What's wrong?
The fuel injection electronic control unit, or FI-ECU, is the computer that controls how much fuel enters the engine and how that fuel is matched with incoming air. On the 2021-2025 Mdx Type S, Tlx Type S, and Pilot, that control program is part of the engine management system that keeps torque delivery steady while the vehicle is being driven.
In affected vehicles, the supplier's settings for the air-flow and fuel-injection correction logic were wrong. Under certain driving conditions, the FI-ECU detects a torque control failure even though the engine is being asked to run normally. That software error can stall the engine or cause a loss of power.
There is no warning sign before failure. An owner can be driving normally and then experience an engine stall or sudden power loss without an earlier dashboard message or drivability symptom listed in the recall filing.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific vehicle.
What's the safety risk?
An engine stall or loss of power can leave the driver with less control and increases the risk of a crash or injury. If your VIN is included, schedule the software repair soon and avoid ignoring stalling, hesitation, or sudden power loss. Repair is free at any franchised Acura dealer.
What should I do?
- Check your VIN to confirm your 2021-2025 Mdx Type S, Tlx Type S, or Pilot is included in this recall.
- Contact your nearest franchised Acura dealer to schedule the free FI-ECU software update that fixes the engine stall or loss-of-power risk.
- Bring the recall notice if Honda has mailed one. If not, reference recall number 25V031 when you call.
- Drive cautiously until the software update is complete, and pull over safely if the engine stalls or loses power.
What happens at the repair
At the dealer, an Acura technician reprograms the FI-ECU software that controls fuel injection. The software update and labor are covered under the recall, so the repair is free. Honda used its standard reimbursement plan for this campaign. If you paid out of pocket for a related FI-ECU software repair before the recall notice, bring documentation to the service desk or contact Honda customer service to start a claim.
