I had my vehicle checked for transmission fluid befor sending it to dealership pohanaka hundai Subaru. This vehicle sat for 3 days before it was looked at. I told them it was a transmission problem. They said there was no transmission fluid in vehicle. No fluid on ground. They said it was a line that was broke or had a hole in it. About a hour later I was told it was not the line but the radiator. Asked if there was any fluid on undercarriage could not answer. Nothing has been done yet to vehicle. This is the problem I have had with them. I would like to know how many transmissions have gone out on the 2000 hundai Sonata.
