CONTROL LEVER BECAME WORN. SOMETIMES THE VEHICLE BEGAN TO THE ROLL WITH THIS DEFECT. THE INTERNAL SPRING THAT MOVES THE TRANSMISSION LEVER BACK TO THE PREVIOUS POSITION BECAME WORN AND NOW IT DOESN'T RETURN TO IT'S NORMAL POSITION WHEN PUTTING IT IN REVERSE OR DRIVE. THE SHIFTER LEVER WAS STICKING IN DRIVE OR REVERSE. *TR

2004 TOYOTA PRIUS. CONSUMER ASSERTS THAT VEHICLE ACCIDENT WAS CAUSED BY A COMPUTER MALFUNCTION *TGW THE CONSUMER STATED PRIOR TO THE ACCIDENT, ON ONE OCCASION, THE VEHICLE BOLTED AND JERKED SLIGHTLY AS SHE STOPPED THE VEHICLE. WHEN SHE ATTEMPTED TO TAKE OFF, THE VEHICLE RESPONDED SLUGGISHLY AND THEN ACCELERATED QUICKLY. THE DAY OF THE ACCIDENT, AS THE CONSUMER APPROACHED THE STOP SIGN, THE VEHICLE STARTED BUCKING AND JERKING VIOLENTLY. AFTER SHE PULLED OFF FROM THE STOP SIGN, SHE CRASHED INTO A LARGE SUV. THE CONSUMER STATED SHE SAW THE SUV PASS, SO SHE PURPOSELY WAITED SO SHE COULD MAKE A LEFT TURN, BUT ENDED CAUSING SEVERE DAMAGE TO HER VEHICLE. *JB

I WAS ENTERING A MAJOR HIGHWAY FROM A PARKING LOT WHEN THE ENGINE SUDDENLY ACCELERATED AT FULL SPEED. VISIBILITY WAS GOOD. THERE WAS A SMALL POTHOLE SO I DID TOUCH THE ACCELERATOR. NEXT I WAS IN THE MIDDLE OF THE HIGHWAY & HIT BY A CAR GOING 65MPH. I DO NOT THINK I HIT THE ACCELERATOR RATHER THAN THE BRAKE ALTHOUGH THAT WAS THE ONLY EXPLANATION AT THE TIME. *TR

2004 TOYOTA PRIUS-WHILE DRIVING VARIOUS WARNING LIGHTS CAME ON INCLUDING GO TO A DEALER IMMEDIATELY WHICH I DID. PROPULSION POWER ALMOST VANISHED IN ONE MILE OF DRIVING. DEALER FIXED THE PROBLEM AT NO CHARGE SAYING THEY "REPROGRAM ENGINE ECU"

I HAVE HAD 3 'STALLS' OF MY 2004 PRIUS WHICH I DRIVE 150 MILES A DAY AND IT HAS 48K MILES ON IT. ALL OF THE ENGINE STALLS HAVE BEEN AT LOW SPEED (UNDER 20 MPH) AND HAVE BEEN PRECEEDED BY A RED WARNING TRIANGLE LIGHT AND THE SCREEN DISPLAYING SOMETHING LIKE 'CRITICAL PROBLEM'. ON ONE INCIDENT I WAS IN HEAVY TRAFFIC AND MANAGED TO USE THE ELECTRIC MOTOR TO GET ME TO THE SIDE OF THE HIGHWAY BEFORE THE ENGINE/MOTOR STOPPED WITH NO POWER. WHEN I TURNED THE POWER ON/OFF SEVERAL TIMES THE ENGINE WOULD START BUT THERE WAS NO POWER. I DID NOTICE THAT ON ALL THREE STALLS MY GAS GAUGE WAS LOW (ONE OR TWO BARS) BUT I HAVE RUN THE CAR FOR THIRTY MILES AFTER THE LAST BAR STARTED TO FLASH SO IT'S HARD TO TELL IF THERE IS A CONNECTION. I DID REPORT THIS TO...

MY DAUGHTER WAS DRIVING MY 2004 PRIUS ON I35W AT 55 MPH WHEN SEVERAL RED WARNING LIGHTS CAME ON AND THE CAR CHIMED. WE WERE ABLE TO EXIT THE INTERSTATE AND LEFT THE CAR RUNNING WHILE WE CONSULTED THE OWNER'S MANUAL, THEN CALLED THE DEALER. WE STARTED TO DRIVE TO THE DEALERSHIP, BUT THE CAR'S POWER DIMINISHED NOTICEABLY AT EACH RED LIGHT OR STOP SIGN. IT FINALLY STALLED ABOUT ONE MILE FROM THE PARKING LOT WHERE WE HAD INITIALLY PAUSED. THE CAR WAS BLOCKING A BUS ROUTE/HIGHWAY EXIT/SURFACE STREET CONNECTOR AT THAT POINT. A BUS DRIVER AND PASSENGER HAD TO PUSH THE CAR TO A SAFER LOCATION, OUT OF THE BUS' WAY! THE IGNITION LOCKED AND THE FOB COULDN'T BE REMOVED UNTIL AT LEAST 30 MINUTES PASSED. THE CAR WAS TOWED TO THE DEALER, WHO SAID IT WAS "A SOFTWARE GLITCH" AND THAT THERE WAS NOTHING WE COULD HAVE DONE...
