sounds like the DNCEverything you said is a sad reality and far too common among all brands and associated dealer service departments. My local Jeep dealership is so bad I can't say what I think of them here. My last interaction with them goes like this: called to complain about a TSB that they used the wrong part. I had all of the information at hand and I verified all of it to back accurate. Speaking to a service writer about it. Says hold on, comes back and starts lying about what the TSB requires for the repair. I laughed and asked them to read it again to me word for word then. They wouldn't do it. Asked to talk to the manager. Was put on hold, never got to speak to a manager and even left a message to call me. 3 weeks have passed and still no call back. No resolution for an issue I've been aware of since October of 2020. So yes they suck, no they do not know how to fix vehicles, no they do not really care about their customers, yes they lie and don't care if you catch them doing it. There are seemingly no repercussions for their failures, lack of skills, lack of customer service.
