Tank Filler Pipe And Cap problems of the 2007 Suzuki Forenza

We just bought this car in August 2012. Since then my seat belt button turned on and took it to the Suzuki dealer and they fixed it. Also the passenger air bag also and they fixed it. Then took it to the dealer to get the oil changed and they said I had a radiator leak ( I wonder how true was that sometimes) repaired it and it cost $400. . . . Now when I was driving the car check engine light turned on and now it was the gas cap that needed to be replaced!!! wth so we replaced that part. Now after we fix that, guess what also starts happening the car just starts to slow down and again check engine light turns on!!! we take it to get a diagnosis and it gives us p0705 p0700 and that now is the transmission range sensor!!! this is crazy!! hopefully nothing else will go wrong. . . . . I feel that Suzuki should have a recall on this transmission range sensor especially. . As I see. . . Many people are going through this and people should be compensated for the money that we all have wasted and frustration we are all going through. . . . Suzuki needs to fix this problem. . .
