2021 Dodge Charger Wheels Problems

My rim on the inside lip has a hairline crack. I’m coming up on 1 year and for the entire time I have had to add air once a month. The tire pressure would be 38 psi when I put air and would drop to 30 over a months time. I’ve had the tire looked at several times and they found nothing. Then around 3 weeks ago it went from loosing 8 psi a month, to around 5 psi a week. So I jack the car up and start looking, spraying with a soapy water and I find the crack.So I called the dealership, and they say well you hit a pothole or something in the road. No I did not, I’ve never hit anything. If I did the rim would be bent or have scuff marks, which theirs not. So I do research and find out I’m not alone. As of now January 16, 2023 I’m loosing 15-20 psi a day. Thank you
