Bad injector caused cylinder failure or valvr constant valve tick. Blown spark plugs caused piston meltdown causing for the pistong rod to shoot throught the block cause a fire to the engine.. Luckly I stop the fire took it to a delaership to verify the cause of the damage but the technicinas told me that theres nothing they could do because the battery die there for it reset the computer module erasing all the data with the probable cause and nothing was done after that.. Bought a new engine and now after 20,000 miles I get the same issue but mitsubishi dose not wanna be resposible for a replace engine to which they replace.

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.

Transfer case in this car omits a loud whining noise when driving forward. Noise increases in volume the faster the car is going. This whine is due to the wearing of the gears because of a faulty design. When the transfer case whine happens, it has a high probability of locking up which will cause all wheels to stop spinning potentially causing a serious accident and possibly death.

While driving normally the message "4wd system require service" came up. I bought the car used 40k miles and now it only has 43k miles. I have driven mildly since I bought it and have never abused the car. I heard it's caused by ayc acd pump failure, acd c161e.

Acd c161e was read in the ecu. It's ayc acd pump failure. I didn't drive hard. I drove normally which I usually do. And 4wd service required comes on. I searched a lot about the issue. Mitsubishi should have a recall about this its a common problem for evo I read.

Active yaw control pump that is part of the car's all wheel control system is failing. Pump is not covered by manufacturer power train warranty even though it's part of the power train. Due to location of the pump, it gets sprayed with water on the road. This caused the pump to fail prematurely due to corrosion.

The acd / ayc pump failed. Can be dangerous to lose awd system. Not covered under warranty.

While driving the vehicle in warmer weather, a warning (4wd system service required) is displayed on the dash and the s-awc awd system is disabled. The active center differential and torque biasing rear differential are disabled, which greatly reduces handling and causes the vehicle to react differently than normal in emergency situations. This is the result of a failing acd/ayc hydraulic pump. Mitsubishi will not cover these pumps under the power train warranty, even though it is a very common problem. The pumps corrode internally and are unable to build and maintain pressure.

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.
