    Anyone getting the low DEF message? I've got 1400 miles on mine and it came on yesterday so I added 1 gallon as that was the minimum it said to put in according to the manual. I thought it reset, but apparently not because plowing a lot today it came on and said 300 miles. By the time I got finished with the lot I was down to 190.

    How are you cold climate guys handling this issue?

    sounds a like a computer error code issue. go to back to your dealer they fix that for you free of charge

    The dealer just said I needed to "thaw" the truck out in the garage. It's going to a different dealer tomorrow the next town over. It's a known problem but wasn't sure how others were dealing with it.

    That's my point! I'm in SW Missouri. I missed the major part of our storm because a coolant line fitting was miss-molded from the factory. So far this truck has cost me nearly $30k in lost revenue.

    There's a new calibration in the works to fix this. You aren't the only one... The best thing you can do it NOT overfill the tank. The tank heater works better with less fluid in the tank also.

    Ford is having issues with their trucks freezing up too, apparently from what i was told theirs go into a limp mode too so they cannot be driven. Gotta love that Urea injection!!

    www.dieselplace.com has been discussing this issue at length. Great site if you own a Dmax.

    Hmm My LML gets around 16 driving around mixed and pretty close to 20 on the highway driving it fairly hard. The mileage is a big improvement over our LMM's.

    The issues with the system will get worked out. It's a new technology on a redisigned vehicle. There are always kinks to work out on a new model.

    he would like to see that. stoped atthe house today with 1811 miles on it. and fuel is 9.80 per gal from dash info so far.

    also said exaust brake only seems to work 1/2 the time if you can even feel it when it works.

    the bumper warning system to keep you from hitting stuff on the rear of the truck dont even work right.

    and it was over full on coolent when he picked it up from the lot and since then has peed out a few times. but hasnt had to add any.

    factory winter front cover tabs broke clean off when he went to install it the otherday. even had it in the house warmed up and took it right out and snap.

    and the rear bowtie emblem after 600 miles has gone to crap. moisture behind the clear amber and all discolored behind there.

    his old 06 was 2x better on mileage and not nearly the problems of the new truck.

    said thay charge me almost 60k for this 2011 pile hell with that for the quality so far.

    11 Duramax DEF issues

    I have a 2011 Silverado Duramax LTZ with a new Wide out on it and have issues with both. The truck is in the shop for the 4th time with the same issues everyone else is having but each time it goes in they say they have it figured out this time. This time the DIC said "Service Diesel Exhaust Fluid System" and "See Owners Manual Now". I was plowing when these alerts started so I took it back to the shop and got my back up plow. The next day the truck would not start so I had to have it towed to the Chevy garage. Road Side Assistance has some issues that need addressed as well. At the same time these alerts came on the Western Wide Out quit, the plow control module died. I don't think these two are related but i'm not sure. I have been running the same equipment for the past 20 years, it's old but well taken care. I wanted to have a trouble free year this year but that has not been the case!

    The Chevy garage has said that they have not had any returns with these trucks after they reflashed the computer. Am I the only one that has had this issue 4 times?
