You got super lucky. That's the kind of failure that can kill you easily by throwing you into oncoming traffic.

That's terrifying. Was this a Certified used vehicle or just a random on the lot?

Most factory CPO programs exclude accident vehicles (beyond simple bumper cover resprays from incompetent parallel parkers).

That's what I thought, guessing this wasn't certified. I put a lot of trust in certification programs. Also I should mention as a counterpoint to a "wrecked car" I have a "wreck" on my 2019 that didn't do anything but scratch my bumper while totaling the other car (8mph impact but steel bumpers) and has plummeted my trade in $8k.. sucks. I didn't even claim any insurance work or anything on it.

I wonder if I can somehow get that removed if I take it to get checked out at a frame shop, it's a brand new Jeep and this going to follow it everywhere. I don't recall ever hearing about people removing wrecks, though. Not trying to title-wash but prove that it's fine for the next buyer.

I honestly don't remember at this point.

It's always a good idea to thoroughly examine every detail of a used car before trusting it at high speeds on a highway. Sounds like it might have been quite difficult to detect this particular problem though if it was a barely visible hairline crack that just got worse over time. scary.
