Thanks guys, will check out the horizontal rubber tonight and if cleaning it doesn't help I'll get some silicone spray. So I reckon replacing any rubbers isn't the solution? Or is silicon spray a 3 month solution and replacing the rubbers maybe 2+ years?

This made me laugh! Maybe you're right though. Well that doesn't sound promising. Is it a really loud squeaky noise as well in yours? I'll try and look up your post and also email my dealer.

I own a Lexus IS 300h 2013 since 6 months now and since it has gotten colder over here (The Netherlands) I notice the driver side window make an awful squeaky noise when opening it. I know it's most likely just one of the rubbers alongside the outside of the window frame, but even after a couple of car washes and trying to find if there's a place where some dirt might've gathered (which isn't the case) it still does this. Since I'm still 9000 km from my next maintenance, I'm wondering what to do and if this might be a common issue or just normal after 160.000 km? Is something like this worth going to the dealership for or is better (cost wise) to just sit it out until the next maintenance is planned? Which will be at least 6 months from now with my mileage. On the one hand I don't mind that much since it's just a noise and only when opening the window, closing not so much. But every now and then when I enter a car park and open the window people passing by look at me and I can't help but think they might look at me as if I'm a cheapskate, buying a hybrid luxury vehicle but not maintaining it properly. What do you guys think?

I own an IS 300h 2013 model for exactly 6 months now and my average is now 5.87 l/100km (or 17.0 km/l). I'll stick to the metric numbers since I know there US and UK gallon which need to be taken into account when converting into MPG. I have to admit that in the first 2-3 months I was only getting 6.2 l/100km (16.1 km/l) on average, even though that was the summer period. I'm currently on summer tyres as well (will not be changing for maybe a week of snow here in The Netherlands) and my last refuelling came in at 5.84 l/100km while it was constantly between 0 and 8 C outside. I measures using the Spritmonitor app, so this is the actual mileage, the dashboard info seems to be off by at least 0.5 l/100km (it shows 5.3 l/100km when it actually is 5.8 for example). Note that I said during the first 2-3 months I had a worse mileage, I come from a Lexus CT 200h 2012 (drove it for a year until I had to replace it) and a Prius II 2006 before that. What I notice is the different driving style approach you need to have with the heavier IS compared to the CT or Prius, which are almost equal. Both the CT and Prius you could drive calmly and get about 4.5-5 l/100km (20-22 km/l) or absolutely trash it and drive 180 km/h on the Autobahn and still get at least 5.5 l/100km (18 km/l) at worst, even in the winter. I bet this is largely due to their ICE of only 100 hp compared to the 181 hp of the IS. I also notice that while the IS has a much stronger electric motor that is being used even at 120 kph and therefore contributes to being able to run those high speeds and still only 1300 rpm or something. However, my strategy when I wanted to drive calmly and save some fuel in the CT or Prius doesn't work in the IS at all! In the CT/Prius I would use Eco mode and only put my foot down until the eco meter was exactly where the power area started. When I do that with the IS, it seems to use the ICE a lot and keep it between 2000-3000 rpm, but since it takes so long (relatively) to reach the necessary speed, it seems to use a lot more fuel. I spoke about this with the Lexus dealer and they advised me to reach the given speed as quickly as possible, but not so quick that you're giving full throttle, I tend to keep the needle of the eco meter about halfway in the power area. After I reach 50/80/100/120 kph I can let go and the ICE immediately goes down in rpm. This has made it more efficient in the last 3-4 months compared to the beginning. And while it's not a huge amount more efficient, it's enough to drive like this, especially since it's actually faster and less annoying to those Audi's behind you. ;-) I know I could gain more by braking more slowly (more regen and saving the actual brakes as an added bonus) and I've recently started using the EV mode as much as possible as advised by some Lexus dealer video on YouTube. During my normal commute I know when I get home, take the exit on the highway and enter the neighbourhood there's a little less than 2 km to go on 30 and 50 roads (kph). I now do that completely using the EV mode, even at 2 C outside it's not an issue. In the morning that means the battery is almost empty, but since the whole system needs to warm up anyway, most of the lost energy from heating up goes to the battery pack and when I arrive at the highway again, the battery is full enough (2/3) to quickly enter it without having to rely on the ICE alone.
