Test drive before purchasing was stopped after a 1/4 of mile because of heavy front end shaking. Dealership changed tires saying that would fix the problem. Since then it has also fixed front end alignment twice, changed the driveshaft and two rear axles. Vehicle still shakes. Vehicle is perilous to drive on bumpy surfaces when driver has difficulty controlling front end.
Car unresponsive to inputs from the accelerator pedal. Multiple dashboard warning lights - vsm off, dsc, epb, psb, airbag, and check engine lights; vehicle still running. The first instance occurred on a freeway feeder road while going 45mph; car was unresponsive to any inputs from the accelerator for approximately 10 seconds, simply acting as if there were no throttle inputs. Turning to head home immediately, the vehicle responded similarly while traveling 25 mph on a residential street; it began coasting and any throttle application resulted in no acceleration. Car limped home and parked for dealership tow truck.
