Radiator fluid spuing all over the ground running hot but did not show overheating temp on dash never showed no over heating temp on gauges or nothing. Motor cranked up days later and was knocking due to knocking. Did not know it had a recall bought it the same year it broke down ran good until then but took over a year to get it tore apart and someone to rebuild the crankshaft because it casused the motor to knock and it caused it to mess it up and need a rebuild the motor and I bought parts and all and cost a good bit for someone to rebuild it for me CASUE I know nothing. Of motors. Or cars parts just basics.

My car for the last year will drive 5-7 miles and stall in regular traffic. We replaced the fuel pump. I finally have enough $ to take to nissan. They came back with it needs all 2 cam shaft sensors and crank shaft sensor replaced. When I go on line and search my 2003 350z touring edition recall, there was a recall for this problem as it appears the wires can break inside due to temp on solder joints. I would like to know if this is this a problem that was noted on a recall and this is an ongoing problem with this same model, why now am I going to pay nissan $1200 for the repair that should be covered. I need this investigated

My 2003 nissan 350z was exhibiting the exact symptoms of a nhsta recall number 03v455000 ( nissan number r2202) recall. I contacted nissan dealers and nissan consumer affairs with my VIN and was told it didn't fall under the recall. I then took my vehicle to the nissan dealer service department to have it diagnosed and the dealer concluded that both (2) cam position sensors and the crank position sensor, were failing and needed to be replaced at a cost to me of 378.86 which I paid and have had the vehicle back only a few days (<100 miles) but so far seems to have resolved the issue. I again contacted nissan consumer affairs and was told there was nothing they would do. I further explained my belief that the recall was more widespread than initially thought by nhsta and nissan to no avail. I have spent 20-30 hours doing online research as to what would cause the issue and it all seems to lead back to the recall symptoms. I further realized that many other people experienced the same issue but can't speak as to their specific solution and therefore thought it prudent to try and bring it to the federal safety agency for further study and database information. I would very much appreciate the federal safety agency assistance in this matter to have the money I spent reimbursed to me by nissan consumer affairs as I believe this repair should have been under the recall. Thank you for your consideration in this matter.

My wife was driving the 350z on the highway and slowing down with traffic ahead. The engine stalled all of a sudden. The cars behind could have smashed into her and kill her. Luckily that did not happen. I searched the internet, it looked like there were many cases of 350zs stalling. Internet told me that it was caused by faulty camshaft position sensor, which was exactly what nissan dealer in dublin california replaced. In fact they replaced both camshaft position sensors. Check engine light did not come on when the vehicle stalled as indicated by the dealer. The engine would not start despite many tries. After 10-15 minutes or so, the engine started and the check engine light came on. Some of the 350z was recalled. However dealer indicated that my VIN number is not on the list. I feel the nissan should pay for my $674.44 repair bill as it is very dangerous for a vehicle stalling while driving.

Car abruptly without warning dropped speed by 15 MPH with the engine service light and the slip light and the etc light coming on. Almost killed by the truck behind me; he swerved to the emergency lane to avoid hitting me due to the sudden deacceleration of my vehicle. Recall r2033/r3022 describes situation. There is a campaign 03v455000 but nissan will not honor this for my particular VIN.
