FYI: Noise when Vehicle Stability Control Engages by baylie

I have noticed my 2007 camry making a loud "Thunk" noise in the mornings when I first start off or the car has sat for a little while.
 
I took it in to my dealer and the only solution we could determine was the VSC engages at about 10-12 mph or 20 feet. The rest of the time it is not that loud.
 
Has anyone else heard this noise?
 
I have also noticed like pickles007 that when I take my foot off the gas quickly the car seems to skip a gear and drastically slow down . I do not notice it every time, but I am hoping as the car gets more miles this will get better or I will again be talking with my service department.
 
Otherwise I love this Car
 
Gertrude is a LOADED V6 / XLE.
 
I love driving her and cannot wait to go on a road trip this weekend to see how she does on the open road.

I have a thunk as well, first thing in the morning. LE 4 cyl w/VSC, just over 800 miles. Was just starting to try and figure out where it was coming from. Appears to come from the drivers side front. Thought at first that it was first time the brakes were applied (like the caliper/brake pad was sticking), but don't think that is the case. I back out of the garage every morning, and was going to try backing in at night and just pulling straight out in Drive to see if the symptoms changed. The engine is idling fast since it's cold (about 1500), which potentially might be related as well. I suspect the idle speed will drop once the engine is completely broken in.

Kiawah
 
Sounds like the same noise.
 
When I fill out my customer survey I will list this noise as something I think they can improve upon.
 
Muffle the "THUNK" from the VSC.

"...To my knowledge, the new transmissions are built by Aisin in Japan..."
 
Has this been verified? Have previous Toyota A/Ts been produced by Aisen? (I was under the impression that Toyota designed and built their A/Ts in house - and even supplied Volvo at one time.)

I don't think its the VSC, but rather, ABS. All vehicles equipped with ABS do a system self test within the first several dozen feet of vehicle travel. Its very noticeable on my Sentra, and I believe it may be what you are hearing with the Camry. Can non-VSC equipped Camry owners confirm?
 
Is it really a "woe"? Geez.

No, it isn't a woe.
 
People just don't understand how things work.

Well it may be as designed, but I've had and driven many cars all with ABS for years, and have never heard a clunk like this before from any ABS system. I'd personally be surprised if it turns out to be ABS related, but we'll do some more problem determination.

I used to hear a noise when my ABS-equipped 1990 Mercury Sable's system did the self-test at startup.
 
But my '97, '04, and '05 Camrys (all with ABS but no VSC) made/make no such noise (at least that I can hear).
 
But check your owner's manual, because I think it mentions this for both ABS and VSC.
 
About idle speeds, a cold start idle at 1500 rpm is nothing to be concerned about. That's pretty typical of fuel-injected cars these days.

I can't remember exactly which system is causing it, but my Quest did it and my '05 Odyssey does it. The service managers at both dealerships assurred me that it was normal.

Nor do my '04 Highlander or '05 Camry, both with VSC. Typical ABS self-check is the motor/pump coming on for a second or two, sounding more like a buzz. I'm not sure what would cause a "thunk."
