There are 1 owner-reported speed control & cruise complaints for the 2014 Mitsubishi Outlander Sportin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
In February of 2025 I was driving on the highway and my car stopped accelerating and the “ASC system required” light turned on. The RPM stayed at 4,000-5,000 and my car dropped from 60MPH to 20MPH. I had to drive on the side of the highway 20 minutes home like this. I took the car into a shop and they said the exhaust and catalytic converter was clogged and replaced it. It ran okay after that for about 3 weeks and then the same thing started to happen again. I have had to pull onto the side of the highway about 10-15 times as of writing this to restart my car/drive home going 20-30MPH. I brought it to the Mitsubishi dealership last week and they said I will need a whole new exhaust manifold, muffler, and catalytic converter due to it “being clogged” and quoted me just over 6,000 for it to be fixed even though I just replaced all of this in February. They did not give me an explanation as to why this is happening or explaining what is causing the “ASC system service required” light to go off.
