I put a bottle of injector cleaner in the tank and make sure I only use Top Tier gas and within a couple of tanks the Service Engine Soon light with the "Increased Emissions" warning goes out. That's not to say that there isn't really an underlying cause in your case.

There area number of other intermittent problems I have had with this car. The latest was the SOS Malfunction warning. That went away over night. Same with the 'mute' function stuck in 'mute' mode. I think there was one other but I don't recall what it was. It seems the car has the ability to "heal itself" if left to go to sleep.
Hey bro here,s a trick for the mute button lag,,, member boramkiv hooked me up with,,,,,

Push and hold all three until the screen goes blank. It will reboot and all should be good to go.
