GMC - Sonoma :: 2000 - Rattling At Idle With AC On
Jul 10, 2014
I recently bought a 2000 Gmc Sonoma SLS and it's been a headache ever since. Ever since I got it, it's made this rattling sound that only occurs when I'm both idling and when the AC compressor is on. The sound is intermittent and sounds like something rattling against a large metal pan. Whenever I turn the AC off or pick up the RPMs, it stops like it was never there.My first thought was: belt tensioner. So I popped the hood and watched the tensioner at idle and it seems to be moving back & forth a lot more than I think it should, however, there's not much give at all when I push on the belt itself.

I have a 2012 Camry se with the 2.5, When I'm sitting at a red light or the car is in park with the ac is on I can hear an really annoying rattling coming from the car. I dont know what it can be and now it is doing it when the ac is off but not as bad. The only thing I have installed on my car is a cold air intake.

I just put on a magnaflow cat-back exhaust and sometimes when i idle i have a rattle and sometimes it will not rattle. I went under it and shook all around to see if anything was hitting but there was nothing i could see. What could it be?

I was experiencing a slight under hood rattle when ever the ICE would kick in at approximately idle. It would go away if the pedal was depressed beyond the point that the eco light would go off. After scouring the internet, no good answer came up. So I checked under the hood just to see what was going on. Simplest fix ever, the stick that props the hood open had become unsecured. Snapped it back into place and voila, back to normal.

Usually happens after car is warmed up. Rattles only while stopped and transmission still in drive. If I shift into Neutral or Park, rattling stops.
Last time I had a problem similar to this, dealer said it was a heat shield making the noise and they said they removed the heat shield (didn't specify what the heat shield was for.
Now I'm wondering if the heat shield was removed, what else this could be now...planning on taking it in in a few days.

I have a 2004 3.5 V6 that is making a rattling noise when the car is in idle and/or about 1rpm. Sometimes, for awhile now , it kind of screams when I first start it...but not all the time. I know this is a loaded question but what do you think it might be? The screaming noises don't happen all the time, like I said, and very rarely happen together but the rattling is happening a lot!

Lately I have been hearing a rattling noise from the bottom of my car, when it's in park I can barely hear it but I know its there, but when i put it in drive or reverse it gets worse. Could it be that the exhaust heat shield is loose? Or worse? I had my Tranny fluid flused at 142,000 mi i'm at 144,000.

Mileage:8500km
My car started giving a rattling sound when idle 2-3 months ago. If the rev's needle is at 800rpm that woody woodpecker sound comes from the backseats (or maybe not, it's hard to tell). I slightly press the gas pedal and the sound's gone.
I remember the car to be dead silent during the first months, like omg i can hear my heart beating.

I've noticed that my GTI seems to rattle (on and off) around 2000 RPM. Happens when I'm going downhill or through bumps often. But I can occasionally reproduce it in neutral as well.
Here's a video of the rattle: [URL] .....

When I am driving my elantra (engine warm), say I pull up to a red light or I am in a 'drive thru' my RPM's will go to under 500 and normally go under 400 which causes the whole car to shake and sound like it will stall. The car also has the issue with the Air Conditioning on that makes the vehicle have a deep rattling sound along with the very low idle which follows with my lights dimming or lightly flickering.

I have a 2005 Honda CR-V with about 97,000 miles on it. I recently noticed that there's a rattling sound when the car is idle but it disappear when driving. The noise can only heard outside. It is also intermittent. I just had the idler pulley/Belt Tensioner replaced a couple of days ago as a friend thought that was the issue. Car seems run normal, I don't notice any change in performance and no check engine or what so ever. I have a long drive coming up in a couple of weeks and I have no clue what could be going on.

So this is the second winter I've had my GX (a 2014 purchased in Nov. 2013).
With radio and other accessories turned off, there is a rattling/grating sound that is quite pronounced at/near idle, especially when cold. Sounds like a rapid PRAPP-PRAPP-PRAPP. This occurs when the vehicle is in Drive, but stopped. Occurs most often at within the first 5 minutes of operation....i.e. leaving the house or office, driving to the end of the street, hearing it at a stoplight or stopsign.
I've posted videos/recordings of it previously, which I have also shown to the dealer. The dealer said they could sort of reproduce, but could not diagnose it. I have tried to crane myself outside of the GX to listen to it, but from outside nothing seems to be amiss.
At first I was worried that it was engine knock/the car eating itself, but if that noise was representative of that, I think the car would be blowing smoke or dead by now. I have not noticed smoke, adverse effect on fuel economy or the noise at speed/under load, as you would expect if the engine were truly knocking. So I'm thinking it may be a fan, some type of underhood accessory, etc. that is the culprit. Sounds almost like a plastic component (fan, pulley, etc.) could be off kilter?? Something that more or less goes away after the engine has fully warmed up and the car has been driven for 10 mins or so.

i have an 07 jeep compass (only 52k miles). it was making a loud rattling noise (i liken the sound to the noise a penny or pebble makes when its sucked up a vacuum). I pulled off for gas last night and it just wouldn't turn back on. AAA was able to jump the battery and i was able to drive home. Now its dead again. i previously had an issue where the car was stalling when idle (only if it was in drive). I'm thinking the rattling, battery draining and stalling must all be connected.

I have a 2004 ford f150 5.4l v8 triton lariat and while at idle it has a ticking noise like this video
YouTube...
However I also have a rattling noise when decelerating at around 2000 rpms that sounds like a loose chain in a box. Not sure if its VCT sensor or cam phasers ...

I bought a 2002 f150 4x4 with a 4.6l. It has 250k miles on it. a couple days ago. It had no problems at all during the test drive or for the 150 miles home. Yesterday after it warmed up, the oil pressure dropped to 0 while at a red light and had a rattling noise. Not a knock but more of a rattle. I can't isolate where the rattle is coming from. Oil pressure comes back with just the slightest of increase Of RPM and seems To have plenty of power while driving. I had read to check the pressure manually but with the noise I sense there truly is a problem. the oil appears clear and is full. What I should be checking on this.

I have a 2000 Honda Civic, manual transmission with 91,000 miles. I have a rattle coming from the engine, that was there before and after the timing belt was changed. I just notice it more now after the timing belt was changed. The rattle sounds like a marble or nutin a metal container(cylinder?). I don't hear it with just revving the engine, only when the car is in gear...put a load on the engine. It increases in speed as the engine speed increases and is harder to hear or it disappears as the load on the engine decreases. It is NOT tiny like aa heat shield. Could this have something to do with the pistons in the engine, the motor mounts, or something else?

I have got a hyundai accent and I was getting a really annoying rattling sound from the boot i have been looking every where to find it and today i have sust it out if you open your boot up and just drive it round the block and it does not rattle then its probably the same problem that i had its the catch that the boot locks on to they must of been a bit of a gap to it and the metal was rattling together on the clip and the lock all u have to do to fix the problem is open your boot up then on clip on the car that the boot locks on to simple apply some installation tape around it so its pretty thick but not to much close your boot and problem solved it should be ok mine is fine now back to silence again now instead of a annoying rattle when driving.

I'm hearing a disconcerting sound coming from my car as of late. It's a rattling sound, almost as if someone were shaking a can of spray paint at the same frequency as the engine. It doesn't strike me as being a heat shield, it's a heavier rattling, not really a buzz.
The sound usually occurs when I am above 2000 RPM, however, it does not match an RPM range or the car's speed—it seems more closely associated with the position of the gas pedal—about halfway to 3/4. It does not make the sound unless the car is in gear and moving.
On cold starts, the engine fires and runs, but then takes up to 30-40 seconds to really get going at a normal RPM. Efforts to coax it with the gas pedal are delayed by a second or two before they kick in...
The car is a 2001 model, and has 44,000 miles.

I've recently been having a metallic creaking/rattle go on when idle or moving at slow speeds. I took it in during my 20k service and they said there was something with a cable and the heat shield... the service manager had also said something about the catlytic converter - but when I re-checked the service slip - nothing. This was originally in March.
The noise came back again recently so I had a different dealer check it out when I finally had the fuel tank recall done. They confirmed the noise and checked the heat shield (I had told them about the original complaint), but said there wasn't much that can be done - they made sure all the bolts were tight, but the noise was coming from the heat shield "flexing."
Most of the time it's fine and the noise went away for several months. It's subtle again, but if it becomes constant - it seems like I have a valid argument to have the heat shield replaced - seems defective.

I purchased a used 2010 Toyota Corolla LE with about 40k miles back in February of this year. Since then, the car has been issue-free and has responded accordingly.
Two weeks ago I noticed that the car when idle or at a stop light it'd make a subtle rattling noise (as if it was something behind the glove compartments rattling against metal). At 1st I thought maybe it was something inside, but as that week turned to days, I noticed that while I was outside the car and it was on and idle, I could hear the rattling from the right side of the car under the passenger seat (closer to the engine, as if right below where the glove compartment sat)--It is a constant rattle at the same frequency..meaning it doesn't rattle one way 1st and then another later. It sounds the same, but it is random.
It evolved from a subtle rattle inside to being a loud rattle outside under the car. I noticed that if it was rattling and I turned off the air, the rattling would stop, but after 20 seconds, the rattling would return just not as frequent.
It was advised to me that perhaps it was the blower...but the blower sits behind the glove compartment and should not sound so loud under the car. Not only that, but if the blower isn't on (when I turn off the air) it shouldn't sound...at least that's my logic for it.
The sound is getting louder and more frequent at this time and I'm just not sure what to do about this. I live in Miami, FL and hearing so many rip offs at mechanics, I don't know what this rattling is and I've already crawled under the car and see nothing wrong, nothing shaking violently, nothing.

My mother has a '04 Santa Fe 3.5. Her automobile makes a rattling/grinding sound when around 1000rpms/idle. However, the sound disappears when accelerating and drives like a charm. The sound returns once again around 1000rmps at idle or stop. I have changed the oil pan, replaced oil and filter and even put in a new battery. I'm not an aficionado when it comes to Hyundais (Subaru driver here).Car also has 180k miles.
