Mystery chimes and warning on 2011 MKZ Hybrid

Recommended Posts

Hi there,

I am hoping for some technical help on my 2011 MKZ Hybrid. I bought it certified used 9 months ago and had the first oil change (at Lincoln) last week. Coinciding with the oil change has been the arrival of warmer weather here (80+ degrees some days). I am getting very infrequent mystery chimes from the instrument panel. Here is what is happening:

 

4 chimes - ding dong, ding dong

1 out of 5 times a red message flashes (literally a split second) over the temperature gauge. Most of the time I just get chimes but nothing else. Just ding dong, ding dong out of no where. However I did catch the message one - "High Engine Temperature".

Most of the time it happens during a slow turn but sometimes happens while driving straight.

Sometimes I get the chimes shortly after starting the car

 

If it is temperature related, I did read something about air bubbles in the coolant. I'll keep exploring that route.

 

Any other thoughts?

 

Thanks!

I took video of the issue. The volume is a bit low so turn up your speakers. Hopefully this works:

 

And Lincoln can't get me in for another 2 weeks so hopefully we find out what the issue is.

The issue ended up being related to a loose wiring harness just like expresspotato thought.  If I remember correctly, it was a wiring harness on the transmission.  I remember the tech saying the wires were loose in the plug and had to be re-soldered.
