Fuel pump. The mechanics at the Mazda dealership brushed me off when I brought up the open recall on my vehicle. However, according to them it is a "preliminary recall," the mechanic said it wasn't an "open recall." This is my first vehicle and I stupidly put my trust into the mechanic and believed his words. I am not well-versed in vehicles but after extensive research, asking a friend, and referring to a VPC agent who deals with recalls on vehicles; it turns out there is no such thing as a preliminary recall outside of Mazda's definition. I told the mechanic it was an open recall and that I need to ship the vehicle to Hawaii and the shipping company can refuse service if there is an open recall. The mechanic still brushed me off and talked to me as if I was dumb because I couldn't understand what he was saying. …
