On lap 149, during a caution period, Bobby and Mario Andretti made their pit stop and headed back to the race. Bobby passed eight cars during the caution, while Mario passed two cars. Unser won the race, but was stripped of it the following morning in favor of second-place finisher Mario Andretti. After a 5-month lawsuit and protest by Penske, Bobby Unser was re-awarded the win in October 1981. For his infraction, Unser was instead fined $40,000 ($ in today's money).
