Q Parker from 112 came under siege on Father's Day when his expensive ride was snatched during an ATL pit stop.
The singer tells TMZ it all went down Sunday morning on his way home from the airport after a show in Philly. He pulled into a gas station in College Park, Georgia to check a tire that was low on air.
He says, out of nowhere, someone jumped into the driver's seat. Q says he tried to make his way back into the car, but the thief -- who Q says looked 14 -- floored it and took off.
The $90k Audi A8 is still missing, and there are no suspects ... but there's a popular 14-year-old out there.
