Each of the Stewart-Haas Racing cars had issues clearing NASCAR technical inspection prior to Saturday's qualifying session at Talladega Superspeedway.
According to a NASCAR spokesman, there was an issue with the radiator inlets on the cars of Kevin Harvick, Kurt Busch, Danica Patrick and Tony Stewart.

The teams were forced to change out the part prior to qualifying, but all four cars eventually cleared inspection and NASCAR did not confiscate any parts.
According to the NASCAR spokesman, any possible penalties would be announced early next week. If the penalty results in a loss of points, it could have a big impact on the championship hopes of Harvick and Busch if they are able to advance to the Eliminator Round of the Chase.
If that is the case, the spokesman said the appeal process would be expedited and would likely take place prior to next weekend's race at Martinsville Speedway. Earlier this year, NASCAR expedited Kurt Busch's appeal after he was suspended ahead of the Daytona 500, getting it done over the course of an afternoon.
