Looks like we’ve got a few offers from forum members, to take a look at a failed unit, to see if they can diagnose or get to the bottom of it. Who wants to send their broken unit to either @ColinBarber, @toffee_pie or @steve2006?

That’s a big claim and a scandal, if true. Do you have a source for this? Really doesn’t put Lexus in a good light if so…

Thought provoking topic. Has changed my view on things, that’s for sure. Tints incoming!

Tinted windows (legal ones)? Any take on that being a mod?

Watch out if you’re building up two lots of no claims. If you don’t apply those to your car after I believe two years, you lose them entirely!

Looks like an old toilet seat hinge 🤣

A great outcome. Do you know what part needed changing? £300+ is a lot when you got the lot done for £110!

Go for it @Dells! You should start and lead the compilation effort. It’d be a great thing to have.

Don’t take their word for it and check it yourself.

Mine is the same and has been since I got it 7 years ago.

The eBay link in your first post shows £429.99? I’d buy new at that price! The link in your first post also has a broken bracket. I replaced a light myself last year and can’t remember the importance of this bracket. It may be the bracket is of utmost importance and you’ll have trouble fitting it in a broken state. Mine is an F-Sport and I used the headlight from Lexus Parts Direct. There was no F-Sport specific headlight.

With those two expensive items needing a fix, and someone having driven into you, it sounds like an insurance claim would be worthwhile.

The best fixes are the easy ones like this!

I question how often a battery needs disconnecting in the workshop. For some repairs, yes, but a general service, I don’t think it’d be part of the procedures. There are supposedly ~25,000 Is300h in the UK. How many that are vulnerable to this problem, and undergo a repair that requires a battery disconnect at a dealer, is probably a small number.

It has indeed rained! I will certainly be doing the clean at some point.

And today I wake up and use the window. And the problem has vanished… 🤷‍♂️

I wonder if a 12v source connected to the terminal in the bonnet (for jump starting) would suffice then?

Is there a procedure which one can follow before disconnecting and/or reconnecting the 12v battery, to avoid the dreaded black screen or dead unit?

Thanks. That’s got to be the best place to start. A good clean up. Though this does sound like a mechanical grinding. But worth a shot anyway.

Hi all Another issue for me. Car is coming up to ten years old (Sept 2013) and is immaculate for its age. However, it’s getting expensive to do these fixes. I’m one who has opted not to go down the dealer route and therefore have their warranty. Firstly, a new headlight needed last September. Then a new front bumper parking sensor failed. Air con is smelly at the moment. And now a grinding noise on the window. First two I sorted myself. Air con, TBC. This one, not sure. Noise only occurs when winding window down, for the last three quarters (first quarter somewhat normal). Winding window up, no noise. Was happy in taking the door apart myself to have a look but annoyingly, it needs a 12v battery disconnect. I am afraid of this due to other posts in the forum. I’m almost certain there’s nothing in there but happy to have a look. Reading about, it seems it could be the plastic parts in the motor giving up the ghost. No idea if that’s true. Going by what I saw at the below link, and a few others I can no longer find. Anyone else experienced this? I’ve not seen it posted here before. Search yields nothing. Any pointers appreciated.

Could be! Video attached above. Sounds like engine bay, a fan that comes on and off constantly. Maybe it’s OK. I've encountered a new issue (separate to the air con) today now however, will post later if I can.

Attached in the forum. Seems the upload service I used will delete it after 25 hours. I guess it’s a fan not a compressor. Fan on for 14 secs. Off for 5. Back on for 14. Off for 5. 474FA168-C2F9-45FE-BF88-C91FD15D6086.mov

Promised video. Thanks for any advice! Video Upload

Thank you! Any more info and symptoms of this please? I have no OBD errors. But it may not show there. If this is the case, what’s damaged, what needs fixing, and how significant/expensive is that job?
