2 Crankshaft Position Sensor problem

Failure Date: 04/04/2011

I've had the same problems that other Infiniti I-35s have experienced in regards to losing power, engine cutting off and lack of bracking. My car initially stalled while I was parked at a red light. After a few attempts to restart, it finally did. I made an appointment to see the dealer about this problem four days later. While driving to the dealer, my car engine lights all lit up and the car stalled and I had no braking ability. Fortunately, I was going only about 10 mph when this happened and was able to pull over to a lane without cars and applied my parking break to stop the car. After five minutes of attempting to restart, it finally did. I was only two miles from the dealer, so I slowly drove it there. They told me the problem was both crank sensors along with the crank shaft. I had them replaced at a cost of close to $1000. It seems to me that if there are so many complaints regarding this problem, it should be looked into as a safety recall issue. If I were going faster, I could have crashed into someone. One week before this happened, I was driving through mountain roads with many twists and turns. If this happened during that drive, I would probably be dead by now.
