When i drive my car or have it parked for a short amount of time, a loud popping noise comes from the car, can't tell where from. It is so sporadic and happens at such odd times that to take it into the dealership might be futile, unless they have heard of this before. It is loud enough that I can hear it inside the car and it sounds like it is coming from the passenger side of the car. Sometimes it is running while parked and makes the noise or if the car is turned off, I will go about 20 feet and sit and it will make the noise. Usually it is right after it has been driven, not sat for a long time. It made me wonder if taking heavy objects in and out of the trunk could be causing the noise. When I put a heavy object in the car is it causing the flooring to bend, then when I take out the heavy objects the flooring is coming back into place? This seems almost unlikely because I have been putting the same heavy items in and out of the trunk since I had the car. Also, it seems that the noise started after I got new tires. I don't remember it happening before then. I had to get all season tires to replace original ones to drive in the snow.

First off, what car do you have? Also, if you could get a video of the noise that would help a great deal. a popping noise could literally be coming from anywhere and caused by anything. actually hearing the noise will help narrow it down and if all els fails, it will let the dealer know what to listen for.

Given your description, it is HIGHLY likely that this is just the exhaust manifold, exhaust pipes or the catalytic converter cooling off and "popping" due to the metal expanding and contracting.

On some cars, it gradually goes away as the car ages but on some it continues to do it seemingly forever.

This is correct. A lot of my cars have done this from big luxurious cars to small 4 cylinder commuter cars, it's typical.

I am have the same issue with my 2013 Elantra. Dealer replaced the muffler last fall & is now saying that they need to replace the muffler again,
Mechanic said the popping sounds like a dent in a gas can popping back out
I'm sure this must be happening to others.

I am having the same issue. dealer replaced the muffler last fall & now says it needs replaced again. Mechanic test drove car to heat up, put on hoist & after about 5 minutes the muffler popped. They described it as the sound of a dent popping back out of a gas can.

there has to be more people this issue, looking for answers

I hear the same thing! Can't seem to nail the source but if I had to guess its passenger side rear. Sounds like a tin can popping back into shape.

Let me know when you find an answer to this one. I have a 2015 with 36,000 miles on it .. Drives me crazy too.. Of course when you take it in they say you have until the 60,000 point. We can't get it to replicate... Yada yada right, so what to do when it becomes broke down on the road for a dealership..oh don't worry about it? :-(

I get that it can be frustrating bobbi, but if YOU who drive the car everyday cannot readily duplicate the concern how is a tech suppose to during a brief (by comparison to the time you spend in the vehicle) test drive without getting lucky. The techs DO try their very best to help people and what is what we are there for. I've spend hours driving cars over the course of days trying to duplicate customer concerns with no luck, only to be called lazy or not caring. Your best bet is to leave it at the dealership for a time for extended testing. and if it DOES end up broken down cause you insist on coming in and waiting for a nonanswer then taking the car after and hour then there is a number both in your owners manual AND on the drivers window for Hyundai roadside assistance that will tow you to the nearest dealership.

2012 Elantra Rear Popping Sound

I hear the same thing! Can't seem to nail the source but if I had to guess its passenger side rear. Sounds like a tin can popping back into shape.
Has anyone found an answer to this issue yet? I quoted the above because this best describes what and where I am having the issue with our Elantra. This sound can range from fairly faint to really loud! If it was always very faint I suppose it wouldn't cause me much concern. This being my very first brand new car purchased, I guess I expected less drama. The sound really annoys me and concerns me. I am going to make a 3rd service appointment to have it checked. Unless this is figured out, I can't say I will be replacing this Elantra with a new one!

Please share any useful info on this topic. Losing my patience over this **** noise!

Thanks

My 2013 Elantra is making that popping noise to after driving and putting the car in park. Just got home from my local Hyundia dealer and they said it needs a new muffler. Luckily the car still under warranty. They had to order one.

I have been hearing that popping noise also coming from the rear end of the car. Took it to the dealership today, they test drove the car and pulled it into the garage and heard the noise. They said it needs a new muffler, so their ordering one. Thank God it's under warranty.

2013 Elantra Coupe

What is it about this car that is making my ears ring and my head ache after driving it on the highway? It is beautiful. Sounds solid, until...
Is this a common issue? Is this an issue that can be solved? Who should I turn to for help?

Thank you for any direction.
