I didn't find any solution and T-Fix didn't work. I posted about the issue here ...

I dropped off my car this morning and looks like they didn't find any fault codes.
I noticed that this happens on a hot day or after continuous driving for 20-30mnts. I am mentioning this because after the car is sitting in the sun or continuous driving, when I lock the car with key, instead of the regular feedback tone, there is a strange feedback tone. After the car cools down it is normal feedback tone. Both these issues maybe related to some cooling or electronics issue.
