Our dashboard went blank and said “No Signal” over two weeks ago. (recall 304). We took it in for service. They did a Software upgrade which is the stated remedy. Two days ago it did it again. This time we had it towed to the dealership. They have had it since Thursday but no word back on a solution

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. This system glitch distracted me at a critical moment, causing an impact with a curb. Given that this incident was precipitated by a verified malfunction of a federally regulated safety system (FMVSS 111), I requested that Hyundai corporate review this case, investigate the failure of this component, and cover the cost of the $3,337 structural repairs. They have denied my request. I am aware that NHTSA Recall 26V400000/Hyundai Recall 304 is pending complete entry of all affected vehicles (vehicle was built at the Montgomery plant). Hyundai issued Technical Service Bulletin TSB 24-BE-001H for 2022–2026 Tucsons. It officially documents that these infotainment systems suffer from "freezing, lagging, unresponsive touchscreens, and intermittent blank screens". The bulletin attributes this to a loose internal coaxial cable and software bugs. I feel strongly that the camera freeze is a direct byproduct of this documented hardware/software defect. Hyundai explicitly stated to the federal government: "An instrument panel display that fails increases the risk of crash".

The instrument cluster intermittently goes completely black while driving, causing loss of the speedometer, warning lights, and gear indicator. The failure occurs randomly, including while the vehicle is in motion. The symptoms match the known 2026 Hyundai instrument‑cluster recall, but my VIN is not currently included.

I am writing to formally document a serious, recurring safety defect in ou 2026 Hyundai Tucson Hybrid, purchased less than a month ago. The vehicle has now exhibited multiple distinct dashboard warning faults related to the electronic shifter system, has left me stranded on more than one occasion, and has been sitting at Schomp Hyundai in [XXX] , for the second time, for over one week, with no resolution. The dealership has been unable — or unwilling — to properly diagnose the issue despite photographic documentation of the active fault warnings and the existence of Hyundai-issued Technical Service Bulletins directly addressing this problem. This letter serves as formal written notice pursuant to Colorado's Lemon Law (C.R.S. § 42-10-101 et seq. Since taking delivery, I have experienced multiple occurrences of two distinct dashboard fault warnings on this vehicle. Both have been photographically documented with date-stamped images: • "Shifter System Malfunction! Service Immediately" — The vehicle became inoperable and could not shift gears, leaving me stranded. "PARK Malfunction. Engage parking brake when parking vehicle." — A secondary fault indicating failure of the electronic park system, creating a serious safety hazard. These faults are not related to any collision or external damage. They are pre-existing manufacturing defects that began occurring in the first week of purchase. Notably, this is a known and documented issue affecting Hyundai Tucson Hybrid models. Hyundai has issued Technical Service Bulletins TSB #21-AT-007H and TSB #21-AT-009H. I drove the vehicle approximately 8 times (including to and from the repair center) and have had the issue multiple times.I am formally requesting the following immediate actions: • Direct the dealership to perform a complete GDS historical DTC scan per TSB #21-AT-007H and #21-AT-009H and provide full written results.

After 3 months and 840 miles, my 2026 Hyundai Tucson wouldn't respond one morning. No power at all, including to unlock the car. Road side assistance struggled to jump out but finally the car started, but the cluster panel would not turn on. I had to drive to the dealership with no speedometer or other screen sensors, as well as a lack of blinker or lights. This is outrageous because I barely drive the car and it's brand new.

Wife was driving car and the steering locked up and she could not turn it for about 5 seconds. second issue was put it in reverse and it would not come out of reverse, she had to turn car off and on 3 times to get it to put it in park or drive. I ran this through my Claude AI and it says this is an ongoing problem with the Hyundai Tucson. Please make them fix this before selling anymore vehicles as both are major safety hazards.
