Ford Maverick · 2022–2024
On affected 2022-2024 Maverick Hybrid trucks, a recent update to the Hybrid Powertrain Control Module (HPCM) software calibration may result in a forced neutral condition while driving, causing the vehicle to coast to a stop and automatically shift to Park, along with a wrench light, multiple warning messages, and an audible chime. After shifting back into Drive the vehicle enters a limp home mode with limited torque at speeds up to 30 mph. Ford's powertrain controls team determined that new Hybrid Transmission Internal Park Module (HTIPM) software released for use in service in January 2024 can result in DTCs U1010 and U1011 shortly after installation, and Ford was aware of 315 warranty claims in North America as of April 15, 2024. The recall covers approximately 8,727 vehicles (Maverick population ~8,369).
Common Symptoms
- Vehicle suddenly shifts to Neutral while driving
- Auto-shifts to Park as truck coasts to a stop
- Wrench warning light illuminated
- Audible chime and multiple IPC warning messages
- Limp home mode limited to ~30 mph after restart
- Truck strands driver and may require tow
How to Fix
Dealers will reflash the HPCM/PCM with corrected software free of charge under recall 24S33. If the remedy software for Safety Recall 24S33 was not installed correctly during a prior dealership visit, the underlying forced-neutral condition may still exist, so verify the calibration ID on the OASIS report — a follow-up recall (25V133 / 25S16) was issued in April 2025 for incorrect reflashes, and a further expansion was issued with owner notification letters mailed February 12, 2026. Primary confirmed DTCs in Ford's Part 573 report are U1010 and U1011; owners have additionally reported U1028, U0418, U0401, and U0131 on basic OBD readers, all of which should clear after the corrected update. Repair is performed at no cost and takes less than one hour.

Frequently asked questions
What does U0418 mean?
U0418 stands for "Invalid Data Received From Brake System Control Module 'A'." This network code means a control module received data from the Brake System Control Module (typically the ABS/electronic stability module) that failed its validity or plausibility checks. The modules in your car constantly exchange information over a communication bus, and the receiving module decided the brake module's messages were corrupt, out of range, or implausible. Because it touches the ABS and stability control system, this can disable those safety features, so it should be diagnosed promptly.
What are the most common causes of U0418?
The most common causes of U0418 are: Low or unstable battery/system voltage (common on stop-start vehicles), Faulty ABS / brake control module or its software needing an update, Corroded or loose connector at the brake module harness, Damaged CAN bus wiring (chafed, pinched, or shorted high/low pair), Poor or high-resistance ground at the module, Water intrusion or corrosion in connectors, Module reprogramming or configuration error. The specific cause varies by vehicle.
How much does it cost to fix U0418?
Repair costs vary widely depending on the root cause and vehicle.
