Hi guys I have an 2004 fx35
So car rans like a champion than happened a weird thing . It started with not recognizing the fob( my key was at home, i mean the physical key what comes from fob ), I called a towing and in 15 min guess what i could start the car . and it happened to me a few times. car doesent recognize fob or key . when i put the key and turn it clockwise nothing happened, no lights no any sound absolutely nothing like i don't have the battery. but when car recognize the fob car starts with no problems.
now the next weird thing , when the car recognize the key and i could run it can shutdouwn randomly, abrupt shutdouwn no sign of life , and car again cant recognize the keys. I cought the moment when car was running and went to infiniti dealethey said " sorry but we can't find any issues , bring the car when it can't recognize the keys"
