Lexus GS450h Hybrid Battery Repair

[@blktger]

I noticed you were able to use needle nose pliers to remove the orange plugs, however the proper tool to use is actually on the end of the handle of the hybrid battery service plug. I didn't know if you knew that or not.

[@gary2turbos]

Thanks for the hint Tony

[@billlam468]

Tony Lei , where is this orange circuit breaker handle? I'm up to this point of disconnecting my battery. Many thanks

[@blktger]

@@billlam468 It's the orange hybrid battery service plug you removed before doing any work.

brilliant video - clear and concise. most helpful, thank you very much. Wish all were like this!

Thank you Sean for your kind comments.

[@Sunsetsurferforever]

i have to thank you, this video was very good help, now my GS 450h runs perfect again. Just bought an battery re conditioner and replaced one battery cell (nr 19) which was low. It took a while to go through all the battery cells but now the car runs longer in ev mode. The whole job incl. cost for batterycharger and battery cell was about 70 pounds. Very sweet and easy to understand english in the video. Thanks alot from Sweden.

[@gary2turbos]

Hi, Great to hear your car is fixed - well done, glad the video helped, another hybrid Lexus saved 🙂👍🏻

[@billlam468]

Hi Lasse. I'm in the process of reconditioning my hybrid battery on my GS450H , can you tell me how long does it take to remove the battery out of the car. Thanks

[@Sunsetsurferforever]

@@billlam468 Hi Bill, it took me about 2 - 3 hours to bring it out of the car working carefully, this video was wery helpful. To lift the batterypack out of the trunk requires 2 person to do it safely. Be careful there is sharp edges, use gloves 👍

[@billlam468]

@@Sunsetsurferforever Thanks again for your help 👍

[@billlam468]

@@Sunsetsurferforever Hi again Lasse, from your experience with your repair, do you know if is possible to remove the Hybrid battery cover whilst it's still inside the car? because I bought the Prolong Hybrid battery reconditioner which is a plug and play system so maybe no need to take the whole battery out but I will need to connect the harnesses to the battery. Many thanks again.

[@stickznation]

Thank you sooo much for this video! I took on the challenge and did mine yesterday using ur video as my guide. It was awesome! Turned out that all of my cells were good and it was just a corrosion issue with the connectors. I removed the corrosion and applied the dielectric grease to help prevent it from coming back. She fired right up and…after 12 hours later…I was back on the road. Thank you!

[@omerward9261]

fantastic video no music no bs fantastic. will the car work with the battery connected

[@charming0077]

Thank you so much for making this video with such details, to replace a battery here in Canada is impossible so expensive and I'm wondering where I could buy a cell if I open it up. Also my gs450h is still drivable with all the light on dash will it not be drivable if I take the hybird battery out?

[@gary2turbos]

Hi, glad the video is of some use to you. It may not necessarily be the battery, if you can get to shop or acquaintance who has Tech Stream it will help you narrow it down. You can buy the cells on eBay, no doubt someone will ship to Canada. If you remove the battery for repair the car will not drive as it needs to see the whole hybrid system as healthy to drive properly. Good luck with your repair 👍🏻

[@yucolin3876]

Once there is one cell going out then chances of having to replace another one will be very high as the battery ageing. Which mean eventually you will have to change out at least half of them in a few years. The problem with the GS450h it has 40 cells and to gain access to the cells take time and labour intensive. Therefore I would recommend people if you are going to keep the car for another 8 years or more then you should replace it with a brand new pack from Lexus. If you just planning to drive it for another 3 years then just recondition them and cross your fingers. Btw Good Video 👍

[@TheJohnaddison10]

Very competitive video and well narrated. I jave this problem but the makers of this video have way more confidence than I. I think I will call the garage. Thanks though.

[@gary2turbos]

If you are worried about it then take it to the garage, the cost will make you think twice though, good luck what ever you decide

[@TheJohnaddison10]

I'm game to try but i don't know how to diagnose which cells to replace. Any advice?

[@gary2turbos]

All the info is in the video, if you don’t understand any of it best not to attempt it yourself.

[@TheJohnaddison10]

I was slightly distracted when i watched so i missed that bit. Autocorrect wrote competitive in my inital post. I meant to say comprehensive. Thanks Gary. I will study the video and give it go.

[@gary2turbos]

Take your time and watch each step a few times to avoid going wrong, good luck!

[@skoda110]

Id love to buy one like this. Challenging job. I recommend testing each cell with tester or measuring volt drop from full charge and then balancing them all for a while. Swap them around so in the middle u put better ones due to heating exchange issue. Good luck.Clever girl u r by the way

[@kotekKot-kr1bp]

Nice video! I don’t know if you are a tutor or teacher, but if not you should be 👍 great job!

[@gary2turbos]

Thanks glad you liked it and hope it helped!

[@r4assemblies330]

great detail, thanks. Roughly how long should the car be drivable on a fairly good battery only? 5 min? 10 min?

[@gary2turbos]

The number stamped on the top of the cell next to the breather port is 02XNKA 06917A

[@richardmock3198]

This was very helpful 😀 I’ve got the gs430 , but one day I would like the hybrid, so it’s good to know I could fix it myself 🤩

must be moisture or damp getting into the battery area for this corrosion to take place.. Check for leaks, Ive got a RX and they leak alot from the boot so best get that checked out otherwise you;'ll keep having this issues.,,

[@janke29]

Hi great vid and hopefully i will manage to complete the task as described. i got gs450h 2007 130k miles on the clock and upon check with an app found one or two modules are weak or dead. just wondring that your car 12 volt battery is the standerd batt or its a start stop. coz my panasonic 12v start battery is fitted with temp sensor and they are quite expensive. can we fit the standard battery ?, if we can then how to get round with the temp sensor ?

[@gary2turbos]

Yes you can- just pull the temp sensor off and refit to the new one

[@zhongqianzhao4313]

Hello, I have a few questions when removing the battery. First, how to remove the screws of the rear seats. I used a 12mm socket, but I couldn't remove it. I used an Impact gun, but I couldn't remove the screws. The same thing happened to a few screws fixing the battery to the body, I want to know what tool you use, thank you

Any idea what a total 3rd party battery replacement cost might be for a 2017 gs450h?

[@gary2turbos]

Sorry afraid not

[@guidobraun2920]

Only defective modules can be found via the voltage. With a capacity measurement, weak modules can also be found. These weak modules are among the first to be broken the next time. I found a 7.4 volt module with only 1800 mAh. Normally old modules (year 2007) have approx. 5500 to 6500 mAh. Here you find the way to check the capacity of your cells: kzbin.info/www/bejne/nWaucoOdmpKZbKc

[@gary2turbos]

Thanks for the tip Guido

[@sunra8437]

I have checked all 40 battery cells and they all showing 8+ not 7 ,5 ?so I’m guessing none of them needs to be replaced. I then cleaned the copper connectors they were not as bad as yours and putting everything back my hybrid light is still on and battery isnt charging at all. What other issues I might have with my hybrid?ok quick update 5 min after reconnecting hybrid battery all is working perfectly as it suppose to again. My battery is charging and hybrid check light disappeared!im so happy now. . Thank you so much you are the star!

[@douglasheld]

Maybe check your voltmeter?

Hi Sun Ra , i seem to have the same problem as yours, all my cells were 8+ but i did a battery reconditioning to mine, can you tell me what exactly you did for the battery to work properly again because mine doesn't seem to be charging as I'm driving and the warning messages "check hybrid system" is on.

[@2gr775]

if i only want to remove the fan for cleaning, do it need to pull the orange plug as well? Thank you

[@gary2turbos]

Hi, I wouldn’t imagine so but as is run off the 12v battery but as we removed it anyway then I would advise you do the same, it’s easy to do and better safe than sorry in our book, hope the video helped thanks for watching

[@SacreDro]

Any tips on what to look put for when buying one?

[@gary2turbos]

Hi, The Lexus owners club has some great information on what to look for, try this link: www.lexusownersclub.co.uk/forum/topic/106557-buying-a-older-450h-what-to-look-for/ In our experience its hybrid alarms, rear suspension strut leaks and if you’re looking around 100k mileage check if the water pump has been done, if not it will likely be imminent. The exhaust can suffer corrosion too. Good luck

[@Lowwdxn]

I have a 08 gs450h that currently doesn’t work and I’m not sure what’s wrong with it, the last time I put it in drive it just started shaking really bad maybe you can help out.

[@prestyns8235]

Are you able to unplug the hybrid fans and drive the car still? My 450h has gone to the point where it won't drive for more than a minute I have a shop just need to get it there. The hybrid fan is malfunctioning.

[@gary2turbos]

If the fan is on all the time it’s a sign the battery is degraded so neeeds rebuilding , I don’t think the car will drive without seeing everything in the hybrid system as good

How it Cost everything. Wanna know kuz one guy got a Gs 350h for sale very cheap on add it says need like 450dllrs job it had it park for quiet some time ..and the cells problebly need to repaced if you can help Thanks.

[@gary2turbos]

Hi, was able to get a cell for £30 - £40 from a breaker, that’s really the only cost it’s more the labour involved on the repair and of course how many cells need replacing, hope the video helps!

[@BROWNEPR1D3]

My brother has the exact same Lexus and it’s starting to experience the same issues. But I was curious as to if the 12v car battery located beside the hybrid battery could also cause some issues with the hybrid system? Thanks in advance!

[@thomasbirchmeier7924]

If the 12 V Battery is low on Voltage you will also have the Hybrid error. Charge it with a good Battery reconditioner ( Ctek ) but with low current for the AGM Battery. Regards from Switzerland.

[@kubiyoshi2744]

I read somewhere that after changing cell you have to do battery balancing to make it work properly. You didn't done it and its working alright?

[@autorecon]

In general I know that batteries get “worse” over time with usage But if a lexus gs450h has been driven 30000kms(around 20000 miles), is the battery going to be ALMOST as good as new considering that the car has been driven so little I ask because I have found a clean 2007 gs450h for 19k with 30k kms on the clock and I was wondering if the battery could be a problem in the near future in case I bought this car

[@gary2turbos]

Hi, wouldn’t know unfortunately if the high mileage or age is the issue for the battery, but if you have watched the video then you can see it’s fixable with very little mechanical knowledge, like most repairs it’s just about having the bravery to give it a bash :)
