I reported my vehicle is a whining noise coming from the engine. i took it in for a diagnosis. the technician informed me that no codes were detected; however believes it is the alternator. the car has 39k miles. as a previous owner of a 2011 infiniti, i believe this is a manufacture defect as i am the second owner and driven it for less than 6k. i initiated a claim with nalley consumer affairs to no avail; the representative stated that there is no listing of what is covered under warranty. claim # 28141832. i have requested that the regional manager contact me.
