What is the 2014-2022 Mitsubishi Outlander Tailgate Gas Spring Cylinder Corrodes Internally and Can Rupture or Drop the Liftgate (Recalls 25V507 / 26V252)?
The steel cylinder of each tailgate gas spring is protected only by a heat-shrink resin sleeve. Salt water works its way under the spring's dust cap, sits against the bare cylinder wall and corrodes it. Because the cylinder holds high-pressure gas, a corroded wall can either lose… Repairs typically run $0-$400. Severity: high.
What is the 2007-2020 Mitsubishi Outlander 6B31 3.0L V6 Uses a Timing BELT, Not a Chain — Missed Interval Destroys Later Interference Engines?
A recurring and expensive owner mistake on V6 Outlanders: buyers and even some independent shops assume a modern V6 has a timing chain, so the belt never gets changed. The 6B31 3.0L V6 fitted to the Outlander runs a rubber timing belt with a service interval around 105,000 miles. Repairs typically run $700-$5,000. Severity: high.
What is the 2017-2018 Mitsubishi Outlander Hydraulic Unit ECU Software Defect Can Disable ABS, Stability Control and Automatic Emergency Braking (Recall 18V621)?
Mitsubishi recalled 2017-2018 Outlander models built with Adaptive Cruise Control (ACC) and/or the Electric Parking Brake (EPB) system because the Hydraulic Unit Electronic Control Unit (ECU) may have been loaded with incorrect software. On an affected Outlander, that faulty ECU… Severity: high.
What is the 2017-2018 Mitsubishi Outlander Forward Collision Mitigation Software Holds Brakes Too Long (Recall 18V620000)?
Mitsubishi recalled 2017-2018 Outlander models built with the pedestrian-detecting Forward Collision Mitigation (FCM) system because of incorrect software in the FCM electronic control unit (ECU). On affected Outlanders, the FCM-ECU can keep applying the brakes for longer than th… Severity: high.
What is the 2007-2020 Mitsubishi Outlander CVT Transmission Premature Failure?
The Jatco CVT in the Outlander is prone to premature failure, particularly under heavy loads and in hot climates. The CVT belt and pulleys wear prematurely, leading to slipping, shuddering, and eventual complete transmission failure, often between 60,000 and 100,000 miles. Repairs typically run $3,000-$7,000. Severity: high.
What is the 2014-2022 Mitsubishi Outlander PHEV Regenerative Brake System (RBS) Fault Drops the Car into Limp Mode Mid-Descent?
The PHEV blends friction braking with motor regeneration through the RBS control unit, which cross-checks wheel speed sensors, the brake stroke sensor and the motor controllers. If any of those inputs disagrees — most commonly a failing rear wheel speed sensor, but also a draggin… Repairs typically run $150-$3,000. Severity: high.
What is the 2015-2017 Mitsubishi Outlander Defective Engine Control / Power Supply Relay Causes Stall, Power Loss or Overheating (Recall 17V609 / SR-17-005)?
A relay supplier used an improper maintenance procedure on its welding machine, so internal welds inside several relays used in the Outlander's engine-bay relay box were made incorrectly and can lose proper electrical conduction. Depending on which relay is affected, the result d… Repairs typically run $0-$250. Severity: high.
What is the 2014-2021 Mitsubishi Outlander PHEV Quick-Charge (CHAdeMO) Contactor Welds Shut — DC Fast Charging Fails with P101C?
The PHEV isolates its CHAdeMO fast-charge port from the traction pack with quick-charge contactors. An abnormal-current event during a DC fast charge session — a station that drops or spikes current, or a handshake that aborts mid-session — can weld the negative quick-charge cont… Repairs typically run $150-$2,500. Severity: medium.
What is the 2014-2021 Mitsubishi Outlander Blocked Sunroof Drain Tubes Flood the Headliner, A-Pillar and Front Footwells?
The panoramic/power sunroof tray is not sealed — it is designed to catch water and route it out through four drain hoses, two down the A-pillars and two down the rear quarter panels. The front hoses exit behind the front inner fender liners, where road spray packs them with grit,… Repairs typically run $0-$600. Severity: medium.
What is the 2007-2020 Mitsubishi Outlander AC Compressor Failure?
The AC compressor in the Outlander is prone to premature failure, with the internal clutch bearing seizing or the compressor developing internal leaks. Failure typically occurs between 60,000 and 90,000 miles, leaving the vehicle without air conditioning. Repairs typically run $600-$1,500. Severity: medium.
What is the 2014-2026 Mitsubishi Outlander Front Suspension Clunking and Noise?
The Outlander develops front suspension clunking and knocking noises over bumps and rough roads. Worn front stabilizer bar end links and strut mount bearings are the primary culprits, with noise appearing as early as 30,000 miles. Repairs typically run $200-$600. Severity: low.
