I had a leak in a similar place in my 2008 Rx400h---the radiators and spigot pipes for the hoses are made of plastic. After many years and miles the plastic become brittle and hardened and the natural slight rocking of the engine on its mounts eventually causes a leak where the spigot pipes enter there radiator core and flex with the slight engine movement.. It's definitely a radiator out job and you may be able to plastic weld around the spigot pipe onto the radiator. My Lexus specialist advised me that would only be a relatively short term solution and it would be best to fit a new radiator. No problems since then. I am afraid that I have no idea why it should affect the hybrid system.

I had the rubber cover shown in your email perish on my 2008 Rx400h---although the catch was still working. I purchased the same one as shown. in your email. It was a bit fiddly to instal and I ended up using the original screws rather than the ones supplied. It was replaced because I was fearful of water ingress into the switch mechanism. All working fine.

There must be some parasitic drain on your battery for it to discharge so much. I have a 2007 Rx400h and it was still using the original factory fitted 12 volt battery until earlier this year when I had to replace it after 15 years of usage. Even before replacement I could quite happily leave it for four weeks whilst we were on holiday and it would start just fine upon our return.

Had a similar situation some years ago when my wife BMW 3 series estate was written off by a woman pulling out of their driveway without looking. The police were called as both drivers were admitted to hospital---thankfully with only very minor injuries. Their subsequent reportI apportioned the whole of the blame to the other driver. I then informed her insurance company that I wasn't interested in their money---I merely wanted a vehicle of similar specification, age and mileage. As the car was a fairly unique specification that was going to be difficult. I accompanied my response with letter from my BMW dealer explaining how difficult it would be to source a similar vehicle and that in his opinion it would cost at least $X thousand pounds. Other insurance company paid out a very generous amount in full within a week without any further quibbles. It might be worth approaching your Lexus dealer to ask if they would provide a similar letter saying, in their opinion, how much it would cost to replace your written off car.

Not totally reliable----I had to replace the original 12 volt battery in my Rx400h after fifteen years of use. But then I suppose Lexus don't actually meake the batteries so they are excused

I had a similar problem on my 15 year old Rx400h---purchased a can of the strangely named Gummi-pflege from Amazon. https://www.amazon.co.uk/Liqui-Moly-7182-Rubber-Care-75-ml/dp/B00CSYM1K8/ref=sr_1_1_sspa?keywords=gummi-pflege&qid=1693569258&sr=8-1-spons&sp_csd=d2lkZ2V0TmFtZT1zcF9hdGY&psc=1 The rubber seals around the rear hatch seemed a bit "sticky"--not surprising after such a long time. Treated the seals and hey presto, the rear hatch was working smoothly again. I think that perhaps the "stickiness" of the seals was preventing the motor from lifting the hatch.

I purchased the vehicle in July 2010 and it currently has 116,000 mies on the clock. Nothing ever spent on the car other than "consumables" Although I was horrified last year to find that the original 12 volt battery---which was fourteen years---old had finally expired !!

My Rx400H is now fifteen and a half years old with a perfect MOT record. Not even one advisory, let alone a fail. Just had it serviced by my Lexus Independent Specialist who tells me that it is fine for another year and he can see no reason why it won't pass next years MOT

The magnetic part of the phone mount is the part attached to the air vent in the car. The only thing that is attached to the phone is a small disc of steel stuck onto the back of the phone. This does not affect the NFC capability of the phone in any way.

I use the magnetic one suggested above. Perfect, the phone doesn't fall off, nor does the mount. Thoroughly recommended

Remove glass and disconnect the wire that controls the dimming

Wouldn't a higher pressure result in less rolling resistance and therefore a lower fuel consumption?

I would beware of squirting oil or other liquid lubricants into the lock. Much better to use Graphite Powder . Cheap and will last you for years https://www.amazon.co.uk/Kasp-K30050-Graphite-Powder/dp/B00BTOBHH6/ref=sr_1_5?crid=19HPJR8R3KV3P&keywords=graphite%2Blubricant%2Bfor%2Blocks&qid=1638182460&sprefix=graphite%2Blubricant%2Caps%2C159&sr=8-5&th=1
