What a brilliant video Lexus should do something about this problem .Post more updates on your car and how it has kept dry

[@franklinblunt69]

Thx for the presentation, sry for the troubles. I haven't had this but will perform inspection & prevention.

[@youtubeaccount7137]

Why is this not a warranty case? I mean it should not be possible that water reaches so far?

[@chris6796]

Happened to me last week. Had to have the whole battery replaced

[@adegboyegaolanrewaju1696]

Have change the power unit still write check hybrid system pls help out, is it compulsory to stcrew back to bolt before it will ready

[@adegboyegaolanrewaju1696]

And I scanned it, the code is p3030 means there is disconnection between Ecu and the battery

Thank you, It was really nice video . I have same problem with my rx400h too. Did you replace cells too? Why you do not put video how you replace it?

[@mabjawaid]

Just got battery control unit replaced. No need to replace any cells. It's still available from dealers about £350

[@mabjawaid]

No didn't need to replace cells. I'm not qualified electrician was worried KZbin may remove video if showed whatbI did with that.

[@nicmic6269]

It's your mistake. The rear door lift supports are new, but the brackets attached with the screws are very rusty. You probably bought aftermarket lift supports, and reused the original mounting system. When you reassembled the old gaskets, they allowed water to enter. This is what happens when you skimp on small jobs, you always pay more.

It's the weld seams too

Interesting I have the same issue with my Lexus RX 400h I'm told that the battery is dead because of a lot of water there. Did you change the battery and or what other parts did you get?

@@mabjawaid thanks for the info. How did you know that the battery and the fans were okay?

[@mabjawaid]

Sorry late reply didn't know they were there. The car charges battery it self. Just replaced control unit nothing else

@@mabjawaidyeah unfortunately I had to get a new battery which was expensive but comes with a 18 month warranty.

[@fiernanluvall]

This just started happening to mine this week😢 What a horrible design flaw!! Did you do everything yourself? Or just the prep work and have a certified electrician swap the control unit? Class action lawsuit anyone??

[@mabjawaid]

Did my self had motor electrician check it and was there when I sealed battery.

[@logankdavis27]

Do you have a part number?

[@mabjawaid]

Hi think it is G3840-48010

[@mabjawaid]

That is the main relay for battery
