Thanks for the video. About two months ago, my 2007 Hybrid Camry made exactly the same sounds and was shaking. It did that when the gas engine started in the morning. I turned off the car, considered my options, and started the car again. It worked fine and has been fine since then. But that metal-on-metal chattering was not a sound easy to forget. And the shaking suggested the car was suffering a calamity.
I love the car. It is smooth and quiet. I think it is a brilliant invention. But the fact that you could make a video of exactly what happened with my car makes me think there is a problem that I hope Toyota will help us fix.

Interesting several others have experienced the same loud fluttering I did. The dealer service never found the problem. They forwarded my video to a Toyota Field Technical Specialist and he said something like "there is a flexible coupling between the trans axle and the engine, and when you stop the vehicle right when the engine comes on, the injectors are still spraying fuel in there and it can do what you are talking about." The FTS had the service dept do "a couple tests on it" but apparently nothing came back out of the ordinary so they had me pick it up.
I have been driving it for just about 2 weeks now and the issue has not returned, but my wife doesn't want to drive it and I keep wondering if and when it will resurface.
I have considered trying another service center (there are a few different Toyota dealers around here), but wonder if it is worth the hassle. Is there anyone at Toyota we should contact?
#131 of 148 Engine Oil

The TCH is supposed to use zero weight oil. Is it possible that a heavier weight oil is the source of the unusual sound ?

I highly doubt that, the noise and vibration is external to the engine itself. I have blown a few engines in my time, they don't make that kind of noise once, and then run quiet.

How do you know it's external to the engine ?

That's easy, the noise it made, if it were internal, there would be parts sticking out of the block by now. Any engine that makes that kind of noise, will never run quiet again if it was internal. Like I said, I blew a few motors in my time, and worked on them for a living for quite a few years, you get attuned to certain sounds. Besides, the second part, the vibration that accompanied the noise, engines that make noise on start up, don't vibrate, they clatter, or blow apart, but never do they make noise and vibrate, then start up and run smooth afterwards, it is just not possible. My guess is an issue between the ICE and the electric motor used to spin up the ICE, if one is out of phase with the other, it can do exactly what was described.

Lets suppose the noise was due to a heavier weight oil. As the engine heats up, the oil becomes more viscous and the engine now runs fine. Where do, you get your oil changed ?

We've gotten the oil changed at the dealer every time. We've taken it in for all recommended service in the manual.
Someone else told me they thought it could be "the starter" (although not knowing exactly how the engine starts in the hybrid) and the explanation that pat85 has of "an issue between the ICE and the electric motor used to spin up the ICE" sounds the most plausible to me right now.

I was just wondering if you've ever had a resolution on this. I just had this happen to me on Sunday. I have a 2008 Camry Hybrid. I just had the 5,000 mile service done last week and have always done everything on time, at the dealer. Car has 42,000 miles on it. I took it to the dealer yesterday morning and played your video for them to show them what it sounded like. The mechanic got it on the lift and saw that the water pump was leaking coolant. Since they couldn't replicate the sound (it's been fine since making the noise) they said that the faulty water pump could have caused the noise. They replaced it under the powertrain warranty at no charge. I'm not convinced that it was caused by a water pump. I'm of the opinion that the water pump was damaged by the engine shaking violently.
I know it's been a while since you posted this, but if you get this and have had this happen since or ever found out what was wrong, please let me know. I drive a lot for work and now I'm afraid that I'll end up stranded somewhere in a car that is supposed to be one of the most reliable out there. Let me know, thanks.

I saw that video and responded that I had exactly the same experience with my 2007 Camry Hybrid. I am happy to tell you that the problem has not yet occurred again. I would be even happier if Toyota would tell us what causes the problem.
