The vehicle has exhibited recurring ignition-system and powertrain malfunctions involving repeated ignition-coil failures, engine misfires, and catalyst-system efficiency faults. These issues cause intermittent loss of power, hesitation during acceleration, and unstable engine performance. The malfunction has occurred multiple times since the date of purchase and has been confirmed through diagnostic trouble codes related to misfire events and catalyst-system operation. A certified Mitsubishi dealership confirmed that the failure pattern aligns with an active manufacturer recall and corresponding Technical Service Bulletin affecting the same model year, engine type (4B11), and vehicle platform. I was informed that the vehicle “falls under” the same defect pattern listed in the current recall/TSB; however, because the vehicle no longer has an active factory warranty, the dealership stated they would have to sell the repair parts rather than process the issue under recall or warranty coverage. Despite this, the same safety-related symptoms described in the recall and TSB continue to occur. The defect presents a safety hazard because the vehicle may lose power or fail to accelerate when entering traffic, merging, or navigating intersections. Warning indicators have appeared repeatedly, including the check engine light and catalyst-system warnings. The problem has been reproduced and confirmed by authorized service personnel on multiple occasions. All components and diagnostic documentation are available for inspection upon request.
