NCAP overall
2 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
THE 19.5 X 6 FRONT STEEL WHEEL DISC CRACKS OUTSIDE THE MOUNTING BOLT CIRCLE AND ENDS AT THE HUB'S DIAMETER.
Consequence
IF THE CRACKING GOES UNNOTICED, THE CENTER PORTION OF THEDISC WILL CRACK COMPLETELY AND EVENTUALLY THE RIM PORTION OF THE WHEEL COULDSEPARATE FROM THE CENTER SECTION WHICH COULD RESULT IN A VEHICLE CRASH.
Remedy
REPLACE ALL SIX (SEVEN IF THERE IS A SPARE) DEFECTIVE WHEELS WITH NEWLY DESIGNED WHEELS.
Defect
BRAKES MAY HAVE MISSING REAR AXLE OUTER BEARING RETAINING RING AND OR GREATER THAN SPECIFIED BEARING END PLAY. EITHER CONDITION ALLOWS THE ROTOR AND HUB ASSEMBLY TO SHIFT POSITION RELATIVE TO THE SPINDLE. THIS MOVEMENT CAN CAUSE BRAKE CALIPER PISTON RECEDE FARTHER THAN NORMAL INTO THE PISTON BORE WHICH WOULD REQUIRE GREATER THAN NORMAL BRAKE FLUID DISPLACEMENT WHEN THE SERVICE BRAKES ARE APPLIED.
Consequence
THIS CONDITION LEADS TO INCREASED STOPPING DISTANCE, ANDSHOULD MINIMUM STOPPING DISTANCE BE REQUIRED, IT COULD RESULT IN AN ACCIDENTWITHOUT WARNING.
Remedy
REPLACE BOTH REAR AXLE HUBS.
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.
