Limited data — recalls on file
NHTSA has just 0 complaints on file for the 1990 Peterbilt 372 — 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.
Consequence
THIS COULD RESULT IN MELT DOWN OF SURROUNDING PLASTICHOUSING AND POSSIBLE IGNITION OF THE MELTED MATERIAL, RESULTING IN A FIRE.
Remedy
REPLACE BLOWER SWITCH RESISTOR WITH RESISTOR WITH FUSIBLE LINK, AND RELOCATE THE RESISTOR TO A LOCATION WITH INCREASED FLOW OF COOLING AIR.
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 1990 Peterbilt 372. Recall repairs are free at franchised dealers; check the VIN at nhtsa.gov/recalls to confirm the work was done.
