I'm trying to diagnose whether the noises from my 4xe are "normal". My other EV and PHEV are absolutely silent when parked in EV mode when the HVAC is off; but my 4xe makes this consistent whine. I think it's the power steering pump. Curious if this is normal or something I need to take in to get looked at (dealer is not close, so don't want to take it in if I don't need to).
Can someone else try the following:
1) Ensure jeep has been sitting at normal temp (between 65-75 degrees) to ensure battery heater/cooler isn't activated.
2) Turn on jeep, put it in EV mode, then turn HVAC off, lights off, radio off, roll down windows.
3) Put jeep into reverse and then forward, confirm the pedestrian alert system activates. Then back into park.
4) Do you hear anything whining? Try turning the wheel, you'll hear the power steering pump spin up, and then after releasing the wheel, you should hear the power steering pump spin down - does it go all the way off or do you still hear it running? Mine still makes a whining noise, not sure why. On my hybrid power meeting on the uconnect it also shows a battery drain of 1KW. Where is that power going?
5) Turn vehicle off, sound will disappear and then you'll hear a few clicks.
Video enclosed. Is this "normal" for the 4xe - i'd say it's NOT normal for EVs in general.
