Check your own car
Each of these 10 campaigns covers a range of production, not every Isuzu NRR ever built — two cars of the same year can differ by a single week at the plant. Whether yours is among them, and whether the free repair was already carried out, is answered only by the number on its windscreen: check this NRR by VIN.

| Enter the VIN above | Open campaigns for that exact vehicle, straight from NHTSA |
| Check the repair status | Whether the free fix has already been carried out on this car |

Frequently asked questions
How many recalls does the Isuzu NRR have?
10 NHTSA campaigns on record, covering 2016–2026. Not every campaign applies to every car — coverage is by production range, so check your VIN.
Is recall work free?
Yes. Safety recall repairs are free at any franchised dealer regardless of the car's age, mileage or how many owners it has had. That is a federal requirement, not a courtesy.
How do I know if my NRR still has an open recall?
Enter its VIN above. We show campaigns that apply to that exact vehicle and whether the repair has already been recorded as done.
Why did a defect take years to be recalled?
On this model the average gap between the car being built and the defect being admitted is 1 years, and the slowest campaign came 5 years later. Defects usually surface as they accumulate in the field: complaints pile up, an investigation opens, and only then is a campaign issued.
