Freezing screen washer jets

[Baggers]

My brand new ES300h Takumi still with the original Lexus screenwash in the tank suffered from freezing washer jets. So I added washer fluid (ready mixed and good for -10 degrees) to see if that resolved the problem but it didn’t. Screen de-icer spray did resolve the problem temporarily but a few miles later the jets froze up again. The outside temperature was only -1 degrees. Has anyone else had this problem and are there any solutions out there?

Sadly, I reported this to lexus when I picked up mine back in 2021. Looks like they haven't bothered to tell their dealers or whoever does the fill to not be stingy morons. Get rid of what is in the tank completely, then fill with proper winter screen wash. After that you'll be fine.

Hi Peniole, yes I think you are right. So I half emptied the tank and refilled with Prestone Extreme screenwash. It’s a bit more expensive than the usual supermarket tat but 90 miles in freezing temperatures and no sign of the jets freezing up so it is worth the extra cost. Recommended.

I actually find this thread interesting because I got a very good deal on summer screenwash and stocked up thinking it's all the same but the jets didn't work and was told by a friend to try winter screenwash. Can't comment if any better because all the shops I went to this evening had none in stock.

You could try amazon, they have it. I bought mine in Tesco where it appears to be a standard line. Glad my question helped both of us!

Incidentally, I do think that a car of this quality should have a heated washer bottle and heated jets to avoid this problem. Never in the last thirty years have I experienced this and I’ve had BMW, Saab, Volvo, Vauxhall and Honda - all with heated jets. I really like my new Lexus, it’s brilliantly equipped with every extra, so I am very surprised that they overlooked this basic piece of safety equipment.

+1. I have had to divert the conversation in the office when my scheissewagen owning colleagues have started discussing the heated washer jets on their misguided purchases.

I’m guessing one of the problems here is the extreme thermal efficiency of the engine, which doesn’t heat up the surrounding area in the engine bay as much as an old diesel. I have noticed on journeys that the bonnet can still be frosty even after driving for an hour

Indeed - and this is a good thing - but all the more reason to fit heated jets and water bottle one would have thought.

Having just come from Lexus Glasgow, to replace a dead 12v Battery on my 450h+, the screen wash nozzles have frozen.

2c and my new ux300e not the same car I’m aware but also frozen with supplied Lexus screen wash that did seem a little watery. 
 

hybrids and ev especially should have heated washer jets at the minimum like my trusty Subaru I keep as backup. Going to heat them later today and get out as much of the old crap screen wash and fill with Prestone see if it helps. I think it’s also a placement issue as well though as back screen and headlights do not freeze. Are the jets open to the air
