GMC - Yukon :: Pinging / Clanging Loudly From Undercarriage
Aug 1, 2011
My '05 Yukon begins pinging/clanging loudly from the undercarriage (possibly the muffler) after driving for about 10 minutes. After driving, the pinging continues for some length of time, depending on how long I was driving.
I live in the south and the problem began a couple of months after a winter trip to Chicago, complete with snow, ice and salt, and I failed to wash the undercarriage when arriving back home. There are some rust "freckles" on the frame and axle, but nothing on the muffler; the drive shaft is completely covered in rust. Could rust be the issue?

My knucklehead brother, re-living the past, borrowed my '96 Civic and sped off to a heavy metal concert - Mega-Death (may be prophetic here). His head was in a blissful dungeon. It was a 55 F day, near sundown, he'd gone 20 miles. He was going up a fairly steep hill and the engine started pinging loudly (something it's never done before), then he noticed the temp. gauge pegged. Instead of stopping immediately and looking under the hood where he would have found no water in the radiator, he "fixed" the problem on the fly by turning on the heater. The car continued to ping and run poorly. He continued to drive another mile up hill (about 2 minutes more) whence he stopped the car and shut off the engine, opened the hood, found ZERO water in the radiator (no steam). I have not tried to start the car since - had it towed. What should I do before trying to start it (besides adding coolant)? What should I do to find out if lasting engine damage was done? The engine ran like new prior to this - has 180k miles. Stevie1959 P.S: How much is he to blame for this - he's a 50 year old, experienced driver, amateur mechanic? - he tells me I gave him a car with no coolant in it (Not true!, I drove it that very day, no puddles of coolant anywhere).

Is this much water supposed to drip from the undercarriage if you've left the car running for maybe 10 minutes without moving it, while the AC is on?

When backing out today I noticed a pretty bad scrapping sound. It went away so I assumed that it was just a trashcan lid that I had run over. Tonight my mom came home and noticed a panel on the street. After looking at this thread [URL] .... I identified the piece that fell off.

As described, It presents when the rain is heavy and I splash the undercarriage with big amounts of water, then this very strong siren-like noise comes from rear and underneath the car. Once the car stops or undercarriage is no longer being showered by water from the splashing on the road, it quiets and stops. While present, if I stop the car the noise goes as well.
Some of my searches on google have come to other car forums and they are all seem to be happening on AWD cars, some blame the exhaust is affected by the cooling down effect of the water.

I have a 2002 camry 4 cyl. I bought at 65,000 miles. I drove it for 2 years and had a clanging sound that would come and go. My timing chain needed replaced because the sludge in the bottom of the pan clogged up the tube taking the oil to the chain. I religiously changed the oil every 3,000 miles, but I still get sludge. Is this an engine that was recalled by Toyota?

Undercarriage rattling when closing the driver door? Sounds metal and rattles for a split second. It caught me off guard the other day and here's a video of it.

Our 2009 Santa Fe has a knocking sound coming from the undercarriage of the vehicle. It cannot be heard when parked or when coasting. If I gently depress the gas pedal enough to rev the engine to 1500-2000 rpm when traveling at speeds of 35mph or greater it can be heard. The rate of the knocking / thumping appears to be related to vehicle speed, i.e., the faster we move, the higher the knocking rate.
Yesterday I emptied the vehicle of all contents and was still able to produce the sound upon demand.

I bought a 2011 golf 6 2.5 litre 5 door. The second day driving it I discovered a noise coming from under the middle vents in the dash. I took it back to the dealer and they said it was a noise coming because the cable shift was missing some clips and it was rattling in the undercarriage. They replaced the entire cable and I'm finding the same problem only not as loud as before (however it is still there). I'm finding it is making noise around 1200 rpm when going up or down a hill (especially when he car has back passengers in the back or any form of weight in the trunk). The moment I accelerate the noise goes away. Noise is also more pronounced when I have the summer rims and tires on (18s oem). At this point the sound is intermediate however it's something i want to get out of the way. What it could be.?

I have a 2010 Lexus RX 350 with 27K on the odometer. Since around the 15K mile mark I've been dealing with rear seat rattles, and that's a nice way of putting it. When I drive over the wonderfully pocked marked roads of Los Angeles, the rear seats vibrate, rattle and clang as if they are coming apart. I replicated the noise for the service guys at my local dealer. To their credit they replaced the track locating pins on the rear seats.
Unfortunately, that made things worse. The car rattles and clangs more than before. It has gotten so bad that I am considering selling a car which I bought outright just 2 years ago. By the way, I have already ruled out common sources of rattle complaints like the trunk cover.

I have been hearing a rattling or maybe more a banging clanging sound coming from the right rear of my 2007 3 door accent. It almost sounds like something is loose, but I have never identified anything. The tire tools are secure and there are no loose panels either.
It almost sounds like the strut is banging around. My wife did bend the rim on the right rear a couple of years ago. I thought maybe the sway bar was broke, until I realized this car doesn't have one.

I had my E in for service today to get her fluids changed and to replace her engine oil with Synthetic finally (second service for her).
I had noticed a rattle in the undercarriage for a few weeks now and assumed it was a common TSB for a heat shield that rattles. As it turns out, it is the resonator pipe that needs to be replaced (under warranty). I've never had to replace one before so hopefully it's just a one-off!
Otherwise, I can already tell she's happy to be filled with some wonderful Synthetic...

My 09 FX4 Screw has developed a strange thumping sound coming from the undercarriage within the last month or so. Very noticeable when turning on even terrain. It's just barely under warranty and I am planning on taking it to the dealer.

So I cold started our V today and the electric motor turned on. When it switched over to the gas motor when I turned the heat on in the car, there was a violent plastic on plastic clunking or clanging type of noise. Sounded like something sheered itself off the motor. Then after about 5 seconds, it went away. Drove the car for a while, no check engine lights, no other weird noises, no problems. Engine seems like it has been ticking a bit in all this cold weather but I figure it was just lifter noise so I ignored it. Car is a 2012 with approximately 17k miles on it. Going to try to see if the same thing happens when I cold start it tomorrow morning in the frigid air. Car just had its 15k service and the dealer said it was perfect.....I don't get it. This noise was freaking loud. We LOVE this car btw...never thought I would say this about a hybrid because I am a HP nut, but this is the best, most functional car we have ever owned so far.

Why has my vehicle started making this loud clanging noise when shifting gears? (Automatic) It sounds like someone is hitting a wrench against the metal, most notably between Reverse and Drive. Also, the body of the vehicle is noticeably lower on one side with no flat tires.

I was climbing up a hill on the highway, and I was aware of my issue by the time I hit the top of the hill - my car far into the red zone on the temp gauge.
I pulled over just after i got off, let it cool for a few minutes, check oil and coolant and they seemed fine (from what i could, but it was dark. Drove home because it was only a few mins away, and it had cooled a bit already, but it started sounding really weird at low rpms (1200-1500) almost a clanging noise.
Just as i was pulling into my driveway, there were a whole bunch of weird noises, and at least one of them was me losing coolant from the cap. Turned off the car and the coolant overflow box was completely full, and the radiator cap had leaked some too.
Some other things i noticed - sounded like boiling water inside the large hoses, hoses felt empty, and the coolant box emptied all of a sudden after the hoses sucks everything back up.

I got in, stepped on the brake pedal and press the power button. Then the Prius ICE started, it started clanging and violently shaking the entire car. The clanging was sounded like metal on metal or something, it was loud and it was like the engine was seizing up. I stepped outside and the whole front end was buckling up and down. From my perspective, it seemed like the car wanted to lurch forward if I didn't have the parking brake engaged. I had Park engaged and also the parking brake on. I thought it would go away but it persisted. I turned off the car and immediately restarted. When the ICE started the 2nd time it felt a bit rough but finally the clanging noise went away. I didn't have time to look on my scanguage for any codes during the event. Did this cause any permanent damage?

I have a 2015 Sonata Sport 2.0T with less than 7k miles on it. I commute about 14 miles to work. During this drive, I hear a clunk/thud in the undercarriage that occurs usually 2 or 3 times each drive. It sounds like it might be coming from the wheel well. Originally I thought my tires were picking up rocks on the road and throwing them up into the wheel well. If any of you are familiar with the sound of dried mud releasing from a tire or the wheel well while driving a truck, this sound is very similar. It might just be me, but I feel like it is occurring while turning the wheel/straightening it out after a turn. Today it happened while changing lanes twice, and once taking a right hand turn semi-quickly at a green light. I know that I am not running anything over that is visible while driving.

So I had been noticing a bit of wheel hop in third gear before my UM flash. Just got the flash a few days ago, and I love it. But since then two things have arisen:
- When sitting at idle, the car vibrates. I can feel it through the brake/gas pedals and steering wheel. I didn't notice it prior to the UM tune. It's like an undulating feeling even more than a vibration.
- When upshifting, I now seem to get a clanging sound/feeling if I upshift anywhere less than about 3200 RPMs. It doesn't always happen, and it won't happen if I'm really fast with engaging the clutch after taking my foot off the gas. But it is disconcerting.
Prior to the tune, I had gotten used to the sort of bucking and whatnot when you let off the gas and learned how to shift to minimize it. But now it isn't as easy to do a mellow, smooth upshift under 3000 RPM's...i.e. if I just want to pull away slowly from a stop. My question is, do these sound like symptoms of bad motor mounts? The car has just under 25k miles on it. The mounts are all stock. I was wondering if the UM tune was just enough extra power to put one or more of them over the edge.

I have about 2000 miles on a new V-8 and there seems to be a loud tingy noise if I really get on it say above 4500 revs either driving or in park. It seems to be coming from either the catalytic converter or exhaust area. It is a very metallic clanging noise that is very audible outside the vehicle under heavier throttle positions, almost like a metal plate hitting another piece of metal.
