Some 2016-2018 Toyota Prius and 2017-2018 Prius Prime vehicles equipped with intelligent clearance sonar (ICS) may have improper software programming in the ICS system. The ICS system may improperly activate when the vehicle enters certain types of carwash facilities and is placed in Neutral.

If the ICS activates, the system will exhibit warnings and the system may apply the brakes. This applies to Prius vehicles produced from late November 2015 to late June 2018; and Prius Prime vehicles produced from early April 2016 to mid-July 2018. The affected vehicles require a reprogramming of the ICS system.
