Verdict · NHTSA data
Limited data — recalls on file
NHTSA has just one complaint on file for the 2001 Kenworth W900 — too few to judge reliability from owner reports alone — but 9 recall campaigns apply to this year, so any used example should have its VIN checked for completed recall work.

“CONSUMER STATED THE FUEL TANK BRACKET IS NOT STRONG ENOUGH TO KEEP TANK FROM TWISTING, THE STRAPS APPARENTLY ARE TOO BIG AND LOOSEN FROM WEAR, CAUSING FUEL TANK TO TWIST AND LEAK TO FUEL, DEALER AND MANUFACTURER WERE NOTIFIED.*AK *YH”
The record is thin — 1 NHTSA complaint — so owner-report data can't strongly confirm reliability either way, though 9 recalls should be verified as completed.
