When something goes wrong, it can distract us or keep us from learning. What happened to you is proof there was a reason for you to check, you just didn't know it at the time. There is a huge difference between shouldn't have to and shouldn't. So when this issue is all water under the bridge, remember there is a reason you SHOULD check the oil in those circumstances. That keeps it from happening again.
Sounds like you were burning oil and it was never checked. If the oil was changed ever 5k, and assuming they DID change it as 10-12K thats almost 1qt per 1k miles. Thats a lot, and they should have noticed it at the first change that it was multiple qts low.
I make enough to buy a car that I like and I chose this platform I loved the car but the service is lacking. Honda and Toyota are great brands nothing wrong with them type r will drive circles around a GT PP on the track but I liked the sound of the coyote. As for where I’ll take my business next I will be getting a AMG Mercedes.
