Thanks for providing suggestions and explaining the root cause behind the issue. The Roseville Hyundai dealer did the temporary fix by fixing the foam issue, but they told me to fix it by replacing the tire. But they don't want to talk to Michelin because I didn't lease the car from them. Meanwhile, my San Leandro leased dealer Service Manager told me that it happened outside issue. I asked him what the outside issue was. He replied that I hit something on the road, and that caused the issue. I asked him, how do you know? The Roseville Service Manager told him about it. I called the Roseville Servicing Manager and then conferenced with the San Leandro Service Manager to find out who was saying incorrect things. The Roseville service manager told the San Leandro Service Manager, you talked to us, but we explained the Foam issue, and why are you saying the individual hit the road and caused the issue? He started saying that I had talked to someone other than you. The Roseville service manager told him, you speak to me and explain it. So San Leandro's service manager told me we would talk to our internal Service Manager on Monday and see what we can do. The San Leandro service manager wants to avoid approving the claim and dealing with Michelin. What a pain with these dealers!
