2011 GM Diesel Trucks~

There is no heating element on the DEF tanks snow?? That is a major oversight if they did not heat that tank.

Yeah there is,factory setting is 90 minutes,the setting can be over riden to continuous to keep the fluid from freezing while on the road,problem is/happens when you park the truck over night,once the fluid freezes solid the sensors read empty DEF tank or tells ya you have $200 miles (at 55mph) to add fluid.

 Are these guys all doing SCR because it gives better fuel economy compared to EGR? It just really seems to me that in order to do SCR you will have a lot more longterm costs compared to EGR. 

I'm REALLY surprised that they did not heat the tank. I remember talks about this when they were first looking at the new tier requirements and that was a big talking point, especially in our northern climate.

 i have a buddy that had his freeze up on him and took into local dealer and they told him that there was a service update to fix the issue and as far as i know he has not had the problem since. this was 2 weeks ago

Yeah,the fix is to drain the DEF tank and refill.does'nt fix anything unless he parks in a heated garage,I've got a dozen of these trucks on the road,all but two are parked out doors and have issues and the def fluide is expensive.

BTW,I am a dealer~

Ford has a heated tank, and does not have a problem.  I am sure GM has put in for a Government Grant to help them understand the problem, they will reorganize and have these trucks good to go in a few months.

GM obviously didn't know piss freezes.

You moron eyexer, did you not read snow's response??? They DO have heaters but the issue is when the vehicle is off.

exactly!  thanks for making my point.

My brother has one, parked outside, froze everything up solid. 60K POS.

Do the tank heaters work if the truck is plugged in @ night?

Big trucks (Semi's) have been running Urea (DPF) for a couple years already but they've all got tank heaters and most are never shut off in the winter.

How is Dodge getting away with no DPF? Still just running diesel into the re-gen chamber and taking the mileage hit?

This failure is probably do to the Chinese owned portion of the company.

pness,

Just curious here, but where did you get that Q. and A?  Some genius actually wrote "The freezing and unthawing..."?
 
Seems to me that whenever I want something "unthawed" I put it in a freezer and it gets really cold and hard as a brick.
