2023 HYUNDAI ELANTRA Forward Collision Avoidance Problems

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.

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)

The transmission is slipping to the point that I have almost gotten in several accidents due to impatient drives and the car not engaging in gear like it should. Vehicle also has several electrical faults reverse braking system engages at random with nothing in its way,the key not in vehicle warning will sound randomly while key is in vehicle,horn stopped working out of nowhere,while washing vehicle with keys in pocket vehicles key warning system will sound about every 30-60 seconds only when washing vehicle,random front collision warning system with nothing in front of vehicle,seat height adjustment randomly stops working but the rest of the electric seat adjustment works then seat will start working again at random. When taken to dealership for diagnoses the dealer refused to diagnose electrical issues unless I paid out of pocket even though vehicle is under full warranty and all systems listed are warrantied.

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

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.

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.

Multiple times driving on highway at posted speed limit and vehicle displays emergency braking system and just comes to complete stop on highway with oncoming cars going 65mph. Has happened 3 times before.

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.

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.

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.

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

As I started driving my Hyundai Elantra, the digital dash and infotainment screen went black and then I got a message that my Hyundai BlueLink Profile along with its settings had been reset. I did not initiate this reset. I never heard anything from the manufacturer about this incident either. This momentarily caused me to lose sight of my speedometer and it reset all my ADAS settings such as following distances, warnings vs active assists, etc.

I purchased a car on December 24th 2022 and from the day I left off the lot there were electrical signals showing that the car was malfunctioning. I told [XXX] (the dealer) what was taking place and the dealership never called me or tried to assist with any problems. For months the signals were coming on and off and my last straw was when my windshield wipers stopped working in the middle of a rain storm after I had just made an in person complaint for the 3rd time about my electrical issues on the car while at the dealership on May 13th 2023. I had just been told there was nothing they could do and I called them upon leaving to tell them I could not see while driving because my wipers were not working. They told me to just go home. [XXX] (New car sales manager) hung up on me 5/17/2023 after telling me I am making assumptions when I was shown proof that the car had issues by the service department when they finally serviced my car about my complaints on 5/16/2023. He told me he was never made aware when I emailed the service manager all of my proof the day prior. I called 5 times before I could actually reach [XXX] who would have been [XXX] supervisor. They even hung up on me prior to speaking to him. I am completely disgusted & I do not feel safe in this car. [XXX] did not want to give me anything in writing that he was saying over the phone. He would not even send me an email. I don't feel valued I feel used. At this point I don't even know or have faith in this company. I am so hurt and as I told him if I were to die because of the issues then maybe he would have took accountability instead of blaming service or anyone else. I even contacted Hyundai corporate and they said there is nothing they can do because the dealership is a family run private Hyundai dealership. I have proof of all records and I will be attaching it. Attached shows different mileage dates, of incidents, official text and emails that were unanswered.

1. Emergency Braking System - came on screen in car - and car took control and began to break 2. I was terrified on two separate occasions because I had no control over my car.... The first situation was when I was on the highway in the slow lane driving approximately 65-70 mph with no one in front of me - suddenly as the car behind me exited off the highway and merged into the off-ramp - my car suddenly began to brake on its own - for absolutely no reason - and then a few seconds later I had control of my car again. The second situation was when I was on a city street in the fast lane (a 4 lane road (2 lanes on each side of the street with a middle verge for people to turn left). I was going approximately 45 mph with no one in front me but there was a car to the right of me (in the slow lane). As I came up to a truck that was stopped in the middle verge lane (waiting to turn left) - my car once again suddenly began to brake - for absolutely no reason - and then a few seconds later I had control of my car again. 3. I took it to the dealership - they informed me there is nothing wrong with my car because they could not duplicate the problem. 4. I do not believe it has been inspected by the manufacturer - I told the dealership they can keep my car for as long as they need to and find out what is going on because the car is dangerous since it is taking on a life of its own. I am not pleased after reading through everything on the internet that apparently this is not an uncommon complaint, yet, nowhere have I seen any resolution to this complaint, so I am now furious that the dealership seems to think it is ok to tell me that there is nothing wrong with my car. 5. No there was no warning lamps prior to the car taking a life of its own

1. False Emergency braking when car from back side passing. Today I was driving in the left lane (lane 1) at ~43MPH. There was no vehicle in front of me and I saw a vehicle applying emergency brakes with a message pop up. At the same time there was a small truck passing me from behind in lane 2 at a higher speed than me. Looks like the system is falsely detecting there is a crash from back and applying brakes.
