NHTSA complaint #11766070

Owner complaint summary

While operating my 2022 Mitsubishi Outlander, a strong raw gasoline odor began entering the passenger compartment through the HVAC vents. The odor is present while driving but becomes significantly stronger when the vehicle is stopped and idling. After the engine is turned off, the gasoline odor gradually improves. The condition has occurred repeatedly. I am concerned about occupants being exposed to gasoline vapors inside the passenger compartment and the potential safety risk associated with fuel vapors being present during normal vehicle operation. I contacted a Mitsubishi dealership regarding the problem. The dealer advised that the only open recall currently showing for the vehicle is an unrelated software recall. The fuel odor has not yet been diagnosed or repaired by the dealer. Mitsubishi has issued Technical Service Bulletin TSB-25-17-001, “In-Cabin Fuel Smell When Vehicle Is Idling or Being Driven,” for 2022-2024 Outlanders. The bulletin describes fuel evaporation causing an in-cabin fuel odor associated with the location of the canister vent and provides a repair procedure involving the fuel filler tube assembly and vent location. There were no warning lights associated with the condition and no crash, fire, or injury. The vehicle is available for inspection.
