Bought a loaded Colorado 2017 4X4 in October. Have only been able to put 7,000 miles on it as it seems on the eve of any planned long drive check engine goes on. Three times now, exhaust particulate sensor, reduced power. Disappointed because I gad a 2001 LB7 sierra 2500 that game me no problems until 250,000 miles and 13 years old (then the typical LB7 fuel problems crippled the truck.).

Thought I would get similar results with much better MPG with Canyon. Taking it back to the dealer yet again; per Michigan lemon law if it happens a 4th time it is their truck again, which is my preference. Hard to believe a brand new trck with a $45K sticker is less reliab le than by 2001 trade in.

Newer trucks have a ton of emissions on them and that is where the problem is at. Any new diesel is going to have emission related issues unfortunately.

Your trade was a 2001 and it did not have any where near the amount of emissions as a modern diesel. For this reason people either delete or stay with older diesels (90s to early 2000s).

My Truck is 2017 4x4 diesel with 18,000 miles and it died once and reduced power 3 times . I am afraid to drive my new truck ! The dealer said it would take a month to get the particular matter sensor not happy

Sorry, sounds similar. There may be a light at the end of the tunnel. They replaced the entire exhaust recirculation (?)
unit and all sensors and I have put 8,000 miles on truck with no issues. Love the MPG; have my fingers crossed.

Ihad a 2016 Canyon 2.8 at 46000 miles it had been in the shop 35 days. lemon law tagged by dealer provide a new truck. the old truck had fuel pump, fuel filters, two batteries, emc unit plus a few other smaller problem. when it ran it got great gas mileage, 29 mpg at 75mph repeatedly on trips.
