### Penalties

Prior to the race, NASCAR confiscated the louvers (the hood radiator duct) of all Hendrick Motorsports teams and that belonging to Justin Haley (Kaulig Racing)'s car. On March 15, 2023, NASCAR punished all five teams with $100,000 fine and deduction of 100 driver and owner points each, as well as 10 playoff points and four-race suspensions for the respective crew chiefs, as the modifications were deemed to be an L2 violation. For the No. 9 team, only the owner points were affected as Josh Berry competed as a Xfinity Series regular and thus cannot score or lose points in the Cup Series, while Chase Elliott's driver points remain unaffected as he sat out of the race due to an injury. For Hendrick Motorsports, it was the largest fine imposed to an organization as a whole at $400,000, breaking the fine imposed to Michael Waltrip Racing in 2013 ($300,000) for manipulating the finish of the 2013 Federated Auto Parts 400.
Following an appeal on March 29, 2023, the National Motorsports Appeals Panel upheld the fines and crew chief suspensions for all of the Hendrick Motorsports entries, but rescinded their point penalties giving them back the 100 driver & owner points as well as the 10 playoff points that each team lost. Haley's penalty was upheld following his appeal on April 5, 2023, but the points penalty was reduced to a 75 point penalty. On April 6, 2023, Kaulig Racing announced they would move to a final appeal hearing with the National Motorsports Appeal Panel, after team president Chris Rice hinted on NASCAR Race Hub the evening prior that they would do so. On April 18, the NMPA overturned the points penalties at the request of NASCAR, who asked them to amend their appeal decision to be more in line with Hendrick Motorsport's appeal decision.
Additionally, Denny Hamlin was fined $50,000 and docked 25 driver points for his collision with Ross Chastain, after he admitted on his Actions Detrimental podcast that the collision was deliberate. Hamlin appealed the penalty on April 6, 2023, but the National Motorsports Appeal Panel upheld the penalty. Two of Aric Almirola's crew members were also suspended after his right-front wheel fell out during the race.
