There are 2 owner-reported electrical system complaints for the 2026 Hyundai Tucsonin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
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.
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.
