Prius (Gen 1) :: 2002 Pinging Under Acceleration And Sounds Like Something Metallic Is Rattling
I'm having a problem with my Prius. It pings under acceleration and it sounds like something metallic is rattling. It only happens when I use 87 and 89 oct. I use 91 premium to reduce the ping however, gas prices are rising and I want to go back to 87. There are no warning lights or anything and the ping has been happening for quite some time now.

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.
Lexus GX 2004-09 :: Metallic Rattling Noise Going Over A Rapid Series Of Bumps
My truck is making a metal on metal rattling noise when going over undulations or the type of vibration when you drive over a rumble strip.
It seems to be coming from underneath the engine area, but not quite sure. The sound is like a kettle lid clanking on the actual kettle when the water's boiling if you can hear what I mean. No noise when just driving.
Prius (2010-12) :: Metallic Rattling Noise Coming From Transmission When Switched To N
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 back with another question! My 2006 Prius now has 60,XXX miles and the other day while driving with the windows down, I was climbing a hill to my house and when the engine is at a certain RPM, there is a metallic sound that comes from under the car, but more in the front. You can't even hear it when the windows are up barley, but more when they are down, you can hear it, especially when you're beside a wall or guard rail and the sound can reverberate back.
View 2 RepliesPassat (B5) :: Metallic Chime And Rattling Noise?
I am a brand new VW owner and new member of this site. Just recently I purchased a '02 Passat GLX 4motion (w/97k miles) for fairly good price knowing that it was involved in a rear end accident.
Now I am finding multiple issues with this car. It looks excellent from exterior or interior. I have three different issues (front and rear axle pinion seal leak, broken spring, gas leak only when tank is full) with this car but I would like to discuss the Broken Spring issue here.
When I go through rough road or bumps I hear a metallic noise (noise like key chiming) from the rear driver side along with a rattling noise (like wood or plastic board rattling) at the same time from the rear middle part of the car. I researched online and found few forums talking about the brake pad caliper spring making similar noises. I called a mechanic and I was told that it could be the muffler.
I took the wheel off and kicked and hit the axle area with rubber mallet, kicked the muffler - but no similar noise was produced. However I noticed that the spring coil (rear driver side) was broken right at the bottom. When I did online research I saw one forum talking about broken spring making similar noise. I did more research and found the part (OEM# 4B0 511 115 B).
My question is:
> Does this sound like what causing the noise? Could a broken spring cause metallic chime and a hard board rattling noise?
> Is it necessary to replace the spring along with the shock absorber? Can spring be replaced by itself?
> How hard is it to replace a spring?
> Do you have to have spring compressor to mount and unmount? Can you simply take the whole assembly without compressing it?
Prius (2010-12) :: 2013 - Squealing / Rattling Noise During Acceleration
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.
View 19 RepliesSubaru - Legacy :: 1999 - Metallic Rattling Noise
My '99 Legacy is far from quiet, but yesterday I heard a new -- and somewhat alarming -- noise.
Roughly two-thirds of the way through a four-hour drive, I started to hear a rattling or grinding sound coming from the front of the car, perhaps closer to the driver's side than the passenger's. It sounded as if a tin soup can or paint can were hitting the road, but when I popped my head under the car, nothing was hanging loose.
I hear the rattling sound as I begin to accelerate, and only when I have my foot on the gas -- when I let off, it's perfectly quiet. What I haven't been able to determine is whether the noise goes away after I reach a higher speed, or whether the sound of the usually loud engine drowns it out. The noise is most acute around 1500-2000 rpm whether it's in gear, or whether it's in neutral and I'm revving the engine.
Prius (2010-12) :: Slightly Shaking Engine - Rattling Noise On Acceleration?
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.
Golf V R32 :: Metallic Scraping / Rattling Noise Coming From Underneath The Car
My R32 has got about 9,400mi on it, and for the past 3k miles or so, i've been dealing with this metallic scraping/rattling noise coming from underneath the car. When I took it to the dealer, they said it was the exhaust flex pipe, so they replaced it under warranty. Next day after picking the car up, same noise. So i took it in again this morning and they are saying its the flex pipe again, and they don't know if it is fixable.
They are talking to VW tech assistance, and trying to figure something out. I really love this car, but if VW says there is no fix for it, I'm weary about possible future issues without fixes too. Apparently it has something to do with the length of the flex pipes and the material its made out of. He was saying one possible solution is stiffer engine mounts. We'll see where this goes.
Toyota - Prius :: 2004 - Catalytic Converter Rattling Under Heavy Acceleration
Toyota says the code is P0420 and the Catalytic Converter is rattling under heavy acceleration showing the Catalytic converter is bad and should be replaced. Toyota wants 2,334.00 which seems very high to me. Is it the Catalytic converter? The car is a 2004 Toyota Prius.
View 12 RepliesPrius V :: Engine Ping (rattling Metallic Sound) Under Load
When accelerating up a steep grade the engine will ping (rattling metallic sound) when reaching a certain RPM, but stop pinging as I continue to push the accelerator down and increase the RPM. Should I be concerned? Could it be something else, loose exhaust heat shield or something? Or is this normal behavior for a gasoline engine? My old Honda Fit never had engine ping/knock that i can recall in its 200,000km of service running the same 87 octane gas.
View 15 RepliesPrius (2004-09) :: Metallic Noise At The Top Of Engine When It Is Engaged
Our 04 Prius makes a really scary metallic noise at the top of the engine when it is engaged. All maintenance has been performed within 100 miles of the warning light. We are the original owners and the car has 160k miles. No pulleys are touching their surroundings. Make no mistake, this a LOUD noise that has been growing with time. No warning lights,,,oil level is fine,,,and no metal visible on the dipstick. Sound is originating at the top of the engine and is not a "knock". It is more of a metal on metal type of noise.
View 4 RepliesFord Ranger / B-Series :: Rattling Noise Sometimes Kind Of Metallic Ping From Rear End
1988 Ranger, 2.9, 5 speed, 2wd, 7.5, 3.42:1, 190K or 290K on the odo.
I've been hearing this rattling, sometimes kind of a metallic ping, from the rear the last week. I thought it was probably the universal joints, didn't do it often, only under load between 1500-1900RPM roughly in second, third and fourth. I planned on working on it this weekend.
Today it started really making noise, sounds like valves rattling as though the timing was too high but it was coming from the rear end. It was making it all the way through the gears into fifth, even when cruising. Once it cooled down a bit it nearly went away.
I'm going to get started on it as soon as I can, but I can't get it in the shop to pull the differential cover and take a look right now. Dad's shop is full of crap, I live on top of a hill, not many safe places to get one up in the air properly. What is causing that sound?
Prius (2004-09) :: Metallic Rubbing Noise In Left Rear
First the specs: 2008 w/38K, not sure which package but nothing fancy. This morning got in the car and started off and hear a metallic rubbing noise coming from the left rear of the car. Sounded like it came from around the wheel area. Temp was coolish around 36 degrees. The noise only happened for the first few minutes and only when going real slow, like 5 or 10 mph, and only when I was turning right.
Sound was like the the sound you get when a brake pad is worn way down and scrubbing on a rotor or drum. Also, the sound would speed up as I sped up until a certain speed then would go away. I actually stopped and restarted to be sure I could make it happen again. Once the car warmed up I couldn't reproduce the noise. Drove the car later in the afternoon with temps in the high 40s and no noise. Also, I never use the E brake so can't imagine that would have any impact
Ford - Ranger :: 1998 - Metallic Drivetrain Noise Only Upon Acceleration
The vehicle in question is a 1998 Ford Ranger XLT with the 3.0L 6cyl engine and an automatic transmission.I've done quite a number of repairs already and am now trying to isolate what might be causing this particular noise.
The noise itself sounds a little bit like a rotational metal on metal sound with a dash of two washers being vibrated together. It takes no effort at all to reproduce; put the car into drive and step on the gas. The truck will happily move forward, making that drivetrain sound.
Here's the thing..
1) If you're in park and step on the gas, there's no sound.
2) If you're in neutral and step on the gas, there's no sound.
3) If you let off the gas and coast, the sound goes away immediately. Step on the gas again, and it comes right back.
To me, this seems to indicate a motor and transmission mount problem. If the engine is idling, then it isn't spinning the drive axle or rear diff.Upon acceleration, the driveline might be torquing strangely and this in turn would cause the differential yoke to spin at an odd angle causing the noise. It'd also explain why all the noise ceases when I let up on the gas; there's no more load on the drivetrain.
I don't believe it's the axle or pinion or even wheel bearings, since the car is -quite- quiet once you let up on the gas pedal...
Tiguan :: Light Rattling Noise During Acceleration?
Noticed a light rattling noise during acceleration? It only seems to do it at lower rpms then stops? I feel like I remember reading something about the wastegate causing this? but I don't remember where i saw that?
View 24 RepliesPrius (2004-09) :: Rattling Noise Near Water Pump / Pulley
My wife calls me yesterday and said she could hear a rattling noise from the engine area, but no other issues presented themselves. Later, I checked the engine compartment for the noise with the engine on and found that the noise was coming from the area of the engine water pump/idler pulley but i couldn't really narrow it much closer. The noise honestly sounds like bearings about to go out. I did see that behind the water pump pulley there was a small buildup of corrosion on the water pump, but no apparent leaks or wetness. The car has the original water pump and idler pulley with 140k. I plan on replacing the water pump, idler pulley and thermostat in the morning. Or is this overkill? I don't want to lose the engine nor do I want my wife to get stranded anywhere.
View 9 RepliesCamry :: 2002 2.4L - Engine Rattling Noise On Acceleration
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?
