2023 Hyundai Elantra Problems

While driving on [XXX] north near exit [XXX] in rain, at 70 mph Adaptive Cruise Control and Lane Keeping Assistance were on. The vehicle displayed a warning that the smart systems were disabled. The vehicle then began jerking and changing lanes and speed unexpectedly. The steering wheel pulled/jerked forcefully to the left and right and I had difficulty maintaining control of the vehicle. When I attempted to brake, the brake pedal became very hard and could not press down the vehicle did not slow normally. I was able to get the vehicle onto the shoulder and shut it off. After restarting the vehicle, the problem occurred again. The vehicle was towed to Wallace Hyundai dealership in Stewart Florida and is currently being diagnosed. The cause has not yet been determined. Scared me to death. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

The contact stated that while slowly pulling into the parking space the contact lifted off the brake pedal and while costing into the parking space the vehicle experienced unintended acceleration and drove over a curb. During the incident the vehicle sustained damage to the undercarriage. No injuries were reported. The vehicle was later towed to the local dealer who was unable to determine the cause of the fialure. The manufacturer was nofited of the incident. An engineer was scheduled to inspect the vehicle. No further information was available. During the incident the contact suffered emotional stress and fear. The failure mileage was 30,000.

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)

Electrical component with car has been malfunctioning. ADAS system malfunctioning (all the lights on the dash have been coming on in and out at different times) despite turning the car on and off. Video and picture evidence has been collected on different days and times this issue has been happening. Blinkers do not work when this is happening. Concerned for safety while driving. Hyundai Dealership is not helping and blowing me off.

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.

The contact owns a 2023 Hyundai Elantra. The contact stated that while the vehicle was at a full stop, the brake pedal was released, and the vehicle surged forward before the accelerator pedal was depressed.

The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 15,000.

Subject: Safety Concern – Unintended Emergency Braking My vehicle is experiencing a serious safety issue involving unintended emergency braking. While driving on the freeway, the vehicle has unexpectedly applied emergency braking on its own when other vehicles pass at higher speeds. This has occurred multiple times and has nearly caused accidents. This issue occurs consistently during my trips between [XXX] and [XXX] on Highway XXX, typically happening once or twice per trip. I make this drive approximately 4–6 times per year. The problem remains unresolved and continues to occur as of today, April 29, 2026, posing an ongoing safety concern.

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 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

Small crack in windshield caused by a twig less than 4 inches long with a diameter smaller than the width of. Finger. Another small crack in windshield. Do not know how it occurred Contacted local windshield repair business and was advised, per manufacturer they only replace the windshield. Looked online and see that the windshield issue is a known defect. I have an elderly father that lives in North Carolina and I’m gonna have to replace my glass because I don’t want another twig to fall in and burst out my entire windshield when I’m driving down the highway

The tracking number assigned by NHTSA for this issue is 11733456 I am writing to update and escalate my previously filed safety complaint regarding my vehicle. I recently received my car back from the dealership after they informed me that all issues had been repaired and that the vehicle was safe to drive. However, after getting the vehicle back, it is not the same, and it is not safe to operate. The vehicle pulls strongly to the left while driving, which creates a serious risk of losing control, especially at normal road speeds. In addition, multiple safety and driver‑assistance functions are not working as intended. Despite these issues, the dealership insists that everything is “within specifications” and refused to take further corrective action. Because of these unresolved defects, I am afraid to drive this vehicle. I have already experienced a traumatic incident related to this car, and returning it in this condition has caused significant fear and emotional distress. I cannot go through another dangerous situation. I believe this vehicle poses a genuine safety risk to me and to others on the road. I am requesting that NHTSA review my complaint again, including this new information, as the problem persists after inspection and attempted repair. A vehicle that pulls to one side and has non‑functioning safety systems should not be considered safe for normal use. Thank you for your time and attention to this matter. I am available to provide any additional details, documentation, or records you may require.

This has happened twice. I brought it to Hyundai in Syracuse and they said they could not find a problem.

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.

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

The contact owns a 2023 Hyundai Elantra. The contact stated that the vehicle was equipped with an auto light feature that allowed the headlights to turn on at night while the dash light would become dim.

I have contacted the dealer. I am almost ready to get a lawyer. This is the 4th lemon I’ve been sold. Seat belt is installed wrong. Software updates are available and screaming at me but the dealership Will not call Me back. Two days now. Hyundai finance has treated me Disrespectfully. I have error messages when I enter the car. The hood looks aftermarket and about to pop up. The NHtsa website says this car has recalls but not mine?? What ?? It smells like something is burning from the console. The brake collision is calibrated off. I would have a wreck. It’s not safe. Period.
