Prius (2010-12) :: Shuddering And Vibration When Starting Out
May 31, 2016
My 2010 Prius has starting to shudder and vibrate a bit on occasion when starting to accelerate as in stop and go traffic. It seems to happen mainly when the electric charge is low and the engine is on charging the battery and then I start to accelerate at the same time. It goes away once the speed in over 10mph. It happens occasionally, not every time. Never used to do this. Car has about 160k miles. Could it be a problem with the transmission device?

I have recently noticed a vibration that occurs at VERY low speed - such as below 0mph and 1mph, while just starting (or stopping).
The best way to describe this vibration is that it feels somewhat similar to going over a rumble-strip - but not quite so intense.
It only happens for a very short time while just starting off (or coming to a stop) - and then goes away. You almost have to try to make it happen. If I try to carefully control the increase of the car's speed, I can -sort of- extend the amount of time that this happens.
I certainly have to be on the 'look out' to notice this and attempt to make it happen to really identify it. Otherwise, (if I accelerate too quickly i.e.: normally) it just feels like a couple of bumps in the road.
I think I read on here somewhere something about a breakdown of the winding insulation that provides such an effect? Is there any straightforward way (perhaps with a scan gauge or other tool) to conclusively diagnose this?

In the past month I have had 4 instances (approx. once per week) of vehicle vibration/shuddering. The first time I thought for sure I had a flat tire and pulled over immediately and had a look at my tires. All was fine and I continued to drive with no further vibration.
My Prius v ( lowercase v for the Prius v wagon ) has 50,000 kilometers. Has had all required service at our local Toyota dealer. It has always been a pleasure to drive, smooth and quiet. Has only been on paved roads and the tires are in excellent condition.

I have a 2010 Prius Pkg 5 with around 71xxx miles. I usually drive it like a regular car on eco mode and get around 38mpg average but recently I've changed my style of driving where I accelerate to the desired speed limit, let go of the gas, then reapply and keep the mpg meter in between the middle eco line and before the pwr band. I've been able to average 44mpg this way, which is great!
However, what I've begin to notice now is that say if I'm traveling at say around 45mph and let go of the gas and re-apply, the engine starts to shudder as if it's not getting enough gas. Why this is happening? I also need new tires (215/45/17) but that doesn't have anything to do with this. I've owned this car since 30xxx miles and haven't done anything other than put gas and change the oil at the dealerships. Could putting 87 octane gas with up to10% ethanol have any effect on this?

I have a 2010 Explorer XLT that I bought in 8/2012 with 7,000 miles on it. I had had a problem with a groaning noise and slight vibration starting at 34 mph, under load. I don't hear the noise if I let off the gas at 34. I hear it a little past 35 or so and it doesn't seem to groan again until about 60 mph or so. I also have a feeling of the all wheel drive engaging when I back out of the driveway, put it in drive and turn the wheel slightly.
I took it to the dealer this week under warranty and he calls me today and says the tires are worn differently all around and that is causing the problem. He says the tires could be out as much as, or as little as 1/16 of an inch and that is what is causing the all wheel drive to catch and also the groaning noise. I understand what he is saying, but I can't believe that is the problem or more would have been written about it.
I asked the guys about rotating the tires and he said it would not matter, it would just take the problem from one end of the vehicle to the other. These tires are not worn like the truck is out of alignment, it is just normal wear. It now has about 21k on the odometer. What do you all think of this diagnoses? The guy says the PTU thinks it needs the all wheel drive and therefore engages it. This truck can also be manually put in 4 wheel drive by flipping the switch.

The engine starts with knocking, rattling, and vibration that lasts for about 5 seconds. It seems to be an intermittent, rare event. With nearly 250,000 Prius in the North American market and the onset of cooler weather, it is time to see how frequently this occurs.

I leased a 2015 Honda CR-V AWD LX on March 11, 2015. The following day I noticed a rough vibration/shuddering/chattering that appeared to be coming from the transmission when the rpms ranged between 1,000 and 2,000. The roughness was evident at any speed (mpgs) when the tachometer reading was between the previously stated range. The service technician reported feeling the same roughness, but noted that the problem was characteristic of the CRV with a CVT transmission. On Tuesday March 17, I went back to the dealer and discussed the problem with the service manager. He also stated that he was aware of that particular problem and that it was peculiar to the 2015 CRV with the CVT transmission. He took my car for a test drive and admitted feeling the chattering. It was also evident to me as I sat in the passenger’s seat. He then took out another new CRV and it too exhibited the same characteristics.

My 2000 f250 4x4 V10 5spd manual with LSD and 63k mi gets an intermittent but very strong vibration like a shuddering, growling, rumbling in 2WD. The 1st time it only lasted about 1 second. It had been making a swooshing noise that sounded like front left wheel bearing for several thousand miles before this, so i replaced bearing assembly even though it turned smoothly.
After that, It still made the exact same swooshing noise and after a couple miles at 45mph, it had the strong vibration/shudder that lasted about 3 seconds. I stopped and locked the hubs manually. The vibration happened again in a couple miles, so seems like it's not the needle bearings in front stub shafts or locking hubs. On that last occurrence, the vibe went on for 5 seconds, felt the same with clutch in, and went away only after truck slowed down to nearly a stop. I've driven it about 6 mi total since the 1st occurrence.
Front right Wheel bearings feel smooth. I unbolted the driveshaft support bearing and it spins smoothly. The front u-joint maybe had a tiny bit of play, all bolts tight. I didn't check the nuts for yokes, but it didn't look like yokes had any play. Drive shaft slip joint moves smoothly. No up-down play at pinion shaft input into rear diff and output from transfer case. Rear diff oil was full with a little bit of silvery sludge on the magnetic filler plug, maybe 1/10 of a cc, no metals slivers or chunks. I raised the rear wheels and ran 5th gear 2WD at idle (~30mph) and touched a 4' listening stick to the drivetrain components.
The only odd sounds were from the rear differential. It sounded like a bad bearing with random crunches and thuds mixed in with the normal whirring. Crunches and thuds were loudest at front of diff housing. I blocked one wheel and repeated in 3rd gear. You could hear noise like gears meshing (noisy spider gears? maybe was LSD clutches?). The differential was warm after 5-10 minutes, with the hottest area being about 3" from the front of diff, just before the housing widens.
So, I'm guessing the pinion bearing is bad and the intermittent shudder is the bearing race spinning in the case when bearing seizes.

Is it possible to get OUT of "P" without starting up the works? I need to move Prius about a couple feet in my garage in order to get my motorcycle out, in the past I've just put car into neutral, let handbrake off and leaned on the bumper but that doesn't seem possible with Prius.
Car was built November 09 and when I purchased it in September 2011 (22000 km) I found it had a replacement battery fitted. Thinking the charging circuit might be low I checked the voltage at the ciggi lighter socket and was surprised to see 14.6v. I came across a post here which mentioned the float voltage as 13.8V. At 14.6v the battery is well into the "gassing" area which makes me wonder if the original boiled dry. 14.6V is within Toyota's spec?

This morning when I started my 2010 (30k miles, still a baby) it started making an AWFUL sound that I guess I can only compare to a helicopter (THUDTHUDTHUDTHUD). It was practically shaking the car. I panicked, shut it off, and tried again a minute later, at which point it was fine. I googled this and checked other threads, but the car was never in motion and the rear battery vent is completely clear. It drove in fine to work.
It has been BRUTALLY cold for 2 weeks (up to -30 with wind chill) but last night was only -5 and it was a balmy 3 degrees this morning.

My 2010 has the intermittent noise when starting in the cold. Brought car to dealer with printout of the TSB from December and they will not repair it unless they duplicate the noise. Also I read about a rear motor mount to be replaced.

Yesterday I started my 2011 Prius, about 3 seconds later (Im guessing here) I pushed the A/C button, the engine started (at the same time), and I got this horrible grinding, clunking, bucking noise from under the hood. It lasted for about 5 seconds then stopped and everything was fine. Engine ran smooth, A/C was running. I turned off the A/C thinking that might be it and started it again, again everything ran smoothly. I pushed the start button the shut down the car, waited about 15 seconds, pushed it again, all normal, again with the A/C on. I put into drive and moved forward, allowed the engine to start, no problems. Smooth operation, everything normal.
I gather it'd be a good idea to take it in, but want to know how many "on-off cycles" until a problem is erased from memory. I did drive it last night (everything ran just fine) and went through 3 "cycles". What this could be? Bad fuel?? I have a 2011, with about 38k miles on it. This is the second Prius I've owned and have never had a problem before, let alone something like this.

I have a 2010 Prius with 100,000 miles. It has a vibration that starts at about 70-75 mph and gets much worse at higher speeds. The tires appear good with no unusual wear.

The noise seems routine. It happens when you get close to the car and open your door. I guess the car is anticipating that you will start the car soon and under the hood, some subtle mechanical noises occur. Just wondering what that noise is?

I have noticed in certain circumstances that the engine seems to be in a resonance where it is shaking noticeably and getting worse not better. It happens in two situations.
One is after gliding and slowing to make a turn (with the engine off). As I am exiting the turn and hit the gas the car shakes a lot for about a second or two, then smooths out.

About a month ago, I purchased my 2013 Prius Four. I've put on about 2,500 miles so far and recently started noticing when I start the car up, it is giving off a high pitched squeaking noise. This happens both when the car is using the electric battery and when I can feel the gas engine kick in. After about a minute or two, the noise goes away and doesn't come back.

My Scangauge is mounted on the dash just above the steering wheel. My last car, a Subaru Impreza had lots of room on the steering column. On the 2010 Prius it's very difficult to see when mounted there.
Cold weather is setting in and the glue on the velcro is starting to give out and the Gauge will soon fall. Where are you mounting them? How are you getting them to stick?

We've got a 2011 Prius with a little over 24k miles on it . For the last few months we've been having issues with it starting. First I thought the remote barriers were dying so I replaced them , I thought my wife might have been trying to start it incorrectly till the problem happened to me a few weeks ago. What happens is you try to start it (foot on brake, press power button) and all the warming lights pop up , radio turns on , navigation turns on but car doesn't start. This morning it happend just once , yesterday I had to try it maybe 10x before it finally started up. The dealership had it last Saturday and of course it started every time for them and they couldn't duplicate the problem , they also said they ran whatever tests they do on it and it didn't turn up a problem. FWIW we had the software recall update done in June.

Recently bought a 2010 Toyota Prius 1.8 and it was working very well. It used to display a message saying that the key battery is low. Then one day, the smart key stopped opening the door. After some reading on the forums, decided that the smart key battery might be really low, so used the mechanical key to get in and tried to start the car by placing the Toyota logo of the smart key on the power button. Since nothing happened, decided to replace the batteries anyways. After the replacement, tried again, but zip. The doors still won't unlock, and the proximity switch-on also is not working. Why? Is it an issue with the 12-v battery?

I have a Prius III 2011. I've had it for 10,000 miles and have had no problems at all. Yesterday, when I started the car, it made a loud rumbling and the engine shook, when it transitioned from the electric motor to the gas engine.
It did that several times when I restarted and then went away. The problem happened on the transition each time. Electric motor came on perfectly and then ten seconds later it was like an earth quake under the hood.
My dad watched the engine and said that it shook really hard. At first he thought it might be a fan belt but then he said it seemed more like water or something may have gotten into the gas tank and it was choking...

2010 Nissan rogue (42,500 miles) When the a/c is on and I'm stopped in traffic, with my foot on the brake the car shudders. There are times I feel like it will stall. I've had it to the dealer several times and they've told me the compressor puts a lot of strain on the engine. I have been in many other vehicles small and large and do not notice this.
