## NHTSA's summary

Customer Satisfaction Program \- Due to the industry\-wide semiconductor shortage, the park assist feature is not functional on certain vehicles, built beginning December 2, 2021. The affected vehicle owners should have been made aware of the condition at sale, and notified, that once parts are available, they would be eligible for a no additional cost retrofit to enable the feature. Dealers are to replace the park assist control module and setup the serial data gateway module to restore the Park Assist feature. Some vehicles may also need additional modules to be reprogrammed.
