Mitsubishi Outlander Sport transmission service light on with erratic mileage gauge and intermittent performance issues on Mitsubishi Outlander Sport

Some Mitsubishi Outlander Sport owners report experiencing issues when the transmission service light is on, along with erratic mileage gauge readings and intermittent performance problems. These issues may be linked to low battery voltage, which can trigger the transmission service light and lead to erratic performance. Additionally, some owners find that transmission fluid contamination, such as with refrigerant, can negatively impact transmission functionality and activate warning lights. A low transmission fluid level is another concern, potentially causing erratic shifting and strange noises while also triggering the check engine light. To prevent further damage, it is advised that owners avoid driving the vehicle until a professional inspection can be performed. If the vehicle is still under warranty, Mitsubishi's 10-year/100,000-mile coverage may apply to transmission repairs, making it worthwhile to check for warranty service eligibility.
