Lincoln - Towncar :: 2001 - Arbitrarily Surging / Making A Sort Of Grinding Sound

When I am driving, regardless of the speed at which I am traveling or the weather conditions, etc. The car arbitrarily surges, making a sort of grinding sound. I have to quickly tap the accelerator to stop it...a real problem if traveling in rush hour traffic, for example, so as not to run into the car in front of me. I have mentioned this to the folks who service my car but, naturally, it never does it in the shop.

Chevrolet - Equinox :: 2008 - Engine Made Sort Of A Buzzer Sound And Does Not Start

Recently I've been having some intermittent trouble starting my 2008 Chevy Equinox LS. The problem only occurs when I leave my daughter's daycare after dropping her off in the morning...so it's the second start of the day, after about a 5 minute drive. All other times the car starts fine. Here's a rundown of the symptoms:

-May 9th or 10th: I tried starting the car (at the daycare) and the engine made sort of a buzzer sound, and didn't start. Then, after a few seconds, I tried it again and it started right up.

-May 11th: I did some interstate driving (about a 1.5 hour trip each way). On the trip up, after about an hour or so, I received the following warnings: "Service Traction Control" and "Service Stabilitrack." After I turned off the car the warnings have never come back on (don't know if this is related to the starting problem, but figured I would mention it).

-May 18th: while sitting at a stoplight, the car was idling roughly - I had to really hold down the brake to prevent the car from lurching forward, and the RPMs were going between about 800 and 1500...haven't noticed any rough idling since, though.

-May 20-24 & 27-29: Again, when leaving the daycare in the morning, when I try to start the car, it sounds like a machine gun. It usually won't start the first time, but will the second time after still making that noise. Attached is a video of this. The odd thing, though, is that it hasn't done it the last two times I've left the daycare (I doubt the problem just fixed itself).

Subaru - Forester :: 2002 - Loud Knocking Sort Of Sound At Startup - Engine Shuts Off At Stop Sign

I have about 200k on my forester. Friday when I was leaving work I cranked it up and it made a loud knocking sort of sound. I drove it home (about 15 miles) and on the way the sound lessened. It was louder when the car was idling but she made it home ok. Next day, started the car and it happened again. Not more than 50 feet up the road we stopped at a stop sign and it sounded like a semi was starting up around the corner. Much to my dismay it was not a semi but my own car. Engine shut off. We pushed it back to the house and tried to check it out the next day. This time, we started it, didn't go anywhere, and within 30 seconds it turned off. Same loud knocking sort of sound. The confusing part is that all of this happened within two days. There was no gentle sound leading up to it for a few weeks or even a few days. Knocked on Friday, shut off on Saturday. What could be going on?

Prius (Gen 3) :: Metallic Plinking Sound When Braking?

I got my first Prius last week but something started happening I noticed a few days ago, that sometimes (between 30 - 40%) of the time when I brake there is a metallic plinking sound, and directly under where I let my non - driving foot chill out (which is basically the center of the drivers site floorboard), my foot can feel the plink as well

Prius (Gen 3) :: Metallic Clicking Sound - With The Windows Down

2012 Prius 3 with solar roof. Most of the time when I go over little divest in the road; just large enough to barely feel, I hear a metallic clicking sound from the front passenger side of the vehicle. It is only audible with the windows down. It only happens if I am going faster than around 10mph. Sometimes I hear a similar sound from the drivers side, but not as much as the passenger side. I do not usually hear it when hitting larger bumps that work the shocks a bit harder.

It really sounds like some loose bits of metal contacting each other. I do not see anything obvious with a quick visual inspection, but I have not raised the vehicle to really get a good look down there.

Lexus RX 2010-15 :: Metallic Vacuum Sound Seems To Come From Right Rear Of Car

I 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.

Prius (2004-09) :: Metallic Rattle Sound During Acceleration

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.

Sonata I45 (YF - 2011+) :: Metallic Rattle Sound At 2k RPMs

So on my new 2.0T Sonata I noticed a brief metallic rattle in the 2K-3K RPM range when you rev the throttle. I was very concerned.

The sales rep said it may be the heat shielding that is coming lose. He was concerned and said to bring it back when Service is open.

I just got back from the dealer: The service manager didn't know what it was but his tech said it was part of the turbo system, it's a 1/4 inch bar (parallel with the bumper) you can plainly see between the firewall and engine. He said what it did but I forgot to take notes.

I listened to another 2.0 Turbo Sonata on the lot and it has the exact same rattle when rev'd.

Elantra MD (2010-15) :: Metallic Clicking Sound Near Wheel Well

So 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?

Sonata I45 (LF 2015+) :: Grinding / Metallic Sound Under Acceleration?

I have been having a grinding/metallic sound when going up hills in 4th/5th gear. It sounds like if you threw metal into moving parts. I believe it's coming from my engine or transmission. When i was at the dealer last month for a campaign and ecm upgrade i mentioned this problem and they replaced the vcm motor assy, however the problem still exists. What could be causing this problem?

Phaeton :: Metallic Clicking Sound And Window Would Not Raise

So I decided to drive my car this morning after almost 2 weeks of it sitting in the garage, got to the parking structure, pushed the button to lower the windows so I can swipe my auto parking card and it rolled down fine. Then tried to close the window and heard this metallic clicking sound and the window wouldn't raise. Called the dealership and drove right to them to look into it. Now I am stuck with a Jetta until my car is fixed.

Camry :: 2007 SE V6 - Metallic Twirling Sound When Engine Idling

I 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.

Lexus IS 2014+ :: Metallic Squeaking Sound Only Happens At Certain Engine RPMs

Where this sound is coming from? I notice it more when the engine hasn't been turned on in a few hours or so. It only happens at certain engine rpms, usually a bit higher than idle. It's a bit squeaky, per se, may need to turn up audio on the video below to hear it. May need to bring her in (just did a 30k service too..)

Possibly a belt of some sort? My AC is on at startup.

Prius V :: Engine Ping (rattling Metallic Sound) Under Load

When 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.

Golf IV R32 :: Metallic Clicking Sound When Turn Hard Right Or Left

When I turn hard right & left, near the left wheel well there's a little metallic clicking sound. Either way I still don't what it is. Upon inspection when I removed the wheel the I noticed that the red portion with the large arrow is able to move clockwise and counter clockwise. Just curious as to whether or not this should be capable of happening.

Wheel baring, control arm and bushings have been mentioned from Le Shwab's workers... I dunno though I need Vortex's opinion

When collar 3 is turned all the way down it can't rotate, but I'm almost positive that collar 2 and 3 are suppose to remain in contact with one another to prevent movement of collar 1. Just making sure that my theories are correct.

Golf/GTI VI :: Loud Metallic Scraping Sound From Rear Brakes

I had a super loud metallic scraping and clanking noise when I was backing out of my driveway the other night. It was so loud I though my exhaust was dragging or something.

It turned out to be a rock trapped between the heat shield and rear brake disk. I pressed the heat shield away from the disk a bit and the rock fell out. It's kind of crazy that such a little rock caused such a loud sound.

Audi - A6 :: 1999 - Metallic Sound From The Front Driver Side

The issue is with my 1999 Audi A6 Quattro, I have driven 205,000 miles on the car and after 100K I started doing the maintenance. There is a sound coming from the front driver side, when you drive the car through a bumpy or gravel road, which sounds like “click, clank, click, clank”, to me its origin is from the suspension or the shock absorber. Both control arms were replaced due to misdiagnosis. Even the local maintenance shop can’t identify the issue, even after doing an alignment and inspection. I am not seeing any uneven ware out on the front tire.
