Makes me nauseated
 Transmission shifting issues - shifts so jerky it will actually make me car sick.  Have had back to dealer 2x for updates, shifting improved, but not even close to acceptable for any vehicle, but this one is $40k+.  Dealer told me fix is to shift manually - no thanks, I didn't buy a stick shift.  Live in western PA, lots of hills, car will not shift out of 2nd gear starting up a hill unless speed exceeds 25 mph - that's about 3500 rpm. When you take your foot off the gas, it throws you like hitting the brakes!  Terrible engineering from a premier automotive company.
