So...

I checked the oil life monitor a few days ago and it was at 49% or so. Checked tonight and it was 99%. I know that I didn't reset it. The only thing I've done to the car was disconnect the CAGS connector and reconnect it. That's the only thing that has happened to the car and I'm certain I didn't hit the reset button on the oil life screen...

Any thoughts?

Also, I've noticed that the Nav volume seems to change on its own. I have to go and reset it periodically. Anyone else have either of these issues? Any thoughts on possible resolutions or fixes?

sounds like something in the PCM... The Engine oil life is stored in the PCM not in the radio. I dont know how that could have reset unless you flashed the PCM or manually reset it (by holding down the reset button)....

Very weird....

I definitely didn't do either... Perhaps I need to schedule a trip to the dealer...
