Mitsubishi Outlander Fuel Pump Failure

On 2022-02-03 10:44:08

Mitsubishi Motors Corporation (MMC) will be asking the owners of certain 2022 Outlander SUVs to return to their dealerships to correct a problem affecting the fuel system in their vehicles.


In June 2021, MMC received 5 field reports in the US, with complaints that the engine in their 2022 Outlander didn’t start or the engine stalled while driving. MMC began an investigation as they continued to monitor and received additional field reports from the US market. An inspection of parts recovered showed that the commutator and brushes in the fuel pump were abnormally worn which resulted in an inoperative fuel pump. Further investigation indicated that abnormal wear on the commutator may have occurred from an inappropriate manufacturing process utilized by specific operators.


Continued investigating and returned parts confirmed the abnormal wear on the commutator was due to an inappropriate manufacturing process utilized by the supplier. MMC concluded that all fuel pumps with the commutator produced before July 2021 could possibly be affected by the problem. In January 2022, MMC determined that a field action was necessary for the US to address this condition and decided to conduct a safety recall. MMC is not aware of any accidents or injuries related to this condition.


According to the defect report, an inappropriate manufacturing process at the supplier resulted in the commutator and wires in the fuel pump not fused correctly during production. The problem could result in poor continuity and abnormal wear in the commutator and brushes in the fuel pump. The fuel pump could become inoperative causing the engine to stall while driving or cannot be started. If a vehicle stalls while driving and cannot be restarted, the chances of an accident are increased.


Owners with defective vehicles will be asked to return to their dealers to have the fuel pump replaced. Mitsubishi Motors Corporation's number for this recall is SR-22-001 and the NHTSA campaign number is 22V-027.
