The DEF heater/tank shorted out. The DEF system has thrown a code 3 times in the little over a year I-€™ve owned the truck. This final time I was told that the tank needs to be replaced. The truck has now been in the shop for 2 months and there is still no ship date on the replacement tank. The tanks are on a national back order. From what I understand there are about 9,000 people waiting for this DEF tank countrywide. I now have a $60k work truck that I am paying for but cannot use with no reasonable end in sight.

After owning the brand new truck for less than 24 hours (approximately 170 miles on the odometer of the vehicle), I was driving in a straight line on a 2 lane highway at approx. 50-55mph. My foot was lightly on the accelerator, maintaining speed, as I had just passed through a traffic circle about a mile prior, and was in a small line of "traffic" travelling on the road. The rear wheels began to lightly shake (it felt similar to driving on rumble strips) for approximately 3-5 seconds, then several warning lights on the dash lit up and the truck violently "jerked" then pulled and drifted onto the right side of the road, onto the shoulder. The truck then sputtered and stalled. I did not attempt to restart or move the vehicle, instead worked with the dealership to obtain a tow truck.
