Radio/tape Cd Player problems of the 2012 Hyundai Elantra

For the past several months I have had a reoccurring issue with my 2012 Hyundai Elantra. About 1-3 times a week, my car will not start. All lights, radio, etc. Work fine when key is turned to on/start position but car will not start. It makes one click sound and then nothing. Generally, if I keep trying it will eventually start. Sometimes it takes 10 minutes and sometimes it takes a few hours. Along with this, about once a week my car will shift gears hard. It is an automatic and otherwise shifts fine. I have had routine maintenance completed on time since I bought this car in 2016. I have brought my car to my mechanic several times in the last few months and he cannot determine the problem since the car does not do this regularly. I read online that it could be the neutral safety switch (range inhibitor) so I replaced that. The problem still exists. I contacted the Hyundai dealership from which I purchased my car and they have no answers.

Radio has stopped working.

Car won't start intermittently. Had battery and alternator checked. Lights go on,radio works but car won't start. Car is usually parked in a parking lot or driveway. Weather is nice not too hot or too cold.

All of the issues I am having appear to be involved with the components of/electrical connections to my steering wheel. The red airbag "error" light came on (intermittently at first) about 6 months ago when the vehicle had approx 64k miles on it. Over the next few months, the horn has stopped working (another potentially large safety issue), and the buttons that control the upward volume and radio station browsing have been wavering between working sometimes and not working at all. I did some research about the airbag and horn problems, and there were many stories from other owners of Hyundai Elantras of various years with the same issues. In addition, their experiences with dealers sounded very much like mine in that they (the dealer(s)) want to charge a sum of money to first inspect the vehicle and then charge for the repair(s). Because the airbag and horn problems are potentially very dangerous, I felt the need to report these concerns. I am attaching a picture that I took with my cell phone on 8/17/16 for reference.

I had car jumped 10-12 times, battery replaced ,alternator replaced ,if turn radio on when engine off for 15 minutes car will not start ,this has happened multiple times continue's. Furthermore water leaking 2x's from,passenger side heat vent; leather steering wheel color coming off,1st 4 months of having car very bad smell I had to drive with my window open or got headache's. I was told this was normal,and would wear off. Also sway bar replaced 2's, dealer had told me Hyundai didn't want to put anymore money into my car,and just to trade it in problems continue. I am awaiting answer from company. I am in outside sales therefore depend on my car, ihave to carry jumper cables with me all the time. Iam awaiting answer from the company.

Several weeks ago, on a Sunday, I got into my 2012 Hyundai Elantra in the parking lot of the local kroger and tried to start the car. It refused to start or turn over. It didn't make a sound. The lights, radio, etc. Worked fine, but the car would not start after repeated attempts. I called a friend who came over and jumped me off. I thought this could be related to my battery, but for the next two weeks, I had no problems. This past Sunday, August 24, I put the key in the ignition and it gave a little hiccup, as if it wasn't going to start, but then it started anyway. I made a short trip into town, stopped at the store, came back and the car still started fine. But the next morning, Monday, Aug. 25, it would not start after repeated attempts. My neighbor gave me a jump-off - it took a couple of minutes, but finally the car started. I assumed this was definitely the battery, so I headed to autozone and got a new battery installed. Several days passed, and everything was fine. On Thursday morning, August 28, it wouldn't start again. I tried repeatedly, no luck. I called a friend, who came over to jump it off. Still wouldn't start. I called Hyundai roadside assistance and they had it towed to pride Hyundai, a dealership in batesville, miss. I got a ride to work and, later, I got a call from pride Hyundai. They said the car started just fine. They also reported that the tow truck driver said it started for him as well. I explained the situation and they said they'd look at it. Hours later, I called them back (since it was clear they had forgotten to call me) and they said they'd hooked it up to the computer and found no problems. I asked them to keep it overnight and try it again the next morning. The lady on the phone went out to the lot and came back - she said it started fine for her and again she insisted they could find nothing wrong with my car.

After sitting overnight, vehicle failed to start following morning. Although all components requiring power (windows, headlights, radio, interior lights, etc. ) seemed to be functioning ok, jump started vehicle, and it started immediately. A few days later problem reoccurred; let vehicle sit for some time, and vehicle then started immediately (no jump start). Today problem occurred yet again (waiting to see if vehicle will eventually start). A quick review of online forums indicates a possible issue with the shift interlock, or perhaps a faulty rain sensor. As an aside, a longer-term sporadic, presumably electrical, issue also exists with the passenger side front window. The window will go down without issue, but it often takes multiple attempts from either the passenger side or driver's side window control to get the window back up.

Within the first year of owning my 2012 Elantra, I started having an issue with the car not starting. Dash would light up normally, and radio, etc worked fine, however the engine would not try to turn over at all or make any noise whatsoever. The problem is that the car is not sensing that the car is in park. The dash will normally display p (for park), however in these instances the dash is blank where the transmission position should be displayed. The shifter is also stuck in park so I can not move to any other gear. In order to resolve this issue, I have to use the shift overide and move the car out of park and then back into park. The dash will then display the p, and I can start the car normally. I have taken to the dealer on two occasions, and their computer diagnostics don't detect any problems. They said if they can't repeat the problem then they won't change out any components. This is frustrating because there is no way I can get it to the dealer when the problem is occurring.

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 hyuandai 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 iresponsible 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.
