I’ve seen at least a good 4-5 springs failures posted about here over the last month, and also if you Google it lots of “GM Tech” type pages come up with service techs discussing cars that have failed at their lots. That being said, all of them seem to happen under 1,000 miles, with the vast majority I’ve read about being in the first couple/few hundred miles.... and I think I’ve only read about one or two C8s that broke just over 1,000 miles.
Me, personally, I sort of have the 2,000 mile mark in my head for a “coast is clear” threshold. Obviously not very scientific haha.
