What’s wrong with it?

INADEQUATE WELD POSITIONING COUPLED WITH RADIUS ROD LOAD AND LOOSENING OF THE SPRING CLIP NUTS COULD CAUSE SPRING SEAT FRACTURE.

THIS CAN RESULT IN LOSS OF DIRECTIONAL CONTROL OF THE AXLE.

What the record doesn’t say

  • NHTSA’s recall file doesn’t say whether anyone was hurt.
  • Whether one vehicle or seat has been fixed: only its maker, or NHTSA’s lookup with a VIN, can say.
  • This recall names only model years before 2015, which have no pages here. Your VIN, at NHTSA, says which recalls are open on a vehicle.
  • How many have been returned or fixed isn’t in the notice.
