2013 AUDI A5 Unknown Or Other Problems

I was having an issue with my 2013 Audi A5 starting. A call to roadside assistance was able to jump my battery and the car would start and run. However, the same issue kept happening. The EPC warning light would come on and it took a few weeks to get scheduled with a mechanic. I purchased a mobile jump starter myself because I never knew when the car would or wouldn't start. After taking the car to Audi, they found the "transmission coolant valve failing internally causing coolant to migrate up connector - this is causing a short which is draining the battery. If not fixed it will continue to deplete the batter. Recommend replacing valve and and connector".

THE SUNROOF EXPLODED. I WAS DRIVING AND HEARD A LOUD NOISE. I LOOK AROUND BECAUSE IT SOUNDED LIKE A TIRE BLOWOUT. I CONTINUED TO DRIVE, AND ONCE I REACHED MY DESTINATION, STOPPED AND OPENED THE DOOR TO EXIT THE VEHICLE, I HEARD A LOUD POP LIKE A GUN SHOT. IMMEDIATELY GLASS FLEW EVERYWHERE. I WAS LOCATED IN THE PARKING LOT OF PICADILLY RESTAURANT WHEN THE EXPLOSION OCCURRED.
