2023 HYUNDAI ELANTRA Recalls, Complaints & Safety

*The engine began sputtering really bad and the check engine light came on. I brought the vehicle to the dealership that I purchased it from and they recommended a fuel system flush and change the spark plugs. I had them change the spark plugs and the check engine was cleared but still sputtered a bit. So I brought it to my mechanic who does most of my work and his diagnosis was that oil was blowing by and to not drive it and have towed to Hyundai cause they've been seeing all kinds of engine problems on Hyundai's and that they since the warranty was 100k miles and I had just reached 104k miles that they may fix it. It is currently at Hyundai dealership being diagnosed. *I was driving on the interstate when engine began shaking in the middle of rush hour traffic making it difficult to pull over to see if I could see anything. *Independent mechanic replicated and said to not drive the vehicle. *Hyundai is currently inspecting the vehicle now. *Check engine light came on after the violent sputtering of the engine.

So back in September of 2023 there was a recall 248 on my 2023 Hyundai Elantra hybrid Limited. This was before I bought the car. I bought it used at a local dealer according to the Carfax and everywhere I look up it says this issue has been fixed on September 14th of 2023. I'm still experiencing the same issue I wouldn't have even known about the recall from before if I didn't have the issue. Now I'm wondering before I take it to a dealer to have it fixed will be covered since it's not fixed. Or no because it was already done supposedly. Just curious thank you

Vehicle screen will shut off while driving and come back on randomly. This is not the first time I have reported it. I have reported it to my dealership, they looked at it and checked the vehicle. It happens so randomly but it's been over 2 years now that this has been happening. Of course when vehicle is getting inspected, it does not happen. I have asked them to update my software on my vehicle, they stated it does not need it but I bought this vehicle on Sept 2023.

My horn continues to short out. It has happened five or more times in two years. (I purchased this car in 2023 and the day I purchased it, I was driving home and found out that the horn had lost sound, I called the dealership and they told me to bring it up the next day. When I brought it up the next day it started working again and they couldn't figure out what was wrong. I then went back home and by that next week my horn was completely not working so I had to bring it back up to my dealership.) My horn not working puts me and others in risk for many of reasons. For starters, it takes away my primary warning and communication tool on the road. I have no way to warn others if they are drifting into my lane, backing into me or any other accident that can happen while driving. I have taken my car to the dealership to get it fixed multiple times. This has been a problem since the day I bought my car. Every time my horn is about to fully short out, it slowly loses its sound and will come and go for multiple days slowly losing sound. I don't have my recent documentation from taking it to the dealership to get fixed, but I have one or two forms from the beginning.

Horn is inoperable due to internal fault. Horn receives power when button is depressed, relay actuates, but horn does not sound. There is no warning system in place for this fault.

This has happened twice. I brought it to Hyundai in Syracuse and they said they could not find a problem. The problem: While driving the car loses power, when pressing the gas pedal the car stops propelling forward. Safety: The car randomly loses power while driving. This could happen when pulling out onto a highway or railroad tracks etc. Problem been reproduced: It has not been reproduced by a dealer. It's happened twice randomly in the 2 years I've had the car. I did bring it to Hyundai in Syracuse NY but they said they didn't find an issue. Inspection: Hyundai in Syracuse NY checked the car for an issue. No police or insurance. Warning/messages: There were no messages or warnings before it lost power.

This is the 7th time my vehicle has been parked and over night killed a battery. It’s been replaced 3 times and this battery lasted 8 months and now my vehicle is dead again. Also you can’t lock your vehicle if the battery is completely dead.

The contact owns a 2023 Hyundai Elantra. The contact stated that while operating the vehicle, the air bag warning light intermittently flashed on and off. The vehicle was taken to the local dealer, who replaced the clock spring on two separate occasions, but the failure reoccurred. The manufacturer was notified of the failure, but no assistance was offered. The failure mileage was 44,000.

On 11/18/ 25 I was driving in highway traffic at 60MPH and car suddenly slowed down to 30MPH. My car would not accelerate no matter how hard I tried. With luck and prayer I moved over two lanes to shoulder...shut off the car for about 10 sec...restarted...and car ran normal again. I When deceleration occurred I saw a notice-symbol light up on the infotainment panel in a black space directly parallel to the total mileage odometer. On 11/21/25 I went to dealer, who checked car out and did not find any problem. I then went online and saw ISLA...Intelligent Speed Limit Assistance...a choice I did not have on my infotainment system. If I had it, I wanted to turn mine OFF. We're scared it could happen again.

Yesterday my horn ceased working again and someone almost side swiped me. This is the 3rd time on my 2023 Elantra. I have 2 Hyundai Elantras that Have had to send to the dealership to replace the horns multiple times. I had the same issue with my Venue, which appears to have had some type of NHTSA action, and feel that the Elantras should be included on said action as they utilize the same horn components.

Low pressure oil light did not come on until the oil drain plug had completely fallen out. Once the light came on, the vehicle was slowed and came to a stop on the side of the highway within 2 minutes. The car completely shut off as if the battery were dead. It had to be jumped in order to put the car into neutral for the tow truck. The safety issue is that the hwy we were traveling on is 70mph. At no time, did we receive a warning until it was almost too late. The car is currently at an auto repair shop as the engine is most likely catastrophic and due to the car having no power, they want to replace not only the engine but also the 12 volt battery and it's module. The low pressure oil warning should have come on way before the plug completely fell out and the battery should not be dead. The mechanics can't even fathom why an engine would fail quickly and drain the battery as well.

The contact owned a 2023 Hyundai Elantra. The contact stated that while driving at night and at approximately 60 MPH, a deer had crashed into the driver's side front door and bounced off and crashed into the driver's side front bumper. The contact stated that he had been thrown forward by the force of the crash, but then he was thrown back when the seat belts restrained him. The contact hit his headrest with force. The contact was unable to stop immediately, and when he had stopped, he observed that the front bumper was hanging from the frame of the vehicle and that he was leaking radiator fluid. The contact stated that the police and emergency services had arrived. The contact stated that he was transported to the emergency room. The contact stated that the police had written a report and had the vehicle towed to an impound lot. The contact stated that he was examined at the ER, and it was determined that he was concussed and had sustained whiplash injury to his neck. The contact stated that the front driver's air bag and side air bag had not deployed. The contact stated that his insurance provider declared the vehicle a total loss. The manufacturer was informed of the failure. The failure mileage was approximately 71,000.

While driving in the rain, car reported "Check Forward Safety System". Error has not gone away multiple weeks later. Hyundai dealer's first reaction was "Oh yes, this happens all the time" (!!) but then refused warranty repair because car is in other than pristine condition, despite being only two years old, still under warranty, with pristine front bumper. Without this sensor, adaptive cruise control, collision warning system, and automatic emergency braking do not work.

I was on a delivery yesterday when this first occurred. I put my car into reverse and proceded to back up when my engine cut off suddenly and a loud warning came on , on my dash by the steering wheel it said ... engine off, shift to neutral and restart. That is what I did and it restarted and I continued on with my deliveries. Then the exact same thing happened again today so I called the dealership and they said there is a recall with the isg system that could be the issue but no resolution yet so there's nothing they can do. In the meantime time I can't use my vehicle for work as im a full time food delivery driver and I have to back up into roadways multiple times a day going in and out of driveways and I can't risk my safety or other drivers safety as my car may turn off in the roadway.

I am reporting a recurring issue with my 2023 Hyundai Elantra where the low oil pressure warning light illuminates consistently during strong acceleration. This is accompanied by a distinct smoky odor from the vehicle. Based on my research into recall 23V-859, which addresses fire risks from a faulty electronic controller for the oil pump in the Idle Stop & Go system, I believe my vehicle is experiencing a related or identical failure. The symptoms strongly suggest that the defective oil pump controller is malfunctioning under load, potentially leading to dangerous overheating and a short circuit.

Vehicle routinely sputters and stalls at slow speeds. This happens once or twice during most times I use the car. This has happened in intersections and on highways at stop and go traffic. The car is not safe to drive. I haves brought the vehicle into the dealer at least three times for this and they have replaced a different valve (don't know what it was) on two of the occasions but the problem continues. I have an upcoming appointment with my authorized Hyundai dealer (the vehicle is still under warranty) and hope I have better luck next time. But a vehicle that stalls on every trip is not safety.

The vehicles horn does not when pressed. Multiple other users have complained of the same issue affecting their vehicle as well.

On multiple accounts did I find my 2023 Hyundai Elantra SEL rear camera not working. Now it displays a green screen and I’ve tested it but with someone directly right behind me while in reverse (not moving) the sensors aren’t going off. This is a huge safety concern for a lot of people who own Elantras

Horn stopped working at at around 30,000 miles. After taking it to the dealership to get fixed it stopped working at 70,000 miles again.

I was driving in completely clear weather on [XXX] . No cars were within at least 100 ft in front of my vehicle. Suddenly the emergency braking system alarm flared and the brake engaged. This could have caused someone tor rear end my car but luckily no one was behind me. The brake also fairly quickly disengaged. I took it to Pearson Hyundai where I had bought the car ([XXX]). They had the car for a couple of days and said they found nothing. They could not duplicate the incident. I would not have wanted to ever drive the car again as is, but the technician pointed out I could leave on the warning but eliminate the braking in settings. I am reporting this because if this happened with a child in the back seat on a road like the 95 it could do incredible harm INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Oil filter cartridge housing is leaking from the top.

The transmission is slipping to the point that I have almost gotten in several accidents due to impatient drives and the car not engaging in gear like it should. Vehicle also has several electrical faults reverse braking system engages at random with nothing in its way,the key not in vehicle warning will sound randomly while key is in vehicle,horn stopped working out of nowhere,while washing vehicle with keys in pocket vehicles key warning system will sound about every 30-60 seconds only when washing vehicle,random front collision warning system with nothing in front of vehicle,seat height adjustment randomly stops working but the rest of the electric seat adjustment works then seat will start working again at random. When taken to dealership for diagnoses the dealer refused to diagnose electrical issues unless I paid out of pocket even though vehicle is under full warranty and all systems listed are warrantied.

The HORN has been replaced on 4 separate occasions through Hyundai under warranty and it can not be fixed. This seems to be a wide spread issues involving the 2023 and 2024 Hyundai Elantra models and there are multiple TSB's at the dealerships. Hyundai has not done a recall or come up with a fix and it renders the horn useless and can cause a major safety problem or accident.

Both high and low horns failed and the vehicle has 61,000 miles. Hyundai said this is a “known issue” to the point that they keep these parts in stock and replace them regularly. This is a safety concern, and required for safety inspection.

Horn has stopped working. A driver was about to change lanes into my vehicle on the highway, and I went to honk my horn to alert them, but it would not work. It is unclear if the issue is with the sensor in the steering wheel, or with the wiring or horn itself. I have continued to test the horn over the next few days and confirmed that the issue is persistent. The lack of a horn meant I was nearly able to avoid an accident by swerving away from the other vehicle. If there had not been a gap in traffic, I wouldn't have been so lucky. The vehicle is available for inspection. I have an appointment with the dealer on Friday 1/3/25 to have this addressed, likely under warranty. No one else has inspected the vehicle at this time, and there are no warning notifications, etc.

While driving at highway speeds the vehicle will suddenly decelerate forcing vehicles behind said vehicle to make defensive maneuvers to avoid hitting our vehicle. We have taken the vehicle to the dealership twice for this condition. This time we were told it was the EGR valve, but it was on backorder. We are now forced to drive this vehicle until it is repaired.

The rear view backup camera doesn’t show. Some days it works most of the time it’s green and distorted. I know it’s common issue so it should be apart of the 21-22 Elantra recall

Horn just stopped working! Fuses are intact. I see this is a consistent complaint for this model. Cannot pass safety inspection and I’ve only had the car for a year

I have been encountering a series of troubling and erratic issues with my vehicle. These problems occur under various driving conditions, including acceleration, steady-state driving, and braking. However, the most prevalent and problematic occurrences seem to transpire during acceleration and braking. During acceleration, I've observed inconsistent behavior. Sometimes, the car shifts smoothly, with minimal torque drop between gears. On other occasions, the vehicle accelerates initially but then abruptly loses all power between gears, resembling the sensation of someone engaging the clutch in a manual vehicle and shifting slowly. This results in a temporary power loss lasting 1-2 seconds, followed by an over-revving and clutch slip, leading to an unintended surge in acceleration. The issues I've encountered during braking typically begin with a chattering noise and vibrations that seem to be an imbalanced or shocked reciprocating mass, I can assume maybe one of the clutches/flywheel . This is often followed by decreased brake pedal linearity, requiring increased brake pedal pressure to stop. This normally results in an unintended aggressive forward jerk just before coming to a stop, akin to someone releasing a clutch on a manual transmission vehicle too quickly when downshifting while the engine speed is too low. One night I went to get diapers for my baby and it was raining and I hit the breaks and the breaks lost control and I crashed into a median wall and my car kept spinning around. Ambulance were called and I was admitted to the hospital with minor injuries.

The vehicle applies automatic emergency brakes when another vehicle passes close by from behind in an adjacent lane, when the Blind Spot Collision Avoidance Assist, feature is set to “Active Assist.” The owner’s manual states that this feature operates when the turn signal is turned on in the direction of the detected vehicle. However, my experience shows that the car applies brakes even when the turn signal is off and the vehicle is driving straight within its lane, without changing lanes. As per NHTSA description automatic breaks to be applied if the driver ignores the warning and tries to change the lane. But Hyundai design applies brakes even if car driven within lane without any warning before applying break

There was a recent over the air software update. Since the update, the speed limit shown on the dashboard, does not match the posted speed limit. This causes the cruise control to change from 70mph, to 55mph. This happened a few times, and always at the same place on the PA Turnpike. Yesterday it did it and there was a tractor trailer behind me. When my car started to decelerate, the driver of the truck laid on the horn because he had to react quickly. I am lucky that he did not hit the rear of my car. This is a safety issue! Also, why does Hyundai feel the need to control drivers speed, especially when there is no government mandate to do so.
