Hello Everybody, After being a loyal Toyo Taco driver since 1997, I finally got tired of waiting for a Toyota diesel and bought a colorado 4x4 crew duramax. After breaking it in for a thousand miles, I drove 2600 miles to pick up a 3000lb+ trailer. Impressions: love the truck, love the pulling power, internal comfort very good. Some things bug: no dash indicator for 2 vs 4wd mode, I find the interior space not nearly as usable as Taco, mainly in terms of drink holders which only accept a coke can size and the door slots which fit a match book or two. I also haven't figured out how to turn off things like radio or podcasts (other than from cell phone source) so they sometimes continue to play in the background after I have hit the stop button. Maybe somebody knows the trick on this. Got almost 30 mpg on way out for trailer and about 20 on way back. Right after I got back, the DEF warning came on although it blocked out all other info so I couldn't even tell what mile I was at and the engine light came on too. I added DEF and the light went off but the engine light still on so I am scheduled for service tomorrow. I'm bummed about that but we'll see what they find. I guess it's sounding like going low on DEF after 3,400 miles is normal but I am disappointed. When they sold me the truck they said it should last 1-2 oil changes. No way that's true unless my usage is excessive or there's something wrong with a sensor or something else and that's why engine light is on. Will update when I find out. Anyway, summary is I like truck and hope it will be reliable but the jury is out. I appreciate this site!
