Source: NHTSA, updated daily. Last checked 2026-10-18. Recalls apply to specific VINs — run your VIN to confirm.
4 safety recalls, most serious first
1. Fuel system
What's wrong, in plain English: Fuel lines, tank or pump. Fuel problems usually mean a leak, and leaks mean fire risk. The affected vehicles have a fuel tank that may corrode and leak fuel.
What could happen: A fuel leak in the presence of an ignition source increases the risk of a fire.
The fix: Isuzu will notify owners, and dealers will replace the fuel tank, free of charge. Isuzu issued an interim notification to owners on December 18, 2015. The recall began on April 8, 2016. Owners may contact Isuzu customer service at 1-866-441-9638.
What to do
- Check whether your car is affected: enter your 17-digit VIN at nhtsa.gov/recalls. A recall covers specific VINs, not every 2007 W4500.
- Book a repair at any authorized GMC dealer. Quote NHTSA campaign 15V704000.
- The repair is free. By US law, safety recall repairs cost the owner nothing, no matter the car's age or mileage.
- Manufacturer hotline: 1-866-441-9638.
- Buying this car used? Ask the seller for proof the recall was completed, or run the VIN yourself before paying.
