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 tracking number assigned by the federal safety agency 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 the federal safety agency 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.

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.

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.

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.

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.

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

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)
