Have a metallic/rattling sound under my car while idling. Don't hear it while driving. 2010 Mitsubishi Outlander
Here is link to sound file [URL] ....
I have a 2001 Saturn SL2 1.9 liter DOHC. I am getting a metallic rattling sound from under the car. The sound happens only at certain RPM idling speeds; what could this be?
View 11 RepliesOn three separate occasions, while driving, my check brake warning light has come on. When I brake, it immediately turns back off. On the second occasion it came back on about a minute later, but again, turned right back off after pressing the brake. There is no rhyme or reason to when this happens--the first time I was going about 25mph, the next two times it happened on the highway when I was going 55. It has happened within a couple of minutes of starting up, or after about 15 minutes. I haven't driven it for further than about 20 miles since it started, so I can't speak to whether it continues to occur on long drives or not. Sometimes it doesn't happen at all.
I haven't experienced any difference in braking--same amount of pressure when I press the pedal, same stopping distances, no vibrations or noises, etc. It was also recently at the shop for an oil change and tire rotation. The car is about 2.5-3 years old and has 20,600 miles on it (I don't drive much!). I checked the brake fluid; it is smack dab in the middle of the min and max lines, and it is clean. It was also just in over Christmas for the big 2 year/30,000 mile check and everything was totally fine.
Past 6 months I have a vibration/shimmy in '08 Outlander when accelerating in first gear (automatic). I can feel in my foot on accelerator and when passenger seat is empty the seat belt vibrates against door panel. It is not in steering wheel or tires. No hesitation or skipping in engine, just vibration that goes away once car gets into 2-3 gear. Dealer said transmission tested fine. Naturally.
View 1 RepliesOne thing you hate to hear when you go to a mechanic's is "that's a common problem" and "there's no permanent fix for it." Since we moved to a shady street, my car is leaking dirty water on the inside passenger side from under the dash, especially when I make a left turn. It really can start to smell bad and I now keep a bucket under the dash and have to leave the window cracked despite the daily rain in Tampa. Twice I have had the lines blown out, but I was told the problem would come back and to really clean it out and that the problem would come back anyway after that. According to my mechanic, the problem stems from the leaves getting inside the engine and clogging up some line. And to everyone else, don't buy a Mitsubishi Outlander.

I have a 2003 Mitsubishi Outlander. About two months ago, I replaced (myself) the radiator fan because it had stopped working. I bought the new fan on the internet and it was fairly easy to install. It was a little louder than the original fan, but it worked great. Last week it suddenly became louder and stays on for a minute after I turn the car off. Is the fan defective? Should I return it? Should I ask my mechanic to test it? Or just ignore it?
View 6 RepliesI am the original owner of a 2007 Camry SE V6 with 95K miles.The car has been meticulously maintained. About 2 weeks ago I started to notice a mysterious sound coming from the passenger side of the engine ONLY when the engine is idling. It has a higher, light pitch but when revving the engine slightly it goes away. Obviously when driving it can not be heard with all the other road noise etc. Also it makes this sound at different times, sometimes days with no noise, very irregularly. I checked that section of the engine bay and see no moisture, leakage or discoloration anywhere. Also serpentine belt shows no wear or wobble. Could it come from the water pump? I am very concerned that something will soon snap off, break and leave me stranded.
View 6 RepliesWhen 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 RepliesMy 2002 Dodge Grand Caravan has a sound metallic rattling at about transaxle area (I am not sure if it's a transaxle issue) when it's cold but when it's at operating temperature, I don't hear it anymore. Fluid level is correct and clean, I just have the fluid changed. Shifting is fine, just annoying sound, not loud but it can be heard easily.
View 4 RepliesFront end makes metallic rattling/clanking sound. This happens when I make a right-hand turn, and the noise comes from the left-front wheel area. I describe it as the sound of dropping a handful of pots and pans.
View 4 RepliesProblem description: A loud metallic rattling sound from under the car under moderate to heavy engine load, only when engine/exhaust is/are cold. It is noticeable from within the cabin with the windows rolled up and the sunroof closed. Crack a window or the sunroof and it's pretty loud. The first time I heard I, I thought "this is not good".
This is not an octane ping or valve train noise. It sounds like a coffee can with marbles being shaken in concert which what might be the rapping of a V8 engine's exhaust. I had a Sunbeam Tiger that rapped in the upper rpm ranges and this reminded me of that but instead of rapping, it shakes a can with marbles.
There has been much discussion and speculation as to what causes this. It does seem to occur only with late - 04 and up V8 Touaregs with the "sport" exhaust that replaced the "std"(?) exhaust used on the majority of the 04s.
Observation: I looked very closely at the heat shields, looking for ways they could rattle. On the passenger side (LHD), the heat shield has three main sections:
- Front: around/near the secondary cat (tightly secured)
- Rear: around/near the rear differential (tightly secured)
- Middle: between the two mentioned above (loosely secured)
The three sections overlap a little where they meet. It was very easy to tap on the middle shield and make a loud metallic sound. I put my finger between the two shields (where they meet) to isolate the two metal pieces and tapped again, and the noise was gone.
Theory: The harmonic resonance of the exhaust under load vibrates the middle heat shield and it rattles against the front and/or rear shields. As the shields heat up, they flex enough to provide clearance between each other and the noise goes away. This may be unique to the "sport" exhaust if (and I am only speculating) the heat shields were changed (in design or fitment) when they changed the exhaust.
Experiment: I tried a very simple experiment. I slightly bent the edges of the middle shield (~1/2 inch) where it was coming in contact with the front and rear shields. The allowed me to tap rather hard on any of the shields without them rattling against each other.
Result: I make the tweaks to the shields Sunday night. When I drove to work this morning, I put the transmission in sport mode and ran WOT until it shifted. Normally, I would have heard the sound (very loudly) but it was gone. No metallic sound. Not completely convinced, I repeated the experiment on the way home and, again, the sound was gone.
Summary: It was cool out when I was going to, and from, work (64F) and this would normally be the perfect set up for making the sound. I think that tweaking the heat shield has solved the noise on my Touareg. I am tempted to go back under there and pop-rivet a little brace between the shields so that they cannot rattle against each other again. On the other hand, I may just leave it be and do the pop-rivets if the noise comes back.
Anyway, I was excited to find a potential solution for my Touareg and wanted to share it will you all. I will post back after a while and report how it goes in the long term. Lastly, I really liked being able to put the air suspension in xtra-offroad and get under the car (easily) without using a jack....
Tis the first of "Squeaks and Creeks" from me. Not really the best thing to hear, sitting at ~24K miles. Anyways, until (if) i can get a sound clip, I have this metallic rattle that only occurs about 1-3 mins after i start the car. This just started happening yesterday, and nothing out of the ordinary happened.
I start the engine, hear a raspy rattle from what sounds like under the engine, and if i give it some throttle it increases some, but not to the point where it sounds like something is banging around. It goes away after a few minutes so it could be anything. Shifts are still smooth, driving and getting on the gas does not fix nor make it worse, either in neutral or actually rolling. It simply goes away with 3 minutes time or so. It seems to have a limit for how much 'rattle' it gives off, and its something I can accept.
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....
View 4 RepliesRecently 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 RepliesAt idle, what sounds like my transmission is making a scratchy/rattling sound that I haven't noticed before. What it is? (Be careful it's loud.)
View 6 RepliesI have a 2015 IS350 F-Sport. While accelerating, the engine sounds fine, but it sounds aweful when idling. Don't know how else to describe it other than like a rattling sound...it's just not smooth. Is this "normal" or should i schedule a service appt for my car?
View 5 RepliesI have an issue with my 2011 350 that is quite perplexing. I get an intermittent sound... best I can describe it is like a metallic vacuum sound that seems to come from the right rear of the car. There is no pattern to when it arises... comes and goes. I've been to the dealership with it 3 times and of course it did not occur. They must think I am hallucinating. I thought it might be an exhaust problem.
View 6 RepliesSo fairly recently, I've noticed a metallic-ish click like noise from my back rear driver side wheel. I hear it on occasion when sitting down in my car and the car tilts slightly. I can reproduce the sound when I take my hand and rock the car just a little bit. What that might be? Or if I should be concerned?
View 9 RepliesOn the December day my 2013 Prius Five model (hatchback with all the safety add ons, bigger wheels) turned 18 months old, i was on the way to have one of the freebie services. I heard a metallic rattle, seemingly coming from the back of the interior. It continues and I cannot find a source for it. I just read a thread about rattles in the 2011s. Not particularly comforting given what I spent on the car.
Is this something I could have the dealer chase under the warranty? (this is the first new car i ever bought in my 50 years of driving, so my familiarity with new car warranties is a little thin.)
My dealer has been pretty responsive -- swapping out an interior door panel as a freebie when the armrest portion separated from the lower portion and collapsed into the door.
Was about three blocks from home when the front of the car started making a horrific metallic scraping sound as the front wheel turned. I mean LOUD. Did a quick look for something stuck in the wheels somewhere but nothing. It's not like a branch stuck in the wheel sound, but scraping a shovel on a steel beam kind of sound. Braking seems to change the makeup of the sound, but did not stop it. Parked it in the garage.
I pulled the left wheel off, looked and looked, and looked. Nothing. Fear and sadness setting in. Everything looked normal....except....a faint line on the rotor very near the inside edge. Got a mirror and looked some more, and there, wedged on the inside edge of the pad's metal part and the rotor, was a rock the size of a bb. At most. Got a small screwdriver and hammer and popped it out. Done. Sheesh.
Seriously it was so loud it was amazing. So store in file folder for future reference if needed.
The line can be felt barely with a fingernail and is half the width of a pencil lead, and goes under the innermost 1/8" of the pad. I'm thinking do I want the dealer to pull and turn it, or is it going to affect my braking at all. Pretty much gonna leave it be I think.
