Default Rx500 unable to start probably hybrid battery issue?

Hello i have friend with rx500 , let me share the story,
he ordered car from USA, brand new, car is hybrid 500h,

car have been travelling for probably 6 months in the sea ship,

car is not able to start, he was in some service today , service today claimed, that his issue is system voltage low, is it possible the hybrid battery to be the issue if so, how this battery can be recharged on that car rx500h ?
is there a charger if so whats the part number or some way or is there a way car to be forced via service repair people and techstream to charge the battery or not , car is not able to start.
All of the modules have errors but hybrid system errors are system voltage low.
car battery12v is brand new and have power.
also other error is lost communication with dc/dc converter control module?
I try to help any suggestions are welcomed, car warranty is not covered in our country since car is imported.

The manual covers this. Even jump-starting a hybrid is not straightforward. https://www.lexus.ca/lexus/en/know-your-lexus/manuals

This is way above my pay grade. I would try a Toyota dealer or the dealer from whom you bought the car if there is no dealer in your country.

You have a lot of investigation to do. Example: https://www.lexuspartsdirect.ca/a/Le...1-3F57FAA47914 $6000 for a battery!!!

I'm not aware of any cherger for the hybrid battery, and so the only way for an owner to charge it is via the engine or regenerative braking, and unfortunately the engine requires hybrid batttery power to start. As such, I think the only way to get it charged is at a Toyota/Lexus dealer. In any event, if this is a new car, then the responsibility to get it charged is with the supplying dealer.

I have to believe that it is a design flaw if the regular 12v battery could not start the car ICE engine which could then charge the traction battery. I mean I see my RX350h sometimes say hybrid not available due to low traction battery.
But yeah, the OP is in a pickle since they are nowhere near the selling dealer. I am not even sure how you would ship a car and keep the traction battery powered up.

Not so much a design flaw but a result of there being no starter motor, and the engine being started by the hybrid system. The 12v battery is just to power the electronics and fire the system up, which is why it's comparitively small on a hybrid. Other than in exceptional cases, it's more of a feature than a flaw.

If the car is new then I assume it was bought from a Lexus dealer, in which case I imagine they'd have to arrange for a local dealer to pick it up and charge it. If I was the OP my first action would be to contact the selling dealer to see what they say, rather than trying to figure out how to charge it myself. Failing that I'd contact Lexus.

I always thought that the engine charged the hybrid battery. Can't it be started with the current state of discharge? Then, the engine would charge the hybrid battery.

I HAVE noted that there doesn't seem to be a nearby dealer! Really, six months dis-use on a slow boat?????


This is WAY BEYOND my pay-grade too....

I don't believe so, as there's no starter motor, and so the engine needs the hybrid system to be available to start it.

After doing a bit of searching, it seems that there's something called a grid charger for hybrids. My guess would be that the main challenge would be finding a suitable interface/plug to connect to. Might be worth contacting these people to see if they have any ideas:
