Pull up front edge of rear seat - there are two clips retaining it and they are quite stiff. You can remove the squab completely by pushing the rear of the squab over the two rear retaining hooks or just angle it upwards and use a suitable sized prop to hold it.

And so we come full circle - again.

Which proves that a bit of research on your part would have revealed that a hybrid, perhaps even especially a Lexus hybrid, just does not meet your needs and is not compatible with your driving style or driving habits.

There's a problem and people have told you how to handle said problem, ergo it is a problem no longer.

You have two options (a) change the car, or (b) use a workaround.

Continuing to be Mr. Angry on here will get you precisely nowhere except for stress-induced hair loss or worse.

Sorry, but clueless. If you had bothered to read the thread before diving in with your self-prescribed expertise you would see that I have owned hybrids and full EVs previously, none of which were ever bedevilled by 12v problems. Hoisted on your own pitard I'm afraid. I have zero idea why you are in a thread for LBX owners, other than to pick an argument? And finding a workaround never solves a problem - it hides it and makes excuses for it, but never solves it. The underlying problem can only be resolved by an engineering solution which removes the need for a workaround. And again, if you read the thread, I have a new Battery so have my own workaround or solution - time will tell. Please desist from responding as having to correct you repeatedly is tiresome. Final correction though - highlighting a deep rooted issue with a £42k vehicle is constructive, and not "angry".

Because it's an electrical problem and having been in the electrical / electronics field all my working life, I do have a certain knowledge and understanding that I hope may be useful to people with those types of problems.

This is true but Lexus will not do anything retrospectively to the cars already out 'in the wild' so your continual complaining will never be of any benefit to you yourself.

Great, so your problem is solved and you have no further need to complain anymore. Sorted :yahoo:

We are looking to buy a new car sometime, but not too seriously as our 10 year old Toyota has had only normal wear and tear issues and only one genuine fault- a faulty indicator bulb. The LBX and Audi a3 hybrid are on my radar, so I have been studying the LBX 12v Battery problems and the similar Yaris/Cross 12v problem (125 pages on the Toyota forum). One of my solutions to the 12v problem might be to not buy an LBX. 

I live only 3 or 4 K's away from our Toyota dealer and thought I would have a look at the solar chargers on their Yarises. Not a charger in sight!.😲 I of course got collared by a salesman who seemed genuinely perplexed when I asked about solar charges. 

The reason for no chargers on Yarises and presumably LBX's maybe because I live in New Zealand and when I interrogated the Lexus salesman a few months ago before I knew about the 12v issues he told me-

It has no built in Sat Nav, you use for phone somehow.

There is no Sim card, doing whatever sim cards do on UK LBX's

Not all "Hey Lexus" features are available here.

And possibly not so many EU bing and bong warnings here.

Possibly these issues are not draining batteries as much here as in the UK.

Just a thought.

Thank you for the photographs. I’ll give it a go.

Some additional points to help:

1. Prop up seat squab with a piece of wood to give you plenty of room to work

2. There is a felt covering over the Battery with white retainers holding it in place. Use a sharp knife to pull the centre plug out which will allow you to remove the retainer. Only need to remove two

3. For better access remove the lower plastic panel held on by two black retainers. Again lift out their centres before removing them entirely.

4. Disconnect the -ve Battery cable using a 10mm socket 

5. There is a red plastic cap over the +ve terminal. Remove by squeezing the hinge end plastic tabs to release the hinge pins - it is a bit of a bugger to get out.

6. I found the best connection to be via the larger 14mm (IIRC) nuts on each wiring assembly rather than the smaller 10mm nuts used to secure the clamps to the Battery posts.

7. Refit in reverse order, connecting the -ve last. Job takes about an hour.

In my case I fitted the Ancel BM200 Battery monitor (£16.19 off eBay). First test showed Battery at 12.13V and 30% charge but car started several times no problem. I left the car in Ready mode for 45 minutes and it showed the Battery at  12.31V and 95% charge:

I should add we have never had any starting issues with the car even after a two week stay at an airport in October. Only did this for a bit of fun and interest

A bit off topic, I can tollerate it, except when in EU bonging overrides navigation voice in Android Auto

Today, there were no issues starting the engine after the car had been parked for a week (no wonder, given the fully charged Battery following the Lexus Battery Xchange). On Monday, I'll be installing a BM200 monitor, which will allow me to track the Battery more accurately in the future, and share this experience with you.

However, I believe that, in general, car owners should remain vigilant about their 12V Battery after any service—whether it's a routine inspection, wheel change, or even the delivery of a new car. Often, service centers don't fully recharge the 12V Battery, which can lead to long-term imbalance, particularly for owners who do a lot of short-distance commuting or drive in poor weather conditions (e.g., dark, rainy days). This increases the risk of the Battery failure.

I’ve experienced this issue occasionally with previous cars, even those with fewer electronics, but it would typically take about two weeks for the Battery to show signs of strain. The Lexus LBX seems to require more attention in this area, but Lexus hasn’t adequately addressed it. While earlier Lexus models included a 12V Battery voltage monitor, this feature has been removed in newer models. As a result, I’ll need to install my own monitor at my expense. I’m unsure why Lexus decided to eliminate this feature, but I suspect it was because the voltage readings were confusing for non-technical users. Nonetheless, Lexus should have at least made it an optional feature, rather than removing it entirely.

And Hey Lexus: are you aware that it is not allowed to have engine running while not moving the car for longer than 1 minute, at least in my country (EU). So the solution to charge Battery by staying in READY mode is not that brilliant solution.

I managed to pull up the passenger side, but I can’t get the driver’s side up, despite considerable force. I think it’s a job for the dealer, they can break it!

You need to hold it in the middle of each seat. If you lift the squab up you can run your finger along to find the clip. Do not try lifting at a point any distance from it as the seat will just flex. Once you have the correct position just give it a sharp tug. It is a metal in nylon plug/socket so nothing you can damage really.

What is the point of you wasting your time complaining on this forum when your issue is with Lexus. They don't read these boards.

They do.

What Battery problem?😲. In fact we don't even have to mention the 12V Battery. Here is the information from the New Zealand Lexus site.

_________________________________________________________

Leaving your Lexus stationary for extended times is fine, especially if you keep the following points in mind:


  • Keep the fuel tank as full as possible. Even if you are not going to drive the car, leaving it at least half full will avoid potential damage to the fuel tank.
  • Increase tyre pressure slightly. This prevents the tires from wearing out while stationary.
  • Start the car once a week or every 10 days. Let it idle for a few minutes and turn on the air conditioning. Disable the recirculation feature before turning the vehicle off to prevent bad odours.
  • For those of you that own hybrids, don’t worry. Unlike the Battery of a conventional
  • vehicle, the hybrid Battery needs no maintenance, even if it’s not used for months.
  • Finally, if you really must drive, do not forget to disinfect the interior of the vehicle before and after each trip.
