On June 21, 2009 in the Toyota Save-Mart 350, Busch was involved in a wreck with Jimmie Johnson. Three weeks later at Chicagoland Speedway, both Johnson and Busch were involved in another incident where they collided into each other.
Busch then retaliated by colliding with Johnson's car in the door area shortly after the contact. Over a year later, Busch was involved in a crash on lap 165 at Pocono's August race after bumpdrafting with Johnson.
His part was overshadowed by Elliott Sadler's violent hit into the inside wall in the same crash. Busch and Johnson were also involved on the final lap of the August 2011 Pocono race in which both made contact when battling for third place. The two would exchange words on pit road after the race.
Later in September 2011 when Busch was racing at the fall Richmond race after he and Johnson were told to settle down after Pocono; Busch accidentally made contact that resulted with Johnson spinning out in smoke. Almost 60 laps later, Johnson waited for Busch to come back around the track and intentionally retaliated by making contact resembling the previous spin.
Although it looked like Busch would avoid the result of crashing, Busch was spun around when avoiding another car during the contact. Johnson was black-flagged for several laps because radio communications proved that Busch's first contact with Johnson was not intentional.
After the race Busch, satisfied with his top-five finish, called Johnson "A five time chumpion" and said he was in Johnson's head always. He then shook hands with Johnson during the post-race ceremonies to put the incident behind both of them.
