My parent’s 2009 infiniti FX35 was towed back home after it left him stranded on the side of the road. The car would stall for a few seconds and then drive. He would then press on the gas and it would just revv without doing much, and then come to a stop. I went to check it out and found not engine codes. The car would just reverse when put in DRIVE, R, and N. I have never seen anyone complain of that issue on infinitis. I do own a M45 and work on it myself so I am very familiar with working on these cars. Can anyone point me to a possible solution?
