Camaro swerving

My car is swerving when in high speeds. Took it to the dealer they just said it needed an alignment, I can still feel the problem a little

How high is high speeds?
What do you consider swerving? Just drifting out the lane?
The summer tires on these cars will follow any imperfection on the highway so that may be what you are feeling.

70pmh on highway. Yes it moves out of the lanes dangerously. I can feel it. I'm thinking about taking it to good year since the dealer didn't really give a damn last time

maybe you have too much powaaaaaaaa and need some better tires?

Post the alignment.

Stock tires and wheels?

Have you ever hit anything? I hit a large rock and did a lot of damage to the vehicle. The power steering rack bolts had sheared. It took 3 tries and 6 weeks for the dealership to figure out the problem. I could feel the car "jumping" across the lane as I was on the freeway. It would dart suddenly without any steering input from me. I could also here a "clunk" when parked, and just turning the steering wheel a little bit. This was the sound of the steering rack hitting its mount because the bolts were sheared. The bolts are captured into the mount, so the steering rack will stay in place. However, if they are broken the ability of the rack to do its job will suffer drastically.

Secondly, I recall awhile back that there was a service bulletin for electric power steering assist software. There was a possibility that the EPSA would overreact to a steering input, or give steering input without the driver's input from the steering wheel. Check into this and see if your vehicle needs to have its EPSA software updated.

A quick search says the power steering had this TSB

Is the swerving always above 70 mph or just here and there? It's possible if you have 305's or larger tires the lane grooves in the road can pull you left/right. Happens to me all the time with my 305's and also with my Jeeps 37' tires.

This could be it as well. "Tram lining" can even occur with the stock sized tires. I can feel it just a little bit with stock size tires, but that's also in part because Michigan roads are complete trash. As OP explains he can "still feel the problem a little" it may just be tram lining.

With cooler temperatures check the air pressure in the tires too. My Camaro trams more when the air pressure is low even if it isn't low enough to trigger the dash warning.

This is basically a continuation of this thread:

There was also this. Sounds like the OP may have been running tire pressure on the low side:

How many miles are on these tires and what's the tread depth?
Another possibility is the hard sidewalls of the run-flats are contributing to that squirrely feeling.

What part of Florida and what roads is OP having trouble with?
