I will when mine comes in since it's a new model. The duramax is proven over in Asia but since Uncle Sam and the EPA got their hands on it I want to be covered as long as I can in case something goes wrong.
That is one of my concerns. This being a "new" engine, who knows what sort of watering down they had to do to meet California regs.

I'm curious if anyone purchased an extended warranty for the Colorado Diesel?
I purchased an 84 month/75,000 mile warranty thru Century Automotive Service when I purchased the truck at the GM dealership with $100 disappearing deductible and got the WRAP PLUS Comprehensive - best plan for $2095. Also bought the 5 year/75,000 miles maintenance program for $620 as I wasn't sure what service/oil changes/DEF/etc costs would be for diesel engine/turbo/4WD/transfer case. Cost me about $37 a month more for both and peace of mind. Glad I did it. I work/travel 60 hours plus a week and don't have time for servicing at home or worrying about this great truck. I don't need any opinions on whether it was a good deal or bad. Just sharing info.

Hi,

I just purchased a certified used 2017 Colorado Diesel, it has 12/12,000 mile thru GM. I can get an extended $0 deductible thru Zurich. After driving the Colorado for a little bit the dead pedal and transmission shift points are my only real gripe. Truck rides great and the mileage is fantastic. I tow a race trailer about 58 miles each way. I was thinking of getting the extended warranty since I’ll be towing and my worry is really the transmission as I know some of have trouble with it. I naturally also want to tune it to get the transmission to shift correctly and have a little more torque.

I know if you put a tune on it and you have something catastrophic GM will probably tell the dealer to pull the logs. I’m wondering if you have a third party warranty like thru Zurich if they will instruct GM to pull the logs and possibly void the warranty? I’d think once you are out of GM warranty and GM is not paying for it that they don’t personally care too much if you put a tune on it so a bad failure might get covered by Zurich. Any thoughts on this? If I have to wait a year to put a tune in it I can but I know eventually it’ll drive me nuts not having the power I know the truck should have.

Read the warranty weasel words carefully and you will find that that deviating in any way from the OEM build and not performing OEM scheduled maintenance will result in the excuse to not cover anything :(

My son had a Dodge Dakota with a K&N air filter and 2" body lift pucks and the third party warranty would not cover any engine or suspension/drive line related items.

I have one, can't recall much about it as it's late at night and I'm forgetful.
