The No. 78 Toyota of race winner Martin Truex Jr. and the No. 48 Chevrolet of Jimmie Johnson failed post-race inspection Sunday following the opening race in the Chase for the NASCAR Sprint Cup in Chicago.
Both cars failed during both trips through the Laser Inspection System (LIS). Any penalties will be announced later in the week, according to NASCAR.
“It is what it is,” No. 78 crew chief Cole Pearn said post-race in the Sprint Cup garage. “Kind of a bummer on the day, but whatever, you know. We’ll move on. … It’s just really tricky. It’s just the repeatability. Things relax. It’s not the stiffest suspension back there, by any means. You try to account for that and prevent it and we missed it. We missed it two weeks in a row, which is kind of crappy.”
Previous LIS violations have produced either 10- or 15-point deductions during the regular season. NASCAR recently updated its rules for “encumbered” victory penalties during the postseason, but those would not be in effect for Truex Jr. because it was the lowest grade of failure for the LIS platform.
Kyle Busch’s No. 18 Toyota failed its first trip through the LIS platform, but passed the second. That does not equal a failed post-race inspection.
Additionally, the No. 16 Ford of Greg Biffle was missing one lug nut after the race and the No. 43 Ford of Aric Almirola had a broken stud.
The Nos. 78, 22 (of Joey Logano) and 24 (of Chase Elliott) will undergo further scrutiny at the weekly post-race inspection at the R&D Center in Concord, North Carolina, on Tuesday. That event will be live-streamed on NASCAR.com.
