Seriously,
I know it sounds weird. But occasionally when braking and sometimes after the car shuts off and the brakes, for lack of a better term, "power down"
It sounds like air being released. Truly like a fart. Sounds like a joke, but I swear its not lol.
Anybody had or heard of this problem? I just had the EGR replacement done (luckily they extended the warranty so that was free). Seemed to start after that
but I'm betting its just a coincidence.
Any suggestions to solve this problem would be great. Its kind of embarrassing when there is a passenger in the car. lolol

Its a 2012 CT with 117,000 miles. Otherwise still runs/drives perfect other than the occasional brake clicks that I've read so much about that I've decided to ignore it.

Thanks!!!!

I have the same issue going on in my ct200h. Did you find out the issue? What did you do to fix it? Thanks!

It may be the actuator, which is subject to a recall.

I know on my IS300 that the noise was in relation to improperly lubricated brake pads.
