At the first race of the season, the season-opening 2018 24 Hours of Daytona, the updated cars endured a mixed qualifying, on their return to competition, the #55 coming in 9th overall in the Prototype field, 5 tenths off the pole-sitting #10 Wayne Taylor Racing Cadillac DPi-V.R, while the #77 did not set a lap, after the Joest Racing team observed something an oddity in the telemetry. The race was no better for the team, with both cars hitting trouble early and being unable to recover, the #55 retiring after a major fire, and the #77 later suffering gearbox issues amongst other things. Both cars failed to make it to the finish, which left the team with a much-reduced mileage compared to their class rivals, many who successfully made it to the chequered flag.
