Hi I bought RX450h

[Abdul chaudhry]

I have recently bought the car and I has developed a fault on high rev’s it comes up check hybrid and check AWD and others and car stops the error code is comes up as crankshaft sensor voltage too high 

crankshaft sensor was replaced by Lexus in Feb this year and help in this  regard will be very helpful 

I was advised the ECU harness loom needs replacing 

[Bluemarlin]

How recently?

If it was from a dealer I'd take iit back to them to diagnose and fix.

It was in February this year

Who advised you?

Didn't Lexus do a scan of error codes when they replaced the sensor?

If they suggested the loom needs replacing did they say why it needs replacing?

So legally you should have cover for any major defects for 6-months, take it back to the dealer to fix or refund, don't throw money at it.

Go to your local Citizens Advice or Trading Standards if the dealer does not play ball.

Actually I bought the car recently and the previous owner told me all the in formation and I have invoice from Lexus 

I rang them and they said the car was fixed and In February and the owner did not come back to us and now they will charge again to diagnose the car

Did you buy the car from a dealer or private?

[Abdul chaudhry]

I bought it privately and the owner told me that there was a problem on high exceleration the EML comes on it only happens on a hill at high speed

Caveat emptor. But now it's done I think your only action is to take it back to Lexus for proper fault diagnosis. You have no come back on the vendor if it was a declared issue and you still agreed to proceed with the purchase. Good luck.

was the issue resolved in the end?
