Gives a whole new meaning to regenerative braking 😂

I agree. The forum is rife with peoples batteries dying too often that too on brand new cars like the LBX, NX, Yaris etc. I feel like Toyota has had enough time and experience to learn that these batteries die within just a few weeks of no use. I feel like they should have updated the batteries accordingly. Also im not very familiar with battery chemistry but it seems like these newer AGM batteries are to be thrown away when they fail. I remember when lead acid batteries would last virtually forever with people using old school high voltage chargers to just boil off the sulphation. Add distilled water and its good as new.

I suspect that is exactly it. The GS is heavier than the IS hence it is tuned slightly differently because of the weight difference. Also better kit levels and a larger screen all probably consume some more energy overall.

While you are right you do need an AGM battery for start stop vehicles yours is a hybrid not a conventional start stop vehicle. The 12V battery is only used to boot or power up the computer. From that point on all battery needs are handled by the traction battery. Your engine starts are done by MotorGenerator1 in the gearbox which runs only on the traction battery. My advice to people looking to get a new 12v battery would be to avoid the genuine battery if your usage is not high. Theyre too small and fail too frequently if usage is low. But if your usage is high you should be fine with the original battery they do last long if the car is used regularly.

Yes the waterpump can be an issue on older cars. I had mine replaced too so check to see for pink crust around the waterpump. Its easy to spot its the only thing that is belt driven. If the car you are buying was serviced by lexus within the last 1 year it should have the relax warranty and should be covered. Just so you know lexus offer 1 year or 10k miles of warrany for up to 10 years or 100k as long as you service your car annually with lexus.

I agree with the above. Official paints tend to be of a higher quality. While the aftermarket ones do do the job as well the end finish is much better with the official one. I didn't try the lexus one yet but have used official paints from Mercedes and it was better thickness wise etc. But some after market ones come with a needle which helps with better application vs a brush. Also yes while they dont have an expiry date in my experience the colour becomes darker after a while. Might be down to the fact that i store it in the car and the heat from the sun etc denature it in some way. So maybe dont do that.

The battery warranty is for up to 15 years and unlimited mileage as long as you get an annual hybrid health check at lexus. This costs around £50 or 60 and is free / included in the cost of an annual service at Lexus. As long as you clean the hybrid battery fan filter once every few years and dont let your battery overheat it should be extremely reliable. Very few of these batteries fail prematurely. There are many members here on the forum that have 2013 2014 cars havent yet heard of any battery failures yet. Even if they do fail you can opt for an aftermarket reconditioning service which costs £2k or so. Anyway if you buy a 2015 and plan to keep it for 5 years sounds like the battery will be under warranty for that period anyway so you should not have much to worry about. Also if you buy cars pre 2017 the tax is lower only £10/20 depending on the variant. After 2017 its an extortionate £180 or around that.

Touchup paint is basically a small nailpolish like bottle but you can buy the exact colour for your car by searching for your colour code on ebay. The aftermarket ones are generally paint and lacquer mixed in one and is generally ok for touching up small spots like the ones you have. Lexus also sell official touch up paint with a separate lacquer bottle. Typically you just use the brush or needle in the bottle to dab a little paint to fill the white spot. If done properly touch up paint wont come off with washing and can be almost invisible.

Yes thats my understanding and others on the forum have even got an email confirming the same. Might be best to clarify with them. Mine turns 10 in Nov and i plan on doing the same thing.

Honestly if you plan on changing your car in the next year or 2 might be worth the gamble. But if you plan to keep it for the next 5 years go original. Else like the saying goes buy cheap buy twice.

I may be wrong but i think ending 40 is left and 41 is right or vice versa.

Are you sure the white stuff is mold? Asking because i had a similar issue on my IS300H when i first bought it and it turned out to be a leaking waterpump that splashed coolant all over. Coolant dries to a white powdery substance on black backgrounds. Look inside the engine bay and check to see if you see any pink crusty residue. Either way if its a car you are looking to buy perhaps look elsewhere as water should not be able to get to the isulation under the hood unless is coolant from the engine or someone tried to drive through a large puddle.

On a separate note you can get the 11th year free. E.g if your car was registered on the 15th of Oct 2014 for example. Get it serviced before it is 10 years old so maybe on the 1st of oct and you get 1 year more of service activated relax for the next 10k miles or 1 year.

Those look like stone chips. Fairly common on all cars in the front. Especially if driven a lot on the motorway. You can buy touch up paint from ebay or lexus and touch them in. I have similar marks on the front bumper they're way too many so i touched up the obvious ones ignored the ones that cant be seen from a distance or that are not on a metal surface

Got it in that case maybe try carista. Seems to have worked for someone in this thread

You cant delete it with an obd2 scanner. The error pertains to a safety system and is permanently recorded in your airbag ECU. You may find people on ebay willing to reprogram/reset your airbag ecu. But you need to fix the problem first i.e replace your pop up hood struts if theyve deployed or are malfunctioning. If they've deployed you probably need a new hood as well.

42410-30040 https://www.amayama.com/en/part/toyota/4241030040 Best price seems around £100 cheaper than the front fully shipped. Its definitely worth the wait for non urgent work in my opinion. Realistically it takes around 3 weeks sometimes as amayama dont always hold stock. They order it from toyota once they receive your order then ship it to you. But if its in stock i reckon it may come faster.

~240 usd for a front one on amayama. https://www.amayama.com/en/part/toyota/4355030071 Its double the price on Lexuspartsdirect

I think all IS cars come with tpms built in. Not sure if the lower variants don't have it. But mostly all have it and if you want it displayed on the instrument cluster then you can add this type of module from china https://a.aliexpress.com/_EJkKpoJ Thread on this here https://www.lexusownersclub.co.uk/forum/topic/132372-digital-lcd-display-tyre-pressure-module/#comments

Thats 540 a month or ~6500 a year every year. You won't be changing shocks or tyres every year. Also that seller made me an offer for those shocks i linked above he wants to sell them for 150 now. Perhaps offer him that. At least you will have one shock really cheap.

64725-50071 is the part number you are looking for. Google search it various sources will come up where you can buy it.

Quite surprised to hear that amayama is more expensive than lexus. Anyway im sure if you search the part number in google and scour the internet you will come across deals to be had. Here is one example https://www.ebay.co.uk/itm/355620279628?itmmeta=01J09RH1D2QBNJEWYP8QDK0SFN&hash=item52cc9ed54c:g:~ZYAAOSwqZJmFZrl&itmprp=enc%3AAQAJAAAA8EFJNTib%2B7wOpRNianwN8qrtZFnC2j2%2B759ApwO6fWx18mFdLcrvblfJeB5YOuwh12jQQxWPvGvfTe9LLHcxPUkWipuS3luU3cQ8yo9enlm5rqHsGORDyuxnsJz%2Fa%2B5%2F31BCBlqfEnBD4%2FeZU9DSI2%2BBrh1SBA1ULQuFLs0gKv2RQWXTVBvirPmAdOwiWi8FiZEcBeHPwrqSKq%2FscQ3T3Pe1VAmXsnxH4D7DdAOsW0sAt6ftK%2Bla%2BqMudAFw0Ua8svCuZb6rxZV0J%2B%2F6vTVQe%2FCKpbl74Lh%2BLe0CmjMJGY3lrlGqfBYB5OuHe3kh1wtxxw%3D%3D|tkp%3ABk9SR8yWxLiCZA

Yeah try that. And i totally understand. Its getting harder and harder to choose which car to buy with companies these days primarily offering SUVs and arguably not as well made as older cars. If you're happy with the car and plan to keep it for the next 5-6 years then spending ~3k on it makes sense. Thing to note is that £600 will only get you a replacement cell. I think most battery repair places also offer a reconditioning of the remaining cells for ~1200 or so. I believe they run it on some machine to get rid of the deposits that form inside that reduce the battery life e.g on a normal lead acid battery sulfation is what kills it and some machines can boil off these deposits. I feel like its something similar that they do for the NiMH batteries to kind of restore them to get the best performance. Maybe speak to one of these places and get a quote as this might make sense vs replacing 1 cell only to find out a year later that another one has conked off. Also on the shocks consider ordering them from amayama or other places where you can get original parts cheaper and fit them at a local indie that will save you a ton of cash as in my experience the cost of parts at lexus is sometimes double or even 3x the price of what you can expect to pay elsewhere.

Depends on why you want to change cars? Are you bored of the gs450h is it that you just want to experience something different now? If so then that rationale works. Else from a purely financial pov retaining your existing car is always the better option. Sounds like your decision to replace the shocks is not due to faulty shocks but because you think it might improve the ride quality? If so then i would say defer this job until there is an actual issue. If its actually damaged then i would say get a new car as thats nearly £3000 you will be putting into this car that could go towards you driving something newer. As far as fixing the battery goes. Independent garages/companies will replace the bad cell and recondition the other cells. So in theory it should last a good few years but like with anything else things can go bad again and you will be supported only upto the warranty period the company provides. So in theory you can get mayne another 2-3 years out of this car by spending £1200 or so on reconditioning the battery. At this point the car will be 20 years old already and you may want to change it then if not now.

The 2013 2014 models are notorious for failing water pumps. Mine failed in the centre at the bearing. I have heard of a few others failing at the bearing as well. Lexus later had a new part number for the stretch belt. So one hypothesis is that the older belt was causing the bearings to wear prematurely causing leaks.
