Gas Tank Slosh Noises, normal?

Has anyone noticed that when the gas tank is full, it makes an audible sloshing noise when coming to a stop or going into a parking lot ramp. For a few days, I thought that something was loose in the rear suspension or trunk, then realized it was the fluid in the gas tank. Of course, I generally notice it only when the radio is off or low and I'm performing the above tasks and the ICE isn't running.

Can others confirm if they notice it too? Just want to be sure it's "normal".

Finally, does the PiP still use that Gas tank bladder like in the 2nd gen prius?

 

Yeah, I've got to believe it's normal (I remember my 08 Touring having a slight noise, but it seems louder on my 14), but I'd like to know if others have noticed it as loudly.

When I realized it was the gas, it was only after the car came to a stop you hear a slight noise in the back, then a second or two LATER (after the car has already stopped), you hear an additional slosh/bang (well, more like a light thump) noise in the back (like water hitting the side of a bowl, since that's probably what's happening).

 

Whew, that's a relief. I don't live in a cold climate, so the bladder issue in the 2nd Gen didn't affect me, but it's one less thing to worry about.

But then I'm thinking w/o that inflatable bladder, that might be why I hear the sloshing sound more? Plus when the tank was half full, I heard it less too, maybe as it gets to the top, the liquid is closer to the seating area, so you hear more of the movements.

 

yeah, no rain

I drove again today to run some errands, no radio, no ICE, no AC, stopped abruptly and heard a slight sloshing noise, seems to come right from the bottom of the rear seat (where the gas tank is). The tank is full too, but at about half, I don't think I notice it as much.

 

It'd be great if someone could full tank it, then drive around and see if they notice the sloshing noise after abruptly stopping.

I looked at some old posts on priuschat and it seems like others have noticed it before on then 2nd gen Prius (also when the tank is full), otherwise I suspect when it's close to half or empty, you're not going to notice it as much. I can just turn up the radio too... the car is just SOOO quiet, you tend to hear everything. Especially running in plug in power only (which I've spent the past 3 days doing, 80 miles, all plug in), I kind of forget what the engine sounds like!

 

Truly

Truly! Also, the time it's going to save by not having to get gas as often can't be measured.

 

Thanks for confirming everyone!
