Three months ago I had a collant leak that required my radiator to be replaced. Just days ago I got a VTM-4 light, a VSA! light and an engine light. I pull over right away and noticed my oil temp gauge was at Hot. As I came to a stop I got a battery and oil light. I shut the engine off and lifted the hood. I towed it into a mechanic and the next day they said it was fine and a clamp came loose, leaking all the coolant. I started the car and it vibrated abnormally but I decided to monitor it. The next morning I get high vibes and a blinking engine light on my way out. Towed it to the same mechanic and was later told I had a P0305 cylinder 5 misfire. After a long look they say I now need a new engine. SMH... How in the world does this happen? I have 190k kilometres on the engine. Someone please shed some light for me.
