so, it's REALLY interesting that I just found this thread!
On Saturday, my "check engine" light came on (not my oil pressure light..let me forewarn you, I have been blessed with one of the 2015 CX5's that have electrical issues every now and then like the shifting cable being bad, and various sensors, so thanks TSB's!). I, in turn, checked my oil because that's all I know to do at this point.
Dipstick reads fine, dirty because I'm over since the pandemic, but still, it's fine, and I continue out to my boyfriends house. There's no leaks beneath my car (I park in the same spot), no smell of burning oil, nothing. I'm on my way home on Monday after driving about 60 miles with my check engine light on and I notice that the RPMs are really high..like 5000/6000. For expressway driving and not passing, that's a LOT. Then, the "Low Oil Pressure - continued driving may result in engine damage" light flickers on, and I panicked, because I'm in the middle of nowhere. The car starts to sputter (the light isn't on still, it's only flickered), and I find a turn off to turn my car off at. Now the car won't start.. and NOW I have the "Low Oil Pressure" light on the side of the road and the engine is trying to cool. Boyfriend brings 4qts of oil to put in, because I check the dipstick and it's bone dry now. I wait a few minutes.. and now it says that I am above the oil limit by 2 qts.
Currently, the car was towed to a place that I didn't want it to be at (thanks AAA), and the mechanic there doesn't believe that the TSB's on my vehicle might have anything to do with my electric marvel of a vehicle ("Ma'am, I'm a mechanic, not an electrician") and believes that I have blown my engine (at 144k) and should just scrap it.
*sigh Thanks for the info and thanks for listening to me ramble
