Ford recalled Mustang vehicles built between 5 January 2021 and 30 March 2021.

The dealer will update the Image Processing Module A (IPMA) and the Power Steering Control Module (PSCM) to the latest available software level free of charge. You won't usually pay for it.1
What’s Wrong
According to Ford’s records certain Mustang vehicles may not have the remedy for Compliance Recall 21C11 installed correctly but were recorded as having received the repair successfully. Because the correct software update may not have been installed on these vehicles the underlying condition may still exist therefore these vehicles may still have the incorrect software loaded for the Lane Keeping System (LKS). On affected vehicles not having the latest Lane Keeping System (LKS) software may lead to non-compliance with the current regulations relating to Hands-On-Off (HOO) chime requirements that became effective from April 1 2021. Dealers will update the Image Processing Module A (IPMA) and the Power Steering Control Module (PSCM) to the latest available software level free of charge.
