Huge win for car owners! All TSBs to be made public. The Center for Auto Safety just made the NHTSA (US Government) make public the full text of all TSBs from now on. They are the same organization that has petitioned the NHTSA & filed lawsuits to protect car owners over exploding gas tanks & other major safety issues. Whenever you drive in your car, you are safer thanks in part to a lot of work over the years by this small but very effective consumer advocacy group.

Please take a moment & say thank you by donating $5 or whatever you can to the Center for Auto Safety. Notes: Be aware that there's a significant trend of owners complaining that the Elantra's fuel economy is significantly less than the EPA estimates.

Vehicle wont start at times. This happened when I first bought the vehicle and Hyundai changed the inhibitor switch. Recently started having the same problem of it not starting. Dealer showed me where the reset is so I was able to start it and bring it to the dealer. Again they changed the inhibitor switch. I was told they changed the design of the switch and hopefully I won't have this problem again. Hyundai paid for the part but I had to pay for labor. I'm sure I am not the only one that had this problem.

Intermittently, my car does not start. I turn the key and nothing happens. I try it again. Nothing. I try it again and it starts. It happened when the car was sitting overnight in my garage. It happened after I was in a store for about 45 minutes. It happened after I was in another location for 2 hours. I brought it to the dealer about a year ago when it happened and they said nothing was wrong because it didn't do it for them. (of course, it didn't!) then, after another couple of times of it happening again, I researched and found it was probably some kind of switch. I told that to the dealer and they replaced something which seemed to fix the problem. Now, all of a sudden, it's happening again. I am afraid to drive this car for fear I will be stranded somewhere unsafe one day.

Over the last several years my Elantra has stalled immediately upon starting. It doesnt matter if the engine is hot or cold. Just filled up with gas or anywhere in between. The problem is very intermittent. Usually it would then start on the 2nd or 3rd try but has on several occasions left me stranded requiring a tow. The dealership acknowledged this was a known problem but unless they can replicate the problem, there is nothing they can do. Ive had the throttle body cleaned and all new spark plugs, but its still acting up. I dont want to keep throwing money at it guessing what could be wrong. This began around 10,000 miles and it now is approaching 80,000. Id like for Hyundai to acknowledge there are hundreds of similar complaints and to investigate the problem.

Sunroof shattering: While traveling on the highway in Virginia on 3/25/16 I heard a crack, pop, and then shattering. Pieces of glass could be heard sliding over the top of the car and seen in the back window. No item was seen inside of the car to suggest an outside object breaking the glass. I dropped off the car at the Hyundai service department in white flint.

My 2012 Elantra ltd edition has a keyless entry and push button to start. Recently I am having problem to open the doors or start the cars. Sometimes it starts the engine and sometimes it does not. I am surprised this problem is lot more common in the forum and it has not been taken care by Hyundai or NHTSA. I am missing my work. This is my second Hyundai and this is it. No more Hyundai for me. I paid big bucks for it and no one cares. I have left the message to the dealership in the morning and they have not called me. I had owned many cars before and never had a problem like this.

The vehicle has accelerated on it's own twice now -- today and about a month ago. Both occurrences were exactly the same. They were while parking in my office's parking lot after driving 20-30 minutes on the highway. As soon as I took my foot off the brake it was if I was pressing down on the gas pedal but I was not. When I stopped and put the car in park the RPM shot all the way up and engine was revving as if I had my foot all the way down on the gas pedal. This did not stop until I shut the engine off. I then restart the car and it is not happening. Then, with the car still in park, I gently tap on the gas and it starts again. The gas pedal does not appear to be physically stuck. About an hour later I start the car and try tapping on the gas and cannot reproduce the problem. I see these complaints all over the internet. Hyundai needs to own up and issue a recall before somebody gets hurt, this is very dangerous and scary.

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.

I am literally scared to death to drive this car again in the winter. On Monday, November 30, 2015, we received our first storm of the season. I was driving on almost entirely clear roads until I went over an overpass that must have had a thin layer of ice on it. My car began fishtailing so bad that I had to use both lanes to recover. Thank god no one was in the lane next to me, or one or both would be severely injured. I immediately slowed down to 40 miles an hour and continued to fishtail over every single overpass until the roads actually had some precipitation on them, at which time I couldn't go over 40 mph without the car swaying to the point of no recovery. I have grown up in wi and mn, and I have driven on snowy/icy roads my entire life. I have had small non-4-wheel-drive vehicles (Honda civic hatchbacks) and I have never, ever experienced anything like this. Cars were passing me going close to the speed limit. I was the only one who had to slow down that much in order to remain in control of the vehicle. Prior to this incident in our first snowfall (I just bought the car in July of 2015), I have experienced the rear end "swaying" every time you go over a bump or try to change lanes. It feels like it's just about to swerve but then it recovers, but I didn't ever think it would get this bad. I have no idea what I'm going to do this winter. I do not feel safe in this vehicle. I even added two sandbags to the trunk to try to add some weight, to no avail. This issue has to be addressed before somebody is injured severely or worse. I cannot tell you how close I was to rolling this vehicle on Monday. This vehicle is simply not safe to drive in areas that have the slightest amount of snow or freezing conditions. Hyundai has to be made aware of this issue. This has happened on roads at speeds anywhere from 25 - 65 mph. Highways or city streets.

My car was sitting at my apartment. Went to go to the store and the car wouldn't start. The car would not turn over no matter many times I would try and start it. I had to call my dad who told me to hold gas pedal down and start the car. This happened twice. Took it to the dealership, said they couldn't do anything about it because it wasn't happening at that moment. Car starts to jerk while driving. Started off only in the mornings, then while I was driving home from work, it jerked again this time more aggressive. Have talked with Hyundai 3 times about this issue, said they couldn't do anything about it until they see it happening themselves. I am having to press the gas hard to go at least 50 mph. Yesterday 10/19/2015. I stop to get gas. Full my tank up, get in the car and the won't start again! press my foot on the gas, car won't start. Had to call triple a and they say my battery is low. Bought the car in 2013, shouldn't be happening. Something is wrong with this vehicle and all I get is they have to see it happening. I have taken this car to the same Hyundai dealership in South austin. I bought the car from carmax. I have no idea what else to do.

While the vehincle being in park and trying to start the vehicle it did not start. It does some clicking and after turning on and off the key the vehicle starts. It has aggravated more over the course of these past two weeks and its doing it almost every other time I try to start the engine. The dealer has checked the battery and also taken it to autozone and confirmed the battery is ok but the vechile still does not start. I have an appointment for this coming 9/21/15 for the dealer to take a look at it but reviewing all of the electrical complaints it seems that there is a common trend of affected vehicles with the same issue. Have not seen the experience of the vehilce stalling on me during the highway but because of the daily traffic I take to commute home-work I just hope I dont get into a situation where my safety gets compromised. Do not know how many complaints need to occurr before Hyundai does something to solve the issue and really prevent a major safety one.

2012 Elantra limited fails to start when in park. Battery is fine, all electrical equipment is working. Engine does not crank when the push to start button is pressed. Sometimes it starts after a few tries, but it would not start after trying 10 minutes yesterday. I tried again in the morning and it started without any problem. I search the web and have read that a lot of people are having this problem. People online are saying the problem is the range switch / inhabitor switch. I noticed that the issue is happening more frequently lately. If so many people are having this issue, there should be a recall on this.

I drive in stop and go traffic to and from work. When I push on gas it makes one knock sound. When I let go it makes one knock sound. It's only once, it does not knock continuously. It started making this noise after oil change in January every so often but it has gotten to be every time I push on gas and let go now. I was told I need a transmission flush when I got the oil changed just recently in April. Could this be the what is causing the knock noise? I read reviews on flushes and some say to get it done, others say it has damaged their cars transmission.

My car won't start the first 4-5 times I hit the start button. The first time it happened my car was lower on gas and the outside temperature was very low. I filled the car up, ran at highway speeds for 20 minutes. The next day it was the same situation. I took it to a service garage and they tested the battery and alternator, both were perfect. I thought it might just be the cold, even though I never had these issues at lower temps. The third day it was 30 degrees...same issue. Today was the fourth day, where my car won't turn over. What is going on?? this could be extremely dangerous.
