Service bulletin SSM 54521

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2026 F-150 vehicles equipped with a 3.5L EcoBoost engine and 2025-2026 F-150 Raptor vehicles equipped with a 5.2L or 3.5L engine may exhibit a lack of power while in transport mode and up to 1 hour after exiting transport mode. This may be due to these vehicles having a feature to limit power and top speed in transport mode. This feature automatically disables after exiting transport mode, waiting 1 hour, then cycling the ignition status to key OFF for at least 10 seconds and then starting the vehicle. Top speed may be limited to as low as 40 mph (65 km/h) and maximum acceleration is reduced. This condition does not affect vehicle durability and no additional diagnostics or service is required for this condition. If this condition persists after exiting transport mode, waiting 1 hour and cycling the ignition, refer to the Workshop Manual for normal diagnostics.
