Many thanks. It’s an f sport so assume has wireless charging as standard? 2016 model but appears to have the 7” display but control knob rather than the trackpad. All others seem to have the trackpad, but it’s in the colour I’ve been after and otherwise looks great. Paying 19.4 for 2016, 70k

I'm about to buy a 2016 F-Sport tmrw. Every single review seems to say the stereo has a terrible user interface. Coming from an Rx450 with the joystick/mouse sure I'll cope though! Mine seems to have the bog standard 8 speaker basic nav package with a rotary control rather than the touchpad. Most other F-sports seem to have the remote touchpad. Is this the case that most original owners specced up (except mine!). Presumably I still get wireless charging as Fsport? But unclear if this includes AD2P media streaming etc.

More drama! So, thought I'd give it one last shot. Unplugged the negative terminal from the battery to give it a complete reboot. Thought I'd leave it at least 10-15 minutes as previously when I swapped the 12v batteries over it was only about 4 mins or so between the old one being disconnected and the new one plugged in. As it was raining I then stupidly closed the boot & then when I returned 10 mins later realised it was battery powered! A bit of crawling over the back seats, managed to lift up the boot floor and reconnect the battery, so all in had around 30 mins of disconnection. Everything seemed reset. The clock went back to 1am, and cleared the warning triangle. Drove off, leaving the fans off to isolate the AC from the system (just in case this was triggering it). Kept on driving, and driving, no warning light. Went for 20 mile drive and returned home, and still working fine with no triangle. Right, must be the AC compressor causing something to go wrong then. Set off again, putting fans on full, enabling AC, heated seats, the lot. Again, kept going up and down the A3 for 30 mins and nothing! Practiced pulling over, turning the engine off, getting out, locking, going in again and setting off & it didn't miss a beat. I do not know what is going on but the car is now pulling the best MPG I've ever had (getting 36 on the dual carriageway in 3 degrees, when I never usually beat 27!) and just feels so much better. Obviously I'd been driving with a failing 12v battery since I've owned it the last 2 years, but maybe somewhere in some system it hadn't cleared the previous battery concerns or crashed somehow throwing up false positives??? Truly baffling, but my car feels fantastic and I'm over the moon.

Will try and get up on ramps and have a good rummage around tmrw when light to see if anything obvious (actually hoping to find mouse droppings/nest) 🙂. Aircon was regassed 2 years ago as part of full service so don't think it's that. Given the inverter doesn't appear to be leaking any fluid, is working and orange warning triangle not red, perhaps it is hopefully something as simple as a perished cable shorting somewhere. I'll see if Lexus get back to me tmrw and ask how much they'll charge for the diagnosis & then can review my options & emailed a couple of Toyota specialists nearby to see if they would be able to investigate.

Looking inside the engine bay the inverter looks bone dry, no obvious leaks or damaged cables 😞 Have a horrible feeling this could be the inverter on the way out 😞

Thanks so so much guys. Progress! I made sure my VM running techstream was routing its network through my mac & it now gives the ice logo and data list doesn't crash! Ok, so I have p0aa6 as the fault, and drilling down further i have.. Detail code 1: 526 Detail code 2: 614

To be fair I wouldn’t touch them normally. My Lexus failed its MOT during lockdown due to corroded parking brake cables and couldn’t get an appointment with any Lexus garage for weeks. They did a fantastic job and kept me fully informed on progress & saved me hundreds compared to main dealer. It was a horrible job due to the corrosion of the parts (the underside corrosion was so bad I got it rust treated and sprayed last year) and didn’t charge me extra despite the extra time needed to get everything off. if they can at least pinpoint the exact fault for not a lot then if and ring around and find specialist or back to main dealer.

And I'm thinking of taking it to the Twickenham dealership. That's bound to be cheap 🙂. My local Halfords autocentre do Hybrid servicing so may swing it by them first (they did my parking brakes earlier in the year). Sorry am I being thick with TechStream? I go into the Hybrid option, do the "hybrid control live" & see the P0AA6 under "diagnostic code" & the only option I have is to reset the mil or freeze frame. How do I drill down further?

Thanks again all. I’ve had it on all morning full heating and left it in ready to transfer energy from hybrid to 12v (just in case the new 12v wasn’t fully charged). Unfortunately, my tech stream doesn’t elaborate on the poaa6 code as it’s offline. I did actually pay for the day’s access but the licence key didn’t work so ended up using the dodgy copy that came with my reader. No sign of any water ingress around the battery pack. Cleared the code and after 3 minutes the code came back again, so whatever is causing the fault still occurring. Have left a callback for local Lexus garage to get booked in next week. If it is a fault within the hybrid battery then at least I’m hopefully covered by the warranty. Presumably labour charges not too high (famous last words!) as gaining access to the battery pack seems quite straightforward. Unless anyone can recommend a decent hybrid specialist in the Surrey area?

Thanks. Given I service it religiously at Lexus dealerships each year, just noticed the last essential service in november should include the hybrid battery check which protects me for a further year or 10k. Trouble is this year the dealership didn't provide me the hybrid health check report as they do usually (was in a rush to collect as they cocked up the service, making a while you wait appointment nearly 5 hours long as they were insufficiently staffed and their cleaning machine broke down halfway through the final clean!). Presumably as I've paid for this service & it includes an additional year's warranty on the hybrid battery I should just book it in with the dealership and if a fault within the unit be covered? Although no reference to the health check in my documents, there's no doubt this essential service should include a full hybrid check and warranty? Lexus Essential Care | Lexus UK

Well I spoke too soon. Out for about 10 minutes today and dreaded light re-appears 😞 Ran Techstream and it's P0AA6 0 Hybrid Battery Voltage System Isolation Fault. Reading similar posts from Prius owners about this occurring in cold conditions, I'm hoping it's just the car not liking the -1 degree temperature or a bit of condensation caused by cold conditions and then subsequently driving and heating something up (it only kicks in after about 2-3 mins of driving). Similar issue on an Rx400h. Where Ice had formed inside the hybrid battery: Hybrid Battery Isolation Fault - YouTube I'll wait until the weather warms up a bit and hope it goes away. Sadly losing confidence in the old girl so might hasten up the part-ex to an NX300 as soon as Lexus garage re-opens.

Took the old battery out and it had been leaking badly. Definitely the cause of the wetness in the boot. Cleaned it all up and fitted new Panasonic battery. Cleared the dtc errors with tech stream and took it for a 30 minute spin. All much better, not one single problem or hybrid system alert and everything working as expected. To be fair the build date on the battery was 2009 so it held up pretty well. Thanks so much for all the help and advice, much appreciated. Still find it bizarre there’s no low auxiliary battery indicator or warning despite there being a battery light on the dash and its computer able to read its voltage! Hey ho, just over the moon it’s not a costly hybrid failure.

Took rear seats out and luckily no dampness round hybrid. The water round the 12v battery thankfully appears to be acid (as fingers felt a bit funny afterwards). Chucked Techstream back in this morning & the 12v battery is now reporting 8v 🙂 Check Airbag SRS light now coming up & car won't go into ready, wing mirrors sluggish to close. Fingers crossed it's the original diagnosis & faulty 12v battery after all! Just got to be patient and wait for the new one to arrive. Thanks for all the help guys, much appreciated.

So my cable and Techstream arrived. Hooked it all up & getting error code "P0AA6 Hybrid Battery Voltage system isolation fault". Auxillary Battery showing as 14.24V. However, when looking in the boot I noticed it a small puddle of water under the 12v battery. Not sure if this is leaking acid, but also appeared to be a bit of moisture around the other leads in there which look hybrid battery related. Doing a bit of reading it can report a false positive with this code if water has got in or in extreme cold temps. I ordered a new 12v battery from Lexuspartsdirect anyway to play it safe & will open the boot up at the weekend and set to work with kitchen roll to soak up any residue. With the extreme weather conditions over the last couple of weeks wonder if a small bit of water has got in from the torrential rain or the extreme cold has caused condensation or one of the kids has dropped a leaking bottle on the back seat (not unheard of) & it's flowed down to the lowest point (the battery compatment).

Fantastic. Just been out in it and the hybrid system appears to be working properly & car behaving normally (still has the warning triangle on). It pulls away in electric mode & the hybrid battery shows the charge levels going up and down when driving (just disables the display showing the power flows on the dash and main screen). Fingers crossed it's just the system reporting a dodgy 12v battery.
