Prius C :: 2012 - Low Speed And Cold Start Vibration
Jun 9, 2014
I recently took my car to the dealer as it is under warranty, 25000 miles on it... (I used to be a Toyota tech a while ago)
after a cold soak, the gas engine starts, but its very shaky, almost like a miss-fire. And at about 10-20mph when you go to accelerate lightly, to make the gas engine start, it starts vibrating again. but if you give it more gas, it smoothens out. Still sounds like a misfire to me...
But, there are no codes.
The dealer replaced all 4 injectors, performed a throttle body service, and an EFI Service, includes, fuel system cleaning, tank additive.
they told me the injectors for #1 and # 2 where not performing correctly and that they needed to be replaced. after opening a case with the infamous TAS (Toyota tech support)..

When I start the car and its cold outside the car is shaking like a leaf for about 1 minute and when I arrive at 3000rpm there is like a vibration in the steering and in the pedals.

I'm experiencing vibration somewhere under the hood during start. I recently replaced the serp. belt and think it could be over-tensioned.
Possible?
Dangerous?
Or just the new belt needs to stretch?

I found recently that my 04' Prius' engine easily goes higher rev than before (based on engine sound pitch). It happens mainly when cold start, go up hill. After warmed up and on flat road, it goes back to normal. Overall, still in great condition at 211K. MPG stays at 46 on meter when temp is around 45F with 50% highway drive at 100 miles/day. I suspect the serpentine belt slippery or something. What do you think? I think the belt is original. I bought it used at 104K.

I have a 2012 camry se v6, with about 56k miles. It has been lowered on H&R springs since 20k miles. I recently got new rims, but used my old tires. I developed a high speed vibration. I got it aligned twice, and balance twice. But i still can not get rid of this vibration?

My 2012 Kia suffered a "catastophic failure" of its transmission about 10K miles. It was replaced, I got a rental, all covered by warranty. Last month I noticed a vibration as I rounded a tight curve at high-ish speed (DC beltway). It felt like mu left front tire was going to fall off. But it came and went. two weeks later, again, vibrating and now I'm noticing it is associated with acceleration. Boyfriend in passenger side says it feels like Right rear wheel, I still feel like it's left front. Next day I drive to Virginia beach and almost turn around, the whole car is shuddering on acceleration at low speeds. I hit 95 and it settles down, but I took it in to dealer as soon as I returned.
Dealer couldn't find anything, so they rotated and rebalanced tires. I drove it home, no problem. Parked it for 2 weeks while I drove my other car. Next time I drive, vibration is back. This time dealer drives it, agrees it feels vibration, couldn't find a cause, but maybe it's debris on axle. Cleaned wheel wells, axles etc. Drove home no problem. Next day, vibration is back. Every time I accelerate it feels like I'm going to drop an axle, when I ease up, it decreases. Worse on curves. At constant speed, no vibration. I don't want to take it in again unless I can point these guys in the right direction. I really want to just give the car back and say give me another one.

2007 Prius has Kumho Solus KR21(all four) tires installed 2 years ago - about 3 weeks ago had the tires rotated as well since they had about 5K on them.

Couple months ago I noticed that my car was experiencing rough idle, stuttering exhaust note during cold start. RPM is very stable!
Forward 4-5 months to last week, starting to notice vibration and it seems like the situation has gotten worse. The car returns to normal after 1 minute or so depending on how long it has been sitting there for. For example, If I park there for 30 minutes and try to start the car, I can feel a little vibration for up to 10 seconds. If it was parked for overnight, then the problem lasts up to one minute and then clears out. Now it's throwing a P0302 error which is cylinder 2 misfiring.
It's really like magic, the car would idle pretty rough and suddenly clears out.
I put in 4 brand new ignition coils and plugs, all OEM stuff and still hasn't worked.
This problems started during the winter time and I can clearly notice it's gotten worse and finally last week it threw the misfiring code.
I feel like something is failing or building up slowly. My car is a 2009 GTI TSI which has the same engine as the MK6 GTI.

My Prius v has 1300 miles. I didn't notice at first but now I notice a constant high frequency vibration in the car, especially at highway speeds. Took car to a tire shop and had tires dynamically balanced, same problem. I think it must be the toyo low profile tires or its in the drive train and just inherent to the hybrid system. Seems to be the same whether in eco mode or ev. Vibration is the same on smooth or rough roads. Dealer service manager says he is not aware of any problems. Suggests bring car in for a test drive and compare with another new one.

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?

Had my JoeZ exhaust installed at my first oil change at the dealership about a month ago.
Anyway, late last week I noticed on cold start in the morning I'm getting a metallic vibration noise. This is on gentle acceleration out of my subdivision. It disappears within a minute or less and doesn't re-occur until the next morning. Best way I can describe the sound is a cell phone set to vibrate sitting on an aluminum cookie sheet.
Any hints on what I can check that might be the culprit? I already checked to see if the muffler tips are hitting the exhaust diffusers but they're clearing and I can reach up around the canisters and fit my hand up around them so they're not touching that silver heat shield material.

98k miles and if the car is on a slight incline and your backing up or creeping forward it feels like you are going over a rumble strip. that slight stuttering feeling. no codes have tripped. I've asked the toyota dealership and they don't know what could be the problem. The trans axle fluid was changed at 88k and from what i was told there were no metal shavings in the fluid. it was a little dark but after going 88k miles i assume it would be.

I've had my 2010 GTI for 8 months now and have really only had one issue with it. When I start the car, it shakes before I start moving. Like, the steering wheel, body, pedals, gearshift, etc... It's not a violent shake, but definitely something I've never noticed in any other car I've owned including my MkV GTI. It doesn't seem like a normal feeling for a brand new car. I took it back to my original dealer at 4,000 miles and they said there was nothing wrong with it and they didn't feel any vibrations.
Well lately it's been vibrating more intensely and more often (at almost 8,000 miles) It now does the same thing while stopped in traffic or at lights. It's really annoying to me. I took it a couple days ago to a new dealer (I moved) and just talked to them on the phone. They also said there's nothing wrong with it and it's normal.
I forget exactly what they said it was because I was walking to the gym, but basically it was some cooling pump/fan that kicks on to cool the engine down and that's what is causing the vibration. But, they said it's normal and all VWs do it. I'm not quite sure why a fan needs to cool a perfectly cold engine in the morning though.

Bought my 2006, V6, about 2 months ago. This morning was the first really cold once since I bought the care. When I started it today, the idle speed was about 1200 RPM. It took a few minutes to warm up and then the idle speed dropped to normal. Quick question. Is this normal?

Since having my engine replaced with a newer used engine block my idle speed when I first start it up or when it is cold is around 2000rpm which lasts for about 2-3 minutes until it begins to fall to the normal range of 1200-1400 and finally to 850 or 900rpm when warm. how can I fix this or is it okay to idle at 2000rpm for a couple of minutes? is it hurting anything?

I purchased a second hand 2000 Prius for my wife about a year ago and the car has been awesome. A few months ago she started experiencing a steering vibration only at low speed when cold and steering wheel turned sharply.
It got worse till you could feel a slight vibration when even going straight, I tried to scan the OBDII for faults but my scanner would not even work on the Prius.
I search online and bought a U380 OBDII scanner but since it would take a while to get to me I decided to disconnect the 12v to reset the computer (and fix my map lights while disconnected) when I reconnected the 12v the car started ran for about 10 seconds then cut out with the red triangle showing. I thought maybe I had done something wrong and the immobilizer had cut the engine, went inside to check my manual I had bought(cd version) on my computer and google search but found nothing.
Went out and disconnected the battery again and reconnected with same results. After some more searching went to car and it started right up no triangle. Here is the strange part, for the next several days the steering was great no shake at all and even the slight vibration was gone. Over the next few weeks it has slowly been coming back again but still not near as bad as it was, I finally got my scanner and scanned it but it shows no codes. I have not seen anywhere if successfully repaired this type of problem without replacing the whole steering rack but maybe I am missing something, anyway I have a couple of questions in my quest not to replace the rack.
1) Is it possible that it has the zero adjust error and my scanner is not reading it?
2) My repair manual(although it does not seem very good) shows resistors with some kind of contacts in with the torque sensors, is it possible these contacts just need cleaning?

I just bought a used 2012 pip with 26000 miles. I noticed that when I accelerate at the on ramp to reach the carpool lane, a noticeable vibration is felt from the front end of the car. The vibration subsides when I reach cruising speed. The steering wheel doesn't shake or vibrate, only the front end. I checked the tires and they look fine, they are the original tires that came with the car.

I'd like to stay in EV mode when driving my sons to school, but we live on top of a hill, and with a full charge, no matter what speed I go down that hill, the ICE always comes on. I've tried braking to limit my speed to 35 mph or 45 mph or just coasting, in which case I get up to 53 mph. It's usually about 60 degrees out and I don't use seat heaters or A/C. Is there anything I can do to stay in EV? I'm guessing the battery gets too full from the coasting and/or braking on the first half of the downhill and that's why it switches the ICE on halfway down. I sometimes wonder if I should use the timer to prevent the battery from charging up all the way...or just drive around the block a few times before going down the hill to "free up some space" in the battery for the energy I will get going down.

I have a 2012 Camry Hybrid 4 cylinder. I like the car but it has a knock on cold start. I have around 12000 mi on the car. I noticed the knock after a few months of ownership. It does not do it every time. Usually happens after sitting overnight and in colder weather. I live in Minnesota so it gets cold. The car is always garaged. It started as a knock for around 15-20 seconds. Now it seems to be more frequent and lasts for a longer duration, but it eventually smooths out and runs fine. The noise does not sound good. Sounds like there is no oil in the motor and it vibrates and shakes some until it finally smooths out. I just think this sound should not be from a Toyota, with its advanced engine design.
