Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1986 Mack Rw Series — too few to judge reliability from owner reports alone — but one recall campaign applies to this year, so any used example should have its VIN checked for completed recall work.

NCAP overall
1 NHTSA recall campaign on file. Recall repairs are free at franchised dealers.
Defect
ON RIGHT HAND STEERING ARM, KEYWAY MAY BE IN THE WRONG LOCATION CAUSING A TOGGLE CONDITION TO OCCUR UNDER CERTAIN CONDITIONS.
Consequence
THIS COULD RESULT IN SLOW STEERING RETURN WITHOUT PRIORWARNING WHICH WOULD AFFECT STEERING CONTROL AND CREATE THE POTENTIAL FOR ACRASH.
Remedy
REPLACE INCORRECT STEERING ARM.
The record is thin — 0 NHTSA complaints — so owner-report data can't strongly confirm reliability either way, though 1 recall should be verified as completed.
Yes — NHTSA lists 1 recall campaign affecting the 1986 Mack Rw Series. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
