I have a 2019 Blazer with 17K miles. It started to drip rust on the driveway from the front end. The spots are on both sides about 36 inches apart. Considering the amount of drops, water has to be pooling somewhere which looks like a big design flaw.

Did you have it rust proofed and undercoated when you got it?

I have a 2019 Blazer with 12k miles and live on the sun coast of FL and it sits out 24/7 and have not seen anything coming from the the bottom of the Blazer. I would take it to your local Chevy dealer and ask them to put it on a lift to see what’s going on?

Check for possible leaks. My blazer just had the radiator replaced due to a manufacturing flaw in welds / construction of the radiator

I took it to the dealer and after some back and forth, they replaced rusted hardware at the inner wheel wells near the center cross member. I believe they said it was bad bolts, but not totally sure.

Umm.....that sounds fishy. Bad bolts? What made those bolts bad? All of us would be experiencing that type of issue if it was a design flaw. Do you live up north with the salt for the winter or perhaps live on or off a muddy road or driveway? There's extra moisture getting in that area causing those bad bolts.
Then again, there are 60s and 70s era cars I've dealt with and even they, after years and years of exposure don't leave marks like that in the driveway.

Yes it does sound fishy which is why I posted to see if anyone else was having that problem. I live in Northern VA, it's only driven on paved roads, and while they do use salt up here, the Blazer is not old enough to be rusting from the limited exposure it's seen. No 2019 vehicle should be rusting like that I've never had a car rust like that...and I used to live in Michigan. Besides those bolts, and the trailer hitch cover coming lose (which was a recall), I haven't had any other issues. Given that it was the bolts on both sides and they started rusting at pretty much the same time, it's a bit concerning since the vehicle is approximately a year and a half old. What was on the receipt said "replaced rusted hardware at the inner wheel wells near the center cross member." I didn't see exactly what was replaced, but it doesn't appear to be dripping rust anymore.

You may want to give the bolts/bolt heads a shot of undercoat. Just a thought.

In general, if a car is designed in such a way that drops collect inside its body, then it was necessary to protect it from rust in advance. It is rather your mistake.
But I think the guys at https://www.rustbullet.com/ can still help you. They also dealt with much more difficult cases of rust accumulation in the hull.

You were your parents mistake, whats the difference?

Just curious, but did you open the hood and look around to see if you can find where the rust is coming from? Did the problem come back after the dealer changed the 'bad bolts'? My wife's Blazer isn't near by right now so I can't check, but what color is the antifreeze? If its orange-ish then it could be antifreeze. Good luck.
