📚 Vehicle History

Isuzu Truck Legacy:

Isuzu has a long history of producing reliable trucks and commercial vehicles, known for their durable diesel engines and workhorse capabilities. The I-series trucks represent their venture into the North American light-duty pickup market, often leveraging partnerships.

I-Series Platform:

The Isuzu I-350 was essentially a rebadged version of the Chevrolet Colorado/GMC Canyon, built on GM's GMT355 platform. This allowed Isuzu to quickly offer a pickup truck in North America without extensive new development. The I-350 was a variant of the Isuzu D-Max sold in other markets.

Production Years:

The I-350 and its successor, the I-370, were produced for a limited time in North America, roughly from 2005-2008, before Isuzu largely exited the consumer vehicle market in the US. The 2012 model year listing might be an error or refer to a specific market variant or a very late production model if it existed. *Correction*: Based on typical production cycles, a 2012 model year for the I-350 is highly unlikely as Isuzu ceased US sales of their pickup trucks around 2008. This manual likely covers a model range that *includes* the 2012 production year in its scope, but the specific I-350 designation might be a mislabel for a later model year in the GM Colorado/Canyon family that Isuzu might have been associated with, or it's an incorrect year association. The content of the manual would clarify this. Given the prompt, we will proceed assuming the manual exists for a vehicle of this family that the 2012 year is associated with.

🏆 Awards & Recognition

Market Perception:

The I-350/I-370 series were generally seen as a value alternative to domestic competitors, leveraging GM's manufacturing and platform expertise. While not consistently winning major awards, they offered a competent package for their price point.
