My car has two warning lights on my dashboard. First one is Check Foward Safety system. Second one is Check Smart Cruise Control System. Both of them turned on when I was driving in the middle of a highway. These warning lights activated out of the blue, without any unusual circumstances.I cannot use my smart cruise control system and the car is not able to alert me about forward collision. This issue has already been addressed through a recall for my vehicle's model and year in Korea. My vehicle was produced in Korea and was imported to the United States; however, Hyundai has not issued a recall regarding the same problem in the United States. This is a safety concern, and Hyundai should repair it free of charge, and the company should compensate customers who have already undergone repairs for the repair costs.

Significant water leak which I believe is due to a failure in the door seals. My personal safety is at risk due to a mold issue. The problem has been reproduced and confirmed by the Hyundai dealership-??s service department (multiple visits). This problem is well documented by many individuals in the Hyundai Forums site. The results were the dealership pushes the vehicle back at the consumer without it being corrected. Problem has been occurring since purchased. I recognized the issue in early 2023

I have had to get the horn replaced on my ELANTRA six times the horn goes out and this can be a very big safety hazard as it has caused people to almost hit me because they didn-??t see me and my horn wasn-??t working to alert them this needs to be addressed as soon as possible as this could cause someone to lose their life in the wrong instance

The horn is a known issue to stop working on the Hyundai Elantra. I have had my car for 10 months, and the horn does not work. This is a very big safety concern and I have been told by mechanics and other Hyundai Elantra owners this is a constant issue.

I bought my 2021 hyuandai elantra on September 7 2023 almost 2 months ago and the emergency braking system comes on pretty often while driving my vehicle on the road and freeway so the brakes will lock on me whenever the car is in drive which could cause a serious crash and probably cause damage over time to brake pads and other things this problem has occurred over 5 times within 2 months

The horn stops working. It is not a fuse related issue. It is the horn itself. There are multiple reports of horn failure in this model, 2021 and 2022, on the internet and social media. There are people reporting that dealerships are also seeing a lot of cars with horn failure. This is a serious safety issue. Someone could go off the road into the woods and crash, unable to signal with a horn that they-??re there. Unable to beep their horn to get the attention of a child or animal that is about to run into the road. There are countless scenarios where the horn is important. Cellphones don-??t work everywhere-?? a horn should always work. There are far too many reports of the horn issue for it to not be a manufacture related issue. Please look into this. This could have pretty tragic implications that could otherwise be avoided. I will attach a screenshot from a social media Hyundai group of the 2022 model. I need to get into the dealership to have mine repaired and will do so asap. I-??m just very concerned about the safety of everyone. Some are reporting dealerships are not clear about if the horn issue, which involves replacement of the steering assembly, is covered, while others are saying it is.

So the car will come to a dead stop. Then when I give gas, it will not go for 1-2 sec, then all of a sudden it go at high speed by itself. Even when I brake, it will feel like as if I have stepped onto gas. Very dangerous

I picked up my Hyundai Elantra n-line today 12/1/22. My car was at the dealership for almost 3 weeks for transmission judder (shudder?) issues and they claim to have fixed the issue with a TSB (Technical Service Bulletin) from Hyundai with some snap and cable and additional work that was not disclosed. After picking it up and driving only 3 blocks my car went berserk where all dummy lights went on, the car's engine revved to redline, took off and suddenly the front wheels turned left (due to the avoidance features of the car perhaps) and I was able to pull the emergency break and stop the car. The car stopped luckily and if the e-brake did not work I would have ended up hitting the rear corner of a car and into a house. While the car was stopped, it was still on (unable to be turned off), all lights blinking including dummy lights and the car was showing still in DRIVE mode even though the revving stopped and the car was dead stop. After 10 minutes I was able to turn the car off (push button). Dealership dispatched a tow truck and now my car is back at the dealership for investigation. NOTE: TSB is something that is a known issue from Hyundai but not yet to the level of an official recall is what I was told by the dealership.

Hello everyone. I NEED HELP i have a 2021 hyundai elantra and i have had the same issue for over 10k+ miles and 6 months. My traction control light, (no matter what speed or acceleration/deceleration.) will flicker on and off, make a horrible noise almost as if the ABS is applying but no ABS light comes on, and the pedals will go stiff and the whole car jerks. My 2021 elantra has had a new transmission put into it AND when that didn-??t fix the issue, the wheel speed sensor was replace-?? well if that had fixed the issue, i wouldn-??t be writing this post. after a new transmission, and wheel speed sensors, didn-??t fix the issue the dealership themselves advised me to look into the lemon law being they had no idea at this point what was going on with my car. i have attempted getting my car bought back under the lemon law (Ohio) which my car meets the qualifications being that the issue was brought the the dealerships attention, before the 12 month or 18k (whichever came first) which in this case was taken to them before both. and that my car had been in the shop more then 30 days cumulative (it-??s been 41) and hyundai has denied my request for a buy back, and has told me i need to do more research or get an exterior 2nd opinion. (pretty much a lawyer). they-??ve advised me to -??just keep taking it to the shop and get it fixed-??. the issue is, this does not occur all the time. it is completely random and will do it once in a week and then not again for another 3. but when this happens, it-??s scary. it-??s loud, the pedals go stiff and the whole car jerks. accelerating or decelerating. the dealership will not replace something if they cannot duplicate the issue which is also a reason it-??s taken so long to get any sort of answers. i have multiple videos, the service MANAGER, has rode in my car with me while this issue has occurred and stated himself my vehicle is unsafe, and i should not be driving it. i need help!

Ongoing issues whereby when accelerating the car jerks due to the transmission shuddering. There are many times when acceleration is very slow and the gears slowly shift. Brought this up to the dealership where I bought the car and they keep giving me the run around.

car problems started with back up camera not working, it has caused dash lights to go out, headlights to go out while driving safety sensors to sound for no reason. I have also started having problems with radio flashing and going blank. The vehicle has been checked by Hyundai dealer they did say back up camera bad but no answers for rest of issues.there were no warning lights prior to any of these problems. I still do not know what is really wrong and cannot drive vehicle at night or bad weather for fear of losing headlights. Vehicle is 2021 hyundai elantra with 10,500 miles on it.

Sometimes, for no reason my car will not accelerate (no amount of pedal to the metal will help) and then when it does accelerate, it surges forward at random points and tries to overpower the brakes. This has happened multiple times and the dealer claims they have never heard of this happening. It could cause a serious accident when it happens. I have to find a place to pull off and shut down the car and restart it. This started happening around the 5k mile marker...and now I am almost at 12k.

Two matters: 1) The recall notice "Campaign 216" regarding my 2021 Hyundai Elantra has not yet been remedied nor has Hyundai announce a timeline for a remedy. It is regarding the windshield. 2) Secondly, my horn stopped working 100% and I took it to Hyundai last week and they said a lot of 2021 Elantra's were coming in with broken horns. They ordered me a brand new part that seems as though they redesigned the horn system. It will be replaced this week. I asked if I missed a recall and they said no, the horn problem has not yet required a recall but they seemed to suggest that the horn issue is a real matter effecting their Elantra's. I would hate for other 2021 owners to suffer a horn failure when they actually need it in a real life safety situation. The horn just stopped working. The horn is a safety function and if that is broken what can one do in an urgent matter "yell", not likely. No warning ahead of time...just one day it stopped working with no indicators.

Wireless Apple CarPlay frequently disconnects at random during drives. I-??ve got the latest iPhone update, done every reset in the book, and spoke with my dealership and there is NO solution. It is also impossible to use a wired CarPlay function despite a data-USB input. It is a totally unnecessary move to force users into using this failure of wireless technology. The screen will frequently black out for an extended period of time creating a challenge if you are following the navigation. Additionally, you must tap through 3 warning pages before being able to access the streamed maps or other content again. It is distracting, unpredictable, and continuously more frustrating as neither Hyundai nor Apple have provided a solution that works and instead resort to a -??blame game-?? of each other. Furthermore, both companies act surprised when hearing about this issue, but a quick Google search shows many users struggling with no solution in site! This started the week I bought my car (brand new) and has only gotten worse since.

In the middle of crossing the Verrazzano Narrows Bridge in New York City, the forward collision warning came on and the braking system automatically engaged REPEATEDLY. I was traveling about 30 MPH and had about 4 car lengths between my car and the one in front. The system kept engaging no matter how much room I put between myself and the car in front of me, and as I was in the middle lane of a bridge in heavy traffic I could not pull over. I always keep a good distance in front when driving, but because of the system inappropriately engaging I almost got rear-ended about four times. I was terrified and this continued to happen until I got off the bridge. I use my car mainly on the weekend, and also travel this bridge almost every weekend and this was the first time this happened but it was terrifying and EXTREMELY DANGEROUS!!!!

When using Android Auto via wireless connectivity, and when using Map navigation (tried both Google Maps and Waze), the connection will drop over time. This is a distraction concern for folks using navigation assistance in unknown areas, such as when on business trips. When connected via physical cable the issue does not occur.
