It only took five complaints to the National Highway Traffic Safety Administration (NHTSA) for the agency to open up an investigation into transmission problems in the 2013 Infiniti JX and Nissan Pathfinder. OK, five complaints and a ton of early warning data submitted to Nissan.
Owners complain their vehicles lose all power when the transmission fluid leaks out because the cooler line connection fails. Only five owners have complained about the problem, but NHTSA also spotted the problem in early warning reporting data submitted by Nissan.
Turns out transmissions work better when the transmission fluid doesn't leak all over the ground, who knew? Well, Nissan for starters: More information on carcomplaints.com
Nissan [and Infiniti] knows there is an issue because they issued a dealer service bulletin in July of 2013.
