ELECTRICAL SYSTEM

The hybrid water pump failed/ aka the inverter coolant pump. This was recalled years ago and has failed again. The previous owner of my car replaced it in 2013, so Toyota is refusing to replace it again, despite the fact that the part is faulty and has compromised the safety of my vehicle. This issue was diagnosed by a mechanic yesterday, error code P0A93. The master warning light, check engine light, brake light came on. The AC stopped working. The brakes nearly gave out on me driving on a bridge in New York City. This part was recalled. Toyota refuses to honor the recall a second time. They clearly did not properly engineer this part! It failed again! They should be responsible for fixing this issue.

ELECTRICAL SYSTEM

The car stopped moving while I was driving. The engine is functional but it will not engage the drivetrain. The dashboard lights up intermittently. Most of the time the dash is dark. The local Toyota dealer will not take this car into the service department since it is over 10 years old and the dealer has not done all the regular servicings of the car. So I can not drive it.

ELECTRICAL SYSTEM

My 2009 Toyota Prius abruptly lost power while driving. The electrical system turned off and the vehicle stalled while going 50 mph on a 2-lane parkway. While I was able to put my hazard lights on and steer the vehicle, I had no other control and was at a high risk of a crash. There's no emergency lane and few areas wide enough to pull over on the parkway. I was forced to coast the vehicle until I could pull off the parkway onto a patch of grass off the busy road. There were no warnings, messages, or other symptoms of the problems prior to failure. I had plenty of gasoline in the tank, so it wasn't due to a lack of fuel. The car would not start after pulling over and I had to get towed. After researching the issue, it sounds very similar to the safety recall involving certain 2013-2015 Model Year Prius and 2014 – 2017 Model Year Prius v in the United States, the press release for which was published on June 24 2020: https://tinyurl.com/4mrnz9nr Furthermore, the Los Angeles Times wrote an article on April 23 2018 about a similar issue, referring to a recall in 2014 which was intended to fix overheating problems in the 2010-204 Prius inverter. Those recall documents suggest that Toyota has been tracking this issue with the inverter since 2011. https://tinyurl.com/afwvt2sc A sudden power loss is generally considered a serious safety defect. I could have gotten into a serious car accident today and injured myself or other drivers. The 2009 Toyota Prius model had a recall issued on recall date: 11/14/2012 under NHTSA Campaign ID: 12V536000, referring to a "short circuit between coil wires and a possible open fuse, creating a stall-like condition of the hybrid system while the vehicle is being driven. This may increase the risk of a vehicle crash." At this time, I don't believe Toyota has conducted due diligence into ensuring the safety of the 2009 Toyota Prius model. The vehicle has not yet been inspected by the manufacturer or insurance reps.

WE HAVE A 2009 PRIUS WHICH STALLED ON THE FREEWAY AS MY HUSBAND WAS DRIVING IT YESTERDAY (10/16/2020). LUCKILY, EVEN THOUGH IT WAS A BUSY AUSTIN FREEWAY, MY HUSBAND WAS ABLE TO MANEUVER IT TO THE SHOULDER AND CALL AAA TO TOW THE CAR TO THE SERVICE STATION. ON INSPECTION, WE WERE TOLD THAT THE REASON FOR THE STALL WAS THE FAILURE OF THE INVERTER DRIVE PUMP ALONG WITH THE 12V BATTERY ON BOARD. THIS CAR WAS PART OF THE RECALL FOR THE INVERTER DRIVE PUMP AND THAT WAS REPLACED BY AN AUTHORIZED TOYOTA SERVICE CENTER IN 2013 FOR A SIMILAR ISSUE. ON THE OCT 16TH, 2020, THERE WERE NO WARNING LIGHTS - NO ENGINE CHECK LIGHT AND NOT EVEN THE 'MAINTENANCE REQUIRED' LIGHT - THE CAR TURNED ON JUST FINE, MY HUSBAND WAS ABLE TO DRIVE IT 5 MILES TO THE FREEWAY, GET ON THE FREEWAY AT 60 MPH AND DRIVE A FEW MILES ON IT BEFORE LOSING ALL POWER IN THE CAR. THE SERVICE TECH INFORMS US THAT THE INVERTER PUMP CAN BREAK DOWN DUE TO JUST REGULAR DRIVING - BUT THERE WAS ZERO INDICATION THAT THIS UNIT, WHICH APPARENTLY IS CRUCIAL TO THE CAR WHILE BEING DRIVEN, WAS IN ANY DANGER OF IMMINENT FAILURE. I DO NOT KNOW IF THIS PART IS EXAMINED OR SERVICED AS PART OF REGULAR MAINTENANCE, BUT NO WARNINGS WERE RAISED WHEN THIS CAR WAS LAST SERVICED, AT AN AUTHORIZED TOYOTA SERVICE STATION IN DEC OF 2019.

THE MULTI-FUNCTION DISPLAY (MFD) STOPPED WORKING AROUND 200K. AT FIRST, THE SCREEN WOULD NOT RESPOND TO TOUCH, THEN IT WOULD FREEZE OR APPEAR FUZZY, THEN THE DISPLAY HAD STATIC OR WOULD GO ON AND OFF, NOW IT IS JUST BLACK, WITH THE RARE INCIDENT (EVERY COUPLE OF MONTHS, USUALLY WHEN IT IS COLD OUTSIDE) WHERE THE MFD DISPLAYS A WHITE SCREEN OR GRAY SCREEN WITH LINES THROUGH IT. AS MANY OF THE VEHICLES FEATURES (REAR CAMERA, A/C, RADIO, ODOMETER, MILEAGE, ETC.) ARE CONTROLLED THROUGH THE MFD, I HAVE BEEN UNABLE TO UTILIZE THESE FEATURES. ON OTHER MESSAGE BOARDS (PRIUSCHAT) THIS APPEARS TO BE A RATHER COMMON PROBLEM AND SHOULD WARRANT SOME SORT OF CORRECTIVE ASSISTANCE FROM THE MANUFACTURE.

OUR PRIUS STARTED MAKING THIS NOISE RECENT... 4 SECONDS OF SPINNING CLICKING, THEN QUIET FOR 5 SECONDS THEN REPEAT. HAPPENS WHILE DRIVING, WHILE PARKED AND I JUST WENT OUT THERE WITH MY KEYS IN MY POCKET AND OPENED THE DOOR AND IT STARTED MAKING THE NOISE WHEN THE ENGINE STARTS...SO DOES THE RATTLING AND KNOCKING SOUNDS. WHEN I HIT ON BRAKE, THE BRAKE MAKES VERY ANNOYING NOISE.

ELECTRICAL SYSTEM

COMPLETE SHUTDOWN OF PRIUS AUTOMOBILE WITH NO WARNING WHILE IN MOTION ON A CITY STREET. ROLLED TO A STOP IN SAFE AREA. NOTHING WORKED EXCEPT EMERGENCY BLINKERS. NO INSTRUMENTATION OR WARNING LIGHTS APPEARED. THE CAR WAS LOCKED IN FWD PARK AND COULD NOT BE TOWED BY FLATBED TOW TRUCK AS THERE IS NO OVERRIDE. LIFT TOW TRUCK WAS USED TO GET TO DEALER. DIAGNOSED AS MELTED HYBRID INVERTOR PUMP. DEALER REPLACED PUMP AND FUSE FOR A $641.47 COST TO ME. IF THIS HAD HAPPENED ON A HIGHWAY/FREEWAY IT WOULD HAVE BEEN A DISASTER. THE COMPLETE LOSS OF POWER WITHOUT WARNING AT FREEWAY SPEED COULD VERY EASILY ENDED UP AS A MULTIPLE CAR PILE UP. JUST THE THOUGHT OF CROSSING MULTIPLE LANES IN TRAFFIC WITH NO POWER, JUST ROLLING, MAKES ME THINK IT'S TIME TO GET RID OF THIS CAR.

MY HEADLIGHTS KEEP RANDOMLY TURNING OFF ON THEIR OWN WHILE PARKED OR DRIVING, IN THE DARK OR THE LIGHT. TO TROUBLESHOOT I HAVE REPLACED THE HEADLIGHTS AND TIGHTENED THE WIRE CONNECTIONS, BUT THE PROBLEM CONTINUES. ONLY TURNING THE HEADLIGHTS OFF AND BACK ON SEEMS TO TEMPORARILY FIX THE PROBLEM...UNTIL THE NEXT TIME IT TURNS ITSELF OFF. I HAD A SIMILAR PROBLEM WITH MY HONDA PILOT 2005 A FEW YEARS AGO AND THERE WAS A SAFETY RECALL ON THE HEADLIGHT WIRE HARNESS KIT THAT WAS CORRODED FROM HUMIDITY AND OVERHEATING AND FAILING. THIS HAS NOW HAPPENED DOZENS OF TIME ON MY PRIUS, MOSTLY AFFECTING THE LEFT HEADLIGHT ONLY, BUT A COUPLE TIMES ON BOTH HEADLIGHTS.

I WAS DRIVING MY 2009 TOYOTA PRIUS ON A VERY COLD DAY (ROUGHLY 10 TO 20 DEGREES F). THE RED BRAKE WARNING LIGHT WAS ON, ALONG WITH THE ABS, VCS AND YELLOW "!" LIGHTS. THE BRAKES WERE EXTREMELY SOFT FOR ABOUT THE FIRST 5-10 MINUTES OF OPERATION. I WOULD PUSH THE BRAKE PEDAL AS FAR AS IT WOULD GO (IT WOULD NOT GO ALL THE WAY TO THE FLOOR) AND THE BRAKES WOULD SEEMS TO BE ENGAGING AT ABOUT 30%-50% OF THEIR NORMAL STOPPING POWER. AFTER THE VEHICLE WARMED UP, THE WARNING LIGHTS ON THE DASH WENT AWAY AND THE BRAKES BEGAN OPERATING NORMALLY. THE FOLLOWING WEEK, MY WIFE WAS DRIVING THE VEHICLE ON ANOTHER VERY COLD DAY (AGAIN PROBABLY ABOUT 10 DEGREES). SHE STATED THAT THE ABOVE MENTIONED LIGHTS STAYED ON FOR HER ENTIRE COMMUTE (LESS THAN 10 MINUTES) BUT THAT WHEN SHE ARRIVED TO WORK, HER BRAKES WERE NOT WORKING. SHE DESCRIBED THAT SHE PRESSED THE BRAKE PEDAL AS FAR AS IT WOULD GO, BUT THE BRAKES DID NOT SEEM TO BE FULLY ENGAGING. SHE STATED THAT SHE NEARLY HIT A WALL AS SHE WAS PULLING INTO THE PARKING LOT AT HER WORK. I HAVE FOUND SIMILAR ISSUES LISTED ON PRIUS FORUMS ONLINE. PERHAPS IT IS A ELECTRICAL OR COMPUTER PROBLEM AS OPPOSED TO A PROBLEM WITH THE BRAKES. WE HAVE NEVER HAD THE PROBLEM WHEN THE TEMPERATURE WAS ABOVE 25 DEGREES.

ALL OF THESE ITEMS I HAVE MENTIONED ALL OCCURRED WHILE I WAS DRIVING THE CAR.

DISPLAY FOR ODOMETER, SPEEDOMETER AND GAS GAUGE GOES OUT INTERMITTENTLY.THE 'COMBINATION METER' (A.K.A. 'INSTRUMENT PANEL' OR 'CLUSTER', THE THING YOU'RE LOOKING AT IN FRONT OF YOU) IS BAD. THERE ARE SEVERAL ELECTRICAL COMPONENTS IN THE CIRCUIT BOARD THAT CONTROL HOW IT 'POWERS UP', AND THEY FAIL. LACKING THE ABILITY TO POWER UP, THE DISPLAY GOES BLACK. JOE MYERS QUOTED US $1156 FOR REPAIR, AND ONE WEEK REPAIR TIME. SERVICE ADVISOR SAID THAT REPAIR PART IS FIXED PART SO THAT PROBLEM WILL NO LONGER OCCUR. WE MUST DRIVE THE VEHICLE TILL WE REPLACE IT. NO OFFER WAS MADE TO PROVIDE A LOANER CAR IF 07 PRIUS WENT INTO SHOP FOR REPLACEMENT CLUSTER. IT IS REALLY UNSAFE TO DRIVE WITHOUT KNOWING SPEED THAT CAR IS TRAVELING. AND WE WOULD NOT KNOW GAS LEVEL. WHO WANTS TO RUN OUT OF FUEL? VERY UNSAFE. WHY ISN'T TOYOTA OWNING UP TO THIS DEFICIENCY? SHOULDN'T IT BE A RECALL REPAIR? WE ARE THE ORIGINAL OWNER AND WE HAVE TAKEN THE VEHICLE INTO THE DEALERSHIP SERVICE SHOP FOR REPAIRS SINCE WE PURCHASED THE VEHICLE.

IF MY CAR SITS IN THE SUN, ON OCCASION THE AUDIO CONTROLS - AM/FM, VOLUME, POWER, TRACK SELECTOR, ETC. FAIL TO FUNCTION (THEY ARE UNRESPONSIVE). IF THE CAR IS TURNED OFF, THEN BACK ON, THEY WORK. THIS IS NOT A SAFETY CONCERN, PER SE. MY CONCERN IS NOT THE AUDIO PORTION NOT WORKING, BUT THE SYSTEM DESIGN AND QUALITY OF COMPONENTS. WERE THESE SAME COMPONENTS USED ELSEWHERE IN THE CAR? I'VE ONLY SEEN THIS HAPPEN WHEN MY CAR HAS BECOME HOT SITTING (NOT RUNNING) DUE TO THE WEATHER. USUALLY WHEN I PARKED FACING WEST AND THE SUN HAS BEEN HITTING THE FRONT OF THE CAR ALL DAY AND I LEAVE FROM WORK. THIS HASN'T HAPPENED IN THE PAST 2-3 YEARS BECAUSE I'VE KEPT MY CAR OUT OF THE SUN WHEN PARKING. IT OCCURRED BETWEEN 2012 AN 2014. I DO NOT HAVE AN EXACT DATE OF WHEN IT OCCURRED EVEN THOUGH YOUR FORM FORCES ME TO SPECIFY ONE.

I HAVE CONTACTED TOYOTA CONCERNING THE FAILURE OF A COMBINATION METER IN MY DAUGHTER'S 2007 PRIUS. THIS HAPPENED ON STARTUP. THIS ITEM IS RELATED TO THE DISPLAY SCREEN. AS MENTIONED IN THEIR WARRANTY POLICY BULLETIN NO: POL 12-05 DATED 10/12/12 A FAILURE CAN RESULT IN THE SCREEN GOING DARK. IF THIS HAPPENS IN THE NIGHT THIS CAN RESULT IN A SERIOUS SAFETY ISSUE BOTH BECAUSE OF THE UNEXPECTED AND IMMEDIATE DISTRACTION AND THE LOSS OF CRITICAL VISUAL INFORMATION. THEIR WARRANTY BULLETIN DOES NOT SEEM TO ADDRESS THE SERIOUSNESS OF THE MATTER. IT IS MY OPINION THAT THIS ITEM SHOULD BE AN IMMEDIATE RECALL. MY 2009 PRIUS IS ONE OF THOSE MENTIONED IN THEIR BULLETIN. THOUGH I HAVE NOT EXPERIENCED ANY FAILURE, I BECAME AWARE OF THIS ISSUE WITH THE RECENT EVENT THAT MY DAUGHTER EXPERIENCED. NEITHER I NOR MY DAUGHTER HAS RECEIVED ANY NOTIFICATION FROM TOYOTA. I AM A FAN OF THE PRIUS AS IS MY DAUGHTER, BUT THIS ISSUE IS TOO SERIOUS TO SIMPLY IGNORE. IT IS MY HOPE THAT THIS WILL BE ADDRESSED WITH TOYOTA.

MULTIFUNCTION DISPLAY FUNCTIONS INTERMITTENTLY. ORIGINALLY, PROBLEM ONLY APPEARED IN CONJUNCTION WITH COMBINATION METER FAILURE DURING COLD WEATHER STARTS. COMBINATION METER HAS BEEN REPLACED BY TOYOTA PER THEIR EXTENDED WARRANTY BUT MULTIFUNCTION DISPLAY PROBLEM PERSISTS. ON COLD STARTS IN THE MORNING THE UNIT DOES NOT FUNCTION. LATER IN THE DAY, AFTER SITTING IN THE SUN FOR A WHILE, THE UNIT WILL OCCASIONALLY START TO WORK BUT MIGHT GO ON/OFF AND RESET ITSELF WHILE DRIVING. ALL NAVIGATION MEMORY IS STILL THERE, INCLUDING AC SETTINGS BUT PHONE SETTINGS ARE WIPED OUT. THIS MULTIFUNCTION DISPLAY IS THE PRIMARY CONTROL FOR AC AND HEATER, NAVIGATION SYSTEM, TELEPHONE/BLUETOOTH, AUDIO, DIAGNOSTICS/MAINTENANCE, ETC. TOYOTA HAS INFORMED ME THAT THE UNIT IS DEFECTIVE AND NEEDS TO BE SENT TO THE MANUFACTURER (FUJITSU) FOR REPAIR. THIS APPEARS TO BE A WELL DOCUMENTED PROBLEM WITH THIS UNIT ON GEN 2 PRIUSES 2004-2009. THERE SHOULD BE AN EXTENDED WARRANTY ON THIS PIECE OF EQUIPMENT JUST LIKE THE EXTENDED WARRANTY ON THE COMBINATION METER.

HEADLIGHTS DON'T NEED TO BE REPLACED - THERE IS SOMETHING WRONG WITH CAR WIRING OR OTHER. I'VE HAD THIS CAR SINCE 2009 AND ONLY HAD PROBLEM LAST SIX MONTHS OR SO - PROBABLY STARTING 1/2016. CAR HAS APPROX. 65K MILES ON IT. VERY UNSAFE - ESPECIALLY AT NIGHT IN CITY WHEN I CAN'T FOLLOW ANOTHER CAR AND I CAN'T TELL IF MY HEADLIGHTS ARE ON OR NOT!
