Differential Unit Problems of Mitsubishi Lancer
Mitsubishi Lancer owners have reported 4 problems related to differential unit (under the power train category).
#1 - Differential Unit problem of the 2008 Mitsubishi Lancer
The car is a 2008 Mitsubishi Lancer evolution. This vehicle is equipped with an active control differential (acd) which is actuated by the acd hydraulic pump. The acd is a part of the vehicle's all wheel drive system. After giving the engine an 8 minute warm up on idle, the vehicle was being driven on a 20âºf of ambient temperature. The vehicle was on a stop light, and upon gently accelerating the car on green light a warning light came up on the vehicle's dash board. The vehicle was brought to the nearest Mitsubishi service shop 4 days after the incident with the warning light still on the vehicle's dash board. After service technician worked on the vehicle, the service manager said that the acd pump is the problem which needs to be replaced and will cost $2100 of parts and labor. 8 months prior to the incident, the Mitsubishi service shop re-flashed my vehicle's all wheel drive ecu to specifically prevent the failure of the pump especially in cold environments. Mitsubishi replaced the acd pump at my expense, and it's been approximately 2 years that my vehicle is on the replacement pump. The service manager told me that the combination of the hydraulic fluid becoming thick on cold weather and the corrosion on the hydraulic pump that the salted winter roads bring is what makes the acd pump fail. After researching on the internet car forums, this occurrence where the acd pump fails on colder regions is not uncommon even with the previous generations of this vehicle that are equipped with this acd system. It was 12/19/11 when this differential unit issue happened.

#2 - Differential Unit problem of the 2010 Mitsubishi Lancer
The vehicle having this issue was a 2010 Mitsubishi Lancer evolution. 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. It was Saturday, August 10, 2013 when this differential unit issue occurred.

#3 - Differential Unit problem of the 2003 Mitsubishi Lancer
The vehicle's vehicle identification number (VIN) was JA3AH86F73_. I have a 2003 Mitsubishi Lancer evolution. At 19,000 miles the car developed a very loud sound coming from the front of the car at speeds above 30mph. I work at a auto repair shop and concluded that the sound is coming from the transfer ase/front differential. More than likely from ring gear being improperly shimmed from the factory. If the problem is not resolved with the transfercase/front differential, when the problem occurs with other Lancer evolution owners there is a chance that the transfercase/differential could lock up causing a accident or cause more damage to other parts of the drivetrain. This differential unit problem happened on Wed., Oct. 27, 2004.

#4 - Differential Unit problem of the 2003 Mitsubishi Lancer
The car involved was a 2003 Mitsubishi Lancer evolution. 1) I am in the military deployed to afghanistan. . . 1 month before I deployed my stock clutch was slipping. This is not covered by Mitsubishi's warranty. I was reading on my forums and there were at least 2 to 300 people experiencing the same problem all around 5000 miles on the car regardless of how the car was driven. I purchased a new clutch, $1300 and had the dealership install it for $800 figuring that they would warranty there work. I deployed to afghanistan, came back and about 2 months of driving the car my car was making a hi squealing noise. The problem was diagnosed as the clutch. Although they did no other inspection. I ordered a new clutch had them install it. . . Same problem continued. So I paid another 700 for a new clutch for no reason. Then they rediagnosed the problem as the rear differential. They replaced that under warranty. . . Problem was fixed. I was babying the car for a week or so because of the clutch break in period is suggested 1000 miles. While doing 60 mph on the highway the car noise came back just as bad as before. . . Called Mitsubishi and they refused repair by order of the district rep. 2. The noise has progressively gotten worse and has caused my car to be sluggish now. I would like my drivetrain to have a thorough inspection and fixed where necessary. I would also like to be reimbursed for my clutch that I had to buy that wasn't faulty to begin with. I also think Mitsubishi needs to adhere to a warranty on there drivetrain. Regardless if you install an aftermarket clutch in your car, the drivetrain should be covered. Who in there right mind would pay for the installation of a new stock clutch and fly wheel if its just going to go bad at the same time you need your oil change. This issue happened on 10/15/04.
