07 RL 28,000 miles - only when stopped in drive does steering wheel vibrate. a/c increases the vibration. Does not happen all the time - twice to Acura dealer and could not duplicate problem. This week ran into local Honda dealer under vibration - they suggest replace front and rear motor mounts. Thoughts? What is the going price to replace 2 or 4 motor mounts? XLR8 kit?

 

If it's engine mounts - it could be cover under powertrain warranty. Mine was changed under exteneded warranty ~80K miles. I would confirm with your Acura dealer.

 

I didn't recall noticing any steering wheel vibration on mine. If it is engine mount - usually it will get worse as you gas it more vs. at idle.
