Prius (2010-12) :: Loud Clattering Noise From Under The Hood Occurred Upon Startup

Twice during the 6 months that we have owned our 2010 Prius, a loud clattering noise from under the hood occurred upon startup. After shutting it down and restarting, all was normal. It sounded like an engine that was getting ready to throw a connecting rod. The dealer could find nothing wrong and when I contacted Toyota's hot line, they were clueless as well. One service writer suggested the ABS as the source, but I've owned 5 other cars with ABS and never heard anything like it.

Elantra MD (2010-15) :: Popping Noise Coming From Exhaust When Downshift

Okay so with my old Accent I had the same Magnaflow exhaust I have now on the Elantra. Sounds identical with one exception; When I'd down shift with my Accent I'd get some popping coming from the exhaust. I get no such sound with my current set-up. Now I know some people don't like it but I do.

So my question is simple... Would removing the resonator (assuming the Elantra's have one) or doing something else to the exhaust give me back my wonderful popping sound?

Prius (2010-12) :: Clattering Noise Coming From Suspension

Since new my Prius V has had a metallic clattering sound that comes from underneath the car. This can be replicated when driving over lane divider dots on a quiet street with the windows down. To investigate, I put the car on ramps and looked around; I was almost certain the sound was coming from a thin aluminum heat shield that is just behind the engine. Tapping this shield made a similar sound to what I heard coming from under the car while driving over bumps and such. The shield is poorly attached with those "fun" push pin fasteners that seem to be liberally deployed all over the undercarriage. I decided to re-attach the shield with a judicious circular application of silicone under each of the holes in the shield and let it dry. The clattering sound I heard previously when tapping the shield was gone. Out for a test drive and still there!

I just had the first service done, and of course the tech couldn't hear it on his test drive. Unfortunately I was pressed for time, so I wasn't able to take a test drive with the tech. I will drive the tech around next time and demonstrate it.

Elantra MD (2010-15) :: Semi Loud Tapping Noise Coming From The Engine

I have noticed that when the car was in park today right after I started her I heard a semi loud tapping noise coming from the engine... It slowed down when I turned the wheels or played with the brakes... As I went into drive the noise went away after about 20 feet of driving..

What this could be? Is it normal... Just bought the car last week with 45K miles on it and just want to make sure if it is a normal noise or not or whether I should bring her into the dealer.

Elantra MD (2010-15) :: Loud Squeak Coming From The Wheels In The Front

I have been hearing a loud squeek coming from the wheels in the front. It sounds like a brake wear bar but isn't it a little early to replace the pads already? I searched the forum last night briefly and found some threads where people commented the brakes should last much much longer than 50000.

I do not ride my brakes and I don't think I am hard on them. They still work great and do not feel worn. The noise is constant (not only when i turn the wheel) and it goes away after a certain speed.

Prius (2010-12) :: Engine Kicks In And There Is A Loud Exhaust Noise

When the battery power is low, the engine will kick in and then there is a loud "exhaust" sound. Are those really sound from the exhaust or some other fan?

Prius (2001-03) :: Loud Noise Coming From Exhaust System / Catalytic Converter Replacement

After hearing some loud noise coming from my exhaust system, it was determined that there is a hole (from rust) in part of the cat. assembly. Three shops advised for replacement, there are no aftermarket products for this unit. I have NOT gotten any error codes, the only problem is the noise. What to do? The car is 10 years old with 86000 miles. I have been reading about some of you getting just the one piece and having it welded on, but I do not believe any of the shops here will do that, and indicated that it would be a very temporary fix.

Elantra MD (2010-15) :: Ticking Noise From The Exhaust

Since I brought my car to the Mississauga Hyundai dealership for an oil change and check up for a rattling sound my car has come back to this new ticking noise from the exhaust.

I had the dealership do an oil change (my own synthetic bought Quakerstate oil) and apparently they put a clamp/bracket because my exhaust was making the rattling sound. The rattling sound is gone, BUT i have this ticking sound every time after the car is shutoff no matter short or long drive. Also can hear it while driving sometimes.

I have took the car back to the dealership and they told me this is normal, the thing is my car has never made this sound before i took it to the dealership. The hyundai dealership claims that this is just exhaust cooling down/ heat expansion. I am curious to why it never made this sound before.

It is a 2011 Elantra gl with 67,000km here is a video after a 15 min drive : [URL] .....

Elantra MD (2010-15) :: Ticking Noise From Exhaust While Driving

Compared to my last car, the ticking noise you normally hear from the exhaust after you shut the car is louder in my elantra. But that doesnt bother me. However, i can hear that same exhaust noise while im driving. Its coming from underneath the middle of the car not the engine. My old car did not make that noise while driving, just after i shut the car off.

Nissan - Frontier :: 2008 - Clattering Noise Started Coming Out Of Dash

I drive a 2008 Nissan Frontier, bought new in Nov. 2007 with 53,000 miles on it. A few months ago, at about 50,000 miles, an annoying clattering noise started coming out of the dash. The noise was coming from the vent area of the passenger side dash and occurs when I start the vehicle or adjust the AC from Max to norm. I went online and found that the noise occurs in many of the full size Nissan SUVs, and is a failing Vent Actuator part. Doing further research, I learned, the part is fairly cheap, but buried in the dash and difficult to get to.

Of course that means that labor is very expensive to replace this part. Nobody seems to want to take the time to replace the part, except the dealer who wants $500 labor to do it. I have found dash diagrams and since it is cooling off lam thinking about taking on the project myself. With the vehicle having such low mileage, and little stress being put on the part, I feel that the part is of low quality and replacement should be covered on some kind of warranty. Nissan probably feels it is not a safety issue, but the noise is very annoying, and certainly lowers the value of my vehicle, that has otherwise been pampered and in like new condition.

Elantra MD (2010-15) :: Loud Clicking Noise From Column

I hadn't driven my car for nearly a month and when I returned I noticed a rather loud "clunking" noise when moving the A/T out of park. The sound is coming from the steering column and is quite pronounced. Is it normal?

I am also hearing a sound something like a bad wheel-bearing while accelerating that I never heard before. It sounds like it's coming from the front end of the car.

Elantra MD (2010-15) :: Loud Noise On Startup When Car Is Cold

When I start my car I hear this very loud noise. I think it is coming from the exhaust but not sure. This only happens when the car is cold(not weather) and after a few minutes the noise is gone. I have aftermarket lowering springs on the car, do you think that caused the problem?(I'm thinking no)...

Elantra MD (2010-15) :: Loud Flapping Noise Right After Starting

I just purchased my new Elantra 2 weeks ago. A few days later, just after I started it first thing in the morning, it began making a loud flapping noise (seemed to be coming from under the hood). It's been doing it every morning since. The dealership said they couldn't hear anything unusual (after keeping it overnight, then starting it up first thing the next morning).

Elantra MD (2010-15) :: Loud Engine Knocking Noise

My car has 63 000 km and engine is making loud knocking noise all the time. Dealer took a quick look and he asked head office. Now he wants to run some tests to see which valve is bad. He's hesitating between repairing or replacing the engine. I'm really disappointed of Hyundai quality. I really hope that I get new engine instead of poor repair job.

Elantra MD (2010-15) :: 2013 GL Loud Noise Over Bumps

Picked up my brand new 2013 Elantra 2 nights ago. 51 Km's on it when I drove it off the lot. Immediately noticed it was making a very loud noise whenever I hit any road bumps, potholes, sewers, train tracks, etc.

I can't tell if it is coming from the front, or back of the car. Many of the threads on here seem to be talking about a common rear shocks issue? Also read a lot about faulty struts? Swaybar?

Elantra XD (2001-06) :: Loud Grinding Noise Coming From Front Of Car When Decelerating At Low Speeds

Having problem with my car (2001 Elantra GT) - over the last month or so it's been occasionally making a very loud (not but consistent) grinding noise coming from the front of the car when decelerating at low speeds. The noise sounds like gears slipping over each other but cuts in and out. It's pretty loud and not a nice noise to hear! Sometimes it makes the noise when I brake firmy but not until I reach lower speeds... mostly it's just when coming to a stop, but it did it once last week when I was pulling very slowly out of a parking spot and not even braking.

As it's become more frequent (going form maybe once a week to several times every car journey) I have started to feel something in the brake pedal also, like there's something kicking it from behind. I took it to a mechanic and had to pay a ton of money to get a broken front left ABS ring replaced (it also had the front right ring replaced in May), and within 2 minutes of driving away from the place the noise was back. Before I spend even more money that I don't have on taking it back for extra diagnosis.

I'm told that this is almost certainly the ABS system that has a fault even though the ABS light never shows except when I start the car, and I've taken the fuses out of the ABS in order to confirm that it is. I haven't heard the noise after a few days of driving with ABS unplugged so I think we can be reasonably sure here. Is there anything that I can check myself or test (I'm not very handy when it comes to cars) or can you tell from this information what it's likely to be? Other things that I've noticed with the car which may or may not be relevant are:

- the warning lights for brakes, ABS and TCS are all lit with the fuses for ABS1 and ABS2 taken out. I take it this is normal for all 3 to illuminate with the fuses out?

- since unplugging the ABS I've noticed a slight metallic squeal from the brakes as if the brakes are worn down. Didn't notice this before I unplugged ABS though it may have been there, not sure.

- sometimes when going over a speed bump or just a minor imperfection in the road I hear a clunk in the front of the car and feel something move in the underside of the car. Happens mostly at lower speeds also, but not if I go over the bump really slowly.

- in the fuse box when I took out the ABS fuses I noticed there was a bit of minor melting/brown burn marks on the top of the connections marked (iirc) ECO3 and ECO4 on the diagram (large white connectors). Is this anything to be concerned about?

- sometimes when I have air coming into the car through the air vents it will become significantly warmer for a few minutes, then slowly go back to normal. Can't think of any circumstance that links the times when this happens (eg. speed, weather etc).

- the oil pan has a leak which is on the list of things to fix when the car works properly.

Elantra MD (2010-15) :: Loud Ticking Noise From Engine When Temp Below 25F (-4C) For 5 Minutes

You know the ticking noise that is normal for our engines? Well, below 25 degrees F, it is the most worst noise ever. It sounds like the valve train is going to explode. Just keep in mind I've driven many cars. The ticking noise shouldn't be outrageously loud.

But my main problem that is worrying me is this WHOMP-WHOMP-WHOMP noise. The higher the RPM the faster the noise. Doesn't matter if the car is moving or not and I know it's coming from the engine. I hope it's not related to the loud ticking. It only happens for approximately 5 minutes. After that, there's no WHOMP sound and the ticking goes back to normal sound levels.
