Prius (2004-09) :: Ticking / Rattle Under Light Acceleration
Aug 13, 2015
I have a slight ticking/rattle noise under light acceleration. When I get on the on ramp and start accelerating as the rpms go up there is a sweet spot at lower rpm where you can hear it rattle and as the rpms increase it suddenly stops. Its not tied directly to the RPM, but seems to be harmonic or related to a certain frequency. I haven't been able to recreate it in the parking lot. Water pump seems ok, no visible leakage. Hasn't thrown any codes and doesn't sound like pinging/bad gas.

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.

My 2005 Prius has always made a light ticking noise whenever the blower air fan is on. It adjust noise and speed when adjusting air speed.
I have replaced the cabin filter with no luck. It almost sounds like a leaf or paper, but I can't see or reach anything in there to fix it.
Is there a DIY write up to remove the blower? I suppose I will see if there is anything to clear out, or potentially just replace the unit.

I have the classic ticking sound on acceleration. I had a muffler shop check it out and the tech said he thinks the passenger side exhaust manifold has a leak. I have already replaced the whole manifold and cat on the drivers side. Could it be just the gasket? The ticking is coming from the top near the engine and not the cat. Is it a pain to replace the gasket?

2013 Elantra manual. 60,xxxkm, owned from new, purchased in August 2013. Oil changes always done within 5-7000km. Was 2000km over my oil change due date when this happened (haven't had time to get it done, been driving my motorcycle mostly). Driving around today I dropped my wife off, then I heard a quiet ticking noise under very light acceleration.
The noise would go away under normal acceleration, no noise while revving, and no noise while engine braking. The noise got worse after about 5km. I was in traffic and engaged the clutch into first gear, the car stalled violently. Turning the key results in a click, then nothing. In 1st gear the car will not roll forward. In reverse the car will not roll back. It still rolls in neutral. Had it towed to my local Hyundai dealer and got a rental. Waiting on the results.
Never saw a drop of oil on the ground while parked, and never smelt any oil burning. I run between 87 and 91 octane, whichever is available. I have the extended 160,000km 8yr warranty, hopefully this is covered as I still owe about 15g's on the car.

2004 Buick Century. 3100 motor. 150k miles... Recently discovered strange noise but not sure exactly how long its been happening. (I listen to the radio pretty loud)
Engine sounds normal at start/idle (hot and cold). During acceleration I hear a constant ticking/tapping/clattering at a decent volume from 1st to 3rd..after 3rd it quiets down a bit but still constant. It goes away completely directly after shifting into 4th. I then cruise down the highway at 75-80 with no problem whatsoever.(It can also be heard if i rev the engine in park.)
The day I noticed it i immediately checked the oil. It was a little over a quart low. I filled it but the sound has not changed.
I wouldn't say its a full on knock but it does sound alarming like the engine could blow at any moment from 1st to 4th. Sounds perfectly fine after that.

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?

Just bought a 2004 with 240000 on it. Yesterday it started accelerating roughly. Today did the same and the traction control light came on and off several times. And just half hour ago I drove it about 10 minutes in town and the check engine light came on and stayed on.

I just got my wife a 2000 Echo with 224,000kms on the odo. Everything appears to be fine other than a mystery rattling noise under light acceleration. If I were to describe it, it sounds as if a box of rocks were to be shaken around. Or like a rattling loose chain... <------ definitely hope it's not that!
From a search, it seems like others have encountered this strange noise but have not reach what the cause is.
From what I gather, the timing chains on these motors are literally never touched and should last the life of the vehicle.

I have a 2004 Camry with what is the most odd noise I've ever heard. The noise sounds like a cross between water trickling over stones and maybe bearings rolling around in a tube, or maybe someone crinkling paper. It sounds like it is coming from inside the dashboard, or maybe just beyond the firewall in the engine compartment.
It tends to occur when the vehicle is stopped and is just starting to accelerate from a stop. It can also occur when the vehicle is breaking to a stop. It doesn't sound like break pads (not grinding metal-on-metal sound).
At a stop, I can shift the automatic transmission into neutral and rev the engine a little and the sound will occur, but it doesn't seem to be dependent on any specific RPM nor does it co-vary based on increases or decreases in RPM. Basically, when I rev, the sound simply occurs. It is of variable intensity and duration, and is very random in peak of volume and sequence of noises. If I didn't know better, I'd swear there was a chipmunk under the hood (I looked, there isn't.)
I drive the car daily, but my regular trip to work is very short so the car runs for no more than 5 minutes each morning. In a five minute drive, with 4 stop sign/lights, the noise will occur basically every time I accelerate.

I have a rattle of some sort I can hear coming from underneath towards the rear while under acceleration. Usually hear mostly at certain RPM and not through entire accel to hwy speed. Do not hear it while in Park and reving engine, but on the road I hear it. Mostly I think after it gets hot or something.
No driveability issue only rattle? While I was reving in Park I could hear a bubbling after I let off the pedal. Is that normal. I don't think it is the same noise/rattle.

We have a 2007 Prius and have been very happy with it overall. The right rear tail light keeps burning out and we keep taking it back to the local Toyota dealer for replacement, but they have been very good about it. Though an annoyance, if that was the only problem we had I would not be here right now typing this.
Today my wife was driving and came to an intersection at a red light to make a right-hand turn. She braked coming into the turn and as she made the turn. What happened next scared her and is very concerning to us -

So I got a new rattle that I cannot find the source of. It's definitely coming from around/above the pedals. For some reason you only hear it when your cruising around 60. It doesn't increase with speed. It actually sounds more like a ticking. I've tightened the plastic guard above the pedals and the dead pedal with no results.

I have a rattle/ticking noise that happens when the 05 Phaeton experiences road vibration. I'm thinking about taking it apart to see what may be loose. This is the console between the two front seats.
I've narrowed it down by placing my hand on top to silence. It can't be silenced by touching the rear seat vents or power plug cover. So it seems the whole console must vibrate to create the noise.

2004 Prius with 109,000 miles. It's been in an accident before (and you can tell, the front right fender is a bit misaligned and the doors have a paint covering abrasions).
However, the car is making a ticking noise every minutes or so. The sound is originating in the Hybrid Synergy Drive converter inverter box and about every minute for about 5 or 7 seconds or so there will be a ticking or clicking noise. This happens when the car is idling, driving, and even a minute or two after car was shut off. The mechanic next door to the dealer didn't know what it is and the dealer is giving me a 30 day. What could this clicking be?

I've got an '04 Pkg IX with about 68k miles on it.
I've noticed that at speeds of greater than 60mph there is a distinct ticking noise (like the sound a bicycle makes when you turn the wheel "tick tick tick"). The noise is coming from the front end, sounds like near the passenger area.
The minute you drop down to speeds of around 50 or less it goes away.
I'm probably going to have to take it in to the dealer since I've already had an indy look at it.

I have a 2004 Prius that has a ticking noise coming from the engine compartment It speeds up and slows down with the idle of the engine or the pressing of the accelerator. Appears to be coming from the passenger side (US). No diagnostic codes have come up.

Exhaust tick really bad under acceleration when its cold. It goes away after the car is really warm. Im thinking i have an exhaust leak that is closing up when the exhaust warms up.

I am getting a ticking noise under hard acceleration. Dealer told me the exhaust is touching the heat shield but did nothing about it. It's driving me crazy...
I may have to pull the trigger on this Borla I found for 700 shipped and new. Trying to keep my promise to myself to drive the car stock for a year b4 any major spending. That's out, I can already tell.

My son's 2010 Toyota Corolla S made a "rattling ticking sound at idle" twice this week.
I can't duplicate it, the oil level is fine and everything is working.
