What happened is -the problems i have been experiencing which are mentioned above, have begun once again. Every time I go to dealer to get coolant added back into system after it overheats they are amazed time & time again like they don’t know what is happening. & maybe they are not educated enough on what is happening, so that’s fine but I need to tell Infiniti that & get refunded on parts I should not have paid for or at least try, either way I just want them to know. As of now I have taken my car to a local mechanic that only operates on imported vehicles, mainly he deals with Mercedes. I told him issues described in full & he simply said its clearly a head gasket leak, so he is going to take apart the engine from top, send the heads somewhere in Atlanta to see if their cracked/with any issues & replace the gasket. They have already began work. I will keep this post updated with hopefully Real good news in 2weeks time.
