The No. 42 Chip Ganassi Racing Chevrolet of Kyle Larson failed post-race inspection Sunday at Michigan International Speedway following a third-place result.
According to NASCAR, the No. 42 failed at the laser station.
Larson had an interim crew chief in Philip Surgen this weekend. Full-time crew chief Chad Johnston was suspended for this weekend's race after the team was issued a P3 penalty for lug nut violations at Pocono Raceway.
A NASCAR spokesperson said that any penalties would be announced later in the week.
There were no other issues in post-race inspection at the track. The No. 22 Team Penske Ford of race winner Joey Logano and No. 24 Hendrick Motorsports Chevrolet of runner-up Chase Elliott were cleared at the track, and they'll undergo additional teardown on Tuesday at the R&D Center (which will be live-streamed on NASCAR.com, starting at 8 a.m. ET).
Three random cars also passed post-race inspection at the track -- the No. 2 Team Penske Ford of Brad Keselowski (finished fourth), the No. 3 Richard Childress Racing Chevrolet of Austin Dillon (finished eighth) and the No. 4 Stewart-Haas Racing Chevrolet of Kevin Harvick (finished fifth).
