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

Battery Management System failed Safety-Could not drive on interstate. Very unsafe. Dealer inspected problem afterwards. Warning lights appeared at time of problem. No warnings before. No signs of problem before it happened. SYNOPSIS: After driving through a torrential thunderstorm on the interstate (06-13-25) and as we were getting ready to slow down for our exit on the interstate, we hit the brakes and our SUV gave us a warning. The warning said, "Battery Management System Discharge". The SUV is a hybrid. At this point the SUV locked into E V mode. Our SUV would only go 10 mph which was very dangerous. It should be able to go up to 35 mph in E V mode and then past that, switch into gas mode. As stated, we could only go about 10 mph. We made it to our exit and found a spot to pull off the ramp. We let the SUV sit for a few moments and turned it off. We let it sit for a minute and then turned the car back on. The SUV when we turned it back on gave us a check engine light and still would not go over 10 mph. Luckily we were stopping for dinner. We were able to proceed to our destination. After dinner around an hour or so, when turned the vehicle back on, the SUV still gave us a check engine light. but was able to drive normally and switch between E V and gas modes. We made it home safely at the end of the weekend on 06-15-25. On 6-16-25 we took the SUV to be looked at by the dealer we purchased it from. Our phone app showed code DTC P0AA600. We gave the code to the staff. The staff inspected the SUV. The report stated, "customer states stopped driving and there code P0AA600 Battery Warning Light NPF Could not duplicate problem. Tech scanned for codes Code P0AA600 was found as a history code. Tech checked live data and everything came back within spec. Followed the flow chart procedure for the code.

The Driver Attention Warning is a dangerous feature that can't be turned off. It is constantly going off requiring that I take my eyes off the road to see why it chimed. I am a Disabled Veteran with an eye condition that requires me to wear very dark glasses in bright sunlight. The car is not drivable with my glasses on as the camera can't see my eyes. I was almost involved in a serious accident on I459. As I drove between an 18 wheeler and another SUV a red light on the dash and a message flashed that stated "Regain control of the car". The system slammed on the brakes which caused the car behind me to almost hit me at 70mph. This occurred in heavy traffic at approximately 8:30 AM. I almost lost control of my SUV.

I leased a brand new 2025 Hyundai Tucson on March 15, 2025, with fewer than 10 miles on the odometer. Shortly after driving an additional 10 miles, the vehicle-??s screen malfunctioned, displaying burn-in and becoming non-functional. This issue significantly affects safety, as it renders the backup camera unusable during operation. The vehicle was first brought in for service on March 17, 2025, but the issue was not resolved. Subsequent service attempts were made on March 20, April 9, and most recently on April 11, 2025. As of today, the problem remains unresolved. The vehicle has been in the service center for approximately 15 days since the date of purchase. In addition to the defective screen, the vehicle failed to start on one occasion, leaving me stranded alone in a parking lot, stuck in accessory mode with the brake locked. The car has also exhibited alignment issues, consistently pulling to the left while driving, which has required two alignments since the purchase date.

The Driver Attention Warning continues to go off shutting the cruise control off. This happens continuously and is a safety issue when driving in traffic and the vehicle suddenly decelerates. This causes traffic behind you to almost reared you because the vehicle decelerates so quickly. Hyundai suggests to move seat, not to wear glasses and other options that in themselves are additional safety concerns as seat positioning and glasses are needed for driving. So far my car has had the sensor located on top of the steering column shimmed up, and wiring harness replaced all to no satisfactory conclusion. Hyundai is aware of the issue, but has no solution to the issue. I-??ve been in a loaner for almost 2 months while they string me along looking for a solution. Something needs to be done to fix this safety concern.
