2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
VEHICLE DESCRIPTION: CLASS 8 HEAVY DUTY TRUCKS. THE AIR SUSPENSION CONTROL VALVE SUPPLY LINE WAS NOT PLUMBED THROUGH AN AIR PRESSURE PROTECTION VALVE. IN THE EVENT OF A FAILURE, THERE WOULD BE LOSS OF AIR PRESSURE IN THE 'B' SYSTEM AIR RESERVOIR THAT SUPPLIES AIR PRESSURE FOR THE FRONT STEER AXLE BRAKES.
Consequence
THIS CONDITION WOULD RESULT IN INCREASED STOPPING DISTANCES.
Remedy
DEALERS WILL INSTALL THE NECESSARY AIR PRESSURE PROTECTION VALVE.
Defect
AXLE SEAT USED ON REAR AXLE MAY BE TOO HARD (BRITTLE) AND COULD CRACK.
Consequence
THE AFFECTED AXLE WOULD BE LOOSE, AFFECTING STEERING ANDDIRECTIONAL CONTROL, WHICH COULD RESULT IN LOSS OF VEHICLE CONTROL AND ANACCIDENT.
Remedy
REPLACE SUSPECT AXLE SEAT.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 2 recalls should be verified as completed.
