hybridbatterysolutions

If it has been off the road since Christmas it is very likely the Hybrid Battery has discharged beyond the point of being able to turn the engine over, hybrid vehicles really do not like being unused at all. Although the hybrid battery is physically large and arranged in series to provide high voltage in reality the battery is relatively low capacity at 6.5Ah. My advice would be to charge or renew the 12v battery first then try again remember to hold your foot on the brake when you press the button. If it does not start there should then be fault codes lodged along with the normal "check hybrid system message" at this point you can retrieve the fault codes & go from there. Hope this helps.

As am I to level 4

That's no problem sir more than happy to help. Gotta keep the wife happy, happy wifey happy lifey!😂

Ok for a 6 months or 5,000 miles guarantee (whichever comes first) on a GS450h the cost is £650 - within this cost I give up to 4 replacement modules FOC. if more modules are needed I charge £35 each for them, the guarantee is limited to only those modules that I replace. For 1 year or 10,000miles guarantee (whichever comes first) with the same vehicle the cost is £745 - within this cost I give up to 4 replacement modules FOC. if more modules are needed I charge £35 each for them, the guarantee covers all the cell modules. Hope this helps. I would put a link in for my website but I was taught to be cautious & do not want to fall foul of the forum rules.

Hi Linas. That very much depends on the length of the guarantee the customer requires as I have the ability to repair the pack to different minimum capacities. The customer chooses the guarantee length they require & I let them know the cost, this varies from customer to customer & is also obviously dependant on the capacities of the remaining modules.

Hi Kalpesh - I have a lovely Canterbury Blue GS450H SEL in for repair at present this is the the model with the excellent Radar Cruise & sunroof fitted, it has @90,000m on the clock which is very low with the cream leather interior which is in good condition. The owner wishes to sell it after repair (As soon as the AA give their go ahead!) I last repaired it in August of 2022 at that time the owner only selected a 6 month graded repair - that was 19 months ago!! not bad aye? Early diagnostics reveal at least 2 cell modules are down but the full extent of what is needed will not be known until I have taken the hybrid battery pack out of the car and carried out full discharge testing of each of the 40 modules over time, I can see that the tpms sensors need doing & there is a scuff/scratch on the N/S/R I would estimate @£100 to repair. I think (dont quote me) that the owner is asking in the low £4Ks for it, I think it would be a good buy for someone. If you or anyone else are interested feel free to message me & I will give you his phone number. Best Regards Richard

There is no reason why a GS in good hands cant last at least as long as an SC & economy wise given the SC's consumption around town I suspect the two models would break even if not even slightly better for the GS

I think we will have to agree to disagree on that one.

If the supplying garage needs a specialist I am happy to offer my services, many garages that are not familiar with Hybrids bring their vehicles to me.

Well for my money it's got to be the GS450h if you want comfort speed & reliability. I regret the day I sold mine for a fling with an SC430 which is not a patch on the GS.

Yes not good, what minimum capacity range would you like

Yes I am still doing my thing, what exactly are you after?

Hello All, If you have this fault you have my full sympathy The First thing to be said is despite the fault description - I have never ever found the driver unit (ECU) to be at fault ever. When I had this problem with my GS450h I was able with the assistance of Carl911 to repair it myself & I have in the past taken the job on for a few of my customers with the proviso that if the speed sensor magnetic ring inside the pump breaks during strip down it will necessitate renewal of the whole pump at around £1100 ish plus fitting. The job itself can be quite tricky especially if you are not in the mechanical industry & I can fully appreciate anybody's reluctance to tackle it themselves, so I just wanted to let you all know that I can now offer this service generally at less than half the new unit cost with the same proviso as before. So if you are unfortunate enough to require this repair please feel free to PM me. Richard

Its definitely worth doing both bearings & any seals you see, provided you can remove them relatively unscathed any good bearing supplier should be able to match them no problem, one thing i would say is get the best quality available. The other bearing & by far the most difficult to remove is under the circuit board which is moveable after screws are removed but be very very careful as there is a circular magnet which i believe is part of a speed sensor which is very very easy to crack or chip - once that happens you are in the do-do, you can only de-solder the connections if you have the correct solvent to remove the coating on them which is probably acetone/alcohol based. As for interchangeability its best to check with Toyota parts i'd say. That sound you heard was deffo the auxillary transmission oil pump.

Hi fellas - yes I am still doing my thing. Thanks Richard
