Most Common Mitsubishi Lancer Evolution X Faults & Repair Costs
AYC Pump Corrosion and Failure
The Active Yaw Control pump is mounted in a vulnerable position and corrodes badly on UK cars, bringing warning lights and expensive drivetrain-control faults.
AYC or ASC warning lights, Drive mode faults, Pump noise or no response from the system
SST Twin-Clutch Judder or Failure
SST cars are very sensitive to correct fluid and calibration; neglected boxes can judder, skip gears or fail outright with huge repair bills.
Jerky pull-away, Refusal to select gears, Transmission warning or limp mode
Rear Subframe and Underbody Corrosion
Even specialist-owned Evo Xs can rust underneath in the UK, particularly around the rear subframe and suspension pick-up points.
