The ayc pump failed by displaying a blinking tarmac light. It constantly flashes while driving. The ayc pump correlates with the steering and stability control for the rear differential. This is a big hazard. The ayc pump should be relocated to the trunk compartment so it is not exposed to weather conditions like snow and rain. This will protect the ayc pump from failing. The warranty will not cover this failed pump at all.

Monday 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.
