What’s wrong with it?

UNANTICIPATED FULL THROTTLE CONDITIONS CAN OCCUR,RESULTING IN A LOSS OF THROTTLE CONTROL AND POSSIBLE ACCIDENT.

THE ENGINE THROTTLE PLATE SHAFT CAN BECOME DISCONNECTED FROM THE THROTTLE LEVER ASSEMBLY.

THE HEX HEAD LOCKING SCREW BETWEEN THE THROTTLE STOP ASSEMBLY AND THE THROTTLE SHAFT CAN LOOSEN.

ALSO, THE HEX HEAD PINCH BOLT BETWEEN THE THROTTLE LEVER AND THE THROTTLE PLATE SHAFT CAN LOOSEN.

THE THROTTLE RETURN SPRING CONTROLS THE THROTTLE PLATE POSITION THROUGH THE THROTTLE LEVER.

IF EITHER SCREW LOOSENS, THE THROTTLE RETURN SPRINGS NO LONGER CONTROL THE THROTTLE PLATE POSITION.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Which ones, by part or lot: the recall’s report on NHTSA’s site gives them where the maker did; this file gives part numbers only where its maker listed them.
  • How many have been returned or fixed isn’t in the notice.
