13 months ago at 26,000 miles, I got a check engine light from the code P2196 O2 sensor 01 stuck rich. I called the dealer from whom I purchased the truck and the service manager said to bring it down and he would fit it in. When I got there, he was gone and the service advisor said that the diesel tech was booked up for the next three weeks and they couldn't do anything for me. He also said that I shouldn't drive the truck with that code but I could leave it at the dealership until the tech was free. When I told him that I had just driven 30 miles one way because the manager said to bring it down. He then told me "He shouldn't have told you that, he knows how busy the tech is, that's the breaks". I called another dealer in the adjacent town, and they said bring it over, we can get it today. When I got there, they took it in and two hours later they did the wire harness overlay, the connector work and a reprogram and I was on my way. Since then, I have never darkened the doorstep of the original dealer, and actually sent 6 sailors from the base where I work to the new dealer of which, 4 bought trucks and one bought a Challenger. Now, I got the P2196 code plus a P2BAC code. I called the new dealer who treated me really well and he told me that his tech has had a medical issue with his wife but if I wanted, he would give me an appointment for next week, which was today at 0830. When I got there, the advisor said that the tech's wife had passed away last Sunday and he is the only diesel tech. I told him how sorry I was to hear that about the tech, but after taking care of their employee, they should have called the customers that had appointments and cancelled them rather than have the customers come to the dealership for their appointments only to be turned away. This drive was 66 miles. While there, a fellow from Montana came into the dealership with a 2014 3500 that was missing badly. He left his 5'er and family at the campground and came in to the dealership and was told that they couldn't help him. We both left and in the parking lot called all of the Ram dealerships within 105 miles, and EVERY ONE OF THEM said that their techs were booked, some at least out two weeks and others out 5 weeks. We asked what the issues were and they said that there has been a run of diesel problems. So, here we were, one fellow from another state on vacation with his family and me, both with no help or any prospects. Can our trucks with the good ol' Cummins be this bad that the dealers will tell an out of town guy that he's on his own with a badly running $60,000 truck or a local guy with a check engine light? Now, don't get me wrong, I don't want head of the line privileges or anything, I would have waited for another appointment after the tech comes back, I truly understand but I should have been called about the tech's tragedy and certainly the poor guy from Montana who will most likely find an after market shop to fix his truck and probably trade it for a Ford, (God forbid). Sorry for the long post, but am I off base on this or are we in big trouble with this?
