The crankshaft angle sensor or the camshaft position sensor can fail and cause loss of engine power, an engine that cuts out, and other drivability problems. This will cause the Check Engine Light to illuminate. Certain models have been involved in a recall to replace the camshaft and crankshaft sensors.

    Engine turned over and started but took longer than normal.
    After sitting for 9 hours, engine turned over and won't start. Tried 3 or 4 times. Then pumped the gas while it was cranking and it started (might be a coincidence). That evening, turned it off and it would not start at all. Had it towed in to Infiniti and they said it was the crank shaft positioning sensor. Replaced and all has been well since.

    all VSC lights went on and skid light....service engine soon light went on. Ran computer and found camshaft position sensor failure, cylinder bank 1. Replaced it but the issue persists. Engine RPMs jump up and down, car sputters then cuts all power. happened a few times. this is definitely unsafe. Going to call the dealership this weekend. Just started maybe 5k ago.

    I first experienced the issue when i was leaving a gas station. I went to crank the car as usual, did crank but took longer than in the past. Soon after check engine light came on. I went to check on the what caused it and the diagnosis came back cam sensor. The next day i was driving back to work from home, the rpm went up and down, then eventually lost all power. The car would not turn on; I waited for a few minutes, the car crank up. Drove a few miles and repeated and cut off. I eventually got it to the repair shop. Changed both sensors. Now waiting to see if the problem continues.

    Car loses power while driving. Also will not start on a regular basis. Engine light comes on, throws the code for cam sensor. Replaced 3 times, improves for 1-2 days
