Hi, I have a new 85D (19" standard wheels, air suspension). I am experiencing a brief steering/driving instability that I wanted feedback on. It is a pretty pronounced instability that can be felt only when the car makes a rapid transition from (1) speed to higher speed (eg punching it at 50mph) and (2) high speed to lower speed (eg rapidly lifting my foot off the accelerator when going 70mph). It seems to happen when the car is shifting its weight from front to back and back to front. The instability feels like the whole vehicle is momentarily (less than a second) out of control and is imbalanced while the weight transitions. - tire alignment seems fine, on smooth surfaces I have no consistent drifting to one side or the other. - it doesn't seem to matter if I'm in range mode or not. Any thoughts / feedback would be awesome!
