Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1983 Grumman Kubvan Trucks — too few to judge reliability from owner reports alone — but 3 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

NCAP overall
3 NHTSA recall campaigns on file. Recall repairs are free at franchised dealers.
Defect
A COTTER PIN THAT RETAINS THE NUT HOLDING THE REAR WHEEL BEARING TO THE AXLE ROD MAY BE MISSING. CONSEQUENCE OF DEFECT: THE NUT COULD LOOSEN ALLOWING THE BEARING TO SLIDE OFF THE AXLE AND THE WHEEL TO COME OFF. THIS COULD RESULT IN A VEHICLE ACCIDENT.
Remedy
INSTALL THE COTTER PINS, IF MISSING.
Defect
VACUUM LINES THAT HELP IN THE OPERATION OF THE POWER BRAKING SYSTEM MAY COLLAPSE UNDER VACUUM PRESSURE. VEHICLE DOES NOT COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 106, "BRAKE HOSES", SINCE VACUUM LINES CONTAIN MATERIAL WHICH IS NOT CERTIFIED FOR THEIR APPLICATION.
Remedy
DEALER WILL REPLACE HOSE WITH ONE THAT COMPLIES WITH THE SAFETY STANDARD.
Defect
IN THE EVENT OF A COLLISION, VEHICLE MAY LEAK FUEL WHEN ROLLED TO AN INCLINATION OF LESS THAN 45 DEGREES. ALTHOUGH A VENT VALVE IS PRESENT, THE VALVE CLOSES ONLY WHEN THE VEHICLE ANGLE EXCEEDS 45 DEGREES. THIS DOES NOT COMPLY WITH THE REQUIREMENTS OF FEDERAL MOTOR VEHICLE SAFETY STANDARD NO. 301, "FUEL SYSTEM INTEGRITY."
Remedy
DEALER WILL REPLACE THE VENT HOSE WITH ONE OF AN IMPROVED DESIGN. THE VENT HOSE WILL BE REROUTED TO A POSITION ABOVE THE MAXIMUM FUEL LEVEL AND WILL DISCHARGE INTO THE FUEL TANK FILLER PIPE.
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.
Yes — NHTSA lists 3 recall campaigns affecting the 1983 Grumman Kubvan Trucks. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
