Hello all. I got a 2016 2500 6.7 80300 miles. 300 miles out of " warranty " my def pump fails. Took it to the dealer of course its out of pocket. They did a list of recals no joke 2 pages long. They replaced alot of emissions related parts. Has anyone had any luck getting a " courtesy " warranty on emissions parts. Ive been back forth google, searching the forums etc etc. So much mixed information on whats covered, how long its covered. Ive also come the thinking that your dealer support factors in alot. I know there are alot of posts about these issues on here. Just didnt want to hijack someone and maybe get an answer from a guy thats been there. Does anyone know what actually fails in the pump ?? Im in the heavy equipment business and we have one brand of forklift that looses def pumps continually. Some machines have had 2 or 3 pumps installed and no one knows what components fail. Circut boards, sensors its like mums the word. Its odd you can rebuild pumps injectors failing gauge clusters ecms. But a 20 dollar Chinese made part. No sir 1000 bucks please.. But then why do they want the core ?? Feel like im getting the screw job. Sorry to vent just curious if anyone has had luck pushing warranty after the fact. Thanks in advance guys
