I recently acquired a 2003 Camry with 150,000mi. its has a rough take off from stop and when I accelerate it make a rattling/grinding sound. the sound disapates after around 30mph. Ive changed trannyfluid, oil change next is plugs and all that good stuff since I do not know when it was done last.
View 4 RepliesI have a 2001 Camry LE, 4 cyl, 2.2 liter, automatic transmission, 163Kmiles on it.
I'm hearing what sounds to me rather like a grindy sound at around 1400-1600 RPM. Initially the Camry seemed to do it only after getting into 2nd gear at about 10MPH, but now i see that it is associated with RPM and not the gear so much (the noise is less frequent and less loud in 2nd and 3rd gear- not noticing it ever at above that). I should say that the Camry has been making lots of noises since a new exhaust was put in by a cheap Bosnian shop.
It seems to only make that particular grindy noise when starting from a dead stop, but not if i was already coasting at all. So far as i can tell it seems to only happen about half the time- if I'm accelerating very slowly it doesn't seem to happen much. If i start climbing a hill after a dead stop it seems to come on fairly reliably.
It does not seem to make the noise when passing down through 1600 RPM while slowing down or revving down.
When i started the Camry up today, the noise cropped up well before i got to 8MPH (where it typically shifts into 2nd gear). Which is to say the noise appeared before it even started to shift out of 1st gear.
If i stay in Drive or Reverse and apply the brake so as to not go anywhere, the noise generally starts around 1600RPM. Since the car isn't moving, i think this might rule out the transmission. I hope.
However when in Neutral or Park and i bring the engine up to 1600RPM and beyond, the noise does not appear. So that's perhaps not so good. Of course my car idles a lot better/smoother in N and P than it does in D or R. It's rather rough idling in D and R.
I'm hoping maybe it's a vibration issue- something like harmonic amplification- where something only rattles in a certain frequency range. I pulled up next to a brick wall, kept on the brake, went into D and got up near 1600RPM and the reflected noise does strike me more now as maybe being less a grindy noise and more of a rattly vibration.
The Bosnian shop who fixed up my exhaust were too quick to dismiss the noises i heard after they worked on it. I think maybe something is loose. I hope. (I could feel air leaving the flexpipe's woven area itself but don't know if this is normal.)
Going up hills increases the likelihood of the noise appearing (so i take this to be suggestive that it IS the transmission).
However on a flat road if i hit the gas to quickly get up to 1600RPM before I'm any where near auto shifting out of 1st gear, the noise also usually appears (so i take this to be suggestive that this is not the transmission). I've also gotten the noise to not appear until well into 2nd gear.
The fairly-repeatable noise appearing in the 1600RPM zone regardless of my gear position gives me some hope that the xmission is not the source of the noise. So on balance, i think there's some indication it's the transmission, but there's also evidence that the source is other than the transmission.
The noise does not occur in Neutral or Park while revving up to 1600RPM. But then too, the engine, exhaust and vibrations always seem considerably less in N or P, as opposed to being in Drive (or Reverse). Why my Camry is quieter and more smooth in N and P as opposed to D or R? In the latter two modes, i imagine the transmission is engaged? And that the transmission is unengaged in P and N? And would that make the car louder or vibrate more, at least under certain conditions? Is the engine under less load in P and N?
And are noises at certain RPMs in D or R, but not in P or N indicative of Transmission problems? I notice the shop overfilled the transmission fluid every time i've had it changed.
Recently I started hearing a rattling/grinding metallic sound coming off the right rear while driving slowly. This sound is not reproduced when braking.At first it started while doing sharp right turns only, now its ever present while driving. I showed it to a mechanic he says rotors needs to be replaced. Is he right? 2003 Honda Accord V6....
View 7 RepliesI've got an 03 Camry (211K mi.) with front and rear disk brakes. I have a pulsing/grinding sound from the rear brakes. I think the pulse is from the run-out of the disk/rotor. Took it to a Toyota dealership last year and they pulled apart, cleaned and lubricated the parking brake assemblies on both sides. Brakes ran quiet for about 3 months and then the noise came back. When the climate is dry, it makes all kinds of noise. When it's humid (above 80%) or raining it's quiet. It still stops good and there is no pulling to one side or another, so I figure my calipers aren't leaking.
I bought the car used a little over 3 years ago and don't know when the last brake job was done. I was going to replace the front and rear disks and pads and inspect the calipers for cracked cups or seals. I was talking to an old school mechanic and he said something about opening the bleeder line(s) when I compressed the cups or I'd damage the ABS control. I looked at my manual and it said nothing about this. I'm not looking to replace the ABS controller because of a silly mistake on my part. Looking for info about cracking the bleeder when compressing a caliper??
I told them that my car sometimes when I accelerate a knocking or rattling sound comes from underneath the hood. I asked them to check it. I told him it sounded exactly like an older car I had many years ago which was the result of bad gas or too low octane.
With my older car I added higher octane gas (89) and the sound went away. I had a 2011 Prius before and never had this problem and I get gas at the same gas station for years.
So the mechanic test drove my car and said they couldn't find anything wrong with it. So I'm stuck with the annoying rattling/knocking noise when I accelerate (which happens about half the time), but now I'm experiencing another problem.
A couple days later I drove to get dinner. One way it is about 7 miles. Almost the whole way the ICE would not turn off. I would be at stop light, wouldn't turn off. I pulse and glided, when I glided the ICE remained on. Take my foot off the gas at slow speeds, ICE still on.
Finally towards the last 1 or 2 miles it started going into EV when i let the foot off the gas. On the way back it ran normal. It's been close to a week now since I brought it in for service and I only had trouble one other time.
Well I have been hearing a rattling sound coming from my engine when I accelerate around 55-70 for a second and then coast. Once I start coasting I hear some type of rattle noise coming from the engine. I just got back from the dealer and was told that the mid-section to my exhaust was bad and it needs to be replaced. The part # is 28600-4z300. I looked it up and it costs $1400 now, but it is on sale for $1000. I am hoping that this will fix the issue I am running into right now.
This problem adds to the list of crap I have been through with this car starting at 4000 miles. First a blown timing chain blows my engine, then my car goes into the shop 4 different times over a month and a half for a overheating/coolant issue. Had to get the engine replaced because apparently my "NEW" re-manufactured engine was leaking coolant into my engine. Now only 2 months since that has been put in I need a new exhaust..
I just heard this noise today. It is right when i start the car in the morning. it is like a rattling noise, and it gets louder whenever i accelerate. But the thing is that after the car is warmed up, the noise is gone. is that normal? i checked the engine oil and it's close to full. and i cant see anythign wrong in my engine.
View 1 RepliesI have a 2008 Hyundai Sonata GLS 2.4L with 131,000 miles on it. When I accelerate from a stop, there is a buzzing/rattling/grinding noise coming from the engine bay of my car. It's really hard to describe, there is a definite buzzing sound, but also almost like there is a bolt rattling around and banging into things. This only happens for a couple of seconds. It also seems to be worse when I'm accelerating up hill. If I accelerate slowly from a stop, the noise does not occur, and it also does not occur if I accelerate while I'm already moving.

I've been having this odd sound occur while I accelerate - sort of like a grinding sound (about 7 seconds into the video). It might be a bit difficult to hear over the other sound coming from my car... It occurs a lot more frequently when it's cold, when I'm accelerating, and when I am turning while I accelerate.
Also, the more obvious noise that occurs throughout the entirety of the video just began today. It does not occur while I'm stopped and it began when I stepped on the brake a little harder than usual...
Recently blew the belt that runs the water pump, etc while on a vacation. Had to leave the car at a small mechanic in Winthrop, WA. He replaced the Water pump which had gone bad and the belt that shredded. The car ran beautifully for a week. Now there is this constant rattling sound coming from the water pump area. the link is a video with the sound. The sound will quicken as you accelerate. At cold start up it is usually not present then starts a couple of minutes in.

Since about 5000 km, I have had a knocking metal rattling sound happening when I accelerate up a hill or a slight incline. It has happened a few times on flat road as well just more prevalent on the uphill battles. Now I assumed it was jus something loose that was rattling since I installed a cold air intake and had installed hid lights(I thought the ballast was banging on something). I tried and tried to find the rattle but I had no success. I read up on here about other people suffering the same problem and that running higher octane gas would solve it well I tried 89 and it was still there just not as much and I recently started using 91 and its gone haven't heard it at all.
View 132 RepliesMine is 2010 gen 3 Prius. I bought it brand new and about 6,500 miles. From the beginning, I sometimes hear a grinding and rattling sound coming from the right passenger side. It is not from plastics. It is mechanical sound. But the problem is it does not happen all the time. So we were hesitant to go to dealer because they will never find it. But it got more frequent with cold weather.
Now, it does make rasping buzzing sound like a loose fan usually after I start a car in the morning and the heater is kicked in. I don't think it has something to do with fan because if I just run it itself in high speed, you cannot hear it. It is just some bad combination that makes this sound that makes you go crazy.
We are afraid that something big will happen after the warranty is over but as we expected the dealer said they do not hear the sound. The sound comes out in low accelerating and disappears in high accelerating. Now I really regret having bought Hybrid. It looks like the dealershop has no clue where to look at. I think the sound gets worse with the cold weather.
I've got a 02 Camry with a manual. In 5th gear, cruising on highway, there's a low grinding/ rattling noise. it doesn't do it if you try to accelerate, or if you have no throttle input at all, meaning it only makes the noise when trying to keep one speed, typically around 2000-2500 rpm. If i grab the shifter and apply pressure in any direction, the noise goes away. I've owned the car for 3 years now and its always done it, and hasn't gotten any worse or changed at all. I'm experiencing no performance issues and just chalked this up to gear noise, but recently read someone else was having same issue, and everyone was clamoring on about needing new bearings.
View 14 RepliesI have an '08 Camry purchased a week ago. When I accelerate rapidly and the rpm hits 3500 to 4000 I hear a metallic grinding noise. It is only while crossing this rpm range. Only on acceleration. I have had some luck replicating the grind and making it last longer by feathering the throttle and holding the rpm in this range. It does not happen at any other range and I can get it to happen in D or 4. Have not tried other gears. My thought is some sort of drive train issue but the dealer mechanic says maybe an engine mount or something else. Sounds too metallic to be a rubber mount to me.
View 2 RepliesI have just bought a 2000 Passat 30valve V6, from a dead stop when I accelerate it makes a weird "thud" sound and feeling under my feet, almost like when you have a broken tranny mount on a chevy. I have been told that it is the "TPS" or throttle body?? It does not do this shifting into any other gear.
View 2 RepliesMy air conditioning compressor is rattling and grinding. I am trying to determine if I need a whole new unit or just a clutch assy. I can say this, when running it's rattling, but when the clutch engages, it clears up.
Would I be right in assessing it's the clutch? 1998 250 5.4 .....
I'm still getting used to my prius and hybrids in general so there are a few things that I still don't know about them. But what what makes that cool whirring sound you hear when accelerate from a stop or coast? It's got a cool scientific buzz.
View 6 RepliesJust took my V6 03 XLE to a mechanic to change the timing belt, water pump, and spark plugs. Runs great, like it always did, and for the record I just got to about 80,000 miles a week or two ago.
One problem after I got this all done a couple of hours ago. Every time I try to accelerate from a complete stop there's this gurgling noise that sounds like it's coming from the inside of the dash or maybe under the dash.
It only happens as soon as I accelerate from a complete stop for about 2-3 seconds, and then it seems to go away.
I have a noise problem on my dashboard ( or i hear like that) There is a sound which is really annoying when i accelerate especially on rough road.
Noise comes from dashboard in my Hyundai Elantra - YouTube
I've had this '96 Dodge Caravan for just over a year now and suddenly I go to try and start it and it will almost start but then stop. All my dash comes on like it supposed to but when I turn my key it just stuggles and makes a grinding noise. The only thing i know is my common sense is saying if it makes grinding noise dont keep trying you'll make things worse.
