INTERNATIONAL issued a recall on the 4300 and 4400 models

Certain heavy-duty trucks. These vehicles could experience a loss of the low beam headlights, the high beam headlights, or both. A software problem within the electrical system controller (esc) can cause the circuit for the low beam or the circuit for the high beam headlights to fuse or open, resulting in loss of either the low or high beam headlights or possibly even both. A headlight fusing condition could occur without warning to the driver and potentially leave the driver in a blackout situation while operating the vehicle in the dark. Correction: dealers will reprogram the esc.
