Isuzu Manufacturing Services of America, Inc. (Isuzu) is recalling certain model year 2001-2013 Isuzu N-Series; model year 2001-2010 Chevrolet and GMC W-Series; model year 2001-2004 Isuzu FRR and model year 2001-2004 Chevrolet and GMC WT5500 trucks. The affected vehicles are equipped with an optional oil pan heater (RPO code IG3). Debris may collect at the contact point of the heater plug and the extension cord. This may cause overheating of the extension cord.
Consequence: Overheating of the extension cord could melt the oil pan heater plug and/or block heater plug, resulting in an increased risk of fire.
Remedy: Isuzu will notify owners and dealers will inspect the trucks. The extension cord and damaged components will be replaced, free of charge. The recall began on August 30, 2013. Owners may contact Isuzu at 1-866-441-9638.
Inspect model-year patterns, reported mileage, monthly activity and the evidence behind each signal.

2004 GMC 2500HD HAD VEHICLE IN FOR SERVICE IN 2009. GARAGE STATED THAT ALL BREAK LINES WERE EITHER RUSTED THROUGH OR WOULD SHORTLY AND NEEDED TO BE REPLACED. I DID NOT BELIEVE A VEHICLE WITH UNDER 25K MILES COULD HAVE SUCH AN ISSUE SO THE GARAGE PROVIDED PHOTOS TO SHOW THE EXTENT OF THE RUST AND THE LEAKING LINES. I HAVE SINCE SEEN THAT THE NTSB IS INVESTIGATING GMC TRUCKS UP TO 2003 BUT IT IS CLEAR THAT THE PROBLEM IS ALSO PRESENT ON 2004 MODELS. REPAIRS WERE ~$2900. *TR

Emerging complaint spikes
Complete months in the latest six months with at least 10 complaints, at least twice the preceding 12-month average, and at least three square-root deviations above that average.
This is a descriptive screening rule, not a statistical defect finding. Publicity and reporting changes can increase submissions.
No complete months meet the spike thresholds for this selection.
Equal-age model-year comparison
Model-wide cumulative reports during the first three or five calendar years, starting with the model year (age 0). Only fully elapsed windows are compared.
