On the 2011-2026 Mitsubishi Outlander Sport, the Outlander Sport CVT develops a judder during low-speed acceleration and deceleration. The transmission hesitates when pulling away from stops, and the simulated shift points feel rough and inconsistent.
Replace the CVT fluid with Mitsubishi DiaQueen CVTF-J4 every 30,000 miles. A TCM reprogram may smooth out the shift calibration. Avoid towing with the CVT-equipped models.
On the 2011-2020 Mitsubishi Outlander Sport, the AC compressor in the Outlander Sport frequently fails between 50,000 and 80,000 miles. The compressor clutch bearing seizes or the internal reed valves break, contaminating the AC system with metal debris.
Replace the AC compressor, receiver/drier, and expansion valve. Flush the entire system to remove metal particles. Install an inline filter on the liquid line to protect the new compressor from residual debris.
