I suspect that my 2013 XJ either has a cracked washer fluid reservoir, bad hose, or loose hose connection. The low washer fluid warning light on the right side of the instrument panel lights up about a day or 2 after I have repeatedly refilled the reservoir even though I have not used the washers.

Anyone else have this happen?

I'll let the dealer fix it since my car is still under warranty. Out of curiosity, does anyone know how to troubleshoot this to determine exactly where it is leaking from? Can't see much from on top of the engine.

I haven't had this happen on my 2011 XJL, but it seems to me your suspected causes might explain this phenomenon. The view around the XJ engine compartment is very restricted to say the least. You fill the washer fluid in the blue capped reservoir, and after that one can see nothing. Good luck and report back your dealers findings!

 

I had a similar problem on my XF.
It turned out that one of the headlight washer hoses had become unclipped from the headlight.
You can just see the end of the disconnected hose if you look real hard down the back of the headlight, dunno about an XJ though.
Difficult but not impossible to reconnect without removing any parts, but you need small and nimble hands, again that's for an XF, dunno about an XJ.

 

I know this is a very late follow up. The reason for the loss of washer fluid was a cracked plastic reservoir. It was replaced under warranty 5 years ago and I haven't had a problem since then.

 

Hi Stuart,

I know it was 5 years ago but will you be able to recall whereabouts the leak on the floor? I am getting the same warning light and I could find water on the floor right in front of my right front wheel.

 

That's the same as mine. Odds are that your windshield washer fluid plastic reservoir is cracked, just like mine.

 

Thanks Stuart!
But my mechanic said the reservoir is fine, maybe he did not check thoroughly.
This plastic milk bottle is not cheap though

 

If not the reservoir, then the headlamp washer is usually the culprit, esP; if your leak is in front of the wheel.

You can get your hand on the inner washer arm via the engine compartment if you don't have too thick arms/hands (position your other hand, on the outside of the washer, it's then easier to find .
You can also insert a phone and take some pictures/videos/
Usually you'll feel/see humidity and/or quite some dry deposits on the inner arm.

BR,

Thierry
