While driving at around 40mph, my 2005 Nissan 350z (41xxx miles) shut down completely. No power, brakes, steering, anything. I glided to a stop and pulled over as best as I could. Every indicator light came check engine, service soon, tire pressure, etc. I was on a flat, busy city street going straight when this happened. Prior to this, I had no indication of a potential problem. No check engine light, etc. I called aaa and after about 20 minutes, decided to see if it would start so I could move to a safer place. It started right up. I've since been able to start and drive but this was extremely dangerous. Had this happened on the freeway, it could have been a catastrophe for me and the drivers around me. It's a very concerning safety issue. I've read it is ongoing with Nissans the same age as mine. Some were recalled and repaired but I looked up my VIN and it's not covered. Taking it to a dealer tomorrow but appreciate any help reporting and resolving this issue. Thanks.
Engine quite on highway, causing loss of power steering and power brakes, nearly causing a crash on a dangerous mountain road (highway 17 in California). The check engine light came on and stayed on. The dealer, santa cruz Nissan Dodge (state reg. # aj-35673-n) traced the problem to a faulty crank position sensor which was replaced on 4/3/06 (repair order no. 157547). A problem with failed crankshaft position sensors caused a recall for 2003 350z with VIN's in the range jn1az*4* 000001-100167. The engine problem recurred two days later on 4/5/06 at an odometer mileage of 8,513, again causing the loss of power steering and power breaks, again nearly leading to a crash on a freeway. This time the problem was described as engine code po420, po430 -low catalyst efficiency. The dealer replaced the catalytic converter (repair order no. 157686). Since then I have had four additional engine failures during freeway driving with similar symptoms but the check engine light did not stay on and there was no code indicating a failure when I took the car into the dealer at 12,679 miles on 11/22/06. The dealer did not service the car at this time (repair order no. 165910).
