How many out of how many have the rear end whine and safe mode crap? Is this to be expected on the majority of them? God I don't want issues. I have had terrible trouble in the past with GM's lack of Customer Service. I sued them and won, don't think they like me. I had coverage on TV and news papers, they just paid me off to shut me up. Thought I would try the Goat since I have a 65 389 tri power.
