I think it should be pointed out that, for some of the issues listed, the number of posts about those issues can be somewhat misleading. For at least a couple of the problem threads, the same 4 or 5 people have posted repeatedly, and they have said essentially the same things over and over again. I suspect that, if you examined those threads carefully, you would find that the number of different people who have posted and the number of posts that have added new information would be only a relatively small fraction of the total number of posts in those threads.

On my RX, it barely heats up. At -20C, it will take forever to warm up!

Yeah I took it to the dealer. Initially, they said one tire had uneven wear and that is causing the issue. After changing the tires( I changed all 4) the issue is still there and they are now insisting that this is normal. In short, I am finding it hard to convince them now since they do not want to accept the issue.
Could you please advice if this is causing due to tires or wheels only ? And nothing can go wrong with suspension? What is the best way to diagnose it?

Okay I will elaborate the issue again. I have Rx350 2016 model. After 20k km; the car started having some kind of vibration. The vibration was felt on the seat and not on steering wheel.
Lexus dealer identified there is one tire with uneven wear and suggested to replace. I got all tires replaced. The new tires are of same brand dunlop sports maxx 050 as the OEM. However the vibration is still there.
the vibration is felt at all speeds starting from 60 km / hr. I got the wheel balancing and alignment done. Road force is also okay.
The dealer is not able to identify the issue now and trying to convince me that its normal. Although I know its not normal .
would appreciate experts suggestions here.

All wheels are checked by Lexus dealer as well as a separate tire shop.
No it does not affect when brake is applied. It only vibrates when car is moving.
and its neither speed specific. Starts around 60 km / hr and continues..

I’m not an expert, but it’s starting to sound like it could be in the transmission. I’m basing that on things that rotate & don’t effect steering or braking. Is there any time when it’s much worse?

I updated the first post - looks like with today's TSB Lexus has now addressed the top three issues to some extent.

I think overall the RX is probably a well put together vehicle and their sales certainly aren't hurting. In fact you can go on the forum for just about any vehicle and find horror stories. usually many more than the Lexus forum.
Of course more vehicles sold, the more stories likely to appear.
Now with that said, I definitely got a Friday afternoon special, with more issues than I have ever had from any other vehicle including 2 previous IS's. The dealer has been good trying to resolve them, but I'm now approaching 30K miles and more issues.
Here's the quick summary. 1. Air conditioning gurgle - Fixed under a TSB but now the air is weak and still gurgles. 2. Passenger seat replacement as it whistled like a tea kettle 3. Both rear door seals replaced after they simply fell off on a hot day. 4. Right rear door seal replaced a 2nd time after it fell off again on a frosty day. 5. Transmission remap under a TSB - still lunges around at low speeds, perhaps an 80% improvement. 6. Rear suspension trailing arms replaced 7. Trunk sounds like creaky floorboards when closing on a warn day and can be heard across the parking lot - unresolved 8. Rear suspension acting up again after 3k miles of the trailing arms being replaced. 9. Rattles from so many places I gave up trying to locate them.
On the plus side, it has incredibly comfortable seats. Although when the warranty is up it's probably getting traded for something else.
