2022 Hyundai Tucson

My wife was driving my SUV while I was a passenger. We were in the left lane, and put the left turn signal on while traveling south bound approaching an intersection to take a left turn (traveling approximately 3-5 Miles Per Hour and slowing) at the traffic light (traffic light was green). There was a car in front of us that had stopped waiting for oncoming traffic to clear and make the same left turn onto the same road as us. While traveling in this lane we hit a deep pot hole (not very visible while driving), just as we were approaching the vehicle stopped in front of us. When hitting the pot hole, our SUV seemed to leap forward a bit and when the brakes were applied to slow and stop, the braking system failed (appeared to freeze) and the brakes did not work, and because the braking didn’t work, our vehicle hit the car in front of us. Prior to and after hitting the pothole, no audible warning sounds or visible alerts appeared and no emergency braking was activated. The airbags in our vehicle never deployed. Our safety (my wife and I) as well as the safety of the 2 passengers in the other vehicle were at risk as we all could have been injured in the accident. As we needed the vehicle for transportation, we immediately began filing all the necessary police and insurance reports and brought our vehicle into an Auto Body Repair Shop to be repaired the next day. During the repair work, some of the responsible components may or may not have been replaced and the Auto Body Repair Shop also had all the car sensors recalibrated by a 3rd party, which is why we did not bring the car to a dealership to evaluate. To the best of our knowledge, the manufacturer, the police and the insurance company did not inspect the vehicle. We are not experts, but hitting a pothole might be considered an edge case, so I’m not sure that a dealership would have tried or been able to replicate the issue.

Unintentional and unexpected activation of emergency collision or adaptive cruise control, causing the vehicle to stop and become immobile in the lane of traffic. I was driving down the interstate with the adaptive cruse control on and the lane keeping assistance on. These both were on for about 20 minutes as I was driving down the highway. There were no vehicles in front of or behind me for a quarter mile or so. I as all alone with nothing around me. All of a sudden it seemed like the collision avoidance system activated. The car came to a complete stop in the right lane of the highway. I tried to proceed and could see the emergency brake was on, the engine was running the car was in drive but it would not move. Flipped on the hazard flashers and traffic caught up to me while sitting in the right lane of the highway waiting to get rear ended. Vehicles were barely getting by at 70 MPH. The car would I pressed the accelerator and the car move d forward enough to get off the highway, this took a minute or two. Once off he highway, I could see the emergency brake would not release. I turned the engine off went out to inspect all the forward sensors. There was no visible issue. I restarted the car after a minute or so and it proceeded normally. That was Saturday, this is Sunday, I am taking the vehicle to Hundai tomorrow for inspection.

On July 24, 2026, while driving on a marked city street with no vehicle, pedestrian, or obstruction ahead, the Forward Collision-Avoidance system on our 2022 Hyundai Tucson Limited AWD applied emergency braking on its own, three to four separate times, each lasting one to two seconds. Traffic behind us nearly struck our vehicle. My family was in the car. This is the latest event in a progressive electrical fault history. In June 2025, under warranty at 48,037 miles, a Hyundai dealer documented recurring multi-system warning cascades (forward safety, lane keeping, high beam assist, speed limit warning) and a failed auto start/stop system. The dealer's listed resolution was "battery voltage / replace battery"; their invoice records that no repair was performed. We replaced the battery at our own expense. The faults continued. In June 2026, the start/stop system shut the engine off at a red light and the vehicle would not restart, leaving us disabled in a live traffic lane. Power was only restored by cycling the hood release. Since then, TCM and ECU software updates and a battery harness replacement (our expense, approx. $1,200) have been performed. The faults persisted after these repairs and have now escalated to uncommanded emergency braking. Date- and time-stamped video and photographs exist for multiple events. Two Hyundai dealerships have not identified a root cause. Similar phantom braking reports exist from other owners of this model year. We no longer consider the vehicle safe to drive.

My 2022 Hyundai Tuscon came to a complete stop on the highway in Colorado twice in the last 2 months for no apparent reason. There weren't any obstacles or cars in front of me that would have caused the car to brake suddenly. I had passengers in the car and we were jolted forward. The air bags did not inflate and we were not hit from behind, but we could have been severely injured or killed. There are numerous "phantom braking" reports like this here on the NHTSA site for the 2022 model as well as more recent models. Yet Hyundai has only issued recalls for the 2025 and 2026 models. How are you addressing this issue?

I have experienced the Emergency Braking System Warning and Sudden Application of my Brakes when traveling at highway speeds for what seems to be no apparent reason. I thought it had to be a glitch related to just my car; However, this has happened twice in the past month and it is an unnerving experience. As I just read about this same problem occurring in later models of my car I want to document that this same problem exists in my 2022 Hyundai Tucson.

About once a month on average my Tucson's emergency system braking comes on without an emergency. It seems to occur mostly when taking an exit on the highway, but a few times it has been completely random. All of these instances have had no other vehicles around or any roadway barriers present. When it activated, lighting comes up on my dash telling me the emergency braking is activating. Sometimes it brakes, other times it does not seem to. Mostly, it seems that if I keep pressing down on the gas pedal it just turns itself off. I've never had my car come to a complete start but I have had it hit the brakes hard a few times. I bought the vehicle brand new and have had it for 4.5 years, and it has always done this. I've had the dealership reinstall the software that controls the braking system, but it had no affect. I ask the dealer every time I go in if others are complaining about this and I am always told no. However, I saw a similar recall was just put into place for the newer years of the Tucson, and it makes me think they are told to tell people no one is complaining about this.
