What’s wrong with it?
THIS RUBBING MAY CAUSE THE HYDRAULIC LINE TO BE RUBBED THROUGH RESULTING IN A LEAK AND A LOSS OF HYDRAULIC FLUID. THIS FLUID COULD IGNITE IF IT COMES IN CONTACT WITH A HOT SOURCE.
ON CERTAIN TRANSIT BUSES, THERE IS A POSSIBILITY THAT THE HYDRAULIC LINE COMING FROM THE RADIATOR FAN MOTOR TO THE CAC MOTOR IS RUBBING ON THE CHASSIS.

- 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.
