Car Accelerates On Its Own problems of the 2002 Nissan Pathfinder

With the automatic transmission in reverse and my foot on the brake, the vehicle suddenly accelerated to around 6000 rpm while backing into a parking space. I came within a foot of the bumper of the vehice parked in the space behind the one that I was parking in. I had to turn the ignition switch off to stop the vehicle as the brakes would not stop it. I re-started the vehicle in "park" and the engine was still racing at about 4500 rpm. I turned the ignition off again and re-started the vehicle and this time the engine idled normally. I took the vehicle to the Nissan dealer in toms river, NJ on July 2, 2003 and explained what had happened along with the fact that the "service engine soon" light was on. The dealer was unable to find a problem and stated on the repair form "tech test drove vehicle and also checked to stored failure codes. No codes detected, unable to duplicate sudden acceleration issue". When I picked the vehicle up, they told me that the vehicle was fine and safe to drive. I also contacted Nissan consumer affairs on the day of the incident and after picking up the vehicle from the dealer. On both occasions, Nissan stated that they were not aware of any sudden acceleration problem with the 2002 Pathfinder and that there was nothing else that they could do if the dealer was unable to diagnose and repair the problem. I made both Nissan and the dealer aware of the fact that there were two (2) complaints of this type on your web site for the 2002 Pathfinder and I even gave the dealer a copy of the complaints that I printed from your site. I also see on your site that there are five (5) complaints of sudden acceleration for the 2001 Pathfinder and three (3) complaints for the 2000 model year. I hope that your agency will investigate my complaint, as Nissan and the dealer both state that there is no problem of sudden acceleration with the Nissan Pathfinder.
