Power Steering Pump problems of the 2008 Mitsubishi Lancer

All Mitsubishi Lancer evolution x from years 2008 through the cars final gear in 2015 suffer from a design flaw to the s-awc system. The active yaw control / active center differential system relies on a pump in order to operate . The location is unprotected from the elements and thousands of them have failed to date. . Mine failed which rendered my car to no longer drive in a predictable or safe manner. The all wheel drive and stability control system was compromised and traction control no longer functions as expected. Instead of this becoming a recall Mitsubishi extended a warranty to replace this exact component rather than admitting fault for an obvious design flaw. They refused to warranty mine as this exception was only made after my warranty had already expired even though my pump failed before I hit 100k miles. The acd / ayc pump is critical component to the safety and stability of the Lancer evolution 10 . Extending the warranty to only cover a small portion of failures is unacceptable and dishonest. The design is unsafe and the repair and replacement of this and other affected components is extremely costly. This should be a recall. All pumps will eventually fail as the seals eventually fail and corrosion of the pump or electric motor . This effects all evolution 10s regardless of climate. . Read more...

During cold weather (approximately 40 degrees or less) during the evening, my super all-wheel-control servicing light was triggered during a low speed turn. This indicates a faulty or failing awc/ayc pump, a mechanical component which provides ayc fluid to the front and rear differential of the vehicle, aiding in stability control. When the pump is inoperable, decreased (or no) pressure/fluid is sent to the differentials of the vehicle, which can cause serious drivetrain damage and failure-- thus the ayc pump is recognized by Mitsubishi as a critical component of the drive train. However, it is not covered under Mitsubishi's 5 year/60,000 mile drivetrain warranty, which I feel is disingenuous. This is a a serious safety concern as a faulty or failed pump effectively disables the awd component of the vehicle and makes the drive train more likely tosuffer catastrophic damage during use, which can result in crashes and injury. Mitsubishi is aware of this issue and that these pumps are poorly-designed for providing the ayc fluid to the differentials during cold weather; the fluid becomes extremely viscous at low temperatures and the pump is either unable to continue to flow the fluid to necessary components or the pump completely fails in the attempt, requiring expensive replacement at the owner's expense.
