Andretti finished third at Iowa, and then ran a strong race at Richmond but lost position when he pitted under green and a subsequent caution allowed the race leaders to pit under yellow; he finished ninth. Andretti finished fifth at Watkins Glen, before mechanical failure caused his car to crash out at Nashville. He also raced earlier the same day in the American Le Mans Series race at Lime Rock Park. At Mid-Ohio, Andretti got caught up in a four-car wreck on a restart on lap 42 which ended his race, before a 17th-place finish at Edmonton after contact with his teammate Danica Patrick. At Kentucky, Andretti took the lead from Scott Dixon, but as the race neared its end, all drivers had to pit for more fuel and Dixon took the win, while Andretti finished third. Andretti failed to finish higher than eighth in the final three races, as he finished seventh in points.
