Engine: “While driving on the Interstate check-engine light came on, engine governed to very slow speeds and ultimately became undrivable. This has happened twice. In May and August of 2026.

NHTSA complaint #11763795, filed 2026-09

Transmission and drivetrain: “We have had close to 30 failures of the Meritor Transfer Case in both International and Freightliner chassis. This case specifically and of which I will add photos, is a 2021 Freightliner. The internal coating is flaking off and clogging the oil pump pick up screen which in turn starves the pump and eventually leads to bearing failure. This is a safety concern because the T-Case is the central connecting point for the drive line. …”
