I posted info on 26 February that should help you. Hopefully, having gone through the steps you've already taken, it won't be too bigger step to do the reset. Good luck.

So I did the full reset and finally things seem to be talking again. I had to do a couple of re-registrations with the app before the car finally started greeting me by name again, not requiring me to accept the terms each time and remembering preferences for driver assist and the meter layout. It seems that things like radio presets didn't get automatically restored and there is a gap in journeys shown in the app between applying the software update and finally getting communications restored. Also a couple of journeys today haven't shown up yet (the last 2 are there, but 2 before that are missing, several others today are then there).

Hopefully all will be well now but do keep an eye on the communication icon. I found that I had to reconnect every trip until I did the reset. I didn't find it necessary to press the power button as you describe. 

If you do need to go down the reset route, your journey data may not appear straight away. It did for me but it took a few days before it reliably appeared for a friend.

Yes unfortunately on next power cycle it has disconnected again, redid the steps but next power cycle back to the grey icon, so the reset it is going to have to be ...

So I finally got around to trying the steps to turn the data link back on. I was about to follow the instructions above but the very first screen I came to under "Info & Security" had several options including "Activate all data" which was off. Selecting this to "on" brought up the "blue screen of agreement" after which the communication icon was now no longer greyed out. There was a warning about not all services being available that might require pressing the power button (presumed to mean infotainment power) for 3 seconds - so far I've not done this. I also needed to select "Use voice data" to on again which presumably explains why when I've tried to use "Hey Lexus" it has been continually saying it couldn't understand me; the agreement screen again appeared. With these selected I noticed traffic information was back on the map which had also been missing.

So far the app hasn't updated to show recent trips since I did the software update but will give it some time to do so before trying the full reset.

At least I seem to have re-established remote communications.

TL;DR - under "Info & Security" check that both "Activate all data" and "Use voice data" are selected to "on".

[b] What settings did you reset in the info screen i.e which steps please 

I'd be interested to know that too please, did the upgrade and also got the greyed-out communication arrows and trips not appearing in the app ...

Are people generally having to ask for this to be done or is it being addressed proactively? I had this issue last winter so if it happens again over the next cold snap I will have to talk to the dealer ...

By the way not had an issue with the 12 V Battery, mine was parked up for a while recently and switched on immediately when required. Although I did disable keyless entry for the duration which perhaps helped converse the 12 V Battery.

Hopefully that is an error rather than by design. You need both ends to be locked to stop someone removing it. If the car is on a schedule then it should lock/unlock the charge port with the doors.

It doesn't seem to lock at the car end and I recall this being mentioned on a previous post some time ago. Maybe I should try the car schedule rather than the charger schedule to see if it behaves any differently ...

Nope, mine still making the noise as far as I can tell. At least it's about half the volume (subjectively speaking) of the one in other Toyota vehicles!

Is your charger on a scheduled charge? Mine had mysteriously changed itself to a scheduled charge which was easily overridden in the Hive app. If you plug in while it is on a schedule the charger end locks but not the car and the light on the charger flashes blue.

My subjective opinion is it feels a lot "quicker" than the various hybrids I've previously had and even a gentle tap on the accelerator is quite responsive. And this is in "eco" mode. Quite happy with the driving experience on this one, probably the best of the hybrids I've had to date.

I've had mine serviced at Derby the last two times (I had been using Coventy but felt their customer service had gone downhill). It seems that since the Toyota and Lexus dealerships are next to each other they use the same physical workshops for servicing. I don't know if there are "special" Lexus technicians that work on the vehicle. Also when I needed a replacement mirror cover guess where it was to be found when the order came in ... in the Toyota stores!

Good to see the car industry is keeping up their poor reputation against cyber attacks. 😞 

This one is probably down to poor IT ...

I'd avoid that SMMT link for the time being, while the address is legit the content seems to be something else currently!

The engine will also start if you select front demist. I assume the heat pump can't deliver heat fast enough to meet the legislative time for clearing. However if you pre-heat from the app the heat pump alone is used.

Good hint, I struggled with the same problem before finding this out. I believe you still need to remove the key blade before the top will slide off.

Mine started doing this yesterday too. Seems a couple of journeys haven't been recorded as a result. I wonder if someone was tinkering with "privacy" settings?

as above

1] the 12 v aux battery isn't charged by the engine, it is charged by the vehicle's low voltage supply which is provided by the hybrid system when it is in Ready mode. That energy comes from the high voltage traction battery, regenerative brakes or petrol engine as determined by the system. It isn't something you need to worry about or can control.

2] the petrol engine is started from one of the electric motors within the hybrid system, powered from the high voltage traction battery. The 12 v aux battery only provides standby power for retaining memory settings, the alarm and door locking/unlocking, and powers up the vehicle's systems to allow it to get into Ready mode when the hybrid system takes over.

As above [1] there is a component called a DC/DC converter which powers the low voltage (12 V) systems from the HV supply.

Because [2] the 12 V Battery is essentially only there to retain settings and power the vehicle up it doesn't need to be as large as one that has to have the capacity to crank an ICE for a cold start.

Hello,

I picked up my new 450h 2 weeks ago immediately noticed a rattle on rough A roads.  Went in on Monday and dealer fixed it as could not hear it on way home (A pillar drivers side). The next trip which was about 80 miles and the longest so far I noticed a new  sound coming from in front of me when at motorway speeds on rough roads (possibly dash or steering column), also now getting used to the car the steering wheel is slightly offset.

...

What tyres are on your car, I noticed something similar and complained to the supplying dealer who checked the suspension etc. and said nothing was wrong. Over time the noise disappeared. Then when I got new front tyres it has come back. Car was supplied with Yokohamas and front tyres replaced with these. So wondering if its something to do with the tyres.

Today a full charge showed 67.7/65.0 miles which I think is the best I've seen to date. Of course achieved range is still nothing like; I set off on a regular 18 mile journey prior to that charge today with 50 miles indicated and it used something like 30 miles of range although I was driving into a stiff wind most of the way.

I just got the letter (via lease company so a bit delayed in transit) but got booked in at Lexus Derby the week after next. Hopefully they don't then decide the part needs to be ordered 🙄

When I first got the car I was a little perplexed that A/C seemed to be "off" but the system seems to get the heating or cooling right - for example driving around in 30˚ ambient today lots of nice cold air coming out (at slight expense of EV range of course) but the A/C still appeared to be "off" on the display ...

I was told the registration for my car in March 2022 even though it didn't reach me until May 2022. (this was a fleet order). I think the way it works is that the dealer gets a block of registrations allocated and they may or may not let you pick one (I've had mixed experiences over the past few years on private new car purchases). The registration is notionally allocated to the car but it does not get "activated" with DVLA until the car is officially registered which is typically done on or just before the day of delivery. For my car this was done the day before delivery but it took a few days for this to be reflected in the public-facing DVLA records.

I'm sure most people already know this but the first character in the current UK scheme is regional, there are a couple of broad subdivisions for some of the letters but I'm not sure how allocation happens below that level. I searched some similar registrations to my car and found a wide variety of marques!

Charged before heading out this afternoon and it reported 59.9 miles predicted range. Achieved was around 47 miles. A mixture of speeds with maximum around 60 mph and some significant hilly areas.

I often find that the range drops more swiftly when the indicated range hits 25 miles. 

Interesting, I think my experience is similar, perhaps below around 30 miles.

After reaching 58 miles indicated from last night's charge, I did a couple of local trips then "topped up" giving an indicated 57 miles. I then did a round trip of around 50 miles, after 25 miles outwards the indicated range had dropped to around 31 miles. But I only managed around 23 miles of the trip back before the engine came on, so around 48 miles achieved in total. A mixture of different types of roads and speeds up to 60 mph.

This evening's charge (having completely used up the "EV" range today despite a cheeky top-up while out and about) has breached the magic 60 again - 60 w/o AC, 58.2 with. The indicated range has been creeping up again over the last few weeks now that the weather is warmer. I'm approaching the first anniversary of having the car and it has done 20k miles. I will see if I can get a good estimate on achieved range over the next couple of days.
