GURGLING/RATTLING NOISE AFTER COLD START

[MAReed]

Hi - just bought a 2019 RX450h a few weeks ago. Just after cold start up when the petrol engine kicks in, I hear a soft gurgling/ soft rattling noise which appears to come from just behind the middle of the front seats and under the vehicle. This tends to disappear when the engine has warmed up. I took it back to  Lexus Bolton and asked for this to be looked into. I was informed that this was NORMAL and was the fuel transfer pump. Has anyone else experienced this. Seems to be a strange normal thing for a premium quality vehicle. I have not had this on my previous NX vehicles.

I haven't noticed it on my 2019 rx

Nothing like that on my 2018.
