FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

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.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL

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.

BACK OVER PREVENTION: WARNINGS

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

FORWARD COLLISION AVOIDANCE: WARNINGS

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)

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

The vehicle applies automatic emergency brakes when another vehicle passes close by from behind in an adjacent lane, when the Blind Spot Collision Avoidance Assist, feature is set to “Active Assist.” The owner’s manual states that this feature operates when the turn signal is turned on in the direction of the detected vehicle. However, my experience shows that the car applies brakes even when the turn signal is off and the vehicle is driving straight within its lane, without changing lanes. As per NHTSA description automatic breaks to be applied if the driver ignores the warning and tries to change the lane. But Hyundai design applies brakes even if car driven within lane without any warning before applying break

FORWARD COLLISION AVOIDANCE: WARNINGS

Car was breaking hard because of Active Assist despite that no car was in front. It was breaking consistently until I finally was able to disable the Active Assist. Luckily, there was traffic and driving at less than 20mph but this also happened some time last year at the same area where there was no traffic and was going at a minimum speed of 45mph and to have the Active Assist break hard put me at great risk of getting rear ended. I have footage from the dash cam which I unfortunately cannot attach as it's more than the 10MB limit.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

car applies emergency brakes when another vehicle passes close by at higher speed from behind in adjacent lane when the blind spot collision feature in my car is set to "Active Assist". As per the owner’s manual page number 7-46 to 7-52, the collision assist is designed to operate when turn signal is turned on in the direction of detected vehicle. Also, it is mentioned that the audible warning will sound. In actual scenario car is applying breaks even when turn signal is off, driving straight, no lane change. Also, there is no audible warning sound when car applies automatic brake. Owner’s manuals write up is not matching with the issue I observed, and this is very serious safety issue.

FORWARD COLLISION AVOIDANCE: WARNINGS

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.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

My car has 11000 miles. 6 times I have had the emergency braking come on when there have been no cars close to me (4 times by 3500 miles and twice from 3500-11000). One time no other cars even in sight. I have been on the freeway and on side streets, so from 20 mph to 65-70 mph. It is startling and I'm afraid will cause me to get rear ended as it's instinctive to step on brake when this happens. I mentioned this to the dealer I purchased it from at my 3500 and 11000 mile oil changes and they said they couldn't reproduce it and everything was fine. It's only happened 6 times in 11000 miles so it is unlikely the dealer will be able to reproduce. But especially going freeway speeds it is not safe to slam on breaks for no reason and I am afraid of getting rear ended. I was looking online to see if this problem had been reported and someone with the same issue was recommended to report it to this site, so I am doing the same. Thank you.

LANE DEPARTURE: BLIND SPOT DETECTION

On Saturday December 16th my vehicle was parked as I was shopping. When I returned to the vehicle and started it, lights began to light up on the dashboard. They included the rear collision, front collision, airbag, parking brake, battery, tires, blind spot, and others. I called Hyundai and they said that they did not receive any communication from the vehicle stating that there was a problem. The front and rear cameras stopped working and I could no longer tell if my turning signals were operational as I didn't hear the normal clicking sound. It was difficult to turn as the steering wheel was tight. When I first went to the dealership, they refused to take a look at the problem. After filing a complaint with Hyundai, I was finally able to take the vehicle in on yesterday. They also are confused because the initial test showed that there was no problem. They now have the vehicle and are trying to find the cause. This is very concerning because in addition to basically driving blind, according to the manufacturer book, continuing to drive with specific light on could cause engine problems. I also was no longer aware of the speed that the vehicle was traveling nor how much going. The dealership says that it will be several days before they can get to the cause. There was no warning prior to all of the lights coming on and the vehicle has not been involved in any accidents.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING

3 lanes going down to 2 (leftmost closed). I move over to far right lane out of middle lane. No cars ahead of me in right lane. some cars in left lane. In lane for about 100 yards when.... Emergency collision warning appears and warning is made with sound and car pumps to brakes. Nobody was in my lane within 40 yards. Nobody moving into my lane. I have had it slow down and give collision warning when a car moves to right turn lane from right lane and I pass that car. But this time the alert went off and brakes were automatically strongly applied as if I was about to plow into another car without any obvious threat. Dealer checked alerts and no obvious system failures or codes appeared. Turned off automatic braking for now (and as a safety concern, it resets to the default safety braking each time In restart the car). 8:41 AM 7/18/2023
