Summary

Some 2020 Mustang vehicles may exhibit a concern of the decklid not opening when it is attempted to be open when a valid key is within range of the vehicle. There may also be a concern where the horn gives a double chirp noise when locking the vehicle. This may be due to a fault with the body control module (BCM) software. Reprogram the BCM to correct this condition. Refer to Workshop Manual (WSM), Section 419-10. For claiming, use causal part 15604 and any applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

Owners of these vehicles have filed 26 complaints in the electrical category.
