What’s wrong with it?
The notice gives no hazard in a field of its own.
THE FRONT SUSPENSION CONTROL ARMS WERE ASSEMBLED WITH BALL JOINTS WHICH MAY CONTAIN SOCKETS THAT WERE NOT PROPERLY HEAT-TREATED.
THIS MAY CAUSE THE SOCKET TO WEAR RAPIDLY AND ALLOW THE BALL JOINT STUD TO SEPARATE FROM THE SOCKET, CAUSING EITHER THE LEFT OR RIGHT WHEEL SUSPENSION TO COLLAPSE.

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.
