This problem is definitely Flash related and it seems to happen when certain advertisements are served up. In Chrome, you can disable plug-ins for this site only which seems to have fixed my "Aw, Snap" problem - at least so far.
In Chrome, go to the main menu and click Settings. Scroll down to the bottom and click Show advanced settings. Scroll down a little more and under Privacy, click Content settings. Scroll down to where it says Plug-ins and click Manage Exceptions. Under Hostname pattern, type in www.turbobuick.com and change the Behavior to Block and click Done a couple times.
See if that works. I just changed my settings and so far haven't had the problem anymore.
Keeping my fingers crossed, so far this fix seems to be working!!!
