Bergey's Chevrolet

I purchased my Chevrolet Equinox, 2018, in December of 2019. The vehicle is great except a few main issues. I noticed my tires were bald after only driving the vehicle a few months. Bergey's replaced the tires, paying for two of them while I paid for the other two, being that the vehicle only had 15,000 miles on it at time of purchase. The big issue I'm having now is the paint on the front hood is bubbling in multiple spots. This will likely peel and eventually rust needing to be buffed/ painted or completely replaced. This is not acceptable for a vehicle that is only three years old. I emailed Joanna Bergey and have not heard anything from her yet. I contacted Chevy on my phone app. They said that my bumper to bumper warranty was expired at 35,000 miles, my vehicle has 40,000 miles currently. This potential rust should not be present and is a manufacturer defect and should be replaced/repaired at no charge to myself. I do not drive much on highways so I have no idea why this is happening. This issue needs to be addressed before the rust starts. I have pictures also.
