Power Steering Pump Problems of Mitsubishi Lancer

All Mitsubishi Lancer evolution x models are having problems with the ayc acd pumps, this affects the stability and the handling of the vehicle specially in bad weather conditions because the system doesn't work properly in case of a slippery or bad road. The problem with this pumps begin with it's location because it receives dirt,water, snow and other elements that harm the pump. This should have a recall from Mitsubishi because it failed due to a bad design and location of it and it can cause serious problems for drivers specially in bad weather conditions, I will like this concern could be taken in consideration for all of us that are Mitsubishi Lancer evolution owners, thanks.

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...

I stopped at a light, the when I went to make a left turn my dash began to flash a "service required" light at me. After doing some investigation, it turns out that it is an extremely well known and unaddressed issue with the car's acd pump failing. It's a design flaw that costs thousands of dollars to fix, but failure of the part is practically guaranteed. Why there's no recall yet is completely ridiculous.

Started up one day and went to drive it and the all wheel drive pump had failed, caused a significant change in the handling of the vehicle.

On-dash warning light of "4wd system service required" came on. This warning is indicative of a active center differential (acd) pump failure, generally due to corrosion from treated winter road surfaces and/or the inability to handle cold-weather climates. Car was previously serviced under a technical service bulletin (TSB) to delay activation of the acd pump for this exact reason 2 years prior to failure. Mitsubishi has yet to correct this manufacturing defect and is currently refusing to honor warranty service of failed pumps under their 5-year / 36,000-mile powertrain warranty, stating that the pump is not required for the vehicle to operate safely and properly. In contrast, a working acd pump directly effects the vehicle's handling, traction & steering - and all 3 driving parameters immediately behave differently when the pump shuts down in self-protection mode or has failed completely. This vehicle has a driver-selected setting for tarmac (pavement), gravel/rain & snow conditions - these settings are completely disabled when the acd pump has failed, or is failing (on-dash warning with pump in self-protection mode). This issue effects several models (lancer, Lancer evolution, ralliart, etc. ) from model year 2008 to 2014, and hundreds of instances of this issue have been documented in online forums (and probably several-fold that amount that haven't been discussed online). Please look into this issue immediately, thank you.

Bought my vehicle as a certified pre-owned vehicle with 37,213 miles on it. At 43,000 miles, vehicle began having malfunctions with the all wheel control system and electronic stability control hydraulic pump. This should be an item covered under the 5 year/60,000 mile warranty, however, Mitsubishi states that it is not covered, even though it is part of the power-train, and required to work for vehicle stability and safety. Mitsubishi has continued to refuse to warranty the pump. This is not an isolated issue, and there have been dozens, maybe hundreds of other cars with the exact same malfunction, many of these were turned away by Mitsubishi even while they were under the power-train warranty.

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.
