What’s wrong with it?
The notice gives no hazard in a field of its own.
SOME OF THE INVOLVED VEHICLES MAY HAVE AN INSUFFICIENT WELD FILLET SIZE ON THE REAR AXLE SUSPENSION PERCHES WHICH MAY CREATE A CONDITION WHEREBY THE PERCHES COULD BREAK OFF.

What should you do?
THE DEALER WILL INSPECT AND REWELD THOSE AXLE PERCHES WITH INSUFFICIENT WELDS, SO THAT WELD MATERIAL EXTENDS COMPLETELY TO THE EDGE OF THE PERCH. THIS WILL BE DONE AT NO COST TO OWNER.

- 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.
