Subaru broke down
I have a 2018 Subaru (78k miles) that I’m driving cross-country from Oregon to Pittsburgh. I just had an oil change 1,750 miles ago and a pre-trip inspection — everything was clear.
Today I got a red oil pressure warning light. I pulled over immediately both times it came on. I checked the dipstick on a flat surface and oil is full, clean, and at MAX level. No oil on the ground, no leaks visible.
First time the light came on was after parking on a slight angle for 10 minutes — went away after restarting. Second time came on while driving on flat highway.
When parked and revving the engine, it has a noticeable misfire (missing under acceleration).
Currently being towed to a Subaru dealer in Lincoln, Nebraska.
My questions:
1. Could a faulty oil pressure sensor explain both the warning and misfire together?
2. Could a bad spark plug cause a misfire that triggers oil pressure fluctuation?
3. What diagnostic tests should the mechanic run?
4. What’s the worst case given I stopped driving immediately each time?”
