Automatic Emergency Braking Problems of Hyundai Tucson - part 2

All of a sudden my 2024 Tucson gages indicated emergency braking for about 1 to 3 seconds and the front end went down as though I was stopping (scared me ). I was so happy no one was behind me. No one really behind me or to my left. Only one car to the right of me in another lane. Also, had to replace air bag at 6176 miles.

I have had two incidents where the emergency braking system applied itself when there was no reason for it to do so. Both times there was a car in the distance, over 20 feet away that was slowing, and I was slowing as well. The second time it happened, it was with great force and I was fortunate that the car behind me was able to brake in time and avoid rear ending me.

Forward collision emergency braking. Have had this happen on 5 different occasions. Very dangerous. The vehicle without warning slams on the emergency brakes and issues a warning. Took into dealer and they could find no error codes and did nothing. First time this happened I thought maybe a bag or something flew up and obscured the forward facing sensors. Pulled over and checked nothing. Then 3 times it happened within 5 minutes. Pulled over and sensors looked fine no dirt or anything on the sensors. Can not drive car with this and so have been disabling the system except for a warning tone. Today it activated it again. Usually when I approach something the sensors turn yellow and then red when getting real close to an object. But today when it activated when not close to anything and driving down the road all the forward sensors activated with the warning but it was gray. (not yellow or red) since I had it on warning only the brakes did not activate. This is very dangerous and unless you disable the automatic emergency braking could lead someone to plow into the backend of the SUV and it evidentially does not cause error codes. Yes,someone can contact me concerning this. This has happened multiple times. Intermittently.

While driving 70mph on the freeway, the car’s emergency braking assistance activated twice for no apparent reason. This is very dangerous at such high speeds and could result in a serious accident if cars are following close behind. This car has not been inspected for this issue. A google search of this issue revealed many similar complaints that have not been addressed or taken seriously. A possible related warning message about “blocked forward safety” has appeared a few times in the last week.

-auto start/stop "feature" since there is no way to permanently disable this feature I forgot that it was on. While stopped a stop light I was unable to move when the car behind me could not stop due to the wet roads. If the car behind me was unable to swerve in time I would have been rear-ended. By the time the engine started the car behind me was in line with my back seat. No amount of gas saving is worth being immobilized essentially in a emergency situation. - forward collision avoidance is way too sensitive, in the same trip as above a car hit their brakes approximately 6 car lengths in front of me to turn into a parking lot. The car in front of me did slam on their brakes to make the turn. As I took my foot off the gas to slow down the "safety feature" activated, applied my brakes and almost caused the car behind me to rear end me. I was going roughly 45 mph and the car behind me was roughly 2 car lengths behind me when the "safety feature" activated. The sensitivity of this system is way too high and will wind up causing more accidents then it prevents.

While driving approximately 75 mph in the passing lane on highway, the vehicle suddenly automatically brake. Pulled back into the right lane and didn't really understand what happened. Next time I pulled out to pass and had a car on my right hand side it did the same thing. Pulled back into right hand lane and stayed there for quite some time. I then turned off the all around sensor @ and it didnt do it again but as I got closer to home the warning light came on and a message popped up. It now has the triangle caution sign on and the picture of car icon in amber. I had driven the car from my home for about 50 miles and parked car for two hours, the drove back toward home for about 20 miles when the event happened. It was dangerous and makes not want to use any of the "assist system's" going forward. I plan to wash the car today to see if the lights will go off- if they don't then I shall call dealer on Monday. This occurred on Saturday. Ill be washing car today (Sunday). If I had anyone driving closely behind me, I for sure would have been rear ended.

My car automatically braked in the middle of an intersection and caused my vehicle to be rear-ended. This was the third time automatic braking engaged when it should not have been. In the most recent incident on 30jan2025 I was injured and had to have medical attention. I googled automatic braking and there were many reports of automatic braking being deployed when it should not have been.

While driving my 2023 Hyundai Tucson phev with limited trim the emergency braking function activated for no reason at all. This has happened 5 times during the last 9 months and each time it was about the same conditions. Road was dry my speed was from 55 to 75 mph it was during daytime hours and no cars were in front of me or on either side of me. 3 of the times there was a car behind me that had to check up I guess because my brake lights came on. I reported the problem to the dealer and was told no other owner has ever reported than problem. Instead of preventing an accident the activation of the emergency braking system in this situation could have caused an accident with the cars around me reacting to my sudden braking at high-speed resulting in a chain reaction.

I was driving on a highway at 75 mph, on a clear day, with perfect visibility and driving conditions and my automatic emergency braking engaged. I was on cruise control with no one in front of me for approximately half a mile. There were cars behind me, so I had to swerve into another lane to avoid being rear ended. There was a sequence of beeps. If there were warning lights or messages, I was too busy dodging to see them. There may have been a squiggly line that came up, but I am unsure.

There is a camera mounted on the steering column that is "supposed" to be a safety feature to tell you when you are not paying attention to the road. It gives you a picture of a coffee cup and says "consider taking a break" along with repetitive beeping. Unfortunately, if you wear sunglasses (mine are prescription), a hat, are too short or too tall it can go off repeatedly. It is extremely distracting and causes you to take your eyes off the road to see what's going on. On a 350 mile trip that I make often, it has gone off for a solid hour every 4 minutes! it averages about 30-40 times in that 5 1/2 hour trip. It also mutes anything that is playing through the infotainment system including directions. I have asked the dealer who says there is nothing they can do and it is a known problem. Hyundai says it is functioning as designed. I have also filed a report with Hyundai. A safety feature that causes distractions is not a safety feature! also, the emergency braking has almost caused me to get rear ended on a number of occasions. I have been in the process of slowing down or braking when the emergency system kicks in and almost throws me through the windshield. Cars following at a reasonable distance have to slam on their brakes to avoid hitting me. Isn't this feature supposed to help you avoid accidents, not cause them.

A week ago, I was driving my 2022 Tucson hybrid limited on the highway on my way to work around 7:50 a. M. It was a bright day, good weather. I was in the center lane when my car suddenly braked hard and came to a stop on the highway! my foot was still on the gas pedal, but the automatic emergency braking light was on. I panicked because I had no control over what the car was doing. Thankfully, I was not rear-ended and didn't cause an accident. I put on my hazard lights, shifted into park on the highway's center lane, then back into drive and it seemed fine. There was not really any traffic in front of me that I remember, but there were some cars on either side and behind me that had to swerve around me. I don't trust this car anymore. It is going to get me or someone else killed. I took it to the dealer 2 days ago and the initial inspection didn't show any problems or error codes. They told me I could have it back since there didn't seem to be a problem or they could give me a loaner car and keep testing my car. I have a loaner. I hope they find something wrong with the car, otherwise, I am afraid of my car getting me or someone else killed. I am especially scared after reading about all the others here who have had this same issue.

While driving in light traffic, speed at 45 mph, my Tucson alerted me with a beep, steering wheel vibrated and a red alert on the dash was present for about 3 seconds then the speed automatically slows down to 15 mph all on its own while my foot is still on the accelerator. This has occurred at a minimum 6 times. I purchased this vehicle brand new and driving it off the lot it had 22 miles on it. I've taken it to a Hyundai dealership, and they can't figure out what it wrong with it. I feel very unsafe and unhappy now of this major safety concern. This has high probability of getting rear ended. I see that this has been occurring with various years of Hyundai and am wondering why there has not been a recall on this issue. I owned a Hyundai prior to this 2024 (tucson 2011) and it was wonderful. This is highly concerning for me, and I am not confidant driving this vehicle and will more than likely trade it in for another vehicle. Can someone please research this issue with the automatic emergency brake system. This can autonomously go off whether you are in traffic, highway, street or completely zero vehicles or pedestrians around.

Automatic emergency braking deployed without any external threat. I was driving 55 mph on the freeway and the automatic emergency braking engaged. The dash lights flashes, there was an audible alarm and the car braked. There was no danger in front of the vehicle and this action put me at risk of being hit from the rear by the car behind me. My safety was put at risk as my acceleration was greatly diminished compared to the traffic around me. There was no warning of the problem prior to the failure. It has not been confirmed by the dealer.

While driving n on hwy 75 in dallas, I was traveling at posted speed- 70- in the 2nd of 4 lanes when I was passed on either side by cars 10-15 mph faster than me. They passed almost exactly at the same time. This confused the cars auto breaking feature. The lane ahead was clear for over 100 yrds. My car braked hard and beeped a warning. There was no reason for the car to do this. This is the 3rd time the car has braked on the hwy when it was not necessary. Previously, I assumed road trip bugs on the censor caused the issue, that could not have been the cause this time. This is also a concern because the spyware in the car is sold to insurance companies apparently, as bad driving behavior which may affect my rates.

On Aug. 23rd, I was driving on the highway at 70mph when the emergency braking system deployed. The dashboard warning light flashed and the brakes were applied for approximately 3 seconds, and then the car returned to normal. This occurred 3 times in the span of 18 miles. At no time was there ever a vehicle directly in front of my car. Fortunately I wasn't being followed closely by another vehicle, or there would have been an accident. I took the car into the dealer and was told that they would run a diagnostic, which they did. They also drove the car for 3 miles. They were not able to replicate the problem, and found all codes to be normal. I feel like this car is an accident waiting to happen.

Sudden hard breaking for no reason. It's happened 3 times when in cruise control. If a car had been close behind it would have caused a wreck. I've had the vehicle just over a month.

2023 tuscon limited gas - multiple instances on vehicle forward collision warning system activating with alarms noted but no activation of emergency braking while sitting at stop light with cars in front and back that are not moving. Radio system going to show surround view and in some cases only front view even though at stop light. Biggest issue this weekend while taking a curve while merging onto another freeway the emergency braking system activated for no reason. First time occurrence. No one beside me or in front of me for some distance but did have someone behind me. It was a quick activation of the brakes and then release, I would say 1-2 second engagement. If had been longer and brought me to stop would of been an accident. I am taking the car to westlake Hyundai to investigate this week and will report. Also having dealer investigate premature driver seat excessive wear. Car has 15. 5k miles on it. I am concerned as this car is exhibiting same issues that my wife's 2018 tuscon had that ended-up being successfully lemon lawed. I am also seeing way to many similar complaints and Hyundai needs to figure out what is going on with their emergency front collision sensing system and issue a fix or recall.

While driving my 2024 Hyundai tuscon limited, 55 mph in left lane on highway, with no cars directly in front of me and only one car alongside me in the right lane, my emergency braking red warning light suddenly came on as the car abruptly braked hard for no apparent reason. Within several seconds, I regained control of the car. Luckily there wasn't a car closely following me, which thankfully probably averted a collision. I have since made an appointment with the dealer from whom I purchased the car and am awaiting the results of their inspection of the car.

While my husband was driving on the freeway and I was a passenger in the front seat, the automatic emergency braking employed while we were driving about 70mph. We have no idea why. There was no cars breaking around us, and no reason for it. There was plenty of space between us and the car in front of us. The car behind us had to swerve to the other lane to avoid rear ending us. My husband had to grab hold of the steering wheel hard with both hands as the sudden breaking made our car swerve to the side. It was terrifying. Then about 5 seconds after his happened, it happened again.

Driving down highway going about 65 miles an hour no hazards in front or behind me suddenly red flash emergency breaking lights and car slammed on brakes resolved on its own in about 3 seconds but could have caused an accident.

My Tucson is applying automatic emergency break without a reason. It happened to me 3 times in a week with my Tucson hybrid 2024 nline, it was scary and I was on freeway at 70+mph and couldn't capture the warning as it popped out for only 3 sec. I see no cars around when this happened and when I checked few forums I see this as a common problem in Hyundai vehicles in recent times and feeling scared. I was lucky enough last week as there is not vehicle behind me when breaks applied automatically.

I was coming back from the mall on the highway doing 50mph and my truck started losing power which it has done before but this time the emergency brake came on and my truck stopped in the middle of the highway on a Saturday. Thank god no one was following me close because that would have caused a bad accident. And also sometimes after I stop at a light or stop sign my brakes harden and I can’t press them down if that makes since and all my needles move back and fourth while the engine is making a noise but the car is still in drive but will not move. I have to hit the button to turn the car off and restart it and this has happened to me 3 times already. This is very frustrating and scary.

The abs, ! brake and auto hold lights activated. I took in into the Hyundai joplin, mo dealership on may 2, 2024. They could not find any thrown codes and suggested it was most likely the "ieb module" which they replaced and after doing so, the warning lights remained activated. As of may 22, 2024, they are ordering a new ieb module to install (backordered into June). This seems oddly similar to previous abs and brake problems of earlier models and makes me feel uneasy with the safety of this vehicle should they ever get it remedied.

While driving 35mph on a 3-lane street in the far left lane, a driver of a Ford f-150 was in the center lane about two car lengths ahead, decided to make a right turn onto a residential street (as if he were driving a semi). As I got closer, the forward collision warning suddenly alerted and immediately initiated emergency braking system causing all 3 passengers to be thrown forward. I hit the steering wheel before seat belt caught me. I was not even within distance and he was turning in opposite direction of my lane. There also seems to be sensitivity issues with lane keeping feature as in phoenix, there are never ending freeway construction with make-shift lanes not always marked well. On several occasions the steering wheel was jerked out of my hands because it couldn’t detect the lanes any longer. It has caused me to avoid freeways all together and has made me miss the exit off the freeway twice now. I thought this feature only activated during active cruise control, but apparently it does it regardless. Now I’m beginning to have problems with display going out at the worst times. I will be taking my Tucson to a dealer to have them deactivate both systems & advise of display. I shouldn’t have to pay for this. I’ll take over the driving, thank you very much!.

The contact owns a 2022 Hyundai Tucson. The contact stated that while driving at 25 mph for unknown reasons, he lost consciousness and crashed into a swing, curb, vehicle, fence, and pole. The contact stated the automatic braking and collision mitigation braking system failed to engage. The contact was provided with medical attention. A police report was filed. There was no reported fire. The air bags were deployed. The vehicle was towed to a car wreck auction site. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted, who opened a case and informed  him the system was working as designed and only recognized people. The vehicle was not diagnosed or repaired. The failure mileage was approximately 10,000. The vehicle was deemed a total loss. The VIN was not available.

Emergency breaking went on without any traffic around while driving on freeway. The car put the breaks on and took control of the steering. Lasted about 10 to 15 seconds.

While driving over 50 mph the emergency brake has initiated 3 times in a 4 month period. There are no cars in front of my vehicle and it is not the collision warning but it will flash on the dash the the emergency brake is engaged in red, it will make a warning beeping noise and the car will brake on its own.

My vehicle has been malfunctioning with the automatic emergency brake. A total of 5 times. I am driving down the road going around 50-65 mph I am the only one in my vehicle and all of the sudden it puts the emergency brake on. It’s like someone else takes over my vehicle. Fortunately I have not been rear ended. Nobody has been in front of me when this happens the first time. It is not linked to or to be confused with the collision warning, it is wholly the emergency braking system that is put on with the light stating this & throws me forward into the steering wheel. I towed my vehicle into the bakersfield Hyundai shop & they have been unable to duplicate my problem with the vehicle. I have lost all confidence in my vehicle due to it has done it a total of 5 times and I just got it in September 2023. It has been in the shop for this month. Was taken to them by tow truck on 2/7/24. Was told by tow truck driver that I would be in body bag if it happened again especially in front of a diesel truck. This is either a first of a major recall or a lemon car. Either way not wanting to get in it again. Needs to be addressed and they can’t do anything about it. I do not have any pictures of my vehicle due to it is an internal issue but I do have the paperwork from the dealership shop.

The car suddenly and unintentionally accelerated. To avoid going through the back of my garage, I turned slightly and hit the frame of the garage. It continued to accelerate for a few seconds until I managed to stop it. I then backed up. Again, the car suddenly unintentionally accelerated. I managed to stop it. I slowly drove it into the garage. I left it in the garage until having it towed to planet Hyundai. I did not want to drive it in case it accelerated on the drive to planet Hyundai. I was driving about 5 mph when I hit the frame of the garage. The car continued to accelerate. Automatic emergency breaking and forward collision warning. The vehicle has been inspected by the manufacturer. The inspector or the dealer could not reproduce the problem. The vehicle can be inspected. The vehicle has been parked at planet Hyundai from 1/29/2024 to 4/15/2024 I reported the incident to Hyundai USA. I have not received any inspection reports.

I was driving on the freeway and suddenly the auto emergency breaking auto system activated. However there were no cars ahead of me, the road was completely clear. I was driving within the speed limit. Thankfully there were no cars behind me; otherwise this could've ended very badly. I pressed on the accelerator multiple times and the emergency breaking disengaged. Since I was driving I did not want to get distracted by figuring out how to disable auto assist. But the next time I got into my car I am went into the dashboard system to turn off auto emergency braking and set it only to provide warning notifications. It was not that easy to do. I had to google it and look at multiple user forums to figure out how to turn off auto emergency breaking in the dashboard.

I was driving home on christmas day 2023 in my 4 month old 2024 Hyundai Tucson hybrid. An hour into my 4 hour drive my car began making a low whump whump sound. No alerts or alarms came on my display to indicate anything was wrong. The noise was off and on for a couple miles. Suddenly my emergency brakes slammed on, my dash went red and the alarms went off. No one was in front of or around me. Had someone been behind me I would have been rear-ended. This was while I was going approximately 75-80. It could have caused a massive wreck had the freeway been congested. The noise went away after that and I made the rest of my trip without incident. The dealer said they couldn't replicate it and the analysis showed nothing was wrong so there is nothing they can do. I have found web forums and a reddit thread with numerous people complaining about the exact same issue with their newer Hyundais. So far a lemon lawyer seems to be the only recourse.

On multiple occasions, my new Hyundai Tucson randomly deployed emergency brakes while traveling on highway. This created a dangerous condition as my vehicle started braking without reason which prompted vehicle following my vehicle to slam on their brakes.

No known malfunction at this time on my vehicle - however a recall #251 has been issued with no repair available. Recall strongly recccommends parking car outside and away from structures due to possible fire which can also occur during driving. This problem has been going on with Hyundai cars for several years - and they still don't have a solution??? I called my two local dealerships and neither was aware of recall campaign 251. I asked if my abs module completely failed - what module would they replace it with? I was advised that they would probably sell me a new one costing $1900 plus labor that has the same problem!!! Hyundai is not taking this seriously - this is not being repaired in a timely manner. Please restrict them from selling anymore cars in the USA until this recall has a remedy!.

The contact owns a 2023 Hyundai Tucson. The contact stated while driving at 55 mph with the cruise control activated, the forward collision avoidance warning system activated, and the vehicle inadvertently applied the automatic braking before releasing. The contact stated no other vehicles or objects were nearby. The forward collision avoidance warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 2,000.

Sudden braking / collision warning. Approximately 10 times in reverse at a very low speed. 2 times in forward drive (once at a very low speed & once at approximately 30 mph). Dash constantly alternates between warnings for uneven roads ahead and slippery roads ahead. I took it to brookshire Hyundai service on 7/19/23. I was told that Hyundai is aware of the problem but doesn’t know how to fix it so just take my car home and check back to see if they have a fix in a month or so.
