What’s wrong with it?

LACK OF SUFFICIENT BRAKE POWER ASSIST WILL INCREASESTOPPING DISTANCE AND COULD RESULT IN A VEHICLE ACCIDENT.

DURING THE REMOVAL AND INSTALLATION OF THE AIR FILTER HOUSING WHILE SERVICING THE VEHICLE, IT IS POSSIBLE TO MISROUTE THE PREFORMED VACUUM HOSE AND DAMAGE THE CHECK VALVE IN THE VACUUM HOSE.

IF THE CHECK VALVE IS DAMAGED, LOSS OF SUFFICIENT BRAKE POWER ASSIST WILL OCCUR.

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.
