NCAP overall
3 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
THESE HEAVY TRUCKS WERE EQUIPPED WITH EXHAUST MUFFLERS WITHOUT HEAT SHIELDING.
Consequence
SOMEONE WORKING BEHIND THE CAB COULD CONTACT THE HOT MUFFLER CAUSING PERSONAL INJURY. ALSO SOME OF THESE VEHICLES WERE EQUIPPED WITH DECK PLATES WITH NO GRAB HANDLES FOR ACCESS.
Remedy
DEALERS WILL INSTALL MUFFLER SHIELDS AND, WHERE NECESSARY, GRAB HANDLES.
Defect
AIR SYSTEM BLOCKAGE IN THE AIR DRYER OCCURS DEGRADING THE MOISTURE REMOVING CAPABILITIES OF THE DRYER WHEN THE VEHICLE IS OPERATED IN A COLD ENVIRONMENT AND MOISTURE ACCUMULATES AND FREEZES IN THE AIR DRYER OR IN THE LINE BETWEEN THE DRYER AND THE AIR SYSTEM RESERVOIR. THE AIR DRYER CAN BECOME OVER PRESSURIZED CAUSING THE AIR DRYER CARTRIDGE TO SEPARATE FROM THE MOUNTING BASE.
Consequence
IF THE AIR DRYER SEPARATES FROM THE BASE, THE CARTRIDGE CAN SEPARATE SUFFICIENTLY ENOUGH TO CAUSE PERSONAL INJURY OR PROPERTY DAMAGE.
Remedy
DEALERS WILL EQUIP AIR SYSTEMS WITH A PRESSURE RELIEF VALVE TO BE LOCATED BETWEEN THE COMPRESSOR AND THE AIR DRYER. THIS PRESSURE RELIEF VALVE IS INTENDED TO VENT IF EXCESSIVE PRESSURE DEVELOPS IN THE AIR DRYER.
Defect
STRAPS HOLDING THE SLEEPER UPPER BUNK IN THE RAISED POSITION CAN RELEASE WITHOUT WARNING.
Consequence
IF THE RESTRAINING STRAP RELEASES SUDDENLY, THEBUNK FALLS WITHOUT WARNING AND CAN STRIKE AN OCCUPANT SITTING IN THE LOWER BUNK CAUSING PERSONAL INJURY.
Remedy
DEALERS WILL REPLACE THE UPPER BUNK RETAINING STRAPS WITH AN IMPROVED AUTOMOTIVE SAFETY BELT STYLE DESIGN STRAP.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 3 recalls should be verified as completed.
