Rear Suspension Shock Absorber problems of the 2003 Nissan Altima

I am very unhappy with my 2003 Nissan Altima. I purchased it used in Aug. 2002. It has been in the shop numerous times for several things. Faulty shocks, which took three visits and two different shops to get it fixed. And the latest problem, not starting. And to top it off on christmas eve stalling in the middle of an intersection. Baa hum bug, no one wanted to help, they just wanted to honk, like I chose to "park" in the middle of a turn, in the intersection. After reading all the complaints on this website I am uncertain that they fixed the correct thing. They replaced the starer coil. But when I went to pick up my car the service engine light was still on. So next they replaced a sensor that is a new recall campaign. I purchased my car with exsisting recalls that I was never notified about. The only reason I found out was because I call to complain to the factory about the treatment I got from north bay Nissan in petaluma, CA. And the lady I spoke with informed me of 4 recalls! what is Nissans standards for selling "certified" used vehicles??? I feel robbed. I hate my car, I dont want it, I dont feel safe!.
