Problem overview

Some Mitsubishi Mirage G4 owners report experiencing surging on hills accompanied by a loud metal noise, which may be indicative of issues with the Continuously Variable Transmission (CVT) system. These owners have noted that receiving a CVT trouble code suggests a specific transmission problem that requires prompt diagnosis and resolution. Additionally, problems with belt-driven accessories or the belts themselves could contribute to the unusual noises and surging behavior. It is recommended that owners seek a professional inspection of the CVT system, including a thorough examination of the bearings in the alternator, idler, and tensioner pulleys. Depending on the findings, repairs or replacements may be necessary to address the CVT trouble code and related symptoms. Prompt attention to these issues is crucial to prevent further damage to the vehicle's transmission and ensure safe driving conditions.
