Ok, I've been having what seems to be a strange problem with the add coolant buzzer. The buzzer has never went off when the engine was cold, or when driving. The coolant is very full, and does not need topped off.

The problem comes when I have driven the car up to operating temperature or more, and shut it off. When I come back in the car to leave, the buzzer goes off (this is perhaps 30 minutes after I shut the car down, that I'm restarting it). I immediately turned the car off, checked the coolant level, and seeing no problem started it back up. There was NO buzzer this second time starting the car up. This has happened twice in the past two weeks, just curious as to whether this is an early warning to something.

Thanks,
Steve

One more try...Haven't seen any coolant leaks, coolant is full at filler neck.

Any ideas? I hope it's just something that isn't important, but I would like to make sure.

I wonder if you have air traped in the system causing the buzzer to go off?
