yes, i have. after 2 weeks of owning the car they had to replace the computer. that took almost a month. then a month after i had the car back the shifter assembly came off. they had to redesign it and it got stuck in customs coming from japan. the way i look at it, gm pays for a rental car and you save the miles on your own car...not to mention, i called gm on the lemon law and they doubled my warranty and gave me $1500 to keep the car.
