I have followed this thread for awhile. Too me, it is something Dodge needs to get their hands around. I have talked to a couple local dealers, one was voiding warranties for contaminants, as well as water. The other was more concerned with water. The dealer concerned with water specifically mentioned a truck that had been started 212 times with the water in fuel light and/or the check engine light illuminated.
In my opinion, the filter should "catch" the contaminants. If it loads up, the truck should shut down, or go into a "limp" mode. (Assuming we need to lube the new pump) Everyone who drives a diesel gets bad fuel, period. It is just a matter of when. If DC voids warranties for contaminants in fuel, they have voided warranties on all our trucks, and are just waiting to tell us.
Water would be a different story, a better filter will just give us cleaner water. If a light comes on the dash, than shut your truck down. If you don't, and the dealer can tell with a scan tool, it is reasonable for there to be some non-warranty discussion.
The fact that some of the contaminant is coming from their defective tank, and that the quality of factory filtering is possibly no good just compounds the horrible PR position they are putting themselves into.
I switched from Chevy to Dodge in 1995 because I thought their truck was better than what we had in the Chev. It cost me $5000 more to buy the Dodge, but it did the job, and spent much less time in the shop. (Really, very, very little time. ) The cheapest tool usually isn't the best VALUE and I learned that lesson the hard way with a 1995 Chevy diesel.
But that was then. Now, Dodge REQUIRES a dealer visit if one of the hundreds of trailers we handle has a bad turn signal, and trips an "internal" breaker? They have gone to a cheaper 6 speed transmission. The axles, to me, are an unknown quality. Even the formerly best in class engine is maybe not? Or maybe the advantage is much less.
Another drawback to Dodge has always been dealer service. Not the quality, but the typically unavailable parts, and ensuing repair delay. (If a dealer has a 5 million dollar inventory in trucks, but not the $100,000 in repair parts for that truck, what is that?) Admittedly, they may be comparable to Ford/Chev. But before, they would repair the vehicle, it just took a long time. Now they seem aggressive on whether it is even a covered failure?
I wonder if the fuel deal is the last straw for some customers? Or maybe something else?
I expect we have more bad news coming though. Transmission choice, for the OEM, is probably a difficult question of cost and benefit. BUT, if DC isn't smart enough to give us fuses for trailer lights, they are probably so out of touch IN GENERAL that we have absolutely no hope.
