Manufacturer summary

Original wording in English

Some 2020 Mustang GT500 vehicles built on or before 28-Aug-2020 may exhibit various concerns with the active exhaust system. These may include "Drive Mode Not Available" or "Exhaust Mode Not Available" messages, and/or diagnostic trouble codes (DTCs) P26C5, P26C6, P26FE, P2BF9, P2BFB, P26C7, P2BF5, P2BF8, P2BFD, and/or P2BFA. This may be due to pinched wiring or a misaligned bracket where the exhaust actuator mounts. To correct the condition, follow the Service Procedure to make sure that the exhaust is seated correctly.

Repeated filings are grouped only when make, bulletin number, publication date and complete summary agree. Original record numbers are retained. Older publications remain available, and an explicit later version is shown when established. Pre-1994 vehicle associations are separated from default results; an unspecified year does not mean all model years apply.
