My Mirage's "service engine soon' dash light came on randomly, and for the first time last week. I took my Mirage into the dealer today, since my car is still under warranty. Turns out there was some corrosion on the fuel filler neck. So that was cleaned.. and they applied silicone to the surface.
This service was covered 100% by Mitsubishi free and without me asking. So, that's good the warranty works now.
I had some bad luck/issues with my local Mitsu dealer earlier this year re: faulty engine starter. * Took them 2 hours today to service the car since they were backed up apparently, but I got 2 free cookies.
The staff changes at my local dealer so much. Maybe that's normal in the auto industry
*I never raised my voice or swore, but I threatened legal action and that got the ball rolling
