Larson was in contention for the win at Charlotte in the Bank of America 500. While running second with less than 110 laps to go, Larson was about to stay out of pit road for a lap but changed his mind at the last second, entering pit road. At the same time, Kyle Busch was about to pit but changed his mind at the last second also and tried to stay out. Both cars collided as a result, spinning Larson and eliminating them from contention for the win.
During the press conference, Larson stated, "You grow up watching the NASCAR guys then you're like, ‘wow’ when you meet them. And then watching the guys in different series there's a 'wow' factor to meeting them and working with them." In his Rolex 24 debut, Larson's car stalled, and received a speeding penalty, but finished his stint with a fifth-place finish.
Larson returned to the 02 for the 2015 event, though Franchitti was replaced by Larson's Cup teammate Jamie McMurray, and the team ultimately won the race.
Following financial issues with co-owner Steve Turner that led to the dissolution of Turner Scott Motorsports, Scott found a new partner in the team, Chip Ganassi (whose drivers Kyle Larson and Dylan Kwasniewski drove for TSM), to field a single Xfinity Series entry under the name HScott Motorsports with Chip Ganassi.
Kwasniewski did not return to the team due to lack of sponsorship. Larson began with an eight place finish at the season opener at Daytona.
Larson's mother is Japanese-American, and her parents had spent time in a Japanese internment camp. Larson is currently dating Katelyn Sweet, the sister of NASCAR driver Brad Sweet. Larson announced on June 13 that he and Sweet were expecting a child. On July 16, 2014, Larson announced that the baby is a boy. On December 22, 2014, Larson's son, Owen Miyata Larson, was born.
