An engine issue in Honda Pilots, Acura MDXs, and TLXs from the 2021 to 2025 model years could lead to stalling, a loss of power, and the risk of a crash. The problem may affect 17,000 vehicles in Canada and has caused Honda to issue a recall.
The concern stems from a programming error in the fuel injection electronic control unit (FI-ECU), according to the National Highway Traffic Safety Administration (NHTSA), America’s automotive safety regulator. The part helps metre the flow of fuel to the engine but its control logic was improperly set. Due to this production error, the FI-ECU could incorrectly detect a torque control failure, and the engine would stall as a result.
Upon investigation, Honda along with NHTSA determined that the root of the cause was a supplier-issued part. Due to the nature of the problem, it can be resolved by simply reprogramming the FI-ECU.
In total, more than 310,000 vehicles in North America are being recalled, including the 2022-2025 Acura MDX Type-S, 2023-2025 Honda Pilot, and 2021-2025 Acura TLX Type-S. All three vehicles are powered by the same 3.0L V6 engine.
Only around one per cent of recalled vehicles are expected to experience this issue. As of this writing, no injuries or collisions have been reported as a result of this problem.
Owners of the vehicles impacted will begin to be contacted by March 2025, and dealerships will fix the issue free of charge. For those that may be affected, additional information can be found on your vehicle on the Honda and Acura recall website.
