During a caution period on lap 160 of the 2012 Daytona 500, a defective rear suspension on his No. 42 Chevrolet inexplicably collapsed, sending Montoya careening into a track support vehicle towing a jet dryer. Leaking vapor from the dryer caught fire and led to a lengthy red flag. The driver of the support vehicle and Montoya were both cleared medically after the accident.
