2010 GL450 Purge valve

Just bought my 2010 GL450 2 wks ago with only 400 miles in it. A bit disappointed because CEL came on las night while driving; called roadside assistance, gas cap was mentioned as cause, recommended to retighten it and CEL will disappear it 6-8 hours. The following morning CEL is still on, took it to dealer, and this was its findings: Mechanical Fault PUrge valve; TC found P2421 mechanical fault Y58/1, noted purge control valve was permanently open. Solution: guided test, remove hoses, replaced valve, cleared DTC, evap test passed.
I asked service advisor what has caused this:
--- not loose gas cap
--- faulty purge valve from factory

Now i am wondering given this brand, quality control shld be at best; and for something to fail this early...
Anybody out there has experienced this?
I hope this will only be the problem with my car from hereon, at least for several thousand miles...
thanks for your input.

I wouldn't worry about it. Your car has 4 years factory warranty. Typically if it breaks down too many times they will just buy it back from you. With that said though you should double check this with your MB dealer.
