The C38 struggled at the next four races, failing to score points. Räikkönen's car retired from the Mexican Grand Prix with an overheating issue, and both cars were knocked out in Q1 in the United States. A successful result came at the chaotic Brazilian Grand Prix. Both drivers took advantage of retirements, collisions and penalties of cars ahead to score the C38's best result, with Räikkönen classified 4th and Giovinazzi 5th. The car returned to poor form at the season-ending Abu Dhabi Grand Prix, with both drivers failing to reach Q2 and to score points.
