Crankcase (pcv) problems of the 2012 Volkswagen Jetta

The first thing I noticed after driving the car was the smell of burning oil occasionally, then upon opening the hood and removing the engine cover there was minor oil seepage from the valve cover. The car itself is 2012 Jetta gli and only has about 27,500 miles as I type this message. But it gets worse, I notice the oil level dropping and having to put refill it about 2 or 3 times a month. At this point I know something isnt right and its not just a faulty valve cover gasket. Did some reading online and I suspected it was a faulty oil separator/pcv system creating too much crank case pressure. I also checked the rear main seal recently and see oil leaking between the motor and transmission, suggesting the rms has began to fail. My question is if the car was "certified pre-owned" and pcv valve failure is some what common for both tsi and fsi engines, why wasnt the vehicles pcv inspected for failure or changed entirely with the new revision? there are many revisions on the oil separator/pcv valve from what I see. Shouldn't the damage to the rms replacement be covered by the manufacturer since it was due to premature failure of the oil separator, that is known to be prone to failure or faulty from the factory? currently im not driving the car and waiting for the newest revision of the oil separator but since the rms has already began seeping oil its only a matter of time before it fails completely. Being a trade school student who is lost his job right before christmas last year this unexpected failure of the rear main seal at only 27,500 miles, regardless of vehicle age is unexpected and at a severe inconvenience. If Volkswagen cannot provide at least the labor cost for the rms replacement I cant say ill ever buy another vw from a dealership again.
