I started my car and the awc service light came on. I came to a controlled stop, and restarted the car per the instructions in the vehicle manual. Upon restart, the same service light came on. After the dealer ran a diagnostic, it was found that the high pressure pump for the active stability control system had failed. I was told that this part was not part of the drive train and would not be covered under warranty. The day the pump failed it was very cold and there was packed snow on the roadways. If I was driving at higher speeds and this pump had failed, I believe the automobile would not have behaved as expected with the awc stability active.
2008 Mitsubishi Lancer Evolution driver assistance complaints
Page 2 of 2: complaints 11 to 19 of 19, newest first, as owners wrote them.
This is report of a known failure by mitsubishi motor corp. At 50,800 miles on 12/17/2013 my cars super-active center differential (s-acd) started blinking at me. It would not allow changing of the settings anymore for tarmac/gravel/snow. Immediately there after, the driver information panel popped up with a yellow "awd service required" indicator. I brought my car to nashua, nh mitsubishi/hyundai for diagnosis on 12/19/2013. There they applied tsb-sc11-002. This unfortunately did not resolve the issue. I was then informed that the car required a replacement acd pump and was quoted $1,995 for the repair, which confused me due to the fact that my car was still under manufacturers power train warranty, and a pump, that controls the awd system of a car, seems to be power train related, at least in my eyes. The north east regional representative was contacted on my behalf by the dealership to request coverage of this item, which was ultimately denied. This is a severe safety issue, as the car no long handles properly in conditions it was designed for. I am no longer able to select the car for snow, living in the north east, driving a car marketed in the north east, this is a huge problem. To further the issue, this problem is well known by mitsubishi, it has been documented well, tracing all the way back to cars manufactured in 2006. 90% of all pump failures could be completely eliminated by adding a seal to stop corrosion inside the pump which leads to the untimely failures. If no recall is issued for this failure, at the very least, mitsubishi motors should be forced to cover this under power train warranty for 5yrs/60k miles. Instead of limiting it to 3yrs/36k bumper to bumper. Link to documented cases - http://forums.evolutionm.net/evo-x-general/655162-those-you-acd-pump-failures-merged.html.
Because of the location (rear wheel well) and design of mitsubishi's active center differential pump, they are prone to failure. Several factors aid in the galvanized corrosion of the pump's internal plate, some of which include temperature fluctuation and weather. Vehicles that are in service throughout the snow belt states in the us and well into canada seem to be the most affected. My vehicle was just outside of the vehicle warranty range for time but very well inside the range for mileage.
Started my car 1n 30 degree weather and let it idle for a couple minutes pulled out on my street where I live and my acd/ayc quit working I had a picture of all for wheels on my info center with the front wheel on an angle . Took it to the dealer and they said my all wheel drive pump was bad and that since my car is an evo it was not covered.I paid to have it fixed and got my car back and my timing chain broke dealer said it was not covered also since it was an evo 3500.00 in 1 month.
The s-awc or super all wheel control system on the mitsubishi lancer evolution helps the all wheel drive to actually work. I had a service message pop up on my car with the s-awc system being indicated. After reviewing the car's manual and the internet to help diagnose the issue of why it was causing it, I'm told there is an ever-increasing number of vehicles with this s-awc pump failure either in super cold conditions or very hot conditions. This has the potential to be very dangerous if the pump ends up going out when someone is making a turn or is relying on the all-wheel drive to actually work in adverse conditions. The only notable change is a difference in steering feel and the service message popping up after several minutes of driving, though due to safety reasons, I am trying not to push the car too hard until the problem is addressed.
The car is displaying an s-awc service light, it has yet to be diagnosed by the dealership but I have brought it in previously for the same issue. Looking online there is a whole mass of forums stating that at 40,000+ miles the ayc pump breaks. This seems rather suspect given so many individuals are experiencing the same problem within the same time span. Mitsubishi has been reportedly turning down warranty coverage for this under their power-train warranty, while I am unsure if they will do the same for me, the issue is seemingly prevalent enough that they should know about it.
On monday 2013 april 22 I [xxx] (owner of vehicle) was getting off my shift at approximately 0700 hours from bethel twp pd; where I work as a patrolman. The temperature was fairly mild 60-65f, I started my 2008 mitsubishi evolution 10 to let it warm up like I always have for approximately ten minutes. I put my evo in gear and on the center l.e.d. Screen I received the c161 message which indicates s-awc failure or super all wheel control. This effects everything with the cars' suspension stability, yaw control, and the "smart breaking" feature. For an un-experienced driver this could be catastrophic. Knowing the importance of this I was forced to bring the car to springfield mitsubishi in springfield, pa. 1(484)574-8434. Now I'm stuck with a $2132.00 bill and the car is still in the lot because I don't have the $2132.00 to "shell" out. I went to two separate forums www.evoxforums.com and www.evolutionm.net, and I don't know whats scarier the thousands that have this problem and are told by their local dealer its safe to operate in that condition or the fact that no body is doing anything to assist or fix the problem. Please be the ones who make the difference here..... Thank you [xxx] ps I apologize I am writing you again, I never received any response the first time.......

Saturday morning I warmed up my car for 5 minutes. Started to drive my car for about 15 seconds, awd service required popped up on my display. I stopped the car and brought it back home. Looked up what the issue could be and found out that the acd pump has failed. This is a well known problem from mitsubishi for these cars and they have not issued a recall or real fix. Without the acd pump functioning, there is a possibility that the car can lose traction in certain situations or damage the entire drivetrain system. Mitsubishi claims that its not part of the drivetrain so there is no warranty and it's also a "luxury" system. Controlling wheel traction is not a luxury its a safety feature.
Mitsubishi motors of america has a awd ecu software update for vehicles specifically driven in cold conditions. Dealerships and mitsubishi corporate have denied my claim to obtain this software because my car was sold in california and they have said it is not eligible. I take my vehicle every year up in the sierra nevada mountain range where temperature conditions are similar to any of the northern states within the service bulletin. The mitsubishi service bulletin number is sc-09-002 also available here on google docs to read ( http://docs.google.com/fileview?id=0bznigp9lgbk8ntu5otrinjgtztjhmc00mjy0lwi2nmmtowzhzju1nzfkndcz&hl=en) it states that "this reprogramming procedure will modify the all-wheel-control (awc) ecu software to accurately match the operations check of the ayc/acd motor with current ambient conditions. Extremely cold weather causes increased excessive load on the motor, which could result in damage to the motor. This bulletin describes procedures to reprogram the awc ecu with new software parameters to prevent this condition." the safety concern is that if I'm using my awd vehicle in cold conditions and the critical awd components fail due to driving in cold conditions as stated in the service bulletin and cause me to have an accident or even hurting others which can be prevented with a 20 minute software update that is available now.
