Sold a lemon law buyback car without my knowledge. From what I understand I was to sign a document stating that I new that I was purchasing a lemon law buyback car. I did not find out until I went to get the plates for my car and they showed me the title. I contacted the dealership and basically my loss their gain. May 2015 had to replace hose and have A/C recharged costing almost $300 July 2015 had to have both from wheel bearing replaced along with tires costing me $800 June 2016 had to have end links on sway bar and cv joint and shaft replaced. This was under the powertrain warranty still in place on the car check engine light come on and off at random times. When tested said it was an O2 sensor. The back drivers side door lock sticks. So I have to manually lock it for my key fob to lock all of the doors. Today was just told I need wheel bearings and tires on the front end. I believe this car has too many issues being a newer car. I have never had a car with this many issues. Especially a newer car. I cannot get out of the loan because it is a lemon law buyback and the resale on it is horrible. I cannot afford the upkeep on the problems it keeps having. Something is wrong this car.

2012 Hyundai Elantra limited. The airbag warning light appeared randomly at first then remained on constantly. Over time, functionality of all steering wheel mounted controls for cruise control, trip computer, bluetooth, audio system, and horn were lost. I disassembled the steering column to access and remove the air bag clockspring. I tested the connections for continuity with a handheld meter and found none on any terminal. The clock spring failed.

Random no start. Push button start will just make one click sound and not start (this is not a low battery clicking sound). After numerous attempts, the engine will start. One time it took over 10 minutes of pushing the start button on and off to finally get it to start. It seems to happen at random times. It will start fine for months and then just randomly not start. It happened in the past an just started happening again about a week ago.

On November 8th, 2016, saint paul, mn, my car would not start up. No warning signals came on and just made a "clicking" noise". I called Hyundai's roadside assistance when they arrived he told me to try to start it up. The car then came on which was approx. A 45 minute wait. In October 2015- eagan, mn, I was driving on the highway, I felt dizzy, nauseous and had a panic attack. I tried pulling over to the side of the road, the car would not stop despite stepping on breaks, the car kept pulling toward the side of the grass that was surrounded with gravel. I ended up hitting and stopping at a guardrail. The driver side wheel was blown and along the drivers and passenger door was scratched, there was also some front end damage which got repaired. In approx. March 2015- West saint paul, I just got off the highway when my car lost power. I started it up, pressed on the gas and ended up rear ended the driver in front of me. In 2014, maplewood, mn, I was at a restaurant's drive-thru and my car lost all power and steering for about 5-10 minutes. I called Hyundai's roadside's assistance to report the incident. In 2014, eden prairie, mn, I was driving on the highway and my car completely lost power and the steering wheel locked up. I called Hyundai's roadside assistance to report the incidence. About 15 minutes later, the car started up and no longer needed roadside assistance's towing service.

2012 Hyundai Elantra. While attempting to start the vehicle, it failed to start without warning. The vehicle had to be placed in neutral in order to start it. According with numerous reviews there is something wrong with the inhibitor switch (range switch).

My car accelerate on its own without me pressing on the gas randomly. Some days it drives normally and other days I can feel the car accelerating on its own. It was so bad 2 days ago that when I got off the highway it was trying to accelerate into the car in front of me at a red light. I had by foot on the brake and the car was revving to 5000 rpms. I took it to Hyundai who could not find a problem but charged me $250 to clean the throttle body.

2012 Hyundai Elantra randomly will not start. We replaced the neutral safety switch and about two weeks later it did it again. Does not seem to be affected by weather. It has been towed to the dealer twice, but since it starts when it is there, they say they can't replicate the problem and therefore can't fix the problem. I would say in the year and a half that I have had the car it has stranded me 4 times and not on the first turn over another 15. I usually turn the key to the off position and try again. After a couple tries it usually starts.

Car won't start. At first, we thought it's the battery so we got our battery jump starter. But it wasn't the case. Lights and electrical works but the car starter won't turn over. Towed it to the dealer. The following day, went to dealer to check it and the car started without any problem. Dealer's mechanics still hasn't seen it yet that day. There might be some loose wiring or inhibitor switch problem.

My car has been having issues with starting. The problem isn't all the time. I'm not sure what the trigger is, but one or twice a week, it won't start. I thought it was the battery, but it's not. I changed it and still giving me issues. I read online and found that it might be the range switch because people that has this issue had their range switch replaced and no more issue. Before they replaced the range switch, they recommended to put in "N" position before start, which I did and it worked for a while. Now, I have to put the E-brakes on before it cranks. The last couple of weeks, I have issues with locking my car. Neither the electronic push button on the door nor remote works. I had to manual lock it with the key. But this issue isn't all the time either. It only happened 6 times so far.

Car just would not start 2 times in the past two months with no warnings. I got it jumped both times, and it was ok. I had the battery, alternator, and starter checked and they were all ok. I went on a forum about it and many people were complaining about the same issue on the 2012 Hyundai Elantra. Many people were saying it was the range switch that needs replaced. Please recall this. Thank you!

Intermittent start failures. Car fails to start several times a week. Had the battery tested and it checked ok. Seems to be related to the automatic transmission shifter. The shifter seems to think the car is not in park, but is is. Switching it back and forth out of park sometimes works, but not always. Very frustrating. Unreliable. Took it to the dealer and they "corrected a grounding anomaly". failed to start again the next day. Online reports have been very helpful in seeing how widespread this problem is. If Hyundai doesn't recall this problem, their rising reputation will be dashed. I wish I had not bought this car.

I parked my car at home and shut it off. I immediately attempted to restart it in order to adjust the car's position, and found that the interior lights would come on, but not the engine. 3 dash lights--engine, battery, and I don't remember the third one--remained lit. Took it in to the dealership the following Monday (10/19), and they replaced the starter.
