Since shortly after the vehicle's purchase, I have experienced a persistent, recurring, and unresolved defect in the vehicle's brake hydraulic system. Specifically, after the vehicle has been stationary at a traffic light or stop for a period of time with the brake pedal depressed, the brake pedal progressively sinks and travels to the floor under steady foot pressure, causing the vehicle to roll forward against my intent. This condition occurs under normal static brake application â not during active braking maneuvers. Normal braking function appears unaffected during active driving, but the pedal sink and fade condition under sustained static pressure constitutes a loss of hydraulic…

At the time of the incident, the panoramic sunroof was fully closed and the interior sunshade was open .

The turn signal flasher sound is so low that it is practically inaudible while driving and sometimes left on without notice. This confuses the cars from behind. Even worse, it confuses cars at the opposite direction in city driving. I have had a couple of incidents at busy intersection that the opposite direction car drivers thought I want to make a left turn but really not. The situation is getting more dangerous on highway driving. With the turn signal left on without hearing the audible sound, cars from behind would think that I want to change lane. Some good drivers would slow down but some aggressive drivers would speed up and pass at very high speed. One would ask the turn signal…

Transmission. Transmission has very rough, "jerky" shifting when downshifting and upshifting. There was a bad 'jerk" when downshifting from 5 to 4th gear. Dealer acknowledged the problem and provided a transmission software upgrade. The problem was somewhat alleviated but the transmission still exhibited rough shifting, both down and up shifting. More concerning occasionally, when turning a corner and coasting, sometimes the vehicle would surge ahead moderately because of shifting. Some criticism state that the brakes will "grab' occasionally. I originally assumed that this problem was the brakes, but after some experience realized that the rough and "jerky" shifting was responsible. I've…
