AUTOMATIC SLIDING DOOR STRUCK THE CONSUMER WHEN CLOSING. DOOR WILL NOT STOP EVEN WITH TOTAL PRESSURE. DEALER DUPLICATED THE PROBLEM, AND COULD NOT STOP THE DOOR. *AK THE VEHICLE DOOR WILL ONLY STOP SLIDING WHEN PRESSURE IS PUT ON IT FROM THE OUTSIDE PART OF THE DOOR.

ON TWO SEPARATE OCCASIONS VEHICLE HESITATED WHEN APPLYING THE ACCELERATOR PEDAL FROM A STOP POSITION. VEHICLE TAKEN TO THE DEALER ON TWO SEPARATE OCCASIONS, AND THEY WERE UNABLE TO DUPLICATE THE PROBLEM. *AK

HESITATION OF 2004 TOYOTA SIENNA XLE LIMITED. VEHICLE HAS A SIGNIFICANT DELAY IN ACCELERATION WHEN APPLYING GAS FROM A SLOW ROLL (UNDER 5 MPH). THIS IS A RECURRING PROBLEM THAT IS NOT ADDRESSED BY TOYOTA.*AK

I COULD NOT SHIFT OUT OF PARK UPON STARTING THE ENGINE AND THE VSC AND ABS LIGHT CAME ON, I HAD TO SET AND RELEASE THE EMERGENCY BRAKE AND THE BRAKE PEDAL RANDOMLY THEN RE-ATTEMPT TO SHIFT OUT OF PARK WHICH WOULD THEN ENABLE ME TO SHIFT INTO DRIVE OR REVERSE. *AK

MANUFACTURER RECOMMEND THEY GO TO ARBITRATION. *AK THE CONSUMER BELIEVES THE MANUFACTURER NEEDS TO REDESIGN THE SEAT BELT BECAUSE THE FIX ONLY ALLEVIATES THE PROBLEM TEMPORARILY. *NM EA05-010.PCO

ACCELERATOR FAILS TO RESPOND FOR 1-2 SECONDS IN AN EMERGENCY ACCELERATION SITUATION. WHEN ENTERING A ROAD FROM A STOP SIGN, I HESITATED THINKING THERE WAS NO ROOM. A VEHICLE LET ME IN. WHEN I HIT THE ACCELERATOR TO MAKE IT SAFELY, THE VEHICLE FAILED TO RESPOND FOR 1-2 SECONDS. THE CAR LETTING ME SLOWED DOWN TO LET ME IN, BUT NOT ENOUGH TO ALLOW FOR THIS DELAY AND HE NEARLY REAR-ENDED ME. IT WAS SCARY TO NOT HAVE THE CAR RESPOND. I HAVE SEEN MANY OTHER COMPLAINTS FILED ABOUT THIS AND THE DEALER RESPONSE ALWAYS SEEMS TO BE THAT THIS IS HOW THE ELECTRONIC THROTTLE CONTROL PERFORMS. I BELIEVE THIS NEEDS TO BE RECALLED SO THAT TOYOTA CAN MAKE THIS ELECTRONIC DEVICE RESPOND IMMEDIATELY AS OPPOSED TO TAKING 1-2 SECONDS.*AK

THIS IS AN ONGOING PROBLEM. ON OUR 2004 TOYOTA SIENNA VAN, THERE IS A "DEAD SPOT" WHEN ATTEMPTING TO ACCELERATE FROM A SLOW COASTING CONDITION. THE PROBLEM DOES NOT OCCUR WHEN STARTING FROM A COMPLETELY STOPPED CONDITION. HOWEVER, IF COASTING AT APPROXIMATELY 5 - 10 MPH, DEPRESSING THE ACCELERATOR PEDAL YIELDS NO RESPONSE. NATURALLY I TEND TO DEPRESS THE ACCELERATOR FURTHER TO OVERCOME WHATEVER INERTIA IS HAPPENING, AND WHEN THE ENGINE/DRIVETRAIN FINALLY RESPONDS (SOMETIMES SEVERAL SECONDS LATER) THERE IS A PRONOUNCED JERK AS EVERYTHING CATCHES. WE HAVE HAD A FEW SITUATIONS WHERE COMPETING TRAFFIC CONDITIONS WARRANTED FIRM ACCELERATION AND WERE AT THE MERCY OF OTHER DRIVERS WHEN OUR VEHICLE FAILED TO PERFORM. BEING IN A NORTHERN CLIMATE, I AM ALSO GREATLY CONCERNED THAT DURING ICY CONDITIONS, THE RESULTING "JERK" WHICH OCCURS FOLLOWING THE LAG WILL RESULT IN BREAKING TRACTION AND SUBSEQUENT SKIDDING. IT SHOULD BE EMPHASIZED THAT FAILURE TO ACCELERATE WHEN NECESSARY IS ARGUABLY JUST AS DANGEROUS AS FAILURE TO STOP, AND THE PROBLEM NEEDS CORRECTED. THUS FAR, OUR DEALERSHIP ACKNOWLEDGES THE PROBLEM AND CLAIMS THAT IT'S A "NORMAL" BEHAVIOR FOR THIS DRIVETRAIN.

MY WIFE WAS IN AN ACCIDENT WHILD DRIVING OUR NEW, 2004 (3400 MILES) TOYOTA SIENNA. WE BELEIVE THAT THE CAUSE OF THE ACCIDENT WAS ANTILOCK BRAKE FAILURE.*AK THE CAR WAS TRAVELING AT 15 MILES PER HOUR. SHE WENT FROM ACCELLERATOR TO BRAKES AND THE BRAKES NEVER APPLIED. SHE SLAMMED INTO THE CAR THAT WAS IN FRONT OF HER. WE HAVE TRIED REPEATIDLY TO CONTACT TOYOTA BUT THEY HAVE NEVER CALLED US. THE DEALER IS NOT PROVIDING US ANY ASSISTANCE AND ARE DISMISSING OUR ASSERTIONS AS REDICULOUS. PLEASE HELP US.
