I bought a used 2013 Hyundai Elantra with 29,802 miles on it on October 6, 2014. By February 2015 I started hearing a tapping noise from under the hood and a noise when I pressed the gas pedal which stopped when I took my foot off the gas pedal. I took it to a Hyundai dealership in February 2015 and it was determined I needed my engine replaced. Hyundai agreed to replace it under factory warranty. I had 32,500 I believe miles on it. The dealership had multiple cars sitting on their lot which needed their engines replaced. While I was waiting for a rental car business to come pick me up at the Hyundai dealership to get me a rental car to drive while my car was waiting to be fixed, I spoke to a couple who came in to drop off their rental car. Their 2012 Hyundai Elantra needed an engine replacement as well--at 23,000 miles. The dealership told me that these cars had engine problems more often in the northeast due to the more severe weather in the winter. I so regret ever buying my first ever Hyundai vehicle!

As others have mentioned, I have had both problems starting the vehicle (the car could not be started on two occasions so far, despite having adequate fuel and a charged battery), and with the rear of the car swinging out when traveling over a bump or on slippery road conditions (even at speeds as low as 35 mph, there is a noticeable kick from the rear of the vehicle, which has worsened with time). For both cases, the dealer was unable to find an issue, and/or said any kind problem was "within tolerance."

Car loosely steered barely off road, 1/8 mile from home, bumped tree 15' away, backed up, engine shut off (as usual since day 2 of lease), windshield heated to over 150 degree's in 35 degree weather, so I vacated car, which was in flames 2-3 minutes and burned to ash..had 5 months, daily problems, battery, fuses, ignition, numerous calls to dealer, shop, no help, could easily have died in firetrap alive, car dove itself, when & where it pleased, and was uncontrollable.even Hyundai motor finance has not paid on gap coverage in 11 months, ruining my credit to boot, and was over financed past legal limits, on a total new lemon and not only was car not replaced as promised, I cannot get a response from Hyundai, or Hyundai finance.,this was the biggest mistake of my life, and I will tell everyone to never purchase a Hyundai product. You should be ashamed.and lose your franchise license.I will have to sue to ever begin to be compensated for all you have done to me, and because of your product.

My wife was driving the car. It was a dark road in the night. Perhaps she didn't see the stop sign and crashed into a vehicle coming from right hand side, going in the same direction my wife was going. My wife crashed the other vehicle from behind. It was serious crash in which the entire front portion of the car is damaged. But the air bags did not come out. My wife had her head hit the steering wheel and had an injury. My complaint is "why did the air bag not inflate in such a serious crash?"..updated 10/06/14. Updated 05/13/2015

I purchased this vehicle in June 2013. I had no complaints until July of 2014, wherein my car picks and chooses when to start. I have looked online and there are many others who seem to have this complaint. I finally gave in on Aug. 24, after my car sat for two days because I could not get it to start. I called the Hyundai 24 hour roadside and had them tow it to the nearest dealership. The tow truck driver initially tried to start it, and it didn't. he popped the button nearest the top of the shifter and pressed it in, and put the car in neutral, it then started but sputtered like it wanted to turn off. He was able to drive the car onto the tow truck. The next morning, I spoke with the mechanic at the dealership who indicated that the car was starting for them just fine. He said there are so many sensors that it could be one, but they wouldn't know where to start as there are so many and could not make an educated guess. He wanted to keep it overnight to see if it would act up for them. It is now 2pm two days later and the mechanic claims there is still no issue, he said they have let it run all morning and it is fine. This has become ridiculous, especially when I see so many others with the same complaint, yet nothing being done. Help, NHTSA!

Unable to move the car out of park. The electrical worked (radio, windows). I insert the key and turn but the car wont turn over (start). I have to use the shift lock release to start the car. The problem occurs intermittently and there is no pattern.

On my way to work I was exiting the highway and I hit a bump. I was taken by surprise as what felt like the rear of the car bounced up abnormally and lurch toward the guard rail. The handling on rough surfaces is awful. This could lead to an accident. I just bought this car used and the engine is noisy which I am told this is the timing chain. I never had a car like this in my long life. The handling really worries me. Sucks!

Taking a corner at 5 mph in 2nd gear, heard a metallic sound from the engine. The engine cut out, lost power steering and brakes. Pulled over using the emergency brake to stop. Towed car to a Hyundai dealer. I was told the top of the piston had a crack in it that developed over time and finally failed. The failure caused catastrophic damage to the engine, which is being replaced under mfg. Warranty.

I'm having a tak, tak, tak sound coming from under the hood once I shut the car off. Also, you can see a spark while it is making the sound. I"ve taken the car back to the dealer several times for this and the scrubbing sound on the brakes and the missing while the car is idling. I'm told each time they can't hear or feel anything and to please come back if it happens again. I've been to the dealer so much I hate to go again.

While driving my vehicle at highway speed, the vehicle suddenly stalled without any apparent reason. I was in the middle lane of a three lane highway. I had to coast over to the side of the highway with no steering or brakes due to the engine failure. Once at the side of the highway, the vehicle re-started immediately and ran normally again for about a week when the same thing happened again, this time on a side street at approximately 15 mph. The vehicle once again started back up with no problem. It has run normally again as of this posting. Updated 10/23/2014

Vehicle owner smelled a burning type smell on a cold day when having the heater on full to warm the vehicle. There was no obvious smoke or fire. The second time the vehicle owner had the heater on full to warm the car, a fire resulted. The fire caused so much damage to the vehicle that the initial cause is unknown.

I rear ended a car and nearly totaled my car. For some odd reason the airbag never deployed during the time of impact.

Pulled over to shoulder on Florida turnpike to adjust seat belt and the car started a very rough idling and would not engage in drive. Reported it to dealer and Hyundai motor America and following was their reply: -dealer: This is a characteristic of these vehicles that they don't know how to correct -Hyundai: They are aware of the problem and are working to resolve it. In the meantime I am driving a car that is not reliable to me from a safety standpoint and two dealers in miami, doral and lehman Hyundai service managers have told me that there is nothing they can do until the factory tells them how to correct the issue, your assistance will be very much appreciated.

Vehicle was stopped at a traffic light and started idling roughly and engine shut off. Doral had a Hyundai motor "field engineer" ([xxx]) look at it on July 11 and I was informed through the service adviser that this was typical of these models and that she, personally, had chosen to ignore it; she works for a Hyundai dealership. Furthermore, nothing can be done. Please refer to previous complaint. Thank you. Information redacted pursuant to the Freedom Of Information Act (FOIA), 5 U.S.C. 552(B)(6).

My wife was trying to park her car when the car suddenly accelerated without her touching the gas or the brake. Luckily, she was able to stop by slamming on the brakes. I've heard recent cases of people not being able to stop when this happens.

When driving the vehicle on the high way I 29 N at about 68-72 mph the brand new vehicle engine stalled abruptly and the steering wheel froze and we were stuck in the direction the steering was previously turned it and it made impossible for us to steer it on to the shoulder and the vehicle behind us almost crashed into us. We were just a whisker away from getting killed. We had a near death experience and my fiance is still having nightmares about it.
