Oh, like the so-called free 50 point inspection? Hahaha
As you can see I have very little faith in dealer techs actually doing everything they claim they are doing and doing things competently. I only use dealer service for warranty work, and outside of that I do the work or take it to my local trusted mechanic.
Depends on the dealer though. There are some good ones and some bad ones out there. Hyundai is known for having dealerships that cover the entire spectrum from horrible to good, because they don't seem to enforce a better dealership experience in general.
I'm lucky that mine is actually good. I've always been taken care of by the service department. In cases where I was unhappy with them, I was always able to talk it through and get it resolved. They always send a survey after every service appointment, and I can leave a public review as well. In the one case where I thought they should have done better, they contacted me after I filled out the survey.
I own a 2012 Sonata as well as the Palisade, which has the infamous Theta II engine. I'm on my second engine, and I've had all sorts of other issues with that car. Plus, I drive a lot, so I get it serviced often. At the end of the day, I'm still driving it with 175k miles on it and everything still works.
I've used local mechanics here and there over the years as well, for various cars, and I've never had a good experience. And to be completely fair, I've also experienced bad dealerships from other brands.
Bottom line, local mechanics and dealerships can both turn into bad experiences. There are good ones and bad ones on both sides. Rely on experience and word of mouth from others to find the good ones. If you have a place that you trust, whether local mechanic or dealership, stick with it.
