I have owned the car for a little more than a year, and it has 72,000 miles on it. The only problem I have had is this: After idling at a long stoplight while in drive, started into intersection, trans lost all ability to transmit power, engine just revved. Pushbutton selector, tried all other gears, no result. Pushed car to parking lot. Checked trans fluid (in neutral with engine running) and it was at the correct level. Sat a while to think (5-10 minutes). Tried it again, and it worked fine. Drove home about several miles with no problems. Otherwise, I have not noticed any other problems, no shift issues that I noticed, no slipping that I noticed.
