Carl Edwards won the race, his first of the season, while teammate Ricky Stenhouse Jr. finished second, while Aric Almirola, Tony Stewart, and Marcos Ambrose rounded out the top five.

On the final lap of the Kobalt 400 at Las Vegas Motor Speedway, Dale Earnhardt Jr. ran out of gas exiting turn 2 and Brad Keselowski passed him to take the checkered flag.

[12] Earnhardt Jr. was disappointed with the way that his race finished, describing running out of gas as "tough", while stating that he and his team "have got a good thing going, we've got to be positive.

[14] Kyle Busch and Greg Biffle were involved in a similar situation in the same session,[14] while Justin Allgaier bounced off the turn 1 wall, having believed he had blown a right-front tire.

He apparently ran over a battery pack that came off a car well in front of him, while his hood pins were carrying what appeared to be toilet paper.

Alex Bowman stalled on the apron in turn 1 and needed a push from one of the safety trucks to get back to pit road.

The fifth caution of the race flew on lap 156 when Cole Whitt came across the nose of Danica Patrick and got turned into the wall on the front stretch.

Two laps later, Kyle Busch made an unscheduled stop after making contact with Dale Earnhardt Jr. which he felt had caused a flat tire.

The seventh caution of the race flew on lap 276 after Ryan Truex hit the wall in turn 2, after a right-front tire blowout.

The race restarted on lap 339, and like the previous stint, Kenseth led throughout until the next caution flag – the ninth of the race – flew on lap 394 after Kyle Busch had a left-side tire go flat and spun out in turn 4, and was just clipped by his brother Kurt, which caused a similar puncture on his car.

Once again, Kenseth and Hamlin traded the lead on pit road, but on this occasion, it was Kevin Harvick who would exit as the leader for the restart with 97 laps to go.

The tenth caution of the race flew with 78 laps to go after Martin Truex Jr. cut down his left-rear tire, spun through 360 degrees and came to a stop at the exit of turn 2.

The eleventh caution of the race flew with 50 laps to go after Harvick had a broken gear that sent his car into the wall hard in turn 1.

[16] NASCAR vice-president of competition Robin Pemberton stated after the race that the organization "were scanning cars and spotters, and there's some of us in the tower that only heard it after the teams were talking about it because we were looking at other things around the racetrack".

[17] Edwards described his race as "awesome", after troubles on the previous day, stating that his car was "terrible on Saturday, so I'm just glad we turned it around".

[17] Ricky Stenhouse Jr. scored his best career finish with a runner up spot,[17] stating that he had "a lot of fun" and that his team was "just slowly working and getting better and better", as he continued to improve results in his second full season in the Sprint Cup Series.
