When do the problems End?
Maybe I am fortunate, I have not had issues so far in all my vehicles (Mercedes, Cadillac, Lexus). Sometimes I made mods that created heartaches (wheel spacers), but i learnt through those mistakes (never make wild mods to your new vehicle).
The noise/ inability to hold the conversation over 80 mph, I believe that is just the "road feel" - strangely these days people pay to get that
That said I like my car quiet (devoid of road feel). Lexus is amazingly good in that (super quiet cabin), but then most dont buy Lexus (precisely because it is too quiet with no road feel 
hope you get your car adjusted soon to your liking.
My personal experience has been different. I owned a 2015 C300 Sport for almost 7 months. In my case, my car was plagued with repeated mechanical problems that it was eventually deemed a "lemon". I now drive a 2015 Lexus IS350 F Sport. It's more of an athletic driving experience than the C300. Plus, Lexus customer service is hard to beat...
That's why I waited until almost the year end run for my 2015 C300.
Fortunately for me, the only problem I've had with my 2015 was a right rear tire that was replaced under warranty. Service too has been excellent at this new Mercedes Benz dealership in Burlington, MA.

Your suggestion that Lexus ranks low in build quality seems to contradict every recent published study on vehicle quality and reliability. I reviewed the JD Power IQS for the 2006 Lexus GS300 and it scored "above average" in the first year of the model redesign. This is not to say that you did not have problems with your car. However, the GS300 (for that year) ranked higher than the W205 2015 C Class which scored in the bottom percentile in this year's IQS.
Lexus consistently leads all luxury brands in awards for Initial Quality, Dependability, Customer Satisfaction, Dealer Experience and Resale Value. In 2015, Lexus was ranked the top automotive brand by Consumer Reports which considers both performance, reliability and safety.
