Reporting on 2020 Hyundai Elantra. I have owned since 2023, my car is currently at a Hyundai certified dealership for it's 3rd transmission in the three years I have owned it. All 3 transmission were inspected and then replaced by Hyundai certified technicians. The Safety aspect is the inability to get you vehicle off the highway.

Currently, there are 30,564 miles on my vehicle and I am the original owner of the vehicle since early 2021. This is a continuous intermittent problem that can occur at any time when trying to accelerate the vehicle. The vehicle could be moving down the road and you go to accelerate and the RPM's drop dramatically, giving you no power. The same thing has happened when trying to accelerate from a stop. The vehicle would start to accelerate and then all of a sudden the RPM's drop, giving you no power. I have had the vehicle to the dealership for this problem and I am being told that they can't do anything about it because they can't duplicate it. If this happened when it was necessary for me to get out of the way of a vehicle, an accident could occur, resulting in sirius injury or death. Also, there were no warning lights or check engine light that came on at any time when the problem presented itself.

Unknown and about 4 months ago my headlights stopped working one would go out I’d replace the bulb then the other goes out then a different bulb in my headlight would go out I’d replace it and it would go out again then the connectors were unresponsive then my height beams won’t engage leaving me with little to no light in order to operate my vehicle at night and oddly enough they would disengage while driving leaving me visually impaired while driving

The manufacturer's Executive Case Management has ceased communication after verifying a total headlight failure. Despite providing evidence that the vehicle is grounded 150+ miles from home during a snowstorm, Hyundai is refusing to authorize the remedy outlined in TSB 20-BE-004H. This non-responsiveness to a verified safety hazard (Invoice #XXX) is actively endangering the driver and the public.

I have a 2020 Hyundai Elantra Limited that was purchased new in December of 2020, has 17,764 miles, and no damage. At the end of May/early June of 2026, the car gave warning messages for the following: check forward collision avoidance assist system, check lane keep assist system, and check high beam assist system. The car was inspected by the dealership, from which it was purchased, on June 29, 2026. The technician report says error codes C1604 and C1606 were found and that the car required replacement of the front camera system at the cost of $1991.49. Front camera failure negates the ability to use the advanced safety features of this car. These features are so important to alert and, more importantly, assist the driver avoid accidents and improve all motorists safety. I have read numerous complaints depicting the same problem with this front camera system. Hyundai issued TSB 20-BE-006H due to multiple problems just like the one that happened to me. I have corresponded with Hyundai about this situation and my concerns on why a car with this few miles and no damage had a failure of this magnitude. They are unwilling to assist due to the warranty expiring 6 months ago. For components this important to the safety of all drivers, I would like to see a recall established to hold Hyundai accountable for faulty components. Safety should not be limited by a warranty and last longer than 5 1/2 years. Than you for your consideration.

The contact owns a 2020 Hyundai Elantra. The contact stated that the vehicle unexpectedly turned off while driving 25 MPH on a local road. The engine symbol was displayed. Additionally, the battery was drained. The vehicle was taken to an independent mechanic, and the battery was replaced three times. Additionally, the computer was replaced, and the contact was informed that the powertrain system had failed. The local dealer was contacted and confirmed that there was no extended warranty on the vehicle. The vehicle was not diagnosed or repaired. The contact called the financial institution and the dealer who sold the vehicle about the warranty. The manufacturer was not notified of the failure. The failure mileage was approximately 70,000.

On January 1, 2025, I discovered my vehicle had been stolen after finding broken glass in my driveway and immediately reported the incident to the police, who arrived within approximately 20 minutes; neighbors later provided camera footage of the theft, and I also observed other nearby vehicles with similar damage, including a broken rear window and another Hyundai Elantra that appeared abandoned. The following day, police informed me the vehicle had been recovered, and upon inspection I found the rear driver-side window completely broken and the ignition area under the steering wheel damaged. Couple months later I received a recall notice for the antitheft system on my 2020 Hyundai Elantra (VIN [XXX] ). When I brought the vehicle to the dealership on April 1, 2026, I was informed that the recall cannot be completed unless an additional part is replaced, at a cost of approximately $1,178. This part was damaged during a prior theft incident. My vehicle was stolen last year and later recovered, and it sustained damage during that incident. However, I understand that safety recalls are required to be repaired at no cost to the owner under federal law. I am concerned that I am being asked to pay for repairs in order to complete a safety recall, and that my vehicle remains vulnerable without the recall remedy being performed. I am also concerned about the safety and legal compliance of continuing to operate the vehicle under these conditions. I am attaching supporting documents as proof of the vehicle theft, along with the reports provided by the dealer.

There is a grinding in my steering column, worse at lower speeds. I have spoke to Hyundai about this and several other shops and they said this is a common recall for Elantras and there is a barring that is in the recall. However, my VIN is not in this common recall. If this is a common recall on Elantras in my year range, wouldn't ALL Elantras have the option to have to corrected not just a select few? Per Hyundai dealership, They know exactly what it is and it should be on a recall list my VIN just showing it so they can not correct the problem. This started before I purchased the car from a friend and she was told the same thing when she checked into it before.

This complaint documents a recurring automatic transmission failure resulting in three complete vehicle shutdowns during active operation — two at highway speed and one in an active turning lane. The most recent failure occurred within 15 minutes of the vehicle being released from an authorized Hyundai dealership in College Park, Maryland, whose general manager admitted in a recorded call that the vehicle was released knowing the transmission was unrepaired and unsafe. The first failure occurred in 2025 on a highway with no prior warning. The vehicle was towed to the dealership, where the transmission was confirmed defective and repaired under warranty. The second failure occurred in January 2026, again on a highway with no warning. The dealership held the vehicle from January through May 2026 — four months — with no updates despite multiple owner inquiries. In April 2026 the dealership confirmed the transmission had failed again and was seeking Hyundai corporate authorization for the warranty repair. On May 21, 2026 I was told the vehicle was ready and the transmission had been fully repaired under warranty. This was false. On [XXX], within 15 minutes of leaving the dealership, the transmission failed a third time, completely shutting the vehicle down in an active turning lane with no warning. The general manager at Hyundai College Park later admitted in a recorded call that the transmission was never repaired and the vehicle was released only to recover the dealership's rental car, with full knowledge it was unsafe. All three failures were confirmed by the authorized dealer. Component is available for inspection. NHTSA investigation and recall consideration requested.

I am submitting this complaint to document ongoing brake related concerns on my 2020 Hyundai Elantra that may affect vehicle safety. Since April 2024, I have experienced repeated brake rotor warpage that causes vibration during braking, reduced braking consistency, and a noticeable change in stopping behavior. These symptoms raise concerns about braking performance and overall vehicle control. I reported the issue to Hyundai Motor America and followed their required warranty process, including an inspection at High Desert Hyundai. The dealership indicated the condition should be covered under warranty, but I was charged twice for what should have been a no cost warranty inspection. HMA later denied warranty coverage based on an undefined claim of “outside influence” without providing any criteria, explanation, or evidence supporting that conclusion. The denial prevented me from understanding the basis of their determination or how it applied to the brake condition. HMA then directed me into the BBB Auto Line program under case number HYU2605570 as the next step for disputing the decision. Throughout this process, Hyundai did not provide any additional information or documentation explaining the cause of the brake condition or addressing the safety concerns I raised. Because braking performance affects stopping distance and vehicle control, I am reporting this issue to NHTSA so the agency is aware of the repeated brake vibration and rotor warpage, the inconsistent braking behavior, and the lack of clarity from the manufacturer regarding the cause. I possess all invoices, communications, photographs, and documentation related to the inspections and interactions with the dealership, HMA, and BBB Auto Line, and I have maintained these records since April 2024. I also filed a complaint with the NHTSA for this same reason on February 4, 2025, complaint no. 11638352, for reference.

Within a matter of a few days my car has been stopping by itself. The car was smoking and stopping in the middle of the highway, my dealership is proving me with a new engine but is trying to have me come out of pocket for an fuel injector, please help !

I see there was a P0420 error code related to catalytic converter oil consumption recall, but when I put in my VIN it said no recalls. This is for a 2020 Hyundai Elantra 2020. The problem comes and goes and was able to be reproduced or confirmed by a dealer Hyundai. The warning lamps, messages comes on frequently and was reportedly fixed charges $2000 for a sensor. I the code and it is all over the internet that it is a recall.but does not show up with VIN.i need assistance with getting this fixed at the dealer

A few weeks ago, I was driving home on a 3-Lane local state route here in NJ from a family outing on a rainy dark evening when a large portion of the body paint from the hood flaked / peeled off and somehow got stuck under the drivers side windshield wiper as they were on during the rain at highway speed. It was a large enough piece (at least 3" wide) , to not only get stuck under the wiper, but create a serious issue for me to see out the windshield where the wiper wouldn't clear my vision out of the windshield. I managed somehow to safely pull to the side of the road and get out to inspect what it was.. I was able to remove the large piece of peeling paint from under the wiper but it did ruin the edge of the wiper blade which made for a treacherous drive home and I had to replace the wiper at a later date. The paint is peeling from all over my car (Hood, Pillars, Roof) and I've done my best to get all the loose pieces off but I'm afraid to drive it anywhere with the thought more paint will peel off with the wind & get carried to someone else driving behind me. My Hyundai Elantra is a 2020 and has only 48,526 miles currently. I contacted my local Hyundai dealer who advised me I am "Out of warranty for paint coverage" and suggested I further open a case with Hyundai Corporate, which I did, and was assigned a case manager who requested I take it back to my local Hyundai dealer in Avenel, NJ (Sansone) and have a service advisor/technician take pictures and submit them to Warranty Services for a "goodwill repair". Hyundai came back with a "DECLINED" status from it being "Out of warranty caused by the time in service and mileage of the vehicle" and "no goodwill assistance is being offered at this time". The estimate from Hyundai claimed it would cost approx $6,500 to have the car repainted according to the service printout. The dealership and Hyundai are both aware of many, many vehicles that entire pieces of paint are just peeling / falling off several colored cars.

Paint is peeling off vehicle.

I no longer have this vehicle, as I traded it in once I was able to lower some of my negative equity. During owning the 2020 Hyundai Elantra, a deer it the side of my vehicle and knocked me into the center of the road while I was driving. No airbags had come out, nor was any sensor activated. About 6-8 months later, I was driving down the same road and a deer had run across the road. The forward collision sensor did not alert me (I was paying attention to the road, but would have absolutely heard it), and my airbags did not deploy. My car suffered over $9,000 in damage and I had a concussion.

On [XXX] at about 1:40 p.m. I was driving to work, and got distracted and had a front-end collision with a tree that was about 1-3 feet next to the side of the road. Extensive damage to the vehicle, and personal injuries occurred (mild concussion, stress fracture of left forearm, bruising/abrasion on ride side torso, sprained left thumb, and abrasions on head). Both the driver and passenger airbags did not deploy which contributed to me almost flying through the windshield. The emergency responders and tow truck operator were very surprised I wasn't in critical condition or dead and noted that the airbags failing was a serious issue and I was lucky. This was reported to the manufacturer and geico insurance on December 20th, and I am currently awaiting to hear back from both to get the inspections scheduled. The vehicle is currently located at OC's Auto at 598 Armistead Blvd, Holt FL 32564. I have already signed papers giving permission for inspections by the insurance company if they request it, but currently inspections haven't been done yet to determine damage estimates or to investigate the airbags.

Every time I go up a hill the slippery road light comes up. It’s hard to drive straight. I have to drive under the speed limit going up hills. Sometimes it won’t even let me park. I hear rattling when I drive over a certain speed limit. When I brake I feel the brake pad pushing back. And now my wheels are making noise when I turn them.

I was in the inside left turn lane turning left and as I was turning my steering wheel my car was not turning, it was continuing to go straight. I hit my brakes so I wouldn’t crash into the car turning next to me and then my wheels finally turned as I was braking so it caused me to burn the tires and swerve. I’m not sure if any lights came on as I was trying not to crash into the vehicle next to me. I have an appointment for the dealership to look at it.

Since I have bought my Elantra, I have had problems with the seatbelt alarm going off, when nobody or, maybe just a purse or wallet in the seat on occasions. Either way I shouldn't have to utilize passenger seatbelt to keep from beeping; when there is no passenger riding at the time of warning beeps.
