When i bring the car to a stop, or accelerate and even turning I can hear a liquid noise, like water moving around from under the car on the passanger side. Seems like its coming from under the dashboard area, could this be the A/C condensation leaking somewhere into the car?

 

can we get a little more discription on the sound?

ie: water in a big plastic drum or vodka in a metal shaker ...

there are lots of liquid noises ... i dont think i've ever heard any (form the car) myself, but maybe with more discription we can figure it out

 

its quite common with the IS300, happened to me once before, its from air bubbles in the coolant system.....fill up and top off your coolant!

 

ah i was wondering what that was! i havent heard it for a while but when i first got the car and would start it up it kinda sounded like a toilet flushing just not as loud hahaha

 

lol! ive heard that noise a few times

 

went on my.is and found numerous threads about the same sound, and everyone says its air in the coolent system. But ya did does sound like water moving around in a bottle i guess. I just bought the car on sat. and already have had this problem and a problem when i keep my foot on the break pedal at a dead stop, i get a hissing noise like air is leaking from around the break pedal area...does this count as a lemon car?

 

awesome sound for sure
