GMC Canyon with 2.8L Diesel

The EPA is a government entity. I wouldn’t trust them.

Bumping this tread. I am in the market for a new truck. Going smaller. Currently have a 2500 Silverado 6.0. Colorado ZR2 diesel is in mind. It has been a year since everyone talked about this. Still loving? Any issues?

My Silverado NBS 2500HD is killing batteries. Some auto forums say this is the radio drawing power while the truck is turned off. I have pulled the fuse that powers the radio/onstar to charge the battery. I am at the point I will never buy another GM product again. They are badly designed. Dealer wants $95 to guess what it is. Last year another GM product I own left me stranded, $35 part cost me $400 at dealership.

Garbage Machine=GM

I have a buddy that has one. He has issues with it sucking rain into the air intake and throwing engine codes on a regular basis. Not a big deal around here, but he is on the road all the time and it is very frustrating for him, and they have no way to fix it at this time.

Well the radio fuse is drawing 1 amp every 15 seconds or so. The radio is tied to the onStar system and uses the speakers. I called OnStar and they claim they only query the system once a month for the maintenance check. Last time I had a problem with OnStar they billed my card, but they didn't credit me the phone minutes. When I call to complain, I always get a rep from some foreign country. I can't even understand what they are saying. effing disaster on 4 wheels. As soon as the wind stops, I will check the current draw on the OnStar.

Well I bit the bullet and bought a 2018 ZR2 with the diesel. It is the most un-used, used vehicle I have ever bought. It only has 2700 miles. Very Happy someone else took the off the lot hit.

The 2018 ZR2 I saw today was MSRP of $49K. The dealer is going to reprogram my radio under a TSB, hopefully for free. If that doesn't fix it, then I have a buy a new radio. I am just wondering if the truck was hacked through OnStar. It just started this last year.

Seems like the dealer fixed the problem by reprogramming the "body control module" (BCM). I came up with the diagnosis myself. Cost was $115. How did the BCM programming become faulty? I have no idea! I am speculating that somebody hacked it through the OnStar...

Well the TSB (technical service bulletin) came out in 2009. I bought the truck new from the dealer in 2007. They made me pay for something they should have fixed in 2009. So no more GM products for me, and no more purchases from the dealer. eff GM & the Spradley dealership in Pueblo!

What kind of towing can the 4 cylinder diesels handle? I assume that the rest of the suspension components on the truck are still Colorado sized.
