There are 2 owner-reported electrical system complaints for the 2009 Mitsubishi Outlanderin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
The MMCS system has a known bug. As of October 2023 the date and time of the system has defaulted back to 2004. The defect has disabled features such as maintenance records that are logged since new. The defect has been reported to the dealer and they have acknowledged there is currently no fix. The dealer also noted that replacing the GPS receiver does not correct the problem and it is likely a head unit firmware issue. There are hundreds of complaints via Internet forums that Mitsubishi equipped MMCS models from approximately 2007 through 2014 are affected. The only way to retrieve any data in the system is to disconnect the GPS receiver and manually input the current date. That fix disables the navigation system in lieu of having all the data the system has stored since new which could be a safety issue for some owners. This is an unacceptable problem for most owners.
