You know it always seems that the tech who's handling my ride knows far less than I do and I'm not a tech. I guess there is a lot of people out there that "just need a job" and they happen to be the next tech in line when I'm next in line. Damn! Anyway the older I get the more prone I am to speak out. And I was always eager to speak out! I will stop what is going on and ask for the manager. I will have only the best tech in the shop work on my ride (not happening). It's kinda like if you go to the burger joint and complain, you can expect to get spit on your burger! Anyway LOL. I owned a 1973 Vega GT in 1973 and when it smoked like Hell and used oil like crazy and overheated and died on me, they said it was my fault because I painted the cylinder head. Go figure. Anyway they wound up putting a new motor in with steel sleeves. Imagine that. They said it would never run right afterwards but the pipes chalked out and I never had another problem with it. What I see is that some dealerships just seem to ward off all small complaints as much as possible in order to lower their cost of operations. You know what they say, "The squeaky wheel gets the grease". So, if you don't get the results you want, just complain a little louder and louder still. Eventually you will get what you need. Go straight to the service manager. If you don't get what you want, call the number in the owner's manual. You might be surprised how fast they fix it, and how nice and eager they will be to help you in the future.
