The Indian manufacturer was forced to withdraw Lucas di Grassi and Oliver Rowland in South Africa, as well as the customer Abt cars of Nico Muller and Kelvin van der Linde due to the issue.
Bertrand confirmed the problem centred around a wishbone on the rear suspension which had failed on both Mahindra machines and one of the Abt vehicles after FP2, leaving the teams no choice but to withdraw from the event.
