What’s wrong with it?

FAILURE OF THE SIDE MARKER/DIRECTIONAL LIGHTS TO ILLUMINATE WILL RESULT IN DECREASED VISIBILITY OF THE BUS AND/OR ITS INTENDED DIRECTION OF TRAVEL TO OTHER DRIVERS WHICH COULD INCREASE THE RISK OF A CRASH.

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.
