2003 Nissan 350Z Owner Comments

problem #5

350Z 6-cyl

  • 64,000 miles


While driving on the freeway my car died out and tcs slip lights came on. There was a loss of power and I had to pull over to the side. While doing so I almost got into an accident because several cars almost hit me and the area that I had to pull over had a very small median. I restarted the car and every thing was fine. The next week the car died out many times while going up a hill on the way to the Nissan service dealer. They changed 2 cam position sensors, and 1 crankshaft sensor.

The contact owns a 2003 Nissan 350Z. The failure occurred in 2005 while driving 75 mph the vehicle shut off without any warning. The vehicle restarted on its own in 3 to 5 seconds. The failure recurred 4 times during an 18 hour drive. The Nissan dealer was unable to duplicate the failure. Three days after the vehicle was diagnosed, the failure recurred. The dealer later stated that the heat may have caused the vehicle to shut off. While adding fuel to the vehicle and attempting to start the vehicle, it lost all power and the contact was unable to restart it. The contact opened the hood to observed that there were no wires disconnected and was able to restart the vehicle. The contact is aware of the risk and stated that the electrical system may have caused the failure. In December 2007 the dealer confirmed that NHTSA campaign id number: 03V455000 component: Engine and engine cooling, was not related to his VIN. The failure mileage was 2000 and current mileage was 35400.

2003 Nissan 350Z original owner. While driving around 40 mph, engine stalled, twice in 2 hours, check engine light came on. Coasted to side of road, waited for maybe 15 minutes and engine restarted both times. I took the car to the dealership, left it with the service manager who drove it home that night to try & recreate the problem. Was told if they could not recreate the problem there was nothing they could do. They could not recreate the problem. About a year later a recall was placed for the engine sensors but my VIN number was not on the list, so no replacement. It has never happened since then. There was less than 20 thousand miles on the car at that time.
