I WAS TURNING LEFT ON COUNTRY ROAD AT 25MPH THE CAR DECELERATE AND YELLOW WARNING CAME ON THE DEALER SAID THE CAR THOUGHT IT WAS GOING TO ROLL OVER THEY DID THE SOFT WARE UP DATE THE CAR STILL DECALRATE YELLOW LIGHT COME ON MOST OF TIME WHEN STARTING UP

TAKATA RECALL (?) WE PURCHASED THIS VAN ON 4/18/2019, PREVIOUSLY THE VAN WAS A RENTAL. THE NEXT EVENING, GOING TO DINNER ON A FRIDAY NIGHT ABOUT 9 P.M. I WAS ON A 2 LANE ROAD IN A RURAL AREA, TRAVELING AT 60 MPH AND A DOG WALKED IN FRONT OF ME. I HAD NO TIME TO REACT. THE FRONT END OF THE VAN WAS LAYING IN THE ROAD, NOT DRIVABLE. AGAIN, A FRONT END COLLISION AND NO AIR BAG DEPLOYMENT! 2ND TOYOTA SIENNA, FIRST A 2017 AND NOW A 2018, BOTH RENTAL SALES, BOTH HAD FRONT END COLLISIONS AND BOTH HAD NO AIR BAG DEPLOYMENT. AT 60 MPH THERE'S NO REASONABLE EXCUSE FOR NO AIR BAG DEPLOYMENT.

TL* THE CONTACT OWNS A 2018 TOYOTA SIENNA. WHILE DRIVING APPROXIMATELY 45-50 MPH, THE ACCELERATOR PEDAL WAS DEPRESSED, BUT FAILED TO RESPOND. ADDITIONALLY, THE VEHICLE DECELERATED INDEPENDENTLY ON OCCASION. THE VEHICLE WAS NOT DIAGNOSED OR REPAIRED. LARRY H MILLER TOYOTA COLORADO SPRINGS (LOCATED AT 5115 NEW CAR DR, COLORADO SPRINGS, CO 80923, (719) 419-5832) WAS NOTIFIED OF THE FAILURE. THE CONTACT STATED THAT THE FAILURE RECURRED ON SEVERAL OCCASIONS. THE MANUFACTURER WAS NOT CONTACTED. THE APPROXIMATE FAILURE MILEAGE WAS 10,000. THE CONSUMER STATED THE WHILE BACKING OUT OF A PARKING SPACE, THE VEHICLE SUDDENLY STOPPED REVERSING AND THE ENGINE BEGAN TO REV UP AS IF THE GAS PEDAL WAS BEING DEPRESSED. THE VEHICLE WAS PUT INTO PARK AND BACK INTO REVERSE. THE ISSUE RESOLVED ITSELF. THE BRAKING SYSTEM WOULD SHUTTER WHEN IN SNOW OR ICE CAUSING THE VEHICLE TO VIBRATE VIOLENTLY AND LOSE TRACTION. *JS

2018 TOYOTA SIENNA LE. CONSUMER WRITES IN REGARD TO DELAYED ACCELERATION WHICH IS CAUSING TRANSMISSION DAMAGE. *AS *TR

3RD ROW POWER SEATS ARE MALFUNCTIONING AND ARE OPERATING WHILE VEHICLE IS IN MOTION. MULTIPLE TIMES, AND ON DIFFERENT DAYS, THE POWER SEATS HAVE STARTED TO CLOSE WHILE PASSENGER IS SEATED AND BUCKLED IN THE SEAT. OCCURRED TODAY WHILE ON THE HIGHWAY, AT HIGHWAY SPEED WHILE MY WIFE WAS SEATED IN THE DRIVERS SIDE 2 SEAT SPLIT. THE SEAT STARTED TO CLOSE ON ITS OWN - NO ONE TOUCHED ANY BUTTON AND WE HAD BEEN DRIVING FOR OVER AN HOUR. THE SEAT PUT PRESSURE ON HER UNTIL IT STOPPED IN A PARTIALLY CLOSED POSITION. THE SEAT BUTTONS THEN DID NOT WORK TO REOPEN THE SEAT BACK FOR SEVERAL MINUTES. THIS WOULD BE EXTREMELY DANGEROUS FOR A SMALL CHILD. THIS HAS HAPPENED IN A SIMILAR SCENARIO ON MULTIPLE OCCASIONS AND WE ARE CERTAIN THAT THE POWER SEATS ARE MALFUNCTIONING.

THE VAN STRUGGLES TO ACCELERATE. THERE IS NO WAY TO TURN OFF ECO MODE. NO BUTTON IS AVAILABLE. VAN STRUGGLES TO GO UP HILLS , EXCELERATE THRU INTERSECTIONS AND ALWAYS HUNTING FOR GEARS OR STUCK IN A GEAR AND SOUNDS AND ACTS VERY HEAVY ON POWER TRAIN END. THERE IS AN OPTION TO TURN OFF ECO LIGHT.TURNING OFF ECO LIGHT DOES NOTHING BUT HIDE THE PROBLEM. WE NEED AN OPTION TO COMPLETE DISABLE ECO MODE WITH UPDATE OR WITH A BUTTON.

1. EVEN TO GO ON A SMALL UPHILL SLOPE, THE VEHICLE(V6) REALLY STRUGGLES. AND WHEN I TRY TO ACCELERATE, IT KIND OF STALLS OR SLOWS DOWN FOR A MOMENT, THEN TRIES TO SPEED UP BUT ITS STILL VERY SLOW. I'M FACING THIS ISSUE EVERY DAY. MY OTHER CAR 2011 CAMRY(V4) IS VERY SMOOTH AT THE EXACT SAME PLACES. CANT BELIEVE THE PICKUP IS THIS POOR WITH A NEW CAR. 2. ON HIGHWAYS, JUST TO MAINTAIN THE SPEED OVER 65 MPH ON A RECENT TRIP, I HAD TO PRESS REAL HARD ON GAS THE WHOLE TIME, EVEN AFTER THAT, I CAN CLEARLY TELL THE VEHICLE WAS WORKING EXTRA HARD JUST TO BE OVER 65. THIS ISSUE IS CONSISTENT EVERY TIME I GO ON HIGHWAYS. MANY OWNERS HAVE REPORTED THE ABOVE ISSUES AT TOYOTA OWNERS FORUM: HTTPS://WWW.TOYOTA.COM/OWNERS/COMMUNITY/ASK-AN-OWNER/QUESTION-DETAILS/ID/62777282 BOTH ISSUE#1 AND 2 MIGHT LEAD TO/TRIGGER A BACK END COLLISION BECAUSE THE CARS COMING FROM BEHIND WONT KNOW THAT THE VEHICLE WILL SLOW DOWN (DUE TO POOR PICKUP) ALL ON A SUDDEN ON EVEN A SMALLER SLOPE. SAME WITH HIGHWAYS TOO AND GOT TAILGATED ON MANY OCCASSIONS ON HIGHWAYS. RECENTLY DID THE DIAGONOSTICS AT THE DEALERHSIP RECENTLY BUT THEY SAID EVERYTHING LOOKS GOOD.

I HAVE A QUESTION REGARDING VEHICLE SEAT MOVEMENT. I HAVE BEEN TOLD BY TWO DEALERSHIPS THAT THE SEATS IN THE THIRD ROW OF THE TOYOTA SIENNA ARE MEANT TO HAVE SOME PLAY TO THEM. MY MAIN CONCERN IS THAT WITH A COUPLE OF CAR SEATS IN THE THIRD ROW, OR A COUPLE OF PASSENGERS, THE MOVEMENT OF THE SEATS MAY BE AN ISSUE. ALL FOUR SEAT LATCHES ROTATE WHEN LIFTING ON THE SEAT BY HAND, ALLOWING THE SEAT TO TWIST, MOVE TO THE REAR OF THE VEHICLE AND MOVE LATERALLY. THIS WOULD BE LESS OF A CONCERN IF THE SEATS THEMSELVES WERE NOT THE MOUNT FOR THE LATCH SYSTEM AND SEAT BELTS. MY QUESTION IS, WHAT MOVEMENT IS ALLOWED OF THESE SEATS? IN AN ACCIDENT, A HUGE AMOUNT OF FORCE CAN BE EXERTED ON THESE LATCHES, AND IF THEY ALLOW PLAY, THAT FORCE CAN BE MULTIPLIED BY THAT MOVEMENT. THE INCREASE IN FORCE COULD POTENTIALLY CAUSE THE LATCHES TO FAIL. CURRENTLY THERE IS NO SAFETY TEST FOR THIRD ROW OCCUPANTS OR REAR END COLLISIONS, FROM WHAT I HAVE RESEARCHED. THE ATTACHED FILES SHOW THE ACCESSIBLE LATCHES, AND THEIR MOVEMENT WHEN FORCE IS APPLIED TO THE SEAT.
