2024 HYUNDAI TUCSON HYBRID Forward Collision Avoidance Problems

Issue has happened twice now, about 2 months apart. Driving at highway speeds, 60-75 mph, no other cars around, no reason for braking or stopping, the emergency brake comes up for a few seconds, abruptly slowing the car down for no reason. Very scary as the car starts to slow down from a high speed, very jolting. I've complained to Hyundai but they claim they are not aware of the issue and there are no codes the vehicle puts out so they cant investigate further without replicating the issue, but its random and you don't know when its happening. I've looked online and it appears there are quite a bit of 2023/2024 Tucson's that are having the exact same issue I am.

From the first day of purchase last June 2024, the front collision warning and avoidance system does not perform as advertised. If a vehicle cuts you off or you approach a vehicle too quickly the warning and braking do not intercede. I’ve taken the car to our local deal 3 times and they have found no trouble codes and say there is nothing they can do. I was also told by the service department manager “that they are all like that”. As a reference, we owned a 2019 Kia Sorrento for 140,000 miles and that collision avoidance system worked perfectly. I also contacted Hyundia National Service and they simply sent me back to the dealer. Lastly, I submitted a Lemon Law request that was rejected by Hyundia.

it happened again. While traveling at highway speeds behind a slow poke, 2 cars passed me on either side at nearly the same time. this caused the auto braking system to activate, abruptly slowing my car for now reason. Luckily no one was tailgating me at the time. This is the 4th time the car has braked for no good reason on the highway (see previous reports) and the 2nd time when 2 cars passed on either side at the same time. This is clearly a software bug that needs to be fixed!

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.

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.

On a recent road trip to Utah on 2 occasions the cars automatic breaking system assumed a vehicle in the left lane and ahead of me by a few car lengths, had crossed its lane causing my car to brake abruptly at highway speed. The first time this occurred I was so surprised I don't remember what the other car was doing. However, the 2nd time I do remember the circumstances. I was driving east out of Amarillo and noticed a double semi trailer weaving a bit in the right lane. I was one lane to the left. There was a strong South wind and it appeared the truck was having trouble staying in his lane. My lane was clear of traffic for at least 1/2 mile. The highway was was straight. The truck was 100 yards or so in front of me when my car suddenly braked very hard I'm guessing reducing my speed by 20 or more mph. I'm glad there was no one on my tail! There was no danger at anytime and there was no need for such hard braking. A week later, a third incident of the same typed occurred. I was driving on [XXX] heading north in moderate traffic at highway speed and the car again broke heavily when there was no danger. Again, a black BMW was to the right of me- this time only 3-4 car lengths ahead. I was watching the that car as I would be overtaking it soon, when it moved close to the dashed lane marking but I don't believe it crossed it, causing my car to brake hard again! Again, I was lucky there was no one behind me, but this could have caused an accident! Again, there was no danger-- at least until the car hit the brakes too hard. The car collected a lot of bugs on the road trip and I had not washed the car prior to the 3rd incident. The car has been washed and something similar has not occurred again- but I have not needed to drive it on a highway since. Part 2 of this problem is the car's spyware called bluelink collects data on driving habits and reports / sells that info to others. In none of these 3 situations did I do anything to cause the car to beh INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMAT

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.

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.

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.
