I picked up my Ascent (Abyss Touring) about a week ago. There are approximately 800 miles on the odometer.
I've noticed that at high-speed (70mph+) I am detecting a subtle, fast vibration that is accompanied by a low-pitched drone. My immediate reaction was to have the alignment and wheel balance checked. The front toe was slightly off and both driver's side wheels needed a 10g weight to balance out. I also adjusted the cold air pressure to 33psi. I thought I had finally solved my problem.
Last night I decided to put it to the test and went for a drive across a variety of surfaces while varying my speed as much as possible. Unfortunately the vibration persists. It seems to happen most often when the engine is at 1500-2000RPM. Increasing the RPM seems to mitigate the problem although I have felt it at 2100+RPM. I wonder if I'm feeling the engine being lugged a little? Keep in mind this is a very subtle vibration. If staring at the steering wheel, it is not visible.
I've also noticed this to be most prominent on concrete road decks; especially those just completed near my home. Could it be that I'm just getting more feedback in the wheel than I'm used to? I have experienced this on smoother roads as well though.
Lastly, this might just be a perception thing. My last two cars were V8 and V6 respectively. The latter was so smooth it was almost undetectable when running. I don't mind the little boxer in the Ascent but compared to previous vehicles, it is not as quiet or smooth.
Also my last car had 40-series tires on 19in wheels and I don't recall there being as much feedback in the steering wheel.
Has anyone else experienced this?
