Open the full vehicle complaint log (all categories)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.

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)
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.
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 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.
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.
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
