DEF low in less than 2 weeks

yes, the fill spot on these truck is so stupid!!! I work at a mack/volvo dealer and we have a 330 gal tote bulk tank with a spout(gas pump nozzle), best way to fill it up (and cheapest for sure!!)  spilling the stuff on wires is the last thing you want to do period!  mack issued a bulletin on def and said if you spill it on a wire harness to replace the harness immediately as the def will seep into the harness and wires and seep through taking out several harnesses and/or modules.

Sounds like a perfect system, completely thought out,  what the hell have these companies done to the once rock solid dependability of diesels.

What the EPA is requiring them to do, but as cheeply as possible.

Don't blame GM, its the EPA.

 

Our standards are such that most EU diesel cars will not pass the particulate test.

 

My DEF tank lasts about 4000 miles.....

I do blame GM, who puts the parts on the truck? Not the EPA, they might mandate the use of this crap, but's it's GM that put a system on that isn't working in the long run. They charge how much more for this engine than the 6.0? And they can't put on a well thought out system that doesn't freak out and strand people on the side of the road?

For 8 grand extra per truck, you would think the engineers would have enough time and R & D to come up with something that brings the truck back to the original diesel engines super long term durability record, when 250K miles with nothing but oil and filters was normal, and trucks where slow. If taking back some of that stupendous power eliminates these petty break downs, then do it, right? I understand these emission laws suck, but that shouldn't mean the truck does also...

I think part of the problem now is that all the manufacturers are trying to one up each other to the point that they are not spending as much time with quality control and long term testing as they once did, in hopes of getting lucky with their designs and to meet the guidelines set forth that they say "we'll deal with the major issues later on as we get the trucks out in mass numbers"  or "We'll fix the issue with the next design"  something along those lines.  Welcome to the age where how much money you spend on your vehicle and your brand loyalty mean absolutely nothing to the manufacturers.  They could care less if you go to another brand because you are pissed off.
