Strange engine whining noise

Recommended Posts

Hi. We have a 2014 MKZ Hybrid that has started making a whining noise when the gas engine is running. It only makes the sound when the engine engages and it does it in park and all gears. It's a lot less audible in neutral and reverse though. It gets louder with acceleration as well. I've never heard anything like this before. It resembles alternator whine, but I'm finding out that these cars don't have alternators. The sound is coming from right under the electric motor, but it's so tight right there I can't really see what's there. I made some videos of the sound to hopefully help diagnose it. It's driving us nuts and we really don't want to take it to the dealer. Has anyone heard anything like this on their hybrids (or even gas models) before?




Thanks in advance for any input.
Ed

Sounds expensive.

Did you ever find out what it was

Sounds somewhat like the noise the trans makes when the bearings fail on the transfer shaft, though I can't tell without being there in person. There is a TSB for it, and hybrid specific components are covered by a 8 year 100,000 mile warranty.
