engine derate in 85 miles due to def code

Ram diesels will shut you down in the middle of nowhere and dash will say you have 85 miles to go before truck computer will derate you to 5mph. You have to get to a dealer before then or else you will be going 5mph on a freeway and getting someone to run into you causing death. Dealer resets your computer at a cost of $200 and says " good luck". This computer derate is ordered by the EPA if system senses error in the def system. This is the most stupid rule that is going to kill many folks. So what if the def system not working 100%? A bit of more smoke? At the risk of being shut down in the middle of the desert and being stranded? Do your homework before buying a diesel truck! All diesels have this problem, even semi trucks! Send your congressman letter complaining about this EPA rule.
