Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1979 Grumman Kurbmaster — 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
THE ENGINE BOX ON SOME UNITS MAY HAVE BEEN INCORRECTLY MANUFACTURED, CAUSING IT TO PROTRUDE PAST THE TOE BOARD FLANGE. THIS PROTRUSION COULD HINDER THE MOVEMENT OF THE DRIVER"S RIGHT FOOT FROM THE ACCELERATOR PEDAL TO THE BRAKE.
Remedy
DEALER WILL INSPECT AND, IF NECESSARY, CORRECT THE PROBLEM WITH A REPAIR KIT WITHOUT CHARGE TO OWNER.
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 1979 Grumman Kurbmaster. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
