Hello everyone,

I have this weird some coming from the rc f. just started happening today. sounds like its coming from the rear or under the seat.
really hard to hear it from the video... (have to turn up a bit to hear it in the background). its a bit louder in person. maybe the fuel pump?
thanks anyone in advance

I took mine in. The noise was not always present. The dealer, Lexus of Rockville said they had to hear it. I told them they could sit in the back seat on my trip to Florida from MD and Uber back. They choose to take my word.

So far, no noise but big side benefit, NO hesitation down shifting now. Car runs much better.

Took it in to the dealer yesterday. They said it was a software error they had to update with the fuel pump (no idea what). Took about three hours.

Most of us that got the reflash done noticed an improvement with the shifting of the car when you go from a cruising speed to really getting on it. There use to be an annoying delay of some sorts. Te reflash really helped

No power seats in mine.

3:30 AM at my mother-in-laws, got up to go to the bathroom like always at this time, decided to check on our baby as this is the furthest we've taken it, and heard this sound. I crawled up underneath in my pj's and it sounded like it's coming from this module in up behind the spare tire, where the tire chain comes down. It kept this up for maybe a few minutes, got a little higher in pitch in sound, came back to how it was originally, then abruptly stopped. Anyone know what it was or what it could be? Almost sounded like a compressor?
