Hi,

There is one mechanic at my dealer who's being trained especially for the 4xe. He told me that there are two ways to bleed the air from the cooling system. Manually, with a under-5-psi-very-delicate-procedure-or-you-screw-everything-up, and the automatic one, done by activating the bleeding sequence through the board that needs to be replaced with the recall.

Fyi.

Hi all - thank you to everyone for all the posts. I've put ~290 miles on my Jeep and recently heard the sound of running water under the back seat after highway driving on electric only. Coolant levels under the hood look fine. No CEL but most of my miles have been low speed local driving. I'm assuming it's just that air in the cooling system needs to be bled.

I'm nervous to drive the car a long distance given all the stories until the dealer takes a look. But given there is no CEL I'm also nervous the dealer will just give me back the car (my local dealer is pretty terrible).

Do you know if there is a DIY way for the consumer to trigger the bleeding sequence? (sounds like the under-5-psi-very-delicate-procedure would not be consumer friendly)

The battery coolant and car coolant are different systems.
Take it back to the dealer and tell them to bleed the battery coolant several times.

Took it to the dealer... and as expected they claim they can't replicate the issue so did nothing. I've asked again if they can at least bleed the lines. Only other alternative is to wait until a CEL light comes on.

But maybe they are right and the running water sound is not going to cause severe issues. Who knows...
