What owners report

Odometer Fraud. The contact purchased a 2026 Hyundai Tucson. The contact stated that they discovered that there was a mileage discrepancy after the purchase. The vehicle was a dealer sale. At the time of purchase, the vehicle mileage was 18. It was later discovered upon checking the Title that the mileage was 2,664.

Federal Motor Vehicle Safety Standard (FMVSS) 111 regulates rear visibility systems. It requires backup cameras to shut off within a specific time or distance after moving forward to prevent driver distraction. A screen stuck on the reverse camera means the vehicle failed to comply with federal safety safety standards in that moment, actively flashing an illegal, high-contrast visual distraction while trying to navigate. I am writing to formally report a critical safety defect regarding the infotainment system in my 2026 Hyundai Tucson, which directly resulted in property damage on 7/6/26. While driving at approximately 35 mph, the center display screen failed to disengage the rear view camera. The persistent, high-visibility flashing of moving traffic behind me in my peripheral vision completely obscured my forward safety alerts and navigation, creating an immediate visual hazard. …

The contact owns a 2025 Hyundai Tucson. The contact stated that while in reverse, several warning lights illuminated on the instrument panel, and the vehicle suddenly reversed without depressing the accelerator pedal and crashed into a light post. The air bags did not deploy. There were no injuries sustained. The contact sought medical attention after being overwhelmed by the experience. A Police report was not filed. The contact was able to drive the vehicle, and the vehicle was taken to the dealer, and the front-view camera was updated; however, the dealer was unable to determine the cause of the failure. The vehicle was taken to Imperial Body Shop to repair the body damage. After the software update was performed, the contact became aware that the vehicle failed to turn off immediately, and several attempts were needed to turn off the vehicle. …

The contact owns a 2025 Hyundai Tucson. The contact stated while driving approximately 35 MPH, the instrument cluster went black; however, the radio was still playing. There were no warning lights illuminated. The contact stated that the failure was intermittent and occurred while driving at various speeds. The contact stated that occasionally the failure lasted for 20 minutes before the instrument cluster returned to normal function. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the coaxial cable needed to be adjusted. The vehicle was repaired; however, the failure reoccurred. The contact had taken the vehicle back to the same dealer who diagnosed the vehicle and informed the contact that the instrument cluster wiring harness needed to be replaced. The vehicle was not yet repaired. The manufacturer was informed of the failure. …

My wife was slowly pulling into a parking spot, when at about 10ft from curb the car suddenly accelerated faster than she even thought the car even was capable of (the AWD likely helped). It hopped the curb and hit a tree. She backed it up to the parking spot (it acted normally) and had it towed to dealer. In hindsight, the car had been having a progressive amount and frequency of delay in normal acceleration, sometimes having a pause of up to second or two from pedal input to car response. We asked the dealer to check the EDR (event data recorder). The tech first said he didn't even know what that was, then that he checked with all his fellow techs and they didn't know either, then the story changed to the model not having an EDR. We politely told him which page in the Hyundai manual he can find it, and he refused to look, as did his boss. …

The contact owns a 2024 Hyundai Tucson. The contact stated while driving approximately 60 MPH, the vehicle stalled. The contact stated that before the vehicle stalled, there were several unknown warning lights illuminated before the instrument cluster went black. The contact pulled over and shifted to park(P) and was able to restart the vehicle after several attempts. The contact stated that the failure had occurred intermittently and at various speeds. The vehicle also occurred while stopped at a traffic signal. The contact had taken the vehicle to a local dealer who was unable to duplicate the failure. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 18,000.

The contact owns a 2023 Hyundai Tucson. The contact stated while driving approximately 45 MPH, the accelerator pedal was depressed while merging onto a highway, but the vehicle lost forward momentum. The contact stated that the message "Limited to 20 MPH" was displayed on the instrument cluster. The contact depressed the accelerator pedal, and the vehicle failed to respond as needed. The contact stated that the engine was not revving. The contact pulled off the highway and into a parking lot. The contact turned the vehicle off and on, and normal driving was resumed. The contact stated that the failure was intermittent and was occurring while accelerating. Additionally, the contact stated that upon starting the vehicle in the morning, the vehicle would jump forward while still in park (P). …

The contact's son owns a 2023 Hyundai Tucson. The contact stated that while driving at various speeds, various warning lights illuminated, and various messages were displayed on the instrument panel; however, the warning lights disappeared upon restarting the engine. The contact stated that her son was forced to restart the vehicle after the vehicle failed to accelerate from a complete stop on one occasion. The vehicle was taken to the dealer for diagnosis; however, the dealer was unable to diagnose or duplicate the failure. The contact was informed that the vehicle could not be diagnosed unless the warning lights were illuminated. The manufacturer was notified of the failure, and a case was filed.
