RX450H strange voice
Just bought a 2019 160000kms (100000miles) Lexus RX450H. There is a very loud screaming sound coming from the engine (only when the engine on) - when i drive in EV mode the sound disappears.
The strange thing this sound quites down at 40-50kmh (30mph).
It sounds like a Prius 3 electric water pump.
All the fluids are at top.
I had 2 RX450H from this year and neither got this issue.
Anyone knows what can it be?
