At the 2012 Belgian Grand Prix, Grosjean was involved in a multiple car pileup at the start of the race, resulting in Grosjean, Lewis Hamilton, Fernando Alonso and Sergio Pérez all being eliminated from the race and Kamui Kobayashi missing out on a possible podium after starting from the front row for the first time of his career. The incident was started when Grosjean collided with Hamilton on the approach to the La Source corner. After the race, Grosjean was issued with a one race ban covering the next Round at Monza. He was replaced for the race weekend by Lotus reserve driver Jérôme d'Ambrosio.
