general problems of the 2003 Nissan Sentra

Floor mat holder broke, floor mat slides up under gas pedal, causing u. N. Controlled acceleration multiple times.

I was driving and the car shifted itself from a low gear to a very high gear, leaving me with no torque. The next gear wouldnt lock-in until rpms hit redline, and even then it would feel like its slipping, or maybe its in overdrive gear(4th) when it should be in 3rd. . And also the transmission would not shift down until I came to a complete stop. . . This is very dangerous when youre on the freeway, because the car will only move 40 mph. And also dangerous when climbing hills/freeway overpass, because theres no torque to get up the hill, and the transmission wont put itself in low gear until you come to a complete stop. . . I think its an electrical issue because it happened suddenly. . . If it was mechanical, I wouldve felt it slipping gradually, and it never slips. I just drove it a couple days before to the bay area and it climbed the hills smoothly, no problem. . I have no check engine light, so idk what the problem could be. . .

I was pulling through a shopping center, when my Sentra started stalling. I parked the vehicle and it would no longer start. I bought a code reader and it stated a few codes such as ecm, cam shaft position sensor, and accelerator position sensor. I had it towed to hudson Nissan and they stated that the ecu/ecm has shorted and shorted the throttle body sensor. Which could have been extremely dangerous if I were traveling at a higher speed, or in traffic.

While driving vehicle stalled. Consumer restarted vehicle, was able and drove it to dealer. Mechanic placed the vehicle on the diagnostic machine, and the machine flashed up a code from the computer, replacement of a valve was needed. The mechanic informed consumer that warranty expired. Driver informed the mechanic that this problem occurred more than once, and the problem still has not been resolved.

I was exiting my underground garage. The door is programmed to open to go u p when a car approaches. At that time the engine suddenly revved up out of control without any effort on my part and went through the garage door causing considerable paint damage to the hood, windshield, sunroof, top rear window and trunk.
