Sport and Track Mode Vibrations
Please help, I recently took my 2018 2SS (manual) on a drive and noticed a slight vibration upon entering sport mode. After noticing the vibration, I felt the same issue in track mode, just a little more aggressive. The vibration is intermittent but is mostly felt when initially entering Sport and Track mode. I took the car to a dealer for diagnostic but they couldn't find anything.
Some more details on the issue: only felt at speeds between 60 - 80 mph (1500 - 2000 rpm), high frequency vibration, low frequency sound, vibration still occurs while car is coasting in neutral (between 60 - 80 mph), and vibration is not evident when vehicle is stationary at same rpm range. The vibration is intermittent (but rare) in touring mode and is non existent in snow/ice mode.
If you have any ideas, please shoot them my way. I've been trying to figure this out for the past couple days now.
