The No. 45 started smoking and laying down oil going into turn 3 shortly after pitting during a green flag cycle.
Reddick stopped down on pit road, with oil and fluid all across the right side of the car and on the windshield.
A 23XI Racing crew member told TNT that "something went through the radiator" that caused the issue.

NASCAR threw a caution for a lengthy clean-up for fluid on the track. The No. 45 team worked to fix the radiator and related issues in the garage.
Reddick's spectacular start to the 2026 season finally hit a road bump in June after a DNF at Michigan, a late-race tire failure at San Diego and a power-steering failure at Sonoma.
Denny Hamlin took the points lead from Reddick after Sonoma, the first week in which the 23XI Racing driver did not lead the standings.
