I went to my dealer today cuz my engine light came on. I have a 2002 Hyundai Accent with 35K on it. So the guy came out from his desk with a small device and plugged underneath the steer. I asked him what he was doing and he said he is trying to understand if the engine light came on because I did not do the 30K tune up (he asked me that before) or is it something else. Anyway the device said something that he said it can be anything. So my car is the repair shop and I am waiting in the room, all of a sudden I saw this big poster on the wall with charges and how to keep the 100K warranty etc etc There it said, we need to get a transmission flush service every 30K miles and if we don't and something happens to trasnmission before 100K they will not fix it. So I went to the guy and asked him how much they are charging for a quart of Haundai brand transmission fluid. He said it is 8 bucks a quart and that I need 9 quarts to flush it thoroughly. (72 bucks) He said they are charging 140 bucks and if I go somewhere else they have to call Hyundai Dealer to purchase Haundai Brand Transmission fluid anyway. Because Hyundai requires their brand to be used. And I paid 140 bucks. He also said spark plugs are not platinum in Accents they are regular. Was this guy lying?
