   In August/September 2025 my mother's Tucson would randomly shut down on her (completely stall while driving) and she would not be able to turn it back on. If she waited a little while, then she would be able to turn the car back on but it was unknown when the issue would happen again. We took it to the dealer several times after each shutdown and the dealer stated it was not throwing a code and they could not diagnose the problem. The last time we took it to the dealer, the…

   I have experienced 4 repeated issues within 4 months with my vehicle. Starting in September 2025 and the 4th and current issue today 1/12/26.

   Was told by dealership that forward camera assist is not functioning, but could not tell me why it failed all of a sudden. No accidents. $1586 to repair because no longer under warranty. Vehicle is only 5 years old.

   At times, this vehicle will refuse to go. You will get an alert in the dash that the emergency braking system has engaged. It may be a door is not completely shut, or sometimes it's just that I don't have my seat belt on. It seems to be inconsistent, because I often times put my seat belt on after I finish backing out, and am ready to go forward. If there is any kind of incident that requires a fast escape, this "feature" could cost somebody their life, or cause them to deal…

   I went to Thompson Automotive to finance a vehicle and within a month and half my engine blew. There were no engine lights, no lost of oil, no warning, no signs of any error, before this series of malfunctions took affect. I was on my way to the dealership and my car being slowing down to a complete stop as I was getting off the highway ramp. I was traveling at the speed of 25mph, when the car started to make loud noises that I never heard before that day, and completely…

   Both waning lights came on for lane assist and forward collision warning. I took the vehicle to the dealership. They said the camera was not working and I would have to pay $1700.00 to install a new one. It appears there are 2 separate cameras involved. I was asked if I struck anything. I did not and the camera in the grill is I damaged as is the forward collision camera in the rear view mirror. The paperwork I received from the dealer says “software error” I have not had…

    It happened on two different occasions but only when driving at high speed using the Cruise Control. Here is what happened. Driving on the Cruise Control I “Set” it to 70 mph. Driving on the two lane highway with both lanes blocked by other vehicles, I pressed the “brake” pedal. The car slowed down and I continued driving at a lower speed. When traffic in front of me cleared, I pressed the “Resume” button on Cruise Control. With no obstacles in front of me, my car was…

    For at least the last 60 days, the blind spot warning camera system will disengage while driving. Took the vehicle to the local dealer, who had the car for 2 days and could not determine the cause. They did discover it will disengage after driving the car for 18 miles. They have called Hyundai for assistance. So far, no information received back from Hyundai on how to correct this issue.

    The backup camera in the 2020 Tucson Ultimate is blurry, creating a serious safety issue. We have taken the vehicle to the dealer repeatedly with this complaint and although the service advisor agrees, Hyundai has refused to replace or repair the camera. Note that there are many of the same complaint that can be found through a simple internet search, but apparently Hyundai refuses to acknowledge and repair the issue. Both the driver's safety and the safety of others are at…
