Elantra MD (2010-15) :: 2013 - Hum / Buzz At Speeds Over 40 Mph
Jun 22, 2016
In the last two weeks, our 2013 Elantra (we have a 2014 also) has developed what I can only describe as a "hum" from the front of the car... only at speeds over 40 mph. It sounds like a electrical transformer hum/buzz. Other than the sound, the car drives and performs as always. It just went over 52k miles.
If you are going 70 mph and put the transmission in neutral, it's still there. Not a transmission sound. If you turn the A/C on and off, it's still there. Not the A/C compressor. It does not get much louder or more pronounced as speed increases, which lead me to believe it is not the alternator or a pulley, and you can't hear it when the car is parked and you rev it up.
The only other source I can think of is the electric power steering motor. I am taking it to the dealer in a few days to let them see if they can diagnose and correct this issue.

Recently my car has been making a noise from the front and rear wheels (sounds like metal scraping against something). It is more pronounced on the driver side and there is a definitive roar at highway speeds. I have had the tires rotated, balanced and tire pressure checked numerous times and still no fix. It has 37K miles on it.

Just got rid of my 2011 Audi a4 for 2012 Elantra Limited with tech pkg. I like the car a lot but man is it noisy at highway speeds. Really makes phone calls and radio listening difficult.

My car has the clunk whenever I shift into gear (I have a manual) at low speeds and in low gears. Brought the car into the dealership and they think it's the front axles. Had one replaced (as they thought it was the passenger side axle) and clunk is still there. Went in to have the second one replaced, but part was not right. Waiting on the new part to arrive this week.
Axle? I honestly think it's tranny or gear related. Other than that, the car has been ok. I am going to work on sound deadening this week, getting my front strut bar installed and doing some research about the rear suspension.

I just got my new 2013 Persona Prius on Saturday. I haven't put too many miles on it (under 200) but I'm noticed that a feel a stuttering or hesitation when I reach highway speeds. Typically about 65 -70mph. I can't think of a better way to describe this but it feels like the when driving a manual transmission, when you need to shift to the high gear? That kind of stuttering feeling. I'm sure that it's not the same problem but it feels like that. Once I go faster, the feeling stops. Or slower. But going between 65 to 70, it's the same feeling.

So my 2012 Elantra developed a "creaking" noise coming from the wheel when warmed up and at low speeds. It almost sounded like really old heavy door when it opens that goes "thunk thunk thunk" as it sticks.
I usually work on my own cars, but for so me reason I took it to the dealership because I didn't know where it was coming from. After a 30 minute test drive to reproduce the issue, he took another 30 minutes to tell me that an "axle bolt" was loose and needed to be tightening.
I've never heard of an axle bolt - I'm only asking now because the issue's come back a few months later, and I know the dealership's gonna charge me again if I ask. Can't be that hard if it didn't take him more than 20 minutes to fix. Are they referring to the main cv/axle nut?

Today was the first day I drove my Elantra on the interstate with the sunroof open. When I was cruising at 65-70mph, I kept hearing a noise that I thought was coming from another car. It sort of sounded like a popping or thumping noise. After a few minutes, I reached my hand up and noticed the sound was coming from the metal bar that rises up a little at the front of the opening when the glass slides back. The wind was vibrating it and making it flap in the wind.

Took car in for normal service (69,000 miles) and had Tranny Fluid Service completed. When I took the car home I noticed some slight tranny slipping while accelerating up to highway speeds (so assuming 4th to 5th gear, maybe 5th to 6th). Took it back to the dealer and after a week it had a new transmission. Took it home and it slipped again, also only accelerating to highway speeds. Took it back and they told me they reset the computer that monitors my driving patterns. OK, not exactly sure what that means. So, now driving to work this morning it slipped (or maybe hesitated is a better word) again when accelerating from about 55 mph to 60 or so. Car has never had issues like this before, gas mileage is still in the 30 mpg range.

It could be the ECS kicking in or something but here's what I feel..... when hitting a rough patch of road at I'd say 25 miles an hour or greater and applying the brake over that rough patch of road for what ever reason, my foot is on brake pedal normal and it feels like the pedal gets ultra firm (opposite of pedal diving to floor if you lost brakes) or the feeling is like the brake pedal is pushing back against me, like the car is taking the brakes off on me for a brief second.....its a weird feeling and only happens on rough road when I'm at speed and have to hit brakes, all other braking times it doesn't do this
Good example is coming to a stop at a certain stop light that's got choppy asphalt right at the stop light line.....light turns yellow and I'm at speed and have to brake to stop for the light, it hit the rumbly road and feels like the pedal doesn't want me to brake and gets really firm, I stop and all, but then again makes me worry, because if I had to really stop fast and hard......would I ???
No alarm or alert lights come on, so I don't know ....
Car's got 8,000 miles on the clock ....

Noticed this the other day. While in drive, (didn't do it in park at first) activated the right hand signal. Noticeable buzz. Popped hood and sound appeared to be coming from engine fuse box. Took it to dealer and they have ordered a multi switch that apparently goes in the steering column so I guess the buzz in the fuse box is just a reaction to whatever is failing in the steering column.
On a side note. Took the 2012 elantra ltd in today because we noticed one of the original brake pads (front passenger outer) was a different dimension that the driver side. The pad material extended beyond the rotor braking surface and at ~40k the pad now has a noticeable knub extending on the inside part of the rotor in the groove between the shiny metal rotor and the studs.
Tech first said it was an aftermarket pad but we've never had service done to the brakes, only service at this dealer or at home. Later another tech apparently indicated this is a kia brake pad. How it got on the one side is a mystery! We have wheel locks. The car was bought new from this dealer but was a dealer trade so the only break in possession between the factory and us is the other dealer. Will be interested to see how Hyundai Canada or the district rep respond to this, but the dealer installed new pads (didn't turn the rotors) at their cost cuz they said they can't put it thru warranty.

Over the past few months I'd noticed an intermittent grinding noise coming from my left front wheel at low speeds. I took it in once but it refused to play along so I finally managed to catch it on camera and let the dealership listen to it. They booked me for today, saying it sounded like a wheel bearing (to which I agreed) and I dropped her off around ten, not expecting it to cooperate for the second time.
I got a call from the dealer around 2 PM saying that they were able to duplicate the noise and that when they took the left front wheel off and ran the car on the lift with the rest of the wheels off the ground, the noise went away. Even stranger still, when they put the wheel on the tire balancing machine and spun it, gronch, gronch...gronch, gronch....gronch, gronch. It was coming from inside the wheel! I gave them permission to dismount the tire from the wheel and about ten minutes later I got another call saying they'd found a handful of tiny hard rubber balls inside the mounted wheel/tire assembly that were rolling down the inside of the wheel and causing the grumbling at low speed.
Here's the kicker: they were in all four wheels! The tech even saved them for me so I could take a look and they don't look like anything mass-produced; some are larger than others, some are round and some are oval-shaped but when I dropped one on the glass advisor desk, it made a very clear 'Clink!'.

I am 1/2 way thru a 2 hour trip driving on interstate 75 in Florida doing about 75mph when all of the sudden I couldn't steer, had no dash lights with the exception of the radio plus the bluetooth still worked and braking was very difficult. I couldn't accelerate, nothing happened when I pushed the gas pedal. Neither turn signal worked but the emergency flashers did. Managed to get it on side of highway but then it got interesting; couldn't shift out of drive and couldn't turn the car off; I could turn the key but nothing happened. After sitting on the side of the road with my foot on the brake pedal for 30 minutes I tried turning the car off again and it magically worked. I sat there for about 10 minutes and thought I would turn the car on and see what happened; turned the key and it fired up like normal and everything was working just fine.

I have a 2013 Elantra w/tech pkg (bought brand new) and I have about 106k miles on it. Today I noticed this strange issue where when I let off the gas, it's like the engine doesn't notice right away and continues to apply power. It's only a delay for about a second or so, but it's noticeable enough that I'm writing this. It's really odd and I don't know what to make of it.

I have a 2013 Hyundai Elenatra 7 months old. the trunk opens by itself very often. I asked at the service department at the dealership and they say never heard of this problem. Also I came out yesterday the battery was dead even thought nothing was left on. I fell there must be some electrical or switching problem with this car.

I've had the car since the end of April. About 8 or 9 times I've had people come into my office and tell me that my truck is open.
If you own one of these you know that the word "hair trigger" does not come to mind with opening the truck remotely. You have to purposely work the trunk button. I really don't thinks it's because I sat on the key fob or bumped it so it accidentally opened the trunk.
As you can imagine I keep valuable things in my trunk so this is not good.

My 2013 Elantra won't shift out of park. I know that I should check fuses, but what fuses might be associated with this. (The brake lights are not affected)...

The guage on my '13 Auto is always 3-5 mpg optimistic vs my hand calculated mpgs. I find this unacceptable since the guage on my '08 350z's always within 0.2 mpg , and some times it is right on the dot! How inaccurate is yours? And I do fill at the same pump, though i know this isn't an absolute guarantee the tank is being filled exactly the same every time, but still, off by 5 mpg?

I have an Elantra 2013, the issue that I face is that when I turn OFF the A/C, the recirculation turns off by itself which I don't want as it will allow dust to accumulate through the open vents when the Car is parked overnight.
So each time I turn off the a/c, I need to press the recirculation button as well so I can turn off the car with recirculation ON. Doesn't happen in other cars..

Picked up my brand new elantra last week, however alarm was not working properly. It arms ok (i.e., horn chirps after two clicks, lights flash etc)...but when we tried to test the alarm (as part of my delivery inspection), nothing happened. We tried opening door without key, opening from a half open shutter etc.
Dealer promised to resolve issue, they've been good so far, but it's worrying me a bit, brand new car, I shouldn't have to think of these issues and take my car and leave it in the dealer garage for a few days for them to diagnose this.

I have a 2013 Elantra GLS. I use a USB stick to listen to music. Sometimes it would reset the center console/radio if I leave the USB stick in, but this time it didn't turn back on.
