2025 Hyundai Elantra Problems

My 2026 Hyundai Elantra at 3,300 miles experienced a severe frontal impact with 6g logitudinal deceleration due to uncommanded acceleration and complete brake blindness. Depiste this severe impact, neither airbags nor seatbelt pretensioners deployed. At -2.5 sec. prior to impact, the Forward Collision Avoidance Assist data drops off and goes completely silent. There were no warnings or alerts on the vehicle instrument cluster. This proves catastrophic CAN-bus network crash. Because the network crashes, the engine control unit (ECU) became digitally blind and incapable of registering the driver's physical brake applications. EDR telemetry captured erractic signal cascade from -1 sec to 0 sec impact. The accelerator pedal jumped to 70%, dropped to 0% at -0.5sec and teleported to 100% at 0 sec while the engine RPM increases from 2100 to 2400. No human foot can physically strobe a pedal from 70% to 0% and back to 100% in 0.5 sec while the engine RPM steadily increases. Hyundai deceptively using data generated by a glitched, crashed system to blame driver error and evade product liability. Hyundai even claimed non-deployment of airbag system was "appropriate" at 6g longitudinal deceleration for a frontal impact. Damages to the vehicle was estimated at $10,254.67 by State Farm Ins. Police report confirmed via traffic camera footage that my car stopped at a solid red light behind another vehicle, then it suddenly moved forward, just as the driver described. The driver's foot was phyically on the brake pedal, the engine revved up, the car moved foward on its own and crashed into the vehicle in front despite the brake pedal was depressed throughout the entire episode.

The contact owns a 2025 Hyundai Elantra. The contact stated that while stopped at a red light with the precise pressure on the brake pedal, the RPM became elevated, the brake pedal was released, and as a result, the vehicle increased in speed and crashed into the rear of another vehicle. The contact's entire front side impacted the rear of another vehicle. No property damage was reported. The contact stated the vehicle came to a complete stop upon impact and shut off. The contact stated the air bags did not deploy. The vehicle was towed to the residence. The contact stated that no warning illuminated before and after the incident. A Police report was filed. The contact sustained an injured knee, neck, and back and has experienced emotional distress. Medical attention was not received. The dealer was notified of the failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 3,300.

The control panel /radio panel has had a glitch or blacked out screen where it wouldn't come back on for a few hours and I could smell electrical or plastic burning after it did come back on after that the radio started changing channel on its own while screen glitched on and of with saturated static wrench on my dash comes on periodically. The tires pressure unit never has the same amount of air in it according to the gauge. Even though I have made it so that they were all equal several different times. The car feels like it misfires when that it's 9500° outside and you go for any sort of extended drive past 10-15, mi. When the air conditioner is on high, the fuel economy doesn't seem to match the way it's supposed to and some of the programming is missing since the last time it was serviced out of the control panel. Some options that we're supposed to have been there aren't there anymore and I'm pretty sure that when I use the remote to roll down my windows they're all supposed to roll down. Well only one of them does and it doesn't roll it back up the way it's supposed to when that it is foggy out. My camera system says that I'm about to get into a crash and starts blinking at me and beeping and flashing saying that I'm about to crash because my forward safety system or my rear safety system is not working properly. And yes I've let them know about these things My car has less than 25,000 mi on it and the problem started probably 3 months after I got it. When I first got it there was a bunch of little pits in the glass or I want to say hairline bubbles. I don't know what else to call them but they replaced my windshield. They didn't replace the back window that still has them

Car was operating fine, then when we got on the highway, we noticed the check engine light had come on but were unable to get off the highway. The vehicle then began slowing down despite pressing down on the gas pedal. Vehicle continued to slow to about 15mph and we were hit by another car.

The rear driver‑side seat belt in my 2025 Hyundai Elantra will not extend or retract. The seat belt was used under normal conditions, with no excessive force, misuse, or accident that would cause damage. It suddenly stopped functioning and is now completely inoperable. A non‑functioning seat belt is a serious safety hazard because passengers cannot be properly restrained. I brought the vehicle to the dealership, but they refused to repair or replace the seat belt under warranty. They claimed the belt was “overextended,” despite the fact that it was only used normally and has never been involved in any incident that would cause such damage. The dealer’s refusal to address a critical safety component leaves the vehicle unsafe for passengers. I am reporting this issue because seat belt failure should not occur under normal use, and the manufacturer/dealer is declining to correct the defect.

Anytime vehicle is over 35mph brakes fail, vehicle has to coast to a lower speed before you can engage braking. When you attempt to brake at the higher speeds, it click click clicks repeatedly while depressed fully, a mild grind and force against foot from pedal once you coast enough it suddenly will make the sounds less then all the sudden brakes work. Called one dealer (Hyundai sherman oaks CA) and as soon as we said brakes don't work over 35mph were hung up on, twice. The exact same words. Then downtown LA Hyundai basically said we don't accept tow one right now which obviously a non braking car won't drive. Hyundai of America is the ones that called downtown and connected us to them aware of the issues and time frame as we had just purchased the car from carvana and it was this way on delivery. Now returning vehicle to carvana since we can't seem to get a dealer to repair even though it has warranty.

The contact owns a 2025 Hyundai Elantra. The contact stated that while his wife was pulling into a customer's driveway at 5 MPH, the vehicle stalled and rolled back and crashed into a parked Ford F-150. The brake pedal was applied, but the vehicle failed to respond. The vehicle failed to restart. There were no warning lights illuminated. The collision feature failed to engage. There was no fire or airbag deployment. A police report was filed. The driver sustained injuries to her neck and shoulder, and medical attention was provided at the hospital. The vehicle was towed to a tow lot. The local dealer was contacted, but the vehicle was not diagnosed or repaired. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 4,000.

Excessive vibration starting at 50 MPH. Its so bad that you hand becomes numb after one hour of driving. The vibration and shake gets so bad over 65 MPH that it becomes unless for a long trip. Vibration is happening on a 2025 Hyundai Elantra hybrid blue trim after 2,000 milles on a brand new vehicle purcahsed 2 months ago from Platinum Hyundai in Tracy, CA. Took it back to the same dealer twice for repairs. First they did wheel balance, and second time they did alignment. After both repair they said issue was fixed, but nothing changed, as it continues the same level of vibration over 50 MPH. Issue still presist and now Platinum Hyundai dealership in Tracy, CA says that is normal. If you are having same issue, please file complaints with NHTSA, so maybe they can do a recall on the vehicles. Hyundai Corporation of America is useless, as selling defective vehicles! THIS IS PERFECT EXAMPLE WHY I SHOULD HAVE BOUGHT AMERICAN QUALITY MADE VEHICLES, instead of JUNK FROM HYUNDAI!

The contact owns a 2025 Hyundai Elantra from a loaner vehicle program. While driving at an undisclosed speed, the contact started to choke. There was no warning light illuminated. The contact’s hands became very sticky. While continuing to drive, the contact developed a severe headache, and the contact’s hands started swelling, and there were yellow marks on the fingers, bumps on the forehead, and swollen lips. Due to the symptoms, the contact sought medical attention at an emergency room. The dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure. The contact stated that the vehicle was unsafe to drive due to the health-related complications experienced. The contact believed that the vehicle might have been improperly provided with a failing chemical, Xenon gas, which caused the health issues. The contact stated that using the heater caused a chemical reaction, resulting in fumes that were inhaled. The failure mileage was not available.

Component/System Involved: Driver-side rear seat back latch / locking mechanism. The rear seat back would not latch or lock in the upright position. The vehicle and seat are available for inspection upon request. Description of the Incident: During normal use of the vehicle, the driver-side rear seat back unexpectedly moved forward because it was not latched. At the time of the incident, we were not aware that the seat back would not latch or could not be secured in the upright position. The condition was discovered only after the incident occurred. Safety Risk: Because the driver-side rear seat back was not latched, the seat back or attached child seat moved forward and struck a child passenger seated in the rear. This created a serious risk of injury and represents a failure of a safety-related interior component. Confirmation / Reproduction: After the incident, attempts were made to secure the driver-side rear seat back. The seat could not be latched under any condition. A Hyundai dealership later inspected the vehicle, confirmed there was an issue, and ordered parts. A dealer representative stated on video that a component appeared to be missing. Inspections: The vehicle has been inspected by a Hyundai dealership. No collision occurred. The vehicle has not been modified. Warnings or Prior Symptoms: There were no warning lights, messages, or indicators. No prior warning or indication of the seat latch failure was known before the incident. Cause (Best Assessment): UNKNOWN. Based on post-incident inspection and dealer findings, the condition appears consistent with a defective, improperly installed, or missing rear seat latch component from the factory.
