Other Fuel System Hoses Lines/piping, And Fittings problems of the 2003 Chevrolet Impala

There are 3 recalls I have found that possibly are effecting my 2003 Impala but because my specific VIN # doesn't fall under any of these gm is refusing to fix these problems. 1)the body control module needs to be reset. Apparently when it goes out the cruise control disengages. . . . . And my cruise control light is on but won't engage. Plus my mechanic says the body control module also is what is could be causing my heater fan to not work nor my information display to work. But low and behold when the cruise control light goes off they both work 2) there is a recall stating drops of engine oil may leak on exhaust manifold with hard braking and I sometimes smell oil burning after I drive. If it was my actual engine leaking oil I would smell it all the time but I don't it's just after I drive certain places that are very congested and I brake a lot 3) there is a fuel vapor leak from the gas tank which is believed to be causing my check engine light to come on. It throws the code stating I need to possible replace the gas cap (which I have done) and only comes on after I have put gas in the car. I'm alittle concerned and applaud that just because my VIN # doesn't show these recalls but Impalas are having these recalls that gm won't fix these problems.
