    I traded in my 2006 6.0 litre gas for this new weapon. I love the new front end and all the power etc... (bla bla bla) . However if I can't go passed 7km per hour every time it gets cold, and this thing goes in limp mode and on a tow truck to the dealer, what good is this to me or anyone else. THIS UREA (DEF) SYSTEM SUCKS ! this is the 3rd time it is making a trip to the dealer do to the fact it is allergic to the cold. As I am aware the urea is around 65% water based, what kind of heated line is there? and don't think it's any good, I call on-star to run a diagnostics on it.....THEY HAVE NO CLUE.....I call several GM/Chev dealers.... THEY HAVE NO CLUE........Not sure what do to as we have a possible 3cm of snow on the way.... maybe a rocket launcher pointed at the PLASTIC UREA TANK THAT SITS 14 INCHES OFF THE GROUND ON THE PASSENGER SIDE.........this is a big problem...IMO and I don't feel there is much of a support team for this mess, and it is being kept on the down low....WHY ?

    I havnt had any problems with mine but I havnt used it much. From what I've read do not fill your tank untill needed to. The heater works a lot more effiecent when the tank is half full.

    Thanks for the advice Dave... I am in contact with a few dealers at this point ( need all the help I can get ) I ordered the truck from a dealer up north...and they are great , and now the truck is at a local dealer pulling out all the stops to get me rolling. I just want this unit to work, that is why I purchased new truck,plow and salter. I think the dealers that I have been dealing with can only go by protocol....but at this stage of the game they are telling me all they can do is install more software ! they are putting in program number 3.....and they said there is 9 in total. :confused:

    Are you getting messages that your exhaust fluid is low?

    That is the issue I've been having with mine... three times now. Message in the DIC tells me I'm low on fluid, when the tank is nearly full... add fluid, the message does not go away. Regardless of the DEF level, if the message does not reset, the truck goes into limp. My dealer just resets the message and I go on my way. I've never had it actually go into limp mode, but I have a friend whose truck did. The dealer promises me that it's a software thing, and that GM is working on a re-flash for the vehicle's computer. :rolleyes:

    Another interesting note, is that I had a jug of the fluid in the back of my truck and it was 4 degrees out, and the fluid was not frozen the least bit. I realize that because of your location, the temps you're dealing with are much more extreme than what we see here. My dealer did tell me the same thing that JD Dave said... only fill the tank part way. The heater is more efficient when there's less fluid to heat.

    It's beyond me why the level of the tank cannot be monitored at any time... kinda like a fuel gauge. It would make more sense to me, rather than a series of messages which send you scrambling to get fluid in the thing.

    Go to Dieselplace.com. and do a search on the subject. There's a bunch of reading there on the problems they're having with the system.

    Other than that, I still love the truck! Thumbs Up

    Although it is good to plug it in at night, the block heater is just that... nothing to do with the DEF system.

    I still love the tank for now...lol but when you got clippers and lake affect flurries hitting home in 6- 10 hrs and all you can do is vent on plowsite...I am certain that you can see why i would think of that rocket launcher I mentioned before. As far as plugging it in, no I don't have a problem she turns over with lots of cranking power, big alternators, I ordered this truck the way I wanted it, it was not just a stocked unit, Z71 silverado, leather, rear sliding window, Bose stereo system, I picked the 397 hp motor the list is endless......so as you can see, I had high expectations for this truck....at 82,000.00 for truck, western wide out and electric air-flow salter which is another topic of conversation, the dealer that did the install on the plow and salter is no longer in biz after i was told they got bought out !...Nice- as you can see my plan of avoiding headaches and down time of getting NEW equipment is not working to well at this time. :cool:

    Trust me... I understand where you're coming from. I've been frustrated and stressed out with the issues I've been having too. It's never a good time to have issues during the winter.

    Good luck and keep us posted.

    Thanks cubicinches, and your right, I asked the dealers about plugging it in, and they all say it has nothing to do with the DEF system, plugging it in just keeps the anti-feeze warm ! I wish it would keep the urea warm also...lol and to answer your other question, the display lights up like Las Vegas casinos telling me its low and it will self distruct soon etc...LMAO sorry I have to keep laughing about this to keep me focused, no time to get angry.. tymusic

    Well after a full day at the dealer they managed to reset the computer....WITH NO GUARANTEE IT WILL LAST TONIGHT ! I was told that a tech that works at GM out of Windsor (I think) was going to bring new software in the morning, to rectify this problem. I did mention that if this unit crashes down on me tonight.....I am done ! out of biz before I even get started....great :cry:

    That's probably a good thing for all of you , more likely to get a GM rep involved and more help . Good luck

    X2, buy another vin# matched PCM and download a good EFI live tow tune, use the EFI live to shut down the DPF too. Best thing to do is buy another exhaust and remove the stock. This will bring you fuel milage back up, no SES lights, and no limping. But if you have to take it to the dealer you have to put it back to stock.

    Mike, I am sorry to read about all your problems. You rely on that truck heavily. Buying a new truck and to still have a fear of breakdown/non performance is terrible. Good luck with the repair/fix and please keep us posted on what GM has to say about all this. I am very glad I did not order a new Duramax for 2011.

    Like I said in your other post, you idle the truck too much.We have 40 of them with dpf and egr and we only have problems with the guys that idle them.

    Also if gm did not take the egr tube out to clean it you will always have this problem until they take it out and clean it the right way.They also have the right not to cover this under warranty and after 6 or 7 times you will need to replace the egr tube $$$$.

    If you don't care about the warranty anymore cut off the dpf filter and chip it.
    we have done that to 4 trucks and they work just amazing now
