In your first post you said they were now feeling ok, after you trip to Heathrow. What's changed? I'd say either try a different make of tyre, see if you still notice this effect. I'd also say get the suspension geometry checked, not just an alignment but full 4 wheel check. Also have the rear suspension bushes checked. As to whether the garage would take back the tyres only a phone call will answer that.

The hybrid health check also looks at the cooling system, it's more than just the traction battery check. https://blog.lexus.co.uk/lexus-hybrid-health-check/

I have a Pixel 2 android phone and have connected services working. The only function not supported is email messages. Have you set up an account on the Lexus portal, this is required for things like the connected services to function. Live traffic, parking info etc..

I wonder how that would work should the unfortunate happen and such a modified car hits a pedestrian and causes the very head injuries this pop up feature is designed to mitigate? How would one's insurer view such a modification? Tampering with a safety device?

I had the same on my boot lid on the ceramic coated Sonic Red RC. Took it to the dealership and they arrange for the boot lid to be polished and recoated.

Quite fascinating and relatively simple compared to other LSDs. A bit like comparing an e-CVT with a conventional automatic? Fewer components, less wear potential. Worth reading the top comment by techdaemon in the section below the video..

I use one of these, quick, easy to read and accurate Amazon.co.uk

According to the Lexus EU tech doc for my 2016 RC300h the car maintains brake hydraulic pressure to all four wheels to prevent the car rolling backwards

According to my handbook - "The Pop Up Hood system cannot be reused once it has operated. Have it replaced by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer." "When the Pop Up Hood is operated ●Do not pull the hood lock release lever. Doing so after the Pop Up Hood has operated will further raise the hood and may cause an injury. Do not drive with the hood raised, as doing so may block the driver’s vision, possibly causing an accident. Do not forcibly push down the hood. As the popped up hood cannot be lowered by hand, doing so may deform the hood or cause an injury. If the Pop Up Hood has operated, have the vehicle inspected by any authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer. If the Pop Up Hood has operated, stop the vehicle in a safe place and contact authorized Lexus retailer or Lexus authorized repairer, or any reliable repairer."

Wife is threatening divorce if I clean it on day 3 of ownership! Storm clouds are gathering anyway, guess we'll have rain within the hour ..

We had it briefly a while back but then gone again! 

Answered above posts 2 and 3 ...

See your other thread...

Find a different fitter! They shouldn't be wiring into the traction battery circuit. There will be a 12v accessory fuse for this sort of thing.

I can't resist ... The RC300h is fast enough, more than fast enough to loose one's license There I've said it and I'm proud to be a 300h driver..

Another subtle change is the operation of the retractable steering wheel, now triggered by the seatbelt buckle fastening or releasing and not the Power button.

I noticed this on my 2016 RC especially after washing the car. It always cleared within an hour and didn't affect light output.

Just collected my new RC300h, now in Azure Blue, replacing my Sonic Red 2016 model. First impressions are, it's noticeably quieter. There is much less 'milk-float' whine on deceleration. The car will accelerate much longer on electric, the car switching to battery power more readily in general driving. The Mark Levinson sounds much fuller than the standard audio in the 2016 model, which wasn't poor in any respect. The Sat Nav has been improved no end, much easier to set routes etc.. Filled the tank with V-Power and looking forward to exploring the suspension and steering upgrades

Sorry, meant the antenna amplifier

No issues whatever regarding DAB reception across the south. I drive from east to west quite often and have never experienced drop-out. This is with my previous Merc and current RC. Suggest getting the antenna checked out along with the amplifier?

Answer #13 in this link explains it quite well, it's long but in the last half it talks about using neutral https://mechanics.stackexchange.com/questions/5739/use-of-neutral-gear-in-automatic-transmission This from my CLS handbook "Stopping When you stop briefly, e.g. at traffic lights: Leave the transmission in gear. Hold the vehicle with the brake. When you stop longer with the engine idling and/or on a hill: Set the parking brake. Move the gear selector lever to position P."

In non hybrid automatics putting the box into neutral will cause extra wear on the clutch and brake bands. Owner's handbook usually recommend keeping this in D unless stopped for prolonged periods, when one should shift into P.

No leaks at connector to the strut?

Tyres do take a short while to rid themselves of surface release agent and to settle properly on their rims. Always advisable to 'break' them in gently for the first 100 miles or so. Check ,as posted above, wheel bolts are tight. Check also the tyres are fitted the correct way round, if they are directional. What are the pressures like? But if, as you say, they now feel ok and the above checks are all ok, I would just take it easy for a few more miles.
