Verified

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.

    This happened twice, both while on the freeway immediately after acceleration at a high speed, 5th gear. It stalled. The first time, I lost power - NO electrical lights came on, I could just feel it. as I pulled over, it just started up again, and moved - thought I imagined it.
    Second time, one week later - SAME freeway (odd). It stalled, lost power, after about 1 minute as I was moving toward the shoulder The check engine light came on first, then all usual STALL lights and finally SLIP. The SLIP light I had never seen prior to this occurrence. Immediately researched, seems it is a recall item - I wasn't aware of. I bought the car in 2013, with 135K miles. Have had no problems with it, except one - Radiator went due to a leak in the Power steering fluid- long story but after a "check up" seems the mechanic didn't tighten the cap, lost fluid/then hydrolics - then it overheated and blew it's LID! (a Steamy mess, good thing my sunroof was closed, I could have been burned)

    Same issue. Local mechanic told me to go to dealer to get the entire ECU replaced.
