I was a service adviser at a nissan dealer. I could get a warranty claim denied if you looked at me wrong if I felt like it. You could give me all the maintenance records you wanted and it didn't matter. One call to the rep and say something is fishy... denied... Not saying i did it much but one guy tried to drag me out back to try and kick my ass... besides my tech grabbing a big ass crow bar. he no longer has a warranty on his car at any nissan dealership. I could also get your car or truck repaired when your out of warranty if I felt like it. I repaired cars under warranty that were sunk in water and the engine was full of water just because the people were cool with me and didnt give me crap. If a person made my job hard it was even harder on them. So word of advice be cool with the dealership and you will get taken care of most of the time. If your not being taken care of. dont ***** or complain. just go to a different dealership and be NICE to them.
