general problems of the 2011 Mitsubishi Lancer

Vehicle operating at >3000 rpm cvt and engine whine and loss of power.

Tc-sst revs up in reverse and in first before take off.

Acd/ayc pump has completely stop working in my vehicle. I took my vehicle to be service and the person who was doing the service on my car told me that the acd/ayc pump has gone out and I need a replacement. I found that weird, because I have not driven my car for roughly about a month and for an issue to pop up was very weird. After doing research, I seems that multiple people have the same issue were these pumps go out unexpected. There are only 1400-1600 of these cars made year in the states and to see many people have this problem in the u. S. And around the world mind boggling to many of us. Mitsubishi needs to find another solution or remedy to this issue. Since I live in the south, my local dealership is not wanting to cover this and I travel along the east coast with my car.

4wd system service required light came on with less than 40000 miles, this was caused by a malfunctioning acd pump. Pump is located behind the rear right side tire and is exposed to elements. Car was in new york state for 4 years and driven on snow/salted roads. Pump has corroded. This is a known problem with the ralliarts and evolutions. Dealership refuses to cover under the power train warranty, they say this is a luxury item and also becuase there were modifications made to the car. The modifications made have no impact on the corrosion of the pump.

The issue first presented itself as a flashing all wheel control indicator light at approximately 35,000 miles while on the highway. It was initially an intermittent issue that occurred only occasionally. I arrived home from my trip and was at the dealership at 36,200 miles. Their scanner indicated a c161e code which indicates an acd pump actuator lock. The dealership stated this can happen under aggressive driving conditions and was normal. However, after informing them the issue occurred while cruising on the highway and also when stopped at a light they informed me to return if the issue persisted. I returned a week later after I confirmed the issue occurred every time I drove the vehicle, but they were unable to read codes because their diagnostic tool had broken. At 37,000 miles the vehicle displayed a message indicating I needed to service the all wheel drive system. The nearby dealership's scanner was still broken. At 37,900 miles I arrived at a different dealership and they found the codes c161e and c161f which indicates an acd pump failure. During the time since the issue first began I also noticed the traction control didn't appear to function. In wet conditions when I lost traction I did not see the dash indicator for traction loss / traction control nor did I feel the system kick in to compensate. I believe this presents a potential safety issue. This appears to be a common and well documented issue, especially in areas of varying climate. The root cause in my scenario is most likely volatile local weather where winters involve heavily salted roads and temperatures that range from warm to below freezing in the same day. This can lead to premature pump failure due to a known issue with a pump seal and rust.

Acd pump failed and dealership wouldn't cover it car was still under warranty!!.

My car began to have a flashing active yaw control light on the instrument panel. It was determined that ayc/acd pump was failing due to severe corrosion. When this happens, the awd stops functioning, so the car is now in two wheel drive mode. Mitsubishi mounted the ayc pump in the rear fenderwell area where it is openly exposed to the winter elements such as snow, salt and sand. This is a very well known problem and the dealer I went to has done about 6 cars in the last month or so just for this problem. The car was taken to a local Mitsubishi dealer for warranty repair. The dealer was very helpful and was going to replace the pump under warranty, but when was denied the request due to the fact that the engine had had a "tune" on it. So, the pump will have to be repaired at cost to myself. The reason I am bringing this to your attention is because this is a very apparent design flaw. Placing a critical part like this pump openly exposed to snow, salt and sand thrown up by the tires which in turn corrodes the pump, is a safety hazard. This stops the awd to function and renders the car to be only driven in two wheeled drive mode when the car is in fact, designed for all wheel drive. There are so many well documented cases of this problem, at some point in time, Mitsubishi will have to acknowledge this and do something to mitigate the severe corrosion of the ayc pump.

At slow speeds when your foot off the accelerator or holding it steady and you apply the pedal down to go forward there is a delay as if the transmissions trying to find a speed to go to. My mechanic checked out the engine all computers systems are good and the engine runs fine he is linking it to the transmission being a cvt and possibly a defective or bad design. This long delay has resulted in causing an accident because I would try to accelerate and the car would stall out for that amount of time the engine that's not the problem it's the transmission.
