NHTSA Complaint #10662639 — 2011 TOYOTA SIENNA

HELLO, I OWN A 2011 SIENNA LE V6. IN COLD WEATHER, IT HAS A PROBLEM WHEN BRAKING WHERE THE VEHICLE LURCHES FORWARD AS IT COMES TO A STOP. THE DEALER DROVE THE CAR AND NOTED NO ISSUES. HOWEVER, AS YOU CAN SEE ON THIS INTERNET THREAD, MANY OTHER OWNERS HAVE THE SAME ISSUE. HTTP://WWW.SIENNACHAT.COM/FORUM/193-PROBLEMS-MAINTENANCE-REPAIR/158410-ENGINE-REVVING-UP-JUST-BEFORE-STOP.HTML THIS ISSUE IS NOT JUST ANNOYING, I BELIEVE IT IS A SAFETY ISSUE, PARTICULARLY ON SLIPPERY SURFACES SUCH AS SNOW AND ICE WHICH ARE LIKELY TO OCCUR IN THE COLDER WEATHER THAT PRECIPITATES THIS ISSUE. I BELIEVE EITHER THE ENGINE OR TRANSMISSION PROGRAMMING NEEDS TO BE MODIFIED TO ADDRESS THIS ISSUE AS SOON AS POSSIBLE. THIS OCCURS WHEN THE ENGINE IS AT HIGH SPEED IDLE AFTER A COLD STOP, WHICH CAN LAST FOR MANY MILES AFTER YOU START DRIVING. *TR
