2010 Toyota SIENNA problems and owner complaints

AT VEHICLE START- COLD AMBIENT TEMPS -APPROX 20F AND LOWER, ENGINE GOES TO ABOUT 1800 RPM AND STAYS THERE FOR ABOUT 2 MINUTES BEFORE DROPPING DOWN TO ABOUT 1100 RPM. AFTER SHFITING AND THE DRIVER TAKING THE FOOT OFF THE BRAKE PEDAL THE VEHICLE HAS A TENDENCE TO LURCH DUE TO THE HIGH ENGINE SPEED. THIS IS A SURPRISE EVENT EVERY TIME I OR MY WIFE START THIS VEHICLE AND I CONSIDER IT A SAFETY RELATED ISSUE. AS A COMPARISON, MY 2003 CHEVY TRAILBLAZER COLD ENGINE RPM NEVER GOES ABOVE 900 RPM AND DOES NOT EXHIBIT THIS LURCH TENDENCY. I COMPLAINED…

I WAS DRIVING IN LIGHT SNOW AT A SLOW SPEED (10-15 MPH) DOWN A VERY SLIGHT HILL (5 DEGREES). I TRIED TO COME TO A STOP, ONCE AT A TRAFFIC LIGHT AND ONCE AT A STOP SIGN, AND THE BRAKES COMPLETELY FAILED. THEY MADE A GRINDING NOISE, BUT DID NOT SLOW THE CAR WHATSOEVER. LUCKILY I DID NOT HIT OR WAS HIT BY ANOTHER CAR, BUT INCIDENT WAS VERY FRIGHTENING. I HAVE NOT YET SCHEDULED TO TAKE THEM IN FOR A SERVICE CHECK. *TR

I BOUGHT A 2010 TOYOTA SIENNA CE FROM SOUTHBAY TOYOTA IN GARDENA, CA AT ON JANUARY 24, 2010. AFTER MY WIFE DROVE IT FOR A WEEK, SHE FOUND THE CAR STARTED TO MAKE "CRACKING" SOUND NEAR THE STEERING WHEEL AREA ESPECIALLY WHEN THE CAR IS IN REVERSE DRIVING AND MOVING THE STEERING WHEEL SLOWLY. I TESTED IT AND THE ABNORMAL SOUND REPEATED EVERY TIME. I BROUGHT THE CAR TO SOUTHBAY TOYOTA A WEEK AGO, THEY DIDN'T IDENTIFY THE PROBLEM SINCE THE STREET IS SO NOISY. MY WIFE CONTINUED TO DRIVE THE CAR AND THE "CRACKING NOISE" BECAME LARGER AND AT THE SAME …

THIS IS THE SECOND TIME I HAD TO REPLACE MY TRANSMISSION IN MY SIENNA. EACH TIME IT HAPPENED, I WAS ON VACATION. THE FIRST TIME I REPLACED IT WAS LESS THAN 2 YEARS AGO, APRIL 2014.

We recently had a full diagnostic check done on our vehicle (199 point at Parkway Automotive in Little Rock, Arkansas) that listed some components in need of repair. The only part involving the electrical system needing repair was our battery which was testing as no longer holding enough charge. We took the vehicle to Sam's Club in North Little Rock, AR within the last 2-3 weeks and had the battery replaced with a new Duracell with 3 year warranty. We drove away with no issues with the vehicle and used it for local driving without issues for t…
