So my oil was changed and car serviced by the dealership (I know, I know) about 3 months ago. I've since put only 2k miles on the car. Sunday I popped the hood to do a routine check after a drive and noticed that the reservoir was completely empty.
The dealership towed the car in this morning and did a fill and pressure test and said they can't find a leak. No coolant in the oil, either. They are going to drive it a bit to see if that makes a difference. Otherwise, they don't know why.
I asked if they had any suggestions as to what may have happened to the fluid and he said no clue and nothing they could do about it.
Anyone here have any similar problems or suggestions? I hate to just take it back and drive it until it happens again. It didn't just magically disappear.
