Took my truck in to the stealer today to get the P0380 code fixed, I was under the impression that the Glow-plug system was covered under the emissions warranty. Am I correct?? If so can someone provide me with a copy of it or a link so I can prove it to the dealer??? TIA -Jeff

It is covered. I had a glow plug issue about a month ago. All I had to pay was the $100 dollar deductible. I believe it is listed in your owner's manual.

That means if the dealer submits the claim with one of those labor ops, it will go through the system as emissions warranty. See if he is willing to submit it that way and if it pays, reimburse your $100.

OK, here you go. Article 1.2, page 15 & 16 in the GM Policies and Procedures Manual under "Ignition System". That is the Emissions- Warranted Parts List. Have the Service Manager look it up or call Customer Relations and tell them where to find it.

This is the perfect info, thanks!!!! -Jeff

Depends on what exactly is wrong, would also fall under the diesel warranty, but anyway if it is covered here you go, highlighted in Red.

Federal emmissions.

The warranty manual isnt shown for the 2002 on SI (Service information) but 2003 is, so this is all out of 2003. Should all be the same though. Give the dealer this DOC number for SI 835389

1. Federal Emission Control Warranty

Both the Emission Defect Warranty and the Emission Performance Warranty described next begin on the date the vehicle is first delivered or put into use and continues as follows:
Light Duty Truck Equipped With Light Duty Gasoline Engine
2 years or 24,000 miles, and 8 years or 80,000 miles on the catalytic converter and vehicle (powertrain) control module, whichever comes first.​
Light Duty Truck Equipped With Heavy Duty Gasoline Engine
5 years or 50,000 miles, whichever comes first.​
Light Duty Truck Equipped With Heavy Duty Diesel Engine
5 years or 100,000 miles, whichever comes first.​

3. Emission Warranty Parts List

The parts that may affect your vehicle's emissions are on the following pages. These emission parts covered under emission warranties are as follows:
Federal coverage - refer to the "Federal Emission Control Warranty" previously in this section.
California coverage - refer to the "California Emission Control Warranty" previously in this section.​
Important: Certain parts may be covered beyond these warranties if shown with asterisk(s) as follows:

(*) 7 years/70,000 miles, whichever comes first, California emission coverage.
(**) 8 years/80,000 miles, whichever comes first, Federal emission coverage. (Also applies to California certified Light Duty and Medium Duty vehicles.)​
