wow,same story like everyone else I also have an 2002 nissan altima. the first one was also a 2002,the dealership cleaned it up topped off all fluids. I drove home,as i drove i felt like someone was pulling the car backwards it just wouldn't take off like i no it could. I took it back 2 the dealer the next morning they claimed they don't know what happen they took it back 2 b serviced they said they topped off all fluids.they said everything is good.
