Out of nowhere my vehicle started making a whining noise and then stopped moving then all these lights popped on my Dash getting it towed to a shop to come to find out that the solenoids for the transmission had went bad thank goodness I was on a side road only doing 25 mph I couldn't imagine being on the freeway doing 65 when this happened there has been numerous numerous other reports have the same issue
CAR HAD UNEXPLAINED ACCELERATION. CAR HAD SOLENOID RECALL REPAIR. CAR WOULD SURGE FORWARD SLIGHTLY UNTIL ACCIDENT CAUSED IT TO GO OUT OF CONTROL. ALSO, TAKATA RECALL. CAR WAS FILLED WITH AIR BAG MATERIAL AND SIDE AIR BAGS CAUSED ALMOST FATAL INJURY TO MY WIFE AND SEVERE INJURY TO MY SON. CAR WAS TRAVELING ON SIDE STREET TRAVELING AROUND 30 MILES PER HOUR UNTIL IT SPED UP TO 68.4 MPH..
I WAS DRIVING MY SIENNA ON A 2 LANE TOWN ROAD AND WITHOUT WARNING SMELLED SMOKE. AS I WAS PULLING OVER CARS IN THE ONCOMING LANE WERE HONKING AT ME AS THEY SAW THE FIRE UNDERNEATH WHERE THE ENGINE IS. WHEN I PULLED OVER SMOKE ENTERED INTO THE CAR. I STEPPED OUT, HEARD A POP, AND NOW THE ENTIRE FRONT OF THE CAR WAS FULL ON FIRE. THE FIRE DEPARTMENT ARRIVED ON SCENE QUICKLY AND EXTINGUISHED THE FIRE. I FILED AN INCIDENT REPORT WITH TOYOTA. I RECEIVED A CALL FROM A MAN SAYING HE WAS HIRED BY TOYOTA TO INVESTIGATE THE FIRE AND REPORT BACK TO THEM. TO DATE, I HAVE RECEIVED ZERO COMMUNICATION FROM ANYONE AT TOYOTA REGARDING THIS SERIOUS MATTER.
I HAD A CATASTROPHIC OIL LEAK ALL OVER MY DRIVEWAY AND GARAGE. RESEACHED HISTORY OF THIS TYPE AND FOUND IT WAS IT WAS A RUBBER HOSE ASSOCIATED WITH OIL TRANSFER (ALSO CALLED THE V V T 1 ACTUATOR HOSE. A VOLUNTARY RECALL ON THIS PART ENDED IN 2013. I WILL HAVE IT FIXED BY A LOCAL CAR REPAIR SHOP BUT IF THIS IS A KNOWN PART FAILURE FOR YEARS, WHY WOULD TOYOTA NOT MAKE A MANDATORY RECALL OF THIS FAULTY PART? MY 2009 TOYOTA SIENNA WHICH I JUST PURCHASED 2 MONTHS AGO WILL NOW HAVE A MAJOR CAR REPAIR.
THE OIL COOLING HOSE POPPED WHILE DRIVING CAR. APPARENTLY THERE WAS A RECALL/SERVICE BULLETIN FOR THIS ISSUE INVOLVING OTHER TOYOTA AND LEXUS VEHICLES. FOR SOME REASON THERE WAS NONE ISSUED FOR THIS VEHICLE. NOW THERE IS ENGINE DAMAGE. TOYOTA DROPPED THE BALL ON THIS ONE. THEY NEED TO BE HELD LIABLE FOR THE DAMAGE.
TAKATA RECALL ! I WAS DRIVING TOYOTA SIENNA ON LOCAL STREET IN BOCA RATON WHEN CAR HAD UNEXPLAINED ACCELERATION. CAR STRUCK A TREE WHICH CAUSED THE AIR BAGS TO REACT. I HAD AIRBAGS STUFFING IN MY LUNGS WITH CONTUSION AND IN MY INTESTINES. MY SON HAD A BAD CONTUSION ON RIGHT SIDE FROM SIDE AIRBAG. MY WIFE HAD TO SPEND 17 DAYS IN A HOSPITAL BECAUSE CONTUSION ON LUNGS AND MULTIPLE BONES. THE FORCE NOT HER OUT OF HER SEAT ON FLOOR. HER SEAT BELT CUT INTO HER ABDOMEN. SHE ALMOST DIED FROM INJURIES AND INCOMPETENT MEDICAL CARE. MY DAUGHTER WAS SAVED FROM SEVERE INJURY BECAUSE THE SIDE AIRBAG DID NOT FUNCTION. THIS WAS A TERRIBLE HOLIDAY GIFT. *TR
WHILE DRIVING DOWN A VERY STEEP NARROW UNPAVED DRIVE THE ENGINE STOPPED. ALL LIGHTS ON THE DASH REMAINED ON BATTERY LIGHT WAS ON. STEERING WAS VERY DIFFICULT AND THE BREAKS WERE STIFF. WHEN I CAME TO A STOP I RESTARTED THE ENGINE.
2GR-FE ENGINE: CYLINDER # 2 VALVE SPRING BROKE.
2009 TOYOTA SIENNA. CONSUMER WRITES IN REGARDS TO ENGINE OVERHEATING. *SMD THE CONSUMER STATED HE REPLACED THE FAN RELAY AND THERMOSTAT. HOWEVER, THE VEHICLE CONTINUED TO OVERHEAT. THE DEALER REPLACED THE RADIATOR AND WATER PUMP, BUT THE OVERHEATING CONTINUED. THE DEALER INFORMED THE CONSUMER THEY LOOKED INTO THE CYLINDERS WITH A BORESCOPE AND SAW MARKS ON THE CYLINDER WALL WHICH LEAD THEM TO THE CONCLUSION THAT THE HEAD GASKETS WERE BAD AND THEY WOULD HAVE TO BE REMOVED AND SENT TO A MACHINE SHOP TO SEE IF THEY WERE WARPED AND THE CYLINDERS AND ENGINE BLOCK WOULD HAVE TO BE INSPECTED TO SEE IF THERE WAS AN ISSUE. *JB
THE CAR HAD AN ALIGNMENT PROBLEM AFTER 5000 MILES. FIRESTONE ALWAYS ALIGNED THE WHEELS BUT 1 WENT THROUGH 3 SETS OF TIRES. THE CAR WOULD SPEED UP THE LAST COUPLE OF MONTHS AFTER I TOOK MY FOOT OFF THE GAS PEDAL. THE BRAKES SEEMED TO WORK BUT THEY JUST DID NOT SEEM RIGHT. I NOTICED THE DAY AFTER I DROVE THE RAV4 THE DIFFERENCE FORM THE SIENNA. THE RAVE 4 ALSO JERKS SOMETIMES WHEN I STEP ON THE GAS PEDAL.
2009 TOYOTA SIENNA MINIVAN DEVELOPED CORRODED REAR AIR-CONDITIONING LINES AFTER ONLY 4 YEARS. CORROSION CAUSED COMPLETE LOSS OF A/C COOLANT. IT COST ME $118 TO HAVE THE A/C SYSTEM TESTED ONLY TO FIND OUT THAT IT WILL COST ME ANOTHER $1578 TO REPAIR THE PROBLEM...AND THERE'S NO GUARANTEE THAT THIS WON'T HAPPEN AGAIN IN ANOTHER 4 YEARS. DEALERSHIP WON'T HELP. TOYOTA CORPORATE WON'T HELP. IT IS A SCAM THAT THEY USE UNTREATED ALUMINUM A/C LINES THAT THEY ADMIT ARE PRONE TO CORROSION IN NORTHERN CLIMATES WHERE SALT IS USED ON THE ROADS. EASY FIX: PAINT THE A/C LINES! TOYOTA WON'T OFFER ANY HELP WHATSOEVER! I HAVE FOUND AN EMOTIONAL STATE BEYOND RAGE. *TR
2009 TOYOTA SIENNA. CONSUMER WRITES IN REGARDS TO VEHICLE FIRE *TGW THE CONSUMER'S INSURANCE COMPANY DETERMINED THAT OIL LEAKED FROM A FAULTY VALVE AND SEAL IN THE MANIFOLD COVER. HOWEVER, TOYOTA PROVIDED A DIFFERENT EXPLANATION AS TO HOW THE VEHICLE CAUGHT ON FIRE. THEY STATED THE FIRE WAS CAUSED BY SPILLED OIL AND OVERFILLING OF OIL. TOYOTA STATED THEY HAVE A PHOTO OF THE DIP STICK PROVING THAT THE OIL WAS OVERFILLED, BUT REFUSED TO PROVIDE THE PICTURE. *JB
I HAVE A 2009 TOYOTA SIENNA WITH ABOUT 37800 MILES ON THE ENGINE. THIS IS A CERTIFIED PRE-OWNED TOYOTA AND I BOUGHT IT WITH APPROXIMATELY 33000 MILES ON IT IN NOVEMBER OF 2010. AT ABOUT 37000 I NOTICED A TICKING NOISE COMING FROM THE ENGINE AT IDLE. IT STARTS AFTER THE ENGINE WARMS UP; MOSTLY AFTER DRIVING ABOUT 15 MINUTES. I TOOK IT TO A TOYOTA DEALER FOR A DIAGNOSIS AND THE DEALER STATED THEY HEARD IT AND IT'S ONLY NORMAL ENGINE SOUND. THERE IS A TSB 0094-09 THAT ADDRESSES THE ISSUE. HOWEVER, MY VEHICLE DOES NOT FALL WITHIN THE AFFECTED PRODUCTION CHANGE EFFECTIVE VIN ACCORDING TO THE TOYOTA DEALER. AS A MATTER OF FACT MY SIENNA WAS MANUFACTURED ABOUT 2000 VEHICLES AFTER THE AFFECTED PRODUCTION CHANGE EFFECTIVE VIN. I BELIEVE THE PROBLEMS RELATED TO TSB 0094-09 STILL EXIST BEYOND THE AFFECTED VINS IN THE TSB. TOYOTA SHOULD REALLY FIX THESE PROBLEMS. THE ENGINE LOUD TICKING NOISE THAT IS EASILY NOTICED IS NOT NORMAL. *TR
