Warnings problems of the 2020 Hyundai Tucson

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. Driving when all of a sudden all of my brake components lamps come on dash oard, forward collision alert, and check engine, my vehicle struggles to accelerate accurately. Blue link diagnostic throws various codes such as ecm, transmission control system, even "multiple possible issues". Each time my vehicle has been at Hyundai dealership for repair. Each time they repair something different 1st- replace abs module and hydraulic brake, 2nd - happened out of state at my mother funeral and replaced my ecm, 3rd couldn't figure it out and guessed it was my forward collision camera and replaced it, 4th - is today and awaiting dealership diagnosis. This issue has left me stranded several times local and long distance, occured in middle of driving including on highway, and overall uncertain of the safety and reliability of the vehicle as each time it has been the same type of issue. I have been in communication with Hyundai corporate since October and they stated that even tho I only have 24k miles on the vehicle that it is outside the state of in lemon laws for a buyback. If I hadn't purchased an extended warranty I would be in even more debt or unable to put it in the shop even tho I don't feel like this should be my burden when I have kept this vehicle in great shape, low mileage, frequent oil changes, etc . However the safety of my vehicles goes unresolved. At this point I am uncertain that Hyundai is properly diagnosing my vehicle and not certain how these issues are impacting other components of my vehicle such as brakes, transmission, engine, sensors. I am the only owner of this vehicle bought brand new. I have checked repeatedly for any recalls that I have not addressed and at this time none are pending. I fear that this vehicle will continue to have more safety issues.

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.

While driving the vehicle suddenly started alarming indicating to check "forward collision warning" followed by an alert to check "lane keeping assistant. " immediately pulled off the road shut the vehicle off and checked the perimeter. No issues noted. Issue continues, while waiting for service from local dealers.

Warning lights for lane keeping, blind spot, abs, autohold, foward collision systems came on and will not reset. Reports of this all over Hyundai forums and owner fan pages (facebook, etc). It can fool the driver into believing the car is about to be in an accident prompting panic response in drivers.

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 the work done due to the cost. I was also told by the dealer that they are aware of other customers with the same problem.

Hyundai Tucson sport 2020, this happens always, while driving in the highway, long distance the forward collision warning activates (no cars in front of me or any objects) and the SUV make a sudden stop and it sound a loud scary noise, then I have to park, turn it off and then start the SUV again because the rpm starts going up. This is a safety hazard, luckily no one was behind me or I could get hit in the middle of the highway. I took the SUV to the Hyundai dealership where I bought it in san juan, kennedy, but they said they didn’t find anything. I took it then to the Hyundai dealership in caguas, p. R. To have it check and still waiting on a response. It’s been a year and still no one finds what’s the problem. I feel my life is at risk when driving in the highway.
