I turned the key to the start position so I could start the car, but it would not start up. The car was in park. I did some research on the internet, and found some videos on youtube, and people commented they were having the same issue. Some people mentioned that if you turn the key so you can move the shifter from park to neutral, and back to park, the car may start up. I tried exactly this, and as soon as I attempted to move the shifter to neutral, the car started up. It appears to be a problem with the inhibitor switch, which I will try to get that replaced by the dealership if possible. Since many people are experiencing this same problem, there should be a recall for this issue!

Today I went out to start my car after it sitting out over night (living in North Dakota my vehicle has always sat out in the cold over winter and started with no issues) and it would not start. The lights, doors, widows, everything else electrical worked just find, but the engine will not turn on. I tried charging the battery and jumping it with a friends vehicle. Nothing has worked. I have been reading online this is becoming a common issue among Hyundai's. I would hope Hyundai will soon have some answers and fixes for this issue.

2012 Hyundai Elantra would not start when in park, even though the battery has a full charge. Shifted to neutral and back to park, and it started on the first try.

Car would not start. After multiple attempts at turning key, it finally started. Lights and horn functioned properly, but I replaced the battery anyway. Car would still not start on first few attempts. Engine would not turn over at all, then after several attempts at turning key, it would start, as if nothing was wrong. Brought it to dealer, they said they cleaned out some parts of the engine and updated the computer. The next day I had the same problem again. Brought it to the dealer, and they said they changed some fuses. Less than a week later, still the same problem. There are multiple incidents of this happening for other owners of this car which I found online when I was looking to diagnose the problem.

My car was parked outside overnight and I used the key fob to unlock my car. I then tried to start the car but it would not start. I had my foot pressing on the brake and pushed the ignition button and the lights/radio would come on but the car made a click noise and would not crank over to start. I tried this 5 times before it started. It was not that cold so weather was not a factor. I then drove to work and at lunch the same thing happened. It took 5 tries before the car cranked over to start. The brake pedal seems to be locked and then finally it has some give to start the car. I had taken my car to the dealership 6 weeks prior for this same issue but they said they could not find a problem as it started for them every time. It is starting to now get frustrating.

Hello, well, I am the first owner, and there was not any accident before. Last Thursday, after I started my car, I tried to shift the gear to drive, and the car was suddenly shook. I kept tried to drive it, but whenever the RPM goes up to 2000, the car was bouncing like that I stepped on the brake or so. I was not even able to drive it, and it was even so dangerous to drive. Therefore, I just tried it again at night, and the engine light turned on. I put my car into the fitzgerald Hyundai service center in gaithersburg, md on Friday morning (11/7/14), and I got my car back yesterday. When I picked up my car, I asked them what was the wrong with it, and they told me that the transmission sensor did not lead the temperature. Therefore, I told them that I put my car into the Hyundai service center in fairfax, va three months ago for the exact same problem, and the fairfax representative told me that they could not find any problems with it, so they just reset the software so that it is going to be fine. However, this happened again after few months. A man from fitzgerald told me that this time they update some numbers, so it is going to be fine. I do not know whenever this happens, the engine light turned on, too, and it seems like that it is breaking transmission and the engine together. Since this was not my first time, I reported this to the Hyundai recall service center. They called me yesterday and told me that they do not know the reason, but they fixed it. How come they can fix it even if they do not know the reason" I kept complained about it, and they just told me that they will expand the dates for the warranty so that I can fix it whenever it happens again! they also said that they do not know the next step for it. How irresponsible! now, all I can think of is that this is the defected car. Can you please investigate this" thank you.

When turning on the ignition switch the car interior lights light up. Turning the key to the ignition position, nothing happens. There is no draw on the dash lights or any other lights on the car. It simply has no noticeable effect. I have to turn the key off and on numerous times before it starts. Not starting is, of course, a concern. The expenses from taking it to a mechanic has become a real drain on our finances. However, if it begins to turn off while we are driving, serious injuries may occur. {ref: Chevy cobalt} please investigate this issue. Getting ahead of this could prevent more tragic occurrences.

My 2012 Elantra has failed to start 3 times while it was in park and 2 times while I was on the freeway in a period of 12 months. There was no warning while I was on the freeway. All dashboard lights were on, radio was on and it was until I tried to accelerate when I realized that the car had turned off on me. Luckily, it was in heavy traffic going about 15 miles per hour, nonetheless, it was a pretty nerve wrecking unsafe experience. I was able to turn the car back on after 3-4 attempts. My biggest fear is that the car can potentially turn off on me when I'm going 60+ mph. I drive my kids everywhere in this car and I fear for the safety of my family. I have taken it to the dealer after every incident and their main response is that they cannot duplicate the problem, therefore, they can't fix it. At one point, they claimed that it could be due to carbon build up in the engine so I paid ~$300 for that service which did not help because the car turned off on the freeway several months later. I have even had the Hyundai tow truck from roadside assistance tow my car from my work parking lot to the dealer in hopes that it was proof that the car did not turn on. Tow truck driver confirmed the car did not turn on, then prepped car to place on tow truck bed. He got the car to dealer, then attempted to turn on the car and it did. I tried to get documentation from him but he declined. All I got was a letter that stated that the car was taken from my work parking lot to the dealer with zero details. The dealer is being irresponsible and does not stand behind their product. This is a huge safety issue. I am in the process of pursuing the lemon law and going to BBB for arbitration in hopes that they take the car back. I feel like I don't have an alternative. I cannot, with a clear conscious, sell this car to a dealer or a private party knowing that it is defective.

My 2012 Hyundai Elantra will not start. I tried several times to get it to start and it finally started. All indicator lights will turn on but when I turned the ignition all the way nothing happens. This has happened to me multiple times a year. I had it towed before to the dealership since it's still under warranty but the dealer couldn't find nothing wrong since it started up for them. The issue has only ever occurred when my car is parked.

I've had the following issues with the 2012 Elantra: 1.) the vehicle would not start. This only happens intermittently so it is hard to predict when it will occur and where you will be stranded. All indicator lights will turn on but when I turned the ignition all the way nothing happens. I brought the car to the dealer since it still under warranty but the dealer had no idea how to fix the issue. They had my car for 3 weeks now and still trying to figure what is wrong with the car. 2.) there are also instance where the engine starts but the gear gets stuck in park and cannot switch to other gear. I had to turn the engine off and try to restart. 3.) the battery light indicator briefly lights up at 60 mph.

Yesterday afternoon I got into my car to go to the store, and it wouldn't start. I continued to turn the key to on position, then back off and wouldn't start. Then tried again in then it finally started barely. Again I got into my car to go to work, and it wouldn't start again. I switched the key back off position and on again and still no start. Tried it again 2 more times to start and finally it started up. I had this issue about a year ago about a month after I purchased my vehicle and got it towed to dealership and they found nothing because it started right up for them. Please let me know what to do to get this issue from occurring.

The vehicle in question periodically fails to start. This has been an ongoing issue with this vehicle for several months. At first the vehicle would not start on occasion but has since began having starting issues more frequently. I contacted my dealer and was told of two possible issues regarding a stop lamp switch and a faulty starter. I brought the vehicle in and they were unable to identify a problem. I contacted Hyundai usa and they were unaware of an issue regarding my specific vehicle as there are no recalls for this specific issue but there are recalls regarding this same issue but with other vehicles. I feel that Hyundai is not standing behind their products with their warranty and I do not know on a daily basis if my vehicle is going to start the next time I attempt it.

The car will not start once it is turned off. It could start once and go to the store, and then lock up for a few hours. Eventually it will act normal again ad then start all over again.

I hit my door unlock on my key fab and the doors unlocked from here I proceeded start my car. Everything started but the car. I turned back to the starting position and tried again same results. I waited a few minutes and tried again amazingly it started. What is going on with my car" this has happen before the first time called a tow truck driver and by the time he arrived it started. This was followed by a visit to North county Hyundai in carlsbad, ca. Of course the dealership found nothing wrong. Again what is wrong with my car"

Whenever I try to turn on my car everything turns on except the engine. The lights and everything are fine. The battery tests fine. I have been to the dealer 3 times and they say nothing is wrong with it. It has not started approximately 15-20 times. Based on accounts from others with the same vehicle who have had this problem the engine has also stopped in the middle of driving. Thankfully the issue has only ever occurred when my car is parked, but I'd really rather not risk it happening on the road in rush hour traffic.

The car intermittently will not start. Initially, it would spontaneously start after about 5 minutes of waiting. Later, it would not start until you'd wait about 3 hours. Been in the shop, where I purchased it new, about six times for the same problem. I have to have the car towed in. They say they have no idea how to fix the problem. If this problem happens at night, and I'm stuck in my rural town or at my urban office, my very life is at stake. And I can't get the dealer to fix or replace this lemon.
