Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1978 Dodge M400 — 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
POOR CLAMPING OF THE CARBURETOR FUEL INLET HOSE TO THE INLET TUBE AND CARBURETOR NIPPLE COULD ALLOW FUEL LEAKAGE TO OCCUR.
Remedy
DEALER WILL REPLACE THE SUSPECT FUEL INLET HOSE CLAMPS AND CHECK THE FUEL TUBE ROUTING TO ENSURE THAT IT IS SECURE.
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 1978 Dodge M400. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
