2024 Hyundai Elantra Owner Complaints

Yesterday May 26 2024 while my husband was driving he had on the air conditioner in our car. Suddenly the warning light went off that car was overheating. This also happened the day before. He was stopped at a light the 2nd time. The car has less then 7000 miles. We recently had the oil and air filter changed at Hyundai dealership. There was no problems at the time of service a month ago. All fluids were normal and everything seemed fine. I don't know why this happened. I googled 2024 Hyundai Elantra and another customer with EXACT same model is also have this SAME issue.

Roughly over a couple weeks, I noticed when pressing on the horn it was NOT responsive when pressing the horn section of the steering wheel, so I took it over to Napleton Hyundai dealership, to take a look at the issue base on what they said, they would have to ordered the part however, it’s on back ordered and would call when it arrives, my issues if the horn is of a safety issue, won’t it be a better quicker response to get the part than get it fix? How many other drivers are having the same issue?

New vehicle was recently purchased at Hyundai dealership odometer reading 8 miles only. Four days later while driving the engine turns off and all dashboard lights start flashing vehicle stops completely in the middle of the road I immediately turned-on emergency lights to make the cars behind me aware. Looking on my rear mirror I notice a vehicle wasn't stopping and I was about to get rear ended so I suddenly wave my hand out, thankfully he passed right by me, and all traffic slowly comes to a complete stop. There was no warning lamps, messages or problem prior failure. I took the vehicle back to dealership for service maintenance I was informed no problem was found and it was a onetime thing they guaranteed me it wouldn't happened again and unfortunately it did.

Vehicle shut off 8 times on my wife while driving. Check engine light did come on with a warning from the vehicle stating a possible issue with our Engine Control System. Shortly after, while ON the roadway, at about 35-40 mph, the car completely shut off. Luckily my wife was going to a church and the church men were able to push her car safely, with our kids inside, off the roadway and into the parking lot. Hyundai Roadside Assistance was contacted and vehicle was towed to Matt Bowers Hyundai in Gulfport, MS on June 5th. During a 12 day stint at the dealership, it was determined that the problem was caused by the open safety campaign (Bulletin 206) and the EGR Valve Assembly was replaced. We took back delivery of the vehicle June 18th, 13 days after the tow/problem.

The car was giving me an issue with the Forward Radar blocked which was coming and going as if the radar was loose. This issue persisted for a week and the error was still coming and going after every 10-15miles of drive. Later after a week the error was constant screen and the radar is still intact to the car. Error on the screen: ######Forward Safety system disabled. RADAR BLOCKED.#####

Towards the end of January, my car computer was reset because the car was telling me that I needed an oil change early and the dealership told me it could just be a computer issue. I then took my car to get an oil change and full vehicle inspection on February 24th, 2 days after that on the 26th I was leaving my school parking lot when the vehicle accelerated awkwardly when I was leaving out of a parking spot, I was then able to gain control back over the speed until the vehicle again abruptly accelerated and jerked to the left sending my car over a curb, deploying the air bag, and completely totaling out the vehicle.

The horn stopped working in our 2024 Elantra. This is a widespread issue (see NHTSA complaints and Reddit posts). I called ahead to verify with the San Leandro dealership that parts were in stock to perform this repair under warranty (prior to scheduling appointment). We arrived and were told that parts were actually not available (after a 3-hour diagnostic). What changed? Hyundai issued a TSB (technical service bulletin) informing dealerships of how this issue is to be repaired (designating a specific part number, while excluding otherwise qualified Hyundai parts). Without TSB, the dealership could have performed this repair under warranty with the in-stock parts. The dealership could still perform the repair, but Hyundai would not reimburse them under warranty. With a[XXX] wife, I was unable to wait and return later for the warranty to cover the repair. I paid $429 to the dealership for the repair to be done with in-stock parts. I left the dealership with a genuine & working Hyundai horn, but it was not covered by Hyundai’s warranty. Hyundai has refused to reimburse us. Two key takeaways: 1 - Hyundai is denying there is a widespread issue while secretly telling dealerships how to address it. The unpublished TSB demonstrates that Hyundai is aware of a widespread safety issue, and is failing to issue a recall. The majority of NHSTA complaints for this vehicle reference horn failure. This is a safety issue. I was involved in an accident where I could not warn another driver before the collision. 2 - The TSB is a mechanism by which Hyundai is refusing to perform repairs that should be covered by warranty. This is a violation of Hyundai’s stated commitment to customers that is not stated even in the fine print of the warranty.

While it may sound bizarre, I can definitively demonstrate that whenever I am present inside a car, the car become very unstable and bouncy and unsafe to operate. Not only does it not steer straight the car also becomes incapable of coasting smoothly and is constantly racing or aggressively slowing down. I can’t be the only anomaly and whatever is causing this could be widespread and is certainly dangerous. I have found it to occur only with the cars which I am inside. I would like to demonstrate this in person if possible to an investigator.

My 2024 Hyundai Elantra limited horn stopped working, almost causing someone to hit me. The car only has 4,000 miles on it. I am extremely lucky I did not get in an accident because of this. Extremely dangerous issue and soon further research its a very common problem with some newer Hyundais. There needs to be a recall before some actually gets hurt!

I randomly get warning lights that my camera is disabled for Lane Departure Warning, Blind Spot Warning, Forward Collision warning, Lane Assist Warning. Each warning message I get comes one after the other stating CAMERA disabled. After a few minutes of driving, all the orange lights disappear and it seems to reset itself to normal. This has happened on three random occassions. I took it immediately to Hyundai of Bay Ridge but they said they were not able to duplicate the problem. I also mentioned to them that my dashboard and Infotainment system constantly dims then brightens for no reason whatsoever. Sometimes, it dims for two seconds, then goes bright again, sometimes it dims for much longer. This happens everyday and it doesnt matter if it is a bright sunny afternoon or an early morning. It constantly dims then brightens. The dealer keeps saying they can't find anything wrong because diagnostics shows everything is ok with their computer. I feel like they are simply sweeping this under the rug because it is a leased vehicle and I am concerned for my safety should I suddenly lose power.

The mounted brake light went out 3 days after my purchase. It worked again after i turned the off the car and turned it back on. However, this kept happening that past two years. I noticed it has to do something with the wiring. It is a dangerous issue and will be sending it to the dealership. This keeps happening while i am driving the car.

The horn on my 2024 Elantra has stopped working. It was intermittent at first, but it doesn't work at all now. I will need to return the vehicle to the dealer for diagnosis. The vehicle has just over 13K miles on the odometer. The horn is an important safety feature, and based on the experiences of other owners of this model, it appears that this is a chronic issue. There are no messages displayed, and I will need to schedule with the dealer for warranty repairs.

When you accelerate & let off the gas pedal, the vehicle still accelerated for 2 seconds after you release the gas pedal. It is like there is a delay with drive by wire signal. This situation can cause rear end collisions & hard panic braking. Please recall this situation to prevent higher insurance cost & increased accidents!

Partner was traveling at or under the posted speed limit, when the front passenger tire "blew." He lost control of the vehicle and was thrown into a home. Car is a total loss. The home is damaged, and he suffered injuries. There were no warning lights or alarms. This was a certified pre-owned, purchased 2 months prior. Milage was at 17737 when the incident occurred, 16242 at purchase. The same tire was reported as being replaced due to a flat by the dealership, before my purchase. The incident is under investigation by the insurance company. Contacted the dealer, they said that "tires blow" at any time, new or used. Instructed us to report it to Hyundai; the insurance company did that, and Hyundai stated there is no known issue with the vehicle. Tire make is Kumho brand, solus TA3 to the best of my knowledge. A police report was filed, and it was deemed related to a malfunction; the driver was not cited. Speed, drugs, and alcohol were not a contributing factor.

When I am using cruise control, my car will just randomly slam on its breaks. I have taken my car into the dealer multiple times, and they have written it off everytime. They have said it’s “direct sunlight” yet I can prove it’s not happening in the sunlight. It happened again today when it was cloudy. It’s also happened before the sun came up in the morning. I have even filed a case with Hyundai directly, and they said if they can’t get it to mimic it, then they can’t do anything about it. But it’s so random, sometimes it happens 50 miles from home, other times it’s 300 miles from home. Always willing to let anyone inspect my vehicle to help solve this issue. I’ve been taking it to my dealer for a full year until I found out I needed to come put it here. It’s random, it won’t happen in the same spot twice. But every time it’s done it, there is never a vehicle in front of me. My assumption is there is a defect with the adaptive cruise control. I’ve talked with Hyundai and they claim they’ve never heard of this happening to anyone, yet when I google it, there are MULTIPLE forums with people stating this exact thing is happening to them. SAFETY issue is it slams on the brakes so hard I’ll go from 80 to 65 before I can get the cruise control off. If someone is behind me when it does this, they will slam into me.when I’m dropping 15 mph quickly, that vehicle behind me will hit me like I’m a stopped object. No warning lights before it happens. This has been happening since I bought my vehicle at 0moled to now where I have 34k miles
