Diesel fuel injectors are covered under the GM powertrain warranty
A Chevrolet salesperson explained that if a part is continually lubricated, it is covered under the powertrain warranty. This is the case for diesel fuel injectors.
However, it is important to note that the powertrain warranty only applies to parts that are made by the powertrain. Additionally, the specific parts covered under a powertrain warranty may vary depending on the provider, as well as the car's make and model.
For example, the Chevy powertrain warranty covers fuel injectors, but there are reports that the GM powertrain warranty does not cover fuel injectors for certain models, such as the Camaro and the Chevrolet Silverado.
In the state of California and a few other states, diesel fuel injectors are covered under the emissions system warranty for seven years or 70,000 miles. This coverage is provided if the car is certified for sale in California and registered in California or one of the other eligible states.

The powertrain warranty specifically covers Chevrolet models from 2007 to 2011, including passenger cars, light-duty trucks, crossovers, and vans.
However, according to some sources, fuel injectors are not covered under the powertrain warranty. This has been a point of contention, with some arguing that fuel injectors are an essential component of the powertrain and should be covered. In response, others have suggested that fuel injectors are covered under the emissions warranty rather than the powertrain warranty.
In contrast, diesel fuel injectors are covered under the GM powertrain warranty. Additionally, if your vehicle is covered by the California emissions system warranty and registered in California or certain other states, diesel fuel injectors are covered for seven years or 70,000 miles.
It is worth noting that the Chevy powertrain warranty does cover fuel injectors, according to one source. This includes the Chevy models of 2007 to 2011. However, it is unclear whether this warranty extends to more recent models or other GM brands.

California emissions system warranty covers fuel injectors
The California Emissions Warranty is a separate warranty mandated by the state of California, which covers vehicles with California emissions equipment. This warranty is valid for seven years or 70,000 miles, whichever comes first, from when the vehicle is first put into service. It is applicable regardless of ownership and covers a wider range of parts than the federal warranty.
The California Emissions Warranty covers diesel fuel injectors for vehicles with California emissions stickers under the hood and registered in California or other states that follow California emissions standards. These states include Connecticut, Delaware, Maine, Maryland, Massachusetts, New Jersey, New York, Oregon, Pennsylvania, Rhode Island, Vermont, and Washington.
It is important to note that the California Emissions Warranty is not the same as the GM Powertrain Warranty, which does not cover fuel injectors. However, diesel fuel injectors may be covered under the GM Powertrain Warranty if they are continually lubricated, as some sources suggest that this is a criterion for coverage.
To clarify coverage under the California Emissions Warranty, refer to your vehicle's owner's manual or contact the CARB Helpline for assistance. Additionally, consult your dealer or vehicle manufacturer, as they can provide information on covered components and authorized repair facilities.
