This filing is one of 26 Isuzu notifications from 2022 in this archive. For scale, 610 of the 4,890 filings in this archive report a larger number of affected vehicles; the vehicles involved here were manufactured over a span of about 6 years and 3 months.
Defect
On heavy-duty trucks, the key-ON relay and ECM relay lack sufficient durability. The plastic bobbin inside each relay shrinks due to heat, creating a gap between the bobbin and the coil. Continued operation allows driving vibration to break the coil wire, causing an engine stall.
Corrective action
On all vehicles, replace the affected relays with corrected parts.
