Ford Maverick · 2022–2024
Hybrid powertrain control software given to some Mavericks in service can set a false park-motor position sensor code and force the truck into neutral while driving; it coasts, shifts itself to Park at a stop, and then runs in a limp mode up to 30 mph. The loss of motive power increases the risk of a crash. It affects 2022–2024 Ford Maverick Hybrid (2.5L FHEV) trucks that received the affected HPCM software (Ford recall 24S33). Recall 25V133 (Ford 25S16) covers 2022–2024 Mavericks whose 24S33 software was not installed correctly but was recorded as done.
Common Symptoms
- Truck drops into neutral and coasts while driving
- Shifts itself to Park at a stop
- Limp mode limited to 30 mph
- Flashing "Drive" indicator
- "Neutral" shown on the instrument cluster
- Wrench warning light
- Warning messages and a chime
How to Fix
Have a Ford or Lincoln dealer update the HPCM software under recall 24S33 (NHTSA 24V330), free of charge. If the truck is also listed under 25S16 (NHTSA 25V133), the dealer reinstalls the software and validates the software part numbers before closing the recall. Ford lists a flashing "Drive" indicator, "Neutral" on the cluster, a wrench light, warning messages and a chime as the warning signs.
