Yes, first year issues do come up (as they have for years). Some companies (like Lexus) handle them better and still have fewer than average. Other companies (like Ford) have far more first year issues. Better and more thorough durability and reliability testing prior to production release makes a difference, even Mercedes has proven that (after years of terrible reliability in 2000-2007 ). New GS350 issues have yet to be documented, maybe they will come up but too early to say.
