Camry :: 2007 - Engine Knock Rattle Noise In Gear / Brake Pressed And AC On
Feb 7, 2013
So my wifes 07 93k miles started to make a strange knock rattle noise. It sounds like the knock some on here have when the water pump was going out. It only happens when the car is on, in gear ( drive or reverse) brake pressed And AC ON. The engine begins to vibrate under the load and the rattle begins. Sounds like you its coming from behind the alternator under the valve cover. Once I place it park.... or turn the AC off it goes away. It idles fine. Quiet And Smooth. But once I place it year it comes back!!

There was a TSB for 2AR engine, Engine Knock/Rattle Noise at Cold Startup. My question is for those I4 camry owner, do you have these rattle sound when you start your vehicle at cold? I am not sure if mines have the same issue, but pretty sure is I can't find any differences between mine and this clip:

So should I take it to the dealer? Or it's normal?

I own a 2002 Camry XLE 4-cylinder with about 95,000 miles which is in excellent condition and well-maintained. Recently I began to hear a rattle, tapping or knocking sound apparently from the passenger side of the engine compartment (passengers agree with apparent location). It almost sounds like engine knocking, but the times it happens seem to rule that out. It could be some metal vibrating against something, but I can't hear it when I'm under the hood, and nothing appears loose. I've taken it to my trusted independent mechanic, but he couldn't duplicate the sound driving for 15-20 minutes on the freeway or see anything wrong when put on a lift. The sound doesn't occur all the time, of course; that'd be too easy.
The noise begins:
-after I've been driving 15 minutes or more
-after the car gets above 45-50 MPH, but when the noise finally begins, it will then occur down to as low as 30 MPH.
Last weekend I drove 1000 miles roundtrip on the freeway at 65-80 MPH; it didn't begin for 30 minutes, but continued most of the way to my destination (5.5 more hours), though it did seem to stop a few times. This week, my 20 minute drive to work, which has about 10 minutes on the freeway at 65, has not caused the noise to happen once.
Characteristics of the problem:
-the noise is not related to RPM; once it begins, it is about the same frequency and volume at 30 MPH as at 80 MPH
-it doesn't occur when in park or neutral and idling, even if the engine is revved, and even if the noise was just occurring on the freeway moments before
-it doesn't change when running over rough pavement or in turns
-it doesn't change when regular gas is replaced with premium (tried this last week to rule out engine knock, though the lack of RPM affecting it probably ruled that out already).
So it seems like it may be related to the speed of the car and perhaps the temperature of the engine or compartment. The hood latch appears to be holding tight with no play, the strut mounts were replaced 10K ago, and the wheel bearings check out fine.

Experienced this (Loud engine knock or rattle noise) regarding the service bulletin (T-SB-0010-12)? If so, did you take your vehicle in for service?

Requiring that the brake pedal be depressed in order to start the engine can be a nuisance, say if the driver is out of the vehicle and the passenger wants to start the engine to run the A/C, etc.
There is a workaround though. Press the engine start switch once to go into ACC mode, then press and hold it for 15 seconds and the engine will start without the brake pedal having to be pressed.

I have a 2007 Camry XLE with 30,000 miles on it purchased new.I stated it up the other day after setting all night it had a very loud knock in the engine I shut it off and had it towed to the dealership. They started it up and wanted to know what happened they said it sounded like a rod out. They keep it several days and ended up doing a top engine flush and then replaced the spark plugs. They said it was a carbon build up.I asked if they suggest any thing to keep this from happening and they said they do not recommend using any thing. I thought carbon deposits were supposed to be a thing of the past. Does this still happen.

bought my car in 2008 with 19k already on it certified used. fast forward to 2012 and 102,000 miles on it engine has a knock coming from the engine block. I purchased a warranty 7/100,000 mile. Did oil changes myself every 5k full synthetic. when the car developed a knock i noticed the engine oil was scary low. Since i got my car from the time i got it at 19k and i bought the 7/100,000 mile warranty on top of that.

I get this noise, AT TIMES, on cold starts which sounds similar to a knock. It lasts for maybe a couple of seconds at most. It's not the FI ticking that is generally always present. I see where other models (engines) have reported start up noise but nothing on the 460.

So I have searched about engine rattle/knock and I have found lots of results for cold starts but I haven't found it for the issue that I am having. I have a 2010 and anytime the battery is real low, around 2 bars and the ICE fires up to charge it, any time I give it a little throttle input, I get heavy valve rattling. It doesn't matter if its cold or hot, it does it as long as the battery is low. I never get this noise when battery is charged up, only when low. I have a link to the video below and you can see once I give it some input, it starts to sound like an old diesel tractor. Prius has close to 200K on the odometer and all my maintenance is up to date. Please turn the speakers up but the noise is right at 5 seconds in or so.

I have a high mileage Aviator - it currently has 162k+ ... I have owned it since 136k, and according to Lincoln's records the transmission was rebuilt/replaced shortly before that ... The truck has run well since we've owned it.
It has developed a noise that I originally thought was an engine problem (bottom end), but I got under it today and took a good listen and it sounds to me like it's coming from the top side of the transmission.
I recorded some sound: 4.6L dohc "rattle" from above transmission - YouTube .....

The front end of my Toyota Echo has been squealing but only when it's either in drive or in 2nd gear and only when the brake pedal is pressed, once I release the brake pedal it only squeals for a few seconds then once the car moves faster than 5 miles an hour it goes away.. I completely replaced the suspension late last year. I just replaced the belt a few minutes ago and it still does this. I noticed that when the car is off and in park, when I shake the car forward and backward I hear a slight squeal coming from the front. I think it might be the engine mounts and or the transmission mount. What could it be?

I have a 99 Toyota Camry and recently the breaklight has been coming on and off sporadically. I assumed I had done some damage to my E-break, as the other week I tried to back out with it on (cut me some slack, I just moved to PA after having only really driven in FL lol). I wasn't worried about it since I didn't notice any issues with my breaks, however the last few days I randomly have to press the pedal down almost to the floor to come to a full stop. There doesn't seem to be any consistency to this, sometimes it happens when the light is on but usually not. It does it both when I am stopped (causing me to move forward slightly till I depress it farther), sometimes when I am stopping normally, both when I'm going straight and right after turning, ect.
I checked my break fluid level and it is at the minimum line so I doubt that is the issue. I did some research and saw many saying that it was likely just air in the lines and that the system needed to be bled. But some also mentioned replacing the master cylinder so I wanted to see what response I might get on here (I don't know very much about cars myself).

My wife called and said her ES350 couldn't start. I told her to wait 5 minutes and tried again. It still wouldn't start.
So I went there and tried to start the car. My first try did not work either. I noticed that the brake pedal couldn't be pressed down. It was quite stiff. So I pressed hard on the brake pedal and tried again. This time it started. It has been working fine since then.

I've noticed a noise coming from the engine which sounds to me like the timing chain. Seems like the tensioner is keeping the chain a little loose while the RPM's are low. The rattle doesn't happen all the time; only when I let off the throttle or accelerate keeping the RPM's low.
This is just my guess that it's the timing chain. I had heard a similar rattle in my old I35 and I had to change the timing chain tensioner.
I'm going to check the engine oil level tomorrow morning. This 10,000 mile oil change is really starting to seem like a not so good idea! Right now I'm at 9950..

I have a 2007 Sonata, 2.4L 4cyl. and it is making some weird noise as of late. I have done some research and from what I have read it seems like it may be a bad engine mount. One thing to note is that the noise really only happens when the car is cold and hasn't warmed up yet or on a cold day.
Basically the best description is that the noise is a high-pitched rattle/vibration noise. The noise seems to match the vibrations of the engine but doesn't seem to get more intense if I rev the engine. The noise does get quieter if I put it in neutral but it is still there. The noise also happens even if the car is parked and off, and I do something like shut the door or trunk. I haven't gotten a chance to get in there and look under the hood myself to try...

I was wondering if this problem is the "Barking" noise that keeps coming up the search or is it another problem. I will include a link to the video down below.
To start off, the Prius is 2010 Prius II and has 120k miles on it. Great Car. Only other problem was AC compressor dying at 90k.
The chirping noise happens when the brake pedal is pressed and does not go away until the release the pedal. It makes the noise regardless of whether the car is on or off.
It makes the noise when the car is stopped and or when the mechanical brake engage at between 0 and 6 mph.
Noise does not occur when the brake switch is removed. Not valid solution since the brake lights will stay on. It does not affect the performance of braking.
Here is the link to the video .... .... ....

I recently bought a used 07 Camry le, it has about 56k miles on it. I noticed this steering knock/bump symptom since the first test drive and brushed it off since it was pretty faint. Now that I had some time to google it I'm pretty sure the symptom is what everyone describes here as the "intermediate shaft greasing fix"
My question is this:
Is this dangerous or detrimental to any parts? I plan to do the grease fix either myself or via a mechanic, but I don't have time this week. I've only had the car a week. Steers fine (and surprisingly well weighted for a Camry), bump/knock is felt when doing slow turns (i.e. parallel park or 90 degree) and sometimes when coming to a stop or taking off from a stop.

I just bought a 2007 Camry XLE V6 with push button start. When I push the button:
1. the gauges light up
2. I hear a loud motor (gear) noise
3. noise stops and the engine starts up like normal. No unusual sounds.
4. I push the button to stop the car and the still no noise -- engine shuts off as expected.
5. NOW, when I open the door, I hear the same motor (gear) noise I heard in #2....the engine is off at this time..

I am looking to purchase a 1993 Chrysler New Yorker and when I test drove it I noticed that every time the brake pedal was pushed a mechanical whirring noise was audible. This happened every time the brake was pushed whether the car was moving or not. The car brakes seemed to work fine and there were no other noises associated with normal brake problems. The noise seemed to come from inside the car. What that might be? Also, any other reasons to not buy a 93 New Yorker with about 115,000 miles on it for cheap?

I have a 2008 Ford Escape, and today I noticed that while backing out of my driveway (downhill) as I pressed the brake pedal it made this grinding noise, but when I got out of the car I looked through the tires and the rotors and pads were fine. I did not get a chance to check the inner side of the rotor or pad yet. What else could this noise be if it's not the brakes? It only makes this noise when I press the brake pedal which is why I thought it was the brakes.
