Please help - RX 450H Stopped suddenly on the road - IGNITION ON SIGNAL
Hi Guys,
2 weeks ago i bought 2017 RX 450H f sport, because car was stopped under sun for almost 3 months without driving 12V battery was dead. After we charged it and everything was ok. I was driving car for arount 1 week but yesterday suddenly engine turned off on the road and car was running slowly on hybrid battery for around 1 minit after i stopped because it was not moving anymore when i was pressing pedal.
Firstly Check engine, stop car at safe plase and visit your dealer was written on dashboard, after shortly IGNITION ON signal was activated and after couple of second all signs was on and steering also got stuck. I just called recovery and bring car at home. Will share photos of dashboard signs here and please advice me what to do now. I think it is all because or 12 V battery is dead again and engine did not start because of this.
Please see the photos and advice me what should have happened and how i can fix it.
If it's new, why can't you just bring it to the dealership and have them fix it under warranty?
You could try measuring the 12V battery with a multimeter. If it is dead, simply replace it and see if your problems go away. Next time consider investing in a battery tender for long vacations.
Thanks for replying. The thing is that I imported this car from another country and still not registered under local dealer warranty. I will try to change battery first and hope it will help. Otherwise will take it to dealer but without warranty im sure they will charge me a lot .
I was on vacation right after I post here, today I am coming back to home and will update you with the news, first i will replace 12 V battery and will see what will happens.
You can not believe but it was all because car run out of petrol.
I changed the battery car started all right, I drive 10 meters still same issue, all checks on and it stopped on the road. We took it to local workshop and after checking on computer 1 hour we couldn't find what was the issue. Computer was showing all system faults including engine fault. Finally I remembered it was showing petrol sign on when it all happened that day, though range shown on dashboard was still 15 km. (I think something happened with petrol sensor who showed wrong range). We put 10 litres of petrol and car started OK.
So please consider never run out of gas on your hybrid lexus. Once u run out of gas then car is literally dead not working nothing.
Thanks for your attention and advices. Hope it will be good experience for
New update about petrol issue. Every time I have less then 15 liters (approx 4 gallons) petrol in the tank car is doing same thing I posted before. It is stopping and all checks are on before you dont fill up the tank with some petrol.
Can anybody advice what might be the issue? Might petrol pump is displaced inside the tank and can not suck petrol to the engine once it is less then 15 liters? Is that possible? Since I dont have warranty because car was imported from neighbor country they charge huge amount of money if you bring car to local dealer.
is the low fuel light on ?? what does distance to empty say ??
is everything fine until it hits that level ??
could be a fuel pickup problem, (doesn't sound like a vent issue) need to do some diagnosing, **these may not be an exact fit for your vehicle, just an example** (please check your model for exact parts)

Hi JSracer,
Thanks for the reply. First time it was showing fuel sign on (yellow) and distance around 15-17 km. Second time it did not even show yellow petrol sign and remaining distance was more than 70 kms. I parked car and could not not start it later after 4 hours. When i put some petrol it still did not work. Then i removed cable from 12 V battery and put it back to restart the system. After that car started all right.
