Newly released 911 records show that Kyle Busch was short of breath, overheating and coughing up blood during a medical emergency at a General Motors training facility in Concord, North Carolina. The emergency happened Wednesday, one day before his death. The May 22, 2026 records gave the public the first detailed account of the crisis that preceded the loss of the two-time NASCAR Cup Series champion.

Busch was testing in a Chevrolet racing simulator when he became unresponsive and was transported to a hospital in Charlotte, according to people familiar with the situation cited by the Associated Press. The emergency call came from the General Motors facility late Wednesday afternoon, as staff sought urgent medical help. Simulator work is a routine part of modern Cup preparation, especially before Charlotte, where teams use manufacturer facilities to refine setup choices before a long and physically demanding race.

"I've got an individual that's (got) shortness of breath, very hot, thinks he's going to pass out, and is producing a little bit of blood, coughing up some blood," the caller told dispatch.

Audio released by the Cabarrus County Sheriff's Office also said Busch was lying on a bathroom floor inside the complex and was awake when the call was made. The caller directed responders through the facility and asked that sirens be turned off on arrival, a detail that underscored both the urgency of the call and the controlled corporate setting where it unfolded.

Emergency Call Timeline

The timeline places the medical emergency during one of the sport's busiest weeks, just days before the Coca-Cola 600 at Charlotte Motor Speedway. Busch had been scheduled to compete during the weekend and had also been entered in a NASCAR Trucks Series race. His death on Thursday sent shockwaves through the racing community and changed the tone of the entire race week in Concord. For teams already operating on tight practice, qualifying and sponsor schedules, the release of the call shifted attention from competition planning to the circumstances of a sudden medical crisis.

No official cause of death has been released. Busch's family previously said he had been hospitalized with a severe illness, but the public record has not yet identified a final diagnosis. Medical investigators are expected to review the emergency call, hospital records and any additional findings before issuing a formal conclusion. Until that process is complete, the 911 material should be read as a contemporaneous emergency record rather than a medical explanation for what ultimately happened.

The records also clarify what can and cannot be concluded. They describe serious respiratory symptoms and a rapid emergency response, but they do not establish the underlying medical condition. That distinction matters because the 911 audio is evidence of the crisis, not a final medical ruling. It also leaves open basic questions about timing after the ambulance transport, including when hospital staff received him and what clinical findings shaped the later family statement about a severe illness.

NASCAR Response

Richard Childress Racing said it would retire use of Busch's No. 8 Cup Series car for now and run the No. 33 instead, while reserving the No. 8 for his son Brexton when he is ready to race. The move shows how closely Busch's identity had become tied to that number during the final stage of his career, and how carefully the team is handling public symbols after his death.

Busch won 234 races across NASCAR's three national series, the most of any driver. His final victory came the previous week in a Trucks race at Dover, and he had finished 17th in the All-Star Race on Sunday. Those recent appearances made the sudden medical emergency even more jarring for drivers, fans and team personnel. They also made the 911 release significant because it connected a driver who had just been active at the track with a private medical episode that unfolded away from public view.

The newly released 911 call does not answer every medical question, but it clarifies the urgency and severity of the emergency that unfolded before his death. It also explains why the response at the GM facility has become part of the broader record around Busch's final days.
