general problems of the 2009 Audi A4

I own a 2009 Audi A4. On the month of October 2024 my transmission failed. I towed my car to a mechanic who then replaced my transmission I picked up my car on December 11 2024 at 7 am from Audi of fresno. I have had no prior issues and like always I expect a dealership to inspect a new vehicle that comes in ,as I have never been able to get work done with out them always doing their own diagnostic. Any ways . On the morning of December 20 at 8:15 am I went to pic up breakfast from carls jr with my boyfriend . As I placed my order and drove up to the window without a single warning my car engulfed in flames from the front driver side . I turned my car off jumped out called. The fire department and watched as my car continued to build flames until the fire department finally showed up. Had I taken the freeway thay day instead of the streets I wouldnt have noticed the fire untill it was to late. . Im in shock and also just pissed that something like thus happened.
