STRUCTURE:BODY:HATCHBACK/LIFTGATE:SUPPORT DEVICE/STRUT
Mitsubishi Motors North America, Inc. (MMNA) is recalling certain 2018-2022 Outlander PHEV and 2014-2020 Outlander vehicles sold and/or currently registered in Alaska, Connecticut, Delaware, District of Columbia, Illinois, Indiana, Iowa, Kansas, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, North Dakota, Nebraska, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island, South Dakota, Utah, Vermont, West Virginia, and Wisconsin. The liftgate gas spring cylinders may corrode and lose pressure, which can result in a gas spring cylinder rupture or the liftgate falling unexpectedly.
A gas spring cylinder rupture or a liftgate falling unexpectedly can increase the risk of injury.
MMNA will replace the left and right liftgate gas springs, free of charge. Owner notification letters were mailed October 6, 2025. Owners may contact MMNA customer service at 1-888-648-7820. MMNA's number for this recall is SR-25-002
SEAT BELTS: REAR/OTHER:BUCKLE ASSEMBLY
Mitsubishi Motors North America, Inc. (MMNA) is recalling certain 2014-2019 Outlander and 2018-2019 Outlander PHEV vehicles. The second-row center seat belt buckle may interfere with the right-side seat belt buckle when the seat backs are folded down. The interference may cause the right-side seat belt buckle cover to come off, making the buckle latch inoperable and unable to restrain an occupant.
An unrestrained occupant has an increased risk of injury in the event of a crash.
MMNA will notify owners, and dealers will modify the second-row center seat belt buckle cover, install a new warning label to the second-row seat support base, and provide a new warning label insert for the owner's manual, free of charge. The recall began September 1, 2020. Owners may contact MMNA customer service at 1-888-648-7820. Mitsubishi's number for this recall is SR-20-004.
ELECTRICAL SYSTEM:SOFTWARE
Mitsubishi Motors North America (MMNA) is recalling certain 2018 Mitsubishi Outlander PHEV, Outlander Sport, 2018-2019 Eclipse Cross, and 2017-2018 Outlander vehicles equipped with a Forward Collision Mitigation (FCM) system that detects pedestrians. Due to incorrect software, the FCM-ECU (Electronic Control Unit) may apply braking for longer than needed, even after a pedestrian is no longer detected.
If the FCM-ECU software activates the brake for longer than necessary, the driver may react by applying additional braking. The resulting rapid deceleration of the vehicle can increase the risk of a rear-end collision.
MMNA will notify owners, and dealers will reprogram the FCM-ECU software with updated software, free of charge. The recall is began October 16, 2018. Owners may contact MMNA customer service at 1-888-648-7820. MMNA's number for this recall is SR-18-007.
FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
Mitsubishi Motors North America, Inc. (MMNA) is recalling certain 2018 Mitsubishi Outlander Sport vehicles equipped with a Forward Collision Mitigation (FCM) system and 2018 Mitsubishi Outlander PHEV and Eclipse Cross vehicles and 2017-2018 Outlander vehicles equipped with an Adaptive Cruise Control (ACC) system and/or an Electric Parking Brake (EPB) system. The software for the Hydraulic Unit Electronic Control Unit (ECU) may be incorrect, possibly preventing the intervention of a safety system such as automatic emergency braking, Anti-lock Braking (ABS), Electronic Stability Control (ESC), or the Brake Auto Hold (BAH) function when any of these systems are in use.
If the safety systems do not function as intended, it can increase the risk of a crash.
MMNA will notify owners, and dealers will update the Hydraulic Unit-ECU software, free of charge. The recall began October 16, 2018. Owners may contact MMNA customer service at 1-888-648-7820. MMNA's number for this recall is SR-18-008.
EQUIPMENT:OTHER:LABELS
Mitsubishi Motors North America, Inc. (MMNA) is recalling certain 2018-2019 Mitsubishi Outlander vehicles equipped with 18-inch alloy wheels. The Certification Label lists an incorrect rear wheel rim size. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 110, "Tire Selection and Rims."
The incorrect rim size information on the label can cause the operator to replace the rim with an incorrect rim size, increasing the risk of a crash.
MMNA will notify owners and send them a corrected certification label, free of charge. Owners can also choose to have the label replaced by a dealer, free of charge.
