Possibly. I have looked at that product before. I'm hesitant to do anything aftermarket yet, so GM won't have an excuse to deny coverage or a buyback if I go that route.
GM contacted me again and reiterated there is no fix for the condition and "engineering is working overtime" to resolve the problem. Was also advised that the tires are not the problem, and although some tires perform better, the underlying condition is not corrected and not to replace them.
What I'm really concerned about is the wear and tear on the steering and front axle from the shaking. If I can feel it through the steering wheel, which no doubt suppresses it because of the programming and power steering, how is this affecting the long term life of those components?
Drove 300 miles yesterday, and my hands were literally shaking when I got home due to the vibration. Very, very disappointing at this juncture to say the least.
