Prius (2010-12) :: Slightly Shaking Engine - Rattling Noise On Acceleration?
Jul 7, 2016
Slightly shaking engine and rattling noise on acceleration,it happens when the car is hot and especially when the battery level is very low ,I guess is when as more load . If I accelerate and keep it steady at 20mph I can feel a constant vibration but goes away once accelerating more....like if you're driving on a rippled surface ....that is only when engine is on , doesn't happen on electric only.
The noise it sound like a tapping coming from the engine when slowly accelerating from 0 that goes away as soon I give more gas ,is annoying wile in the traffic.? Can the sparks plugs be the problem?they been changed 120k ago.....,I cleaned the egv pipe but problem still there. Like I said is only when the engine is up to running temperature.

2013 Prius 3 making a squealing or rattling noise when accelerating after car is warmed up. It only does it when the car is up to temperature and when you accelerate slightly harder, like going up a hill or something. It sounds like a pulley or something squealing. It has been to the dealer and of course they couldn't duplicate the noise or see anything wrong. Not to sound funny, but it actually sounds like a hamster running on a wheel. It is very annoying. It is not a constant noise, it only happens under load. It gets louder when the ac is on as well. If you let off the accelerator when it starts the noise goes away. I don't know of it matters but our car has the forged 17" wheels on it from the factory, and the car has 8600 miles on it.

i have been hearing a rattling noise coming from the engine under acceleration only. It isn't a super consistent rattle, seems to only happen when accelerating from lower speeds. And sometimes you don't hear and other times you do. It's not a bad rattle or knock it's more of a ticking/light rattling sound that is definitely abnormal.
I know my brake accumulator is barking at me and the 3 way coolant valve is going bad as sometimes I get a constant pumping sound. I don't think these have anything to do with it but thought I'd mention it.

At first it was leaking coolant very slowly,then making the rattling engine noise at low rpm then a part flew off while on the highway gushing out oil. Time for a new used engine. Planning on diy if all else fails off the junker. 230,000 miles on odo.

I got in the car today and started it... I was waiting a few seconds for someone to get in the car (it was in the garage) and as soon as the engine kicked on there was a very very large long rattle noise i immediately turned the car off. Waited again and turned it on same noise.. the only thing I found was a cover under the car towards the front was really loose. ( I haven't hit bottom or anything while driving) but I did have the lighted door sills just installed the other day. But it never made that noise..
btw i have 1100 miles on it..I looked under it and is the black dust protector thing supposed to be loose like if I push on it I can make it rattle..

My Camry has about 338K miles. Started making an engine rattling noise on acceleration. suspected worn timing components. I have all timing components off now. Of course plastic chain guides are worn, tensioner plunger seemed to be a little rough in actuation, exhaust cam sprocket does show signs of wear. I dont know for certain that replacing all timing components will clear noise. Questions are: considering mileage should i just replace all the timing components or the likely cause of the rattle noise(whatever that may be)? Should i replace the oil pump while i have pan off? How much trouble would it be to pull head and do valve job at this point? Lastly....2002 Camry has the 2.4 VVTI with the intake cam sprocket. How do i replace this sprocket and is it difficult?

While driving through a tunnel today I noticed a metallic rattling noise upon acceleration. It goes away immediately when I let me foot off the gas and when I park the car and rev the engine the sound does not occur.
A few days ago, I had to rapidly accelerate and it felt as though I lost power for a split second. I am not sure if these are related, but I am hoping its not some sort of transmission issue (unless that is covered under the hybrid warranty. What was the diagnosis?

On a handful of occasions, when I start my 450H, there is a noticeable vibration that lasts a few minutes and goes away. It's usually happened on really cold days in Texas. This morning, it was very warm, it didn't vibrate but made some click sounds for several minutes. I'm still under warranty...

My 2010 Prius engine shakes/vibrates when the engine is showing between 50-75 MPG on the gauge/meter on the dashboard. There is no vibration when coasting (100 MPG on the gauge/meter on dashboard) or when I am accelerating pretty modestly. Only when accelerating very softly. It started a month or so after I had my spark plugs replaced at 133K miles last June 2015. It has gotten progressively worse. It is especially noticeable once the engine is warm or the outside temperature is warm. During the winter months the vibration was there slightly, but not nearly as noticeable as it is becoming now that warmer weather is here.

So i'm only a week and a half into owning my Elantra, 800km on it and today when i started the engine i noticed a clicking/rattling sound, like the noise when someone sticks a piece of paper into a fan. Anyway it's quite minimal and you could hear it louder when you accelerate. I never noticed it before, even when i test drove the vehicle.

The past week I drove the 1800miles. This afternoon I went out, pushed power button, get out and clean windshield off and ICE turns on with this clunk clunk noise, shook the car like a sob too. Checked oil and it showed a clear metallic gray/Black tint with end the light tan oil.

I have a mk7 with 12k miles on it (edit: Manual). I noticed this noise periodically and it is hard to reproduce. I haven't been to the dealer yet because we all know how that intermittent noise thing goes with them.
Symptoms: Accelerating (usually 2nd or 3rd) low rpms. If I am going slightly up hill it will make a sound like a metal ball bearing inside of an Altoids can. "Tack Tack Tack.' It doesn't happen all the time and sometimes the volume varies. I'd say it has happened to me 10 times in the last 2 months. It appears to be boost related as it is building.

So at 19+K I notice the car has tire noise and shakes. Take car in for 20000 mile service and the dealer tells me I have cupped tires. They say the car must be out of alignment to get cupped tires. I think not because the car goes straight down the road. They have nothing to offer in regards to getting new tires free or adjustment on new. I should have pushed hard for a resolution to the problem right then and there but did not. I rack up miles fast so I put up with the problem and at 37000 have the dealer put on new tires and check the alignment. Alignment was in specs but not to complete center. So I have them align the car.
On the way home I notice I still have a shake, felt in the floor and the passenger side head rest shakes back and forth. They rebalance the tires and tell me all fixed. I drive off only to feel the same shake.
I go back and insist on talking with the service manager. Take him for a ride and he can't feel the problem and says all he feels is the normal Prius road roughness. He says if I leave the car they will check it out further the next day. I tell him maybe the reason my first set of tires went bad is due to the shake. Look further than the tires! Next day when I pick up the car they tell me they road forced balance the tires and let air out of the tires to soften the ride.
Of course the car still shakes. I take the car to a different dealer and tell them I need the car completely checked out and not to focus just on the tires. They tell me the tires where way under inflated and out of balance, one even by one and a half ounce. They tell me all is fine. I drive off and still it shakes. Go back and take the tech for a ride. He can't feel the problem.
So got a shake in the floor that is best felt at between 65 -72 miles per hour? How do I correct this? If this is normal for a Prius why did I not feel it for the first 19000 miles? I say it must be drive train related but I can't seem to get people to not focus on the tires. Car is 15 months old and I closing in on 40,000.

I've noticed that when accelerating from a stop and turning onto an adjacent street to the left or right, there seems to be stuttering or shaking coming from the engine. I'm usually in ECO and only 1/3 of the way into the "engine half" zone on the HSI. It's not consistent but has become a bit of an annoyance.

Once in awhile, as in maybe once a month or every few thousand miles, I hear a rattling noise in the rear below the car. It is very audible and everyone in the car notice it.
This happen only when I have been in traffic for awhile during which:
1) when battery is running really low from moving at low speed
2) After which the engine is turned on to charge the battery
3) moving low speed with the engine running.
The vibrating noise increases as my speed increase, getting more audible and vibrating faster. After a certain point (maybe 30 mph) the noise stopped.

I have a 2010 Prius 2 with 58K. A few weeks ago, mainly when turning right, my car makes a strange sound on the driver side (never on the passenger side). This noise is not very loud and almost sounds like two chains hitting. It usually makes this noise when I turn, but not every time I turn, and it usually happens when I first start driving.

I have a 2002 jeep liberty 3.7... It auto trans 4wheel drive. All at once it makes rattling noise and shake like crazy. I was thinking oh no another u joint but checked them none broke or cracked. So I got back in drove it on home and it had stopped. So then I thought front cv axle. So I put in 4x4 and drove it and nothing?

Anyway, so a little over a year ago I had to have my head gasket replaced and when I picked it up they told me I had a cracked motor mount. After having just spent an exorbitant amount and being poor, I decided to wait to fix that. It seemed to run fine so I didn't worry about it too much. Sometime last year I started hearing this rattling noise when I pushed the gas. It would start and then die off. But it didn't do it all the time.
Fast forward to the past month or so and I've started to get vibration and shaking, usually between 60-70 mph. Thinking it was my tires, I took it in to have them balanced. It rode smooth after that for a few days and came back. The rattling noise has also become more prominent and is pretty constant now. I took it back to the shop and they told me it was more than likely the motor mount. So I went ahead and had that fixed today.
When I picked it up it seemed fine. The noise seemed gone and it rode smooth. But as I drove home and got on the interstate everything came back and sounds/feels just as bad as before. What gives???

One thing that brought me here is the noise of my liftgate when being closed. When the liftgate contacts the latch it makes a rattle-y/loose sound. The trunk is locked and secure however the sound is very off-putting. I bought my 2010 Prius II as a CPO last year and never really thought much about the noise, only that it didn't sound very pretty.
However, I was recently sideswiped and was put in a 2013 Prius II and the liftgate closes with a solid thunk with no loose rattles. What could be causing this squeaky/rattle sound? I thought it could be my license plate frame since rentals typically don't use frames, but it seems really unlikely.

Noticed a weird metallic rattling noise coming from the transmission when switched to N with the engine running and the car is stationary? Almost like the gears are rattling inside while in N position. I took it to the dealer and their Prius guru said this is normal characteristic of eCVT....

I'm having a trouble when accelerating at low rpm the engine begins to rattle. Tried removing the connector plug on the egr, to my surprise the rattle is gone but the engine light comes on saying that the EGR circuit is incomplete. Took it to the dealer and they diagnosed it to be the EGR valve opening but failing to close, so they instead proposed to fill in gas with a bottle of their injector cleaner. That made no difference, so tried replacing the EGR valve but again makes no difference. What could the culprit be?
