The oil on this car was changed at 8K, 16K, 26K, and at 36K. At the 36K oil change, it said due in 1 year/11,000 miles. This afternoon I turned the car on and it was suddenly 20 miles overdue - at 41K.

It didn't count down either (never said due in 1,000 miles), and the last time I checked around 39K, it said I had 8K left. It's been at least 80% highway miles too. It didn't get triggered by the date either - that still is way off in mid-2020.

I saw saw few other threads on weird intervals and they indicate usually that the car was reset to an originally short interval (doesn't seem like this case). I have to wonder why suddenly the interval dropped (looked like it was due at 47K, now at 41K), could it have been changed remotely? But other posts look like you have to go to a dealer to reprogram/reset systems and there aren't over the air updates. Either way, I'll be going to an independent shop, but the timing (after the 36K free interval ends) seems very suspicious
