One of the last times my car was broken. The machine engine needed serviced, I took my car there, the light was on. The one that says the engine needs serviced. They rebuilt the transmission when I got back my car, the transmission was rebuilt and safe, the light was off. I assume it was because the car was fixed. After awhile a couple of months later I took it to another and she found out the bad engine light wires were cut. This mechanic told me for some reason my car leaks some and the engine goes on again because the wire is cut.
