This took place about a week ago. The car was parked in our driveway when the fire started. My husband had returned home just 15 minutes prior to the fire starting. I noticed there was smoke coming in our living room window. Then I looked at our security camas. And saw smoke pouring out from underneath the hood of my car. We tried to put the fire out with our two hose system set up and it wouldn't go out. So we knew it was electrical. We couldn't get close enough to open the hood so I couldn't pour baking soda on it. Two fire extinguishers later like 10 minutes the firefighters showed up and we're able to put it out. They confirmed that the arch came from the battery terminals /cables. Two of the fireman said they'd never seen anything like this before. Then the car tried to START ITSELF as my husband and the two fireman were standing right in front of the Audi. They had to cut the remaining battery cable that wasn't completely burned through before it stopped. My neighbor has a record

PRNDS appeared in red on my dash and then started blinking. Went on line regarding this and read about a TCM switch or a lever switch malfunction.Have an appt with mechanic on 8/26/21. From what I have read we are looking at a cost prohibitive repair of several thousands of dollars. Does Audi have any responsibility? Apparently it is a common complaint with the A4 model. Felt loss of power when decelerating.
