NHTSA Complaint #10680271 — 2004 TOYOTA PRIUS

VEHICLE SLIPS INTO NEUTRAL AND/OR WILL NOT REVERT BACK TO DRIVE OR REVERSE. THE PROBLEM IS MOST PREVALENT WHEN WEATHER GETS EXTREMELY HOT (99 DEGREES +). THE ONLY WAY I WAS ABLE TO GET MOVING WAS TO PHYSICALLY HOLD MY SHIFTER IN DRIVE POSITION; THE SECOND I LET IT GO, THE VEHICLE AUTOMATICALLY REVERTED BACK TO NEUTRAL. I HAD MY VEHICLE OVER TO A LOCAL TOYOTA DEALERSHIP ABOUT THIS ISSUE. THE TECHNICIAN AT THAT TIME DID ACKNOWLEDGE THIS WAS STRANGE AND WITNESSED THE PROBLEM ON SITE. AFTER DIAGNOSING THE VEHICLE, HE COULD NOT FIND ANYTHING WRONG; I WAS TOLD TO LEAVE THE CAR WITH THE DEALERSHIP FOR A FEW DAYS TO TRY TO REPLICATE THE PROBLEM; NO OTHER MEANS OF TRANSPORTATION WAS OFFERED. I FELT IT WOULD HAVE BEEN AN UNFAIR EXPENSE TO RENT A CAR FOR AN UNDETERMINED AMOUNT OF TIME WHILE TOYOTA DIAGNOSED MY VEHICLE FOR SEVERAL DAYS; THAT SAID, I DID NOT RETURN TO THE SAME DEALERSHIP FOR THIS SPECIFIC MATTER. GIVEN THAT THIS SEEMS TO OCCUR ONLY IN EXTREME HOT WEATHER, YOU WOULD HAVE TO REPLICATE THE SAME ENVIRONMENTAL CONDITIONS TO DIAGNOSE IT. MOREOVER, GIVEN THE SPONTANEITY OF THIS ISSUE IT COULD TAKE A VERY LONG TIME TO DIAGNOSE IT. THIS IS TRULY A SAFETY CONCERN ESPECIALLY WHEN THE VEHICLE IS IN MOTION. I HAVE ATTACHED TWO YOUTUBE VIDEO LINKS THAT DEMONSTRATE THIS PROBLEM OTHER OWNERS ARE EXHIBITING WITH THIS SAME ISSUE THAT DEMONSTRATE THAT I'M NOT JUST AN ISOLATED CONSUMER WITH THIS ISSUE.
