This reminds me of a similar story I had with our car (luckily not the Ram). I do ALL my own oil and fluid changes for exactly what others have said, I trust my work and care. The only time others touch my vehicles involves warranty work.
So we bring the car in due to broken heated seats, the module shorts and refuses to turn on when colder than EXACTLY -26deg. Go figure, too cold for heated seats...
The dealer is a 250mi drive from where we live, I drop it off, they fix the seats, and I drive the 250mi home. The next day I round up my oil change items and crawl under to get started. Well don't I find oil EVERYWHERE and a GIANT hole cut in the plastic skid plate under the oil filter. It's fresh and there's plastic shavings all over mixed in with the oil. I go to unscrew the oil filter and it's held on by maybe 3 full turns and when I first grabbed it was so loose it rattled around. Once off I can tell that whoever used the HOLE SAW to cut the hole in my skid plate went through the skid, up into the oil filter (still under power on the saw) it jammed the oil filter and UNSCREWED it and also scored my oil pan. I drove 250mi home on a deserted highway with an oil filter that barely hung on.
I called the dealer to ask W T F went on with my car because it just needed the SEATS fixed. He says there's a recall and some of the cars came without the access holes cut for the oil filters. I get it, it sucked having to drop the skid to change my oil, but they never asked me or even told me they did this. The shop manager apologized and asked me to bring the filter in as proof. Once he saw it a few weeks later he said the next work order I bring in would be discounted as an apology, I reminded him this is why I don't like other monkeys working on my stuff. I've never been back to that shop since.
Imagine the perfect storm for this screw up:
1) I do all my own oil changes.
2) They never told me they worked on the engine.
3) I drive home on a deserted highway and the oil filter falls off the car.
4) All the oil pukes out and my engine seizes up.
5) I bring it to the dealer and they tell me "well looks like you don't know how to change oil dummy, we aren't covering the engine".
I shudder at the thought of that. Long story short, don't trust shops.
