What’s wrong with it?

The notice gives no hazard in a field of its own.

INCORRECT INNER WHEEL BEARINGS WERE INSTALLED IN THE REAR AXLES WHICH WEARS A GROOVE IN THE SPINDLE DUE TO A POOR FIT.

CONSEQUENCE OF DEFECT: A DEEP GROOVE COULD CAUSE THE AXLE HOUSING TO BREAK AND RESULT IN A VEHICLE CRASH WITHOUT PRIOR WARNING.

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.
