In February of 2025 I was driving on the highway and my car stopped accelerating and the aœASC system requireda 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 aœbeing cloggeda 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 aœASC system service requireda light to go off.
