#139 of 148 regarding the loud fluttering and shaking
Oct 26, 2010 (9:01 am)
tkethumper, I have not had this happen again. The dealer service never found anything wrong. Just prior to this happening to me in March, I had twice turned the car on, moved it a short distance before the gas engine turned on and turned the car off. As I hit the power button to turn it off both times, the gas engine started to kick in for a fraction of a second. (I was backing the car out of the garage in the morning and back in garage in the afternoon.) I told the dealer this and they thought the car should be designed to handle this. But the Field Technical Specialist did mention "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."
So I am wondering did you (or anyone else that experienced this issue) previously shut the car off just as the engine was turning on?

Yes. I was visiting my dad for the weekend. I parked the car Friday night, then got up Saturday and had to move it to the end of the driveway so he could get his car out. I didn't touch it again until Sunday morning when I started it up to drive 3 hours home. When I moved it down the driveway (about 15-20ft) the gas enginer either didn't come on or just came on when I shut it off. However, I've done this before and never had an issue like this. Maybe it was just that exact timing like you mentioned. It hasn't happened since and has been running smooth. I've been careful since to only shut it off when the gas engine has been running or I'm in full electric mode.
I appreciate the response. I'm relieved to hear that it hasn't happened again. I've been going back and forth all week about whether or not to trade this in and get a new car before it becomes a major issue. I love the car and have had no problems other than this and the dealer putting a gash in my leather seat during a service visit(which they replaced free of charge). Hopefully we've discovered what causes it and can avoid it now. A scary lesson, but nevertheless, a lesson learned.

Very interesting that you also just had the car on for a short time with the gas engine perhaps just starting up when you turned it off. That sounds like the common item. Like you I am careful not to shut it off until the engine has turned on and been running at least 5 seconds. This seems like a corner case that Toyota didn't test fully; I wish they could reproduce it so others wouldn't have the same problem.

Very happy (not really though) to see that I am not the only one with this issue; and like some of you have experienced, Toyota service techs still are unable to provide a reason or solution as of this writing. I currently have my vehicle at the dealership and will get them to watch the video. However, it is really unnerving to see after these many years they have not found a definitive cause given its clear chain of events. Push the break in, push the power button, wait for the ICE to kick in and then bang there is your noise. It seems like such a small area to inquire into? However, I guess I would like to say that in my case the video was essentially identical to the noise and steps taken in video; however, I did let the car run a little longer and the thunking sound bogged down to where the car almost sputtered off, but then quickly started to rev back up which the thunking also did as well until the point where the engine started running like normal and the noise stopped. I then smelled kind of a gasoline/smoke scent in the cabin and saw a little white smoke go out my tailpipe, much like you would see if you overchoked a lawnmower/tractor. So there may be some validity to the gas injector theory mentioned earlier. However, with such a violent thunk/shake of the vehicle it has to be causing harm to something which will most likely lead to costly repair or leaving a loved one stranded somewhere someday. I'd like to get a list or number of folks that have experienced this same issue (I believe I saw approximately 570 people have viewed the You Tube video) and take this issue up the food chain a little further as I feel this really is not an acceptable operation quirk. Thank you for your posts and would appreciate any further insight or possible remedy.

ikaikamute, I originally reported this issue here back almost exactly a year ago and posted the video on YouTube. Since then my wife said it briefly happened once (where it started shaking after the ICE kicked in). Based on what the service department recommended, she planned to let it run instead of shutting it off, however it went away after a couple seconds and then the car seemed fine.
ikaikamute, It sounds like you let it run and got more symptoms. Had you previously started the car only to shut it off just before or just after the ICE kicked in? This seems to be a common item between my case and at least one other reported in this forum. Besides you and I, I counted three others that reported the issue: user "mcast" had it happen a couple times, "rover13" reported it once, and "tkethumper" reported it once and also had previously shut off car quickly. Also possibly a fourth on YouTube, user "diggitydo41" said they had the same issue.

Thanks for the post and for the video pdxsk8!! I am going through this exact thing right now and could not believe there was a video on it. After reading the thread I wanted to post that last night i moved my car from the driveway into the garage and then this afternoon the noise exactly like the video. That seems to be a link possibly?
I have not tried starting it again since reading this and letting it run. I am going to wait until my husband gets home so i can video this with the hood open like pdxsk8 had wanted to do.
Thanks to all who took the time to post about this issue. Even if it does start to run smooth, I think this will be something I will be nervous about until they know exactly what it is.

What a coincidence. I had to have my waterpump replaced yesterday on my 2007 TKH. It just so happens I have had 5 occasions on which the same violent shaking has occurred with my vehicle. The toyota people swear this is the first time they ever heard of such a problem and no one can explain what the cause is. Thanks very much to all who captured the video of this obvious defect. Now I have some better tools to demonstrate to the dealer what is happening.

As added followup to your post (kingstril and ikaikamute) the violent shaking demonstrated on my 2007 camry hybrid was first observed upon turning off the engine after running the vehicle. The subsequent occurances were all upon starting or with a start and rapid shut down.
One question for both of you. Have either observed numerous occurances of engine not being ready (shift to park first message) if you go through sequence too fast. My unit seems to require a very deliberate slow sequence of brake on, push start button, wait 1-2 seconds, shift out of park. Any deviance/simultaneous action/ or failure to wait causes warning message.

Note, I found another video on youtube with the same issue. www.youtube.com/watch?v=zRY7eHgOJTc . It seems there IS a pattern here. So how do we get Toyota to address the issue? For now just don't shut the car off until after the ICE has been on for at least 30 seconds.

Just wanted to know if you ever got this issue resolved. I am having the same problem. Service dept. says they have not seen it before, the panel is rivet in so should not be a problem. At the time I went in, parts from overseas were in short supply and not soon coming because of the earthquake and tsunami.
I've considered using strips of felt to cushion the filter, but thought I'd ask first.
Thanks for your input.
