In 2012, Kenseth's primary sponsorship was split between Best Buy, Zest Soap, and Fifth Third Bank, although the team was still forced to run several races unsponsored. Kenseth started the year strong by winning the Gatorade Duel Qualifying Race and the 2012 Daytona 500, which was also Jack Roush's 300th victory in NASCAR and his second Daytona 500 victory. It was later announced that Kenseth was leaving Roush Fenway Racing after the season, even though he had no team he was going to. Kenseth made the Chase and won two of the ten Chase races (Talladega and Kansas), finishing seventh in the standings. Following the season, Kenseth joined Joe Gibbs Racing in 2013.
