2023 Hyundai Elantra other reported problems

UNKNOWN OR OTHER

The vehicle is a 2023 Hyundai Elantra N Line purchased from CarMax in February 2026 with approximately 40,000 miles. It currently has approximately 49,000 miles. The vehicle intermittently cuts off, hesitates to accelerate, and jerks/shudders during acceleration. The specific failed component or system is UNKNOWN because CarMax has not yet provided a definitive diagnosis. The suspected problem involves the engine, fuel/ignition system, transmission, electronic throttle, or another powertrain/control component, but this has not been confirmed. The vehicle’s sudden loss of power and hesitation during acceleration creates a safety risk because the vehicle may fail to accelerate when needed, including when entering traffic, changing lanes, or attempting to avoid a hazard. The unexpected cutting off of the vehicle also creates a risk of being stranded or struck by other vehicles. The problem has been reported to CarMax, but to my knowledge it has NOT been definitively diagnosed or confirmed by a dealer or independent repair facility. CarMax has required a diagnosis before proceeding with further assistance, resulting in delays in addressing the defect. I contacted Hyundai regarding the vehicle and was informed that the vehicle’s original sale/in-service date was October 6, 2023, and that Hyundai has no recorded service history at a Hyundai dealership since that date. Hyundai has not yet physically inspected the vehicle for this complaint. The specific warning lamps or diagnostic messages associated with the failure are UNKNOWN. The primary symptoms are the vehicle cutting off, hesitation when accelerating, and jerking/shuddering during acceleration. These symptoms have continued and remain unresolved. The vehicle is available for inspection upon request. I am requesting that the vehicle be professionally inspected and that the underlying cause of the loss of power, hesitation, and jerking be identified and documented.

The horn is intermittenly failing and was verified by a Weimer Hyundai in Morgantown, WV on XXX. This is a known defect in 2023 Hyundai Elantras and they have issued an extended warranty to address the problem. An absence of a horn is a safety issue as you cannot signal other drivers in emergency situations. It is unlawful to have a horn that does not operate in most states including WV ([XXX]) which is where I currently reside. While a horn is not required by NHTSA , if it is present it must be operable by driver (Safety Standard No. 101, 49 CFR '571.101). For these reasons I am requesting that this should have and should be considered a SAFETY RECALL which is NOT predicated on mileage. By issuing an extended warranty that stops at 120,000 miles Hyundai does not serve those with higher mileage vehicles. It is not fair for a driver to have to pay out of pocket for a KNOWN DEFECT that should have absolutely been addressed as a SAFETY RECALL. Hyundai has been contacted and I was given a case #42976455 and a case manager named Edward. Weimer was incontact with either him or Hyundai directly and they offered to split the cost of $600.00 intead of taking full responsibility. I have no full time job and cannot pay anything (nor should I have to) for a safety issue. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

This is the second time the horn has stopped working. The first time was a year or two ago (records available on request), and both of the two horn units failed. The manufacturer Hyundai replaced them both and told me the issue they were having was the stamped housing of the horn has a seam that folds up and collects water, may freeze, and causes the unit to fail. Clearly they installed two replacement units of the same style because both units just failed again. The way I found out was someone almost changed lanes into me, I tried to honk to alert them to not collide with me, and the horn didn't work. Thankfully I was able to stop fast enough to avoid the collision. I will be taking it to Hyundai for replacement again within the next few days. This needs to become a recall because clearly Hyundai hasn't accepted yet that they need to correct their design of this safety feature.

I purchased a 2023 Hyundai Elantra Hybrid 2023 on December 15, 2023, and since early ownership I have experienced persistent jerking/clunking while slowing to a stop, harsh downshifts, hesitation during braking, and rough transitions between electric and engine power. The issue was first documented around 5,744 miles and continued through approximately six to eight repair/work orders, where dealerships repeatedly described the condition as normal hybrid/DCT behavior while performing software resets, adaptive relearns, and diagnostic checks. After continued complaints, Hyundai Techline became involved and the dealership concluded the vehicle “jerks pretty bad,” leading to a full transmission replacement under warranty. Despite the transmission replacement, the issue persisted and the dealership later confirmed slight clunking during downshifts and discovered a torn engine mount, which was also replaced. The dealership additionally noted that the issue did not occur while driving another Elantra Hybrid or the loaner vehicle, suggesting the condition was specific to my vehicle. I also opened a case with Hyundai Motor America Consumer Affairs regarding the recurring defect and repeated failed repair attempts, but the issue continues despite major drivetrain repairs. Hyundai Motors America Consumer Affairs has not been able to help me with this either. They also didn't provide me with the Federal Agency number when I requested them in order to reach out and seek help from the agencies. Hyundai didn't help me in any way. There were no warnings. They have been able to reproduce the issue but do not want to resolve the issue. I strongly believe no vehicle is designed in a way that it jerks and downshifts in a harsh manner causing distress to the driver/owner.

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.

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.

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.

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.

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

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.

My 2023 Hyundai Elantra has started alerting me while driving that I was going the wrong way down a road. The alert goes something like: WARNING Entering into wrong way detected. This occurs when I'm driving the correct direction. I've Googled the issue and other Hyundai owners have documented receiving the same message. I believe this is dangerous if one is driving someplace unfamiliar and receives this message. It has the potential to alarm a driver into making a U turn and traveling into oncoming traffic.

The vehicle's horn has completely stop working as of [XXX]. I took the vehicle to a toyota dealership because the Hyundai dealerships did not have any available appointments at the time. The Toyota dealership in Ardmore looked at the vehicle to see if there were any issues with fuses and wires. They were unable to find any issues. The dealership recommended I contact Hyundai. I then arranged for an appointment from Hyundai. Several days before the appointment, I was contacted by Conicelli Hyundai. They told me they are not taking any new bookings. I put a bad review on Conicelli's google review. I received a message from Conicelli's customer service department askimg me to call back. I called them back and was told that the service manager will call me back. The service manager called back and I explained that the horn is not working. The service manager told me that they just replaced a horn on someone elses car. He also related that the item is on back order. When I did some google searches for horn issues, I began to see that this is a national problem with their horn failures on various vehicles among different years. I have not driven the car since the horn failure. I believe the horn is on back order because Hyundai is having so many problems with their horn.

My vehicle usually would turn on the warning light stating that the engine oil level is low when I accelerate. The last time I had an oil change, it would turn on when I accelerate my vehicle to merge on the highway. I have had my engine oil level sensor changed out in my vehicle by a Hyundai tech. Immediately after my sensor was changed and I merged on to the nearest highway, it went on again when I increased speed. My vehicle has been inspected by a Hyundai dealer but it could not be fixed. This does not happen when you are at a consistent speed but rather when the car needs to accelerate.

So far since owning this vehicle. I have gone through 7 OEM windshields. I had a 2010 Ford Focus, replaced it with the 2023 Elantra. In 13 years driving the same roads, and only replaced 5 windshields. The windshield thickness needs to be looked into, or what they are made of. Very small rocks are causing the damage, however, what would happen if a much larger rock hit the windshield?

My headlights severely fog up during night driving or during rain, damp weather, or after any contact with water. This is an extremely common problem with 2021-2023 Hyundai Elantra (all trim levels) and causes extreme low visibility at night. Another issue is the horn which is also extremely common on 2021-2023 Hyundai Elantra (all trim levels) and mine has gone out completely twice and been replaced twice. My headlights have been inspected with the issue replicated and was told that it will not require any work because it’s “normal to have fog inside headlights” and no warranty work will be done to fix this safety issue

When I try to accelerate its like it isn't getting gas or there's something preventing it from going. Once it stops struggling it takes off all at once. When it struggles you can feel the vehicle hesitate. It has less Than 5000 miles on it. There shouldn't be a single problem with jt n⁵.

The right back and front windows on this car does not work. There are times when all 4 windows do not work and all 4 doors will lock up and cannot be open from inside nor outside. This is a huge safety hazard. I took the car back to the dealer a total of 6 times. They worked on the car 4 of those six times trying to fix the issue which still exist. They finally told me there is nothing more they can do at this point. I said ok then, so it's clear the car is a lemon, so I would like a manufacturers buy back. They have ignored me. This has been going on since March 5th of this year. I took the car to another dealer for a second opinion and was advised the car is a lemon so I should contact corporate. I was provided the contact information for corporate and so I called and made a complaint. Corporate advised they would have reached back out on June 14th of this year, and to this day I have hear nothing back. I am extremely terrified of driving this car because, what is there is a fire or something, and I can't get out of the car? This car is a real safety issue and all I have gotten from the dealer is disrespect over and over and over. At one point I went back to them letting know again I do not want the car and u was asked by one of their sales person if this is about money. How insensitive. I am paying for a car that I can't even drive. I have parked this car since June 25th of this year and have to now be relying on uber or begging persons a ride. Most time it's very inconvenient. I have tried to speak with the dealer numerous amount of times, but to no avail. I don't know what else to do. Please advise accordingly. Anticipating your favorable response.
