My 2025 Tucson hybrid violently stopped in mid traffic while leaving the intersection once the signal turned green to proceed. I accelerated getting to speed limit then it abruptly stopped, violently throwing contents from back seat to the forward cabin. Both, myself the driver and my passenger were jolted violently. The school bus behind me had to stop quickly as we were just getting up to speed from a stop light. The vehicle is brand new, 2024 miles on it. Tucson Nline Hybrid with all the safety features turned on. I called the dealer and service rep which both instructed to turn off the FCS Forward Collision System setting. I did but this shouldn't be happening and will cause bodily harm/damage, and possible death is a specific situation. This abrupt stop was jarring to both people in the car.

1 forward collision unexpectedly slammed on the brakes when I was trying to go forward to make a left turn. There was no one in front of me nor each side of me. I had 2x4’s in my car that were thrusted forward damaging my dashboard and display. I was told to take it to the dealership on Monday 2 I was fine just hooked up, but the driver was pissed off at me thinking I was stopping short on him 3 randomly the rear sensor would go off telling me they are too close when I’m at a complete stop. It has randomly stopped short on me but I thought it might have just been an over sensitive sensor. I have previously owned an Ioniq 5 and the sensor would never stop going off even if I was 2 car lengths away. 4 the car is going back to the dealership on Monday so it has not been expected yet 5 exactly 6 days after purchasing the car the airbag indicator showed up on my dashboard while I was driving. I was used to the Ioniq 5 sensors always going on when I was stopped waiting for a green light that I just thought it was the same way. It had abruptly stopped on me three other times between the 6th and today the 21st. I have only had it for 3 weeks. I have never gotten any warnings before the car just slams the breaks on. After looking online about this issue I decided to make a report before I take it to the dealership so you have it on file. I am very disappointed with this vehicle and was so excited when I bought it. I have been a loyal customer of Hyundai since 2017 when I bought my first Ioniq and I have purchased 6 other cars for my family members since then. I still purchased the Tucson after having to take a 15,000 loss because the Ioniq 5 never held its value. Now I’m wondering if I should switch manufacturers

On 2 separate occasions, the forward collision warning system activated. On both occasions I was under control of the vehicle with my foot on the brake approaching a vehicle that had slowed while entering into a round about...I was approximately 10 feet from the car in front going about 6 mph. All of a sudden several warning indicators activated (audible and visual) and then out of nowhere, all four wheels locked and my car came to a skidding/juddering stop. I immediately looked in rear view mirror fearing I was going to get rear-ended. The vehicle in front proceeded to move on and I tried to get myself together and get moving. I was shocked that this had happened as it was totally unnecessary. I was completely in control of the vehicle prior to the activation.

The 2025 Hyundai Tucson's Adaptive Cruise Control (ACC) system does not operate properly due to either a design flaw or a flawed implementation of the design. Hyundai's integration of Forward Attention Warning (FAW) with the ACC prohibits the driver from using ACC while wearing sunglasses. If one is driving the vehicle with ACC engaged and puts on sunglasses, the FAW flashes a warning on the dashboard and disengages the ACC. In order to engage cruise control the driver must interact with the onboard video display system to switch from ACC to "dumb cruise". Obviously the driver's attention is distracted while manipulating the selection of cruise control. The driver is also forced to compromise driving safety because they are forced to choose between wearing sunglasses and being able to use ACC. Use of ACC enhances safety especially when driving into the sun or in low visibility situations. The incompatibility of ACC with sunglasses wear then compromises safety. To make matters worse the FAW options screen provides erroneous information. It indicates that the driver can turn off FAW, but turning it off does not in fact turn it off. Turning it off stops the FAW warnings only until the driver turns on and engages ACC at which time ACC apparently forces FAW back on and active. I took the problem to my local Hyundai dealer who confirmed the problem and indicated they could not repair the problem. Since I am considering a Georgia Lemon Law claim, I asked whether I needed to bring the car back since the lemon law gives the dealer/manufacturer 3 tries to fix the problem. The dealer indicated that would be a waste of time because Hyundai will not support/allow the issue to be corrected. The dealer indicated this is a known issue. An Internet search also confirms that Hyundai's FAW + ACC integration is flawed. Additionally it is not clear whether other enhanced vehicle safety systems such as automatic emergency braking are compromised by the wearing of sunglasses?
