Now in the shop for the fourth time to fix the (apparently) unfixable Sirius satellite radio; entire radio failed once; engine valve clatter and transmission "clunk" is annoying, but not yet troublesome. Great car otherwise, but clearly not up to manufacturing and reliability standards of Lexus, Acura and the other "Pacific Rim" manufacturers whose cars I have owned in the past. Even more troubelsome than the two Mercedes we recently owned.
Design, performance, comfort, included maintenance.
The car is electronically challenged; Germany needs to be more involved with training local service techs - continuing problems very frustrating for $52,000 car. Does Germany keep the good cars and send us the bad ones? These cars should be electronically and mechanically perfect!! Needs better tires
