Vehicle was shaking when accelerating, the issue is coming from a faulty transmission shudder on all 8 speed automatic transmission sold by General Motors. My safety was at risk due to very bad shaking that almost felt like the car was going to break down at highway speeds. The issue has been covered and fixed under my vehicle warranty, but may re appear according to sources online. There were no warnings to let me know that there was an issue with the part.
