Hi

New RX450h owner (less than a month). I love the car, except, I was expecting a zen experience, and I'm mostly getting it, except it's marred by the occasional rattle creak.

Phase 1 - pretty much the week I bought the car, the front passenger door made noise at certain speeds, and on certain surfaces. This came and went, and I took it in to the dealer, who added some felt insulation around the door handle (they said).
Phase 2 - now, when I go over sharp bumps (think Botts' dots on the freeway), there's a rattle from the same area, and the occasional one from the dashboard and center console (approximate locations)

The rattle I'm talking about is not quite a rattle, more like a higher pitched papery creaking noise, hard to describe. It's not loud, I don't notice it when the stereo is playing, but otherwise the interior is so quiet, this noise becomes a bit jarring.

Any ideas? Should I just suck it up, considering it's quieter than anything else I've ridden in, rattle and all?

 

I had a similar sound coming from my 17 450h. Drove me crazy. Kind of a scratching, squeaking sound. Not all the time but a good bump would cause it. Hard to isolate where
it was coming from. Somewhere up front on the dash I thought. After MUCH searching (rearranging the glove and console contents etc), I discovered it was my sunglasses in the
upper sunglass holder. One of the arms was vibrating when I hit a bump and it rubbed against the plastic interior of the holder.

 

Discussed here. Roof railing problem.

I have a 2016 RX350... I notice when I go over bumps I often hear a creak or rattle in the rear... anyone have a problem like that? Dealer can fix? Common issue? I have another RX350 and I never hear this.. thanks!

 

I don't think it's common, but anything can break on any car at any time. Certainly take it to a dealer or a suspension/exhaust repair shop, but first make sure there isn't anything rolling around in any of the storage bins in the back.
