2025 Hyundai Tucson Hybrid: screen or infotainment failure

Filed Nov 7, 2026 · Electrical · NY

I am reporting a major safety hazard on my 2025 Hyundai Tucson Hybrid Limited. The car has a bad wiring connection behind the dashboard that causes the screens to black out and critical safety systems to fail. I have taken it to the dealer 5 times, but they haven't fixed the hardware issue. Over the last week, the problem got much worse. On Monday, November 2, 2026, the main navigation screen went completely black while driving. Then, on Thursday, November 5, 2026, as soon as I started the car and before I even began driving, the computer network crashed. My dashboard immediately showed a "Check Driver Assistance" warning, and the ABS (Anti-lock Braking System) light, traction control light, and master warning triangle all turned on at the same time. All of my automatic safety brakes and cameras shut off completely right at startup. Driving a brand-new car where the speedometer goes black and the emergency brakes turn off is terrifying and life-threatening. The dealer is refusing to replace the bad wiring harness.

Display cluster recurring issue even after repair and software update. All warning lights on while at highway speed. Initial event in July 2025 - repair done. Coincidental with recall notice related to cluster display. Blank screen/cluster display while driving on July 30, 2026 - with eventual repair within same week. But, in October 2026 - all warning lights re-appeared intermittently from just flashing to steady display of at least 2 mins. Service date (third of same issue- excluding during regular maintenance where recall update done) already scheduled 10/26/26 at dealership.

Electronic display keeps rebooting while driving. Today dashboard info (speedometer, tach, gas level, etc.) totally blacked out for a 25 mile trip. Couldn't tell how the speed, how much gas left, etc. Vehicle has been serviced twice for this, most recently 6/30/2026. Software upgrade did not fix.

Vehicle: 2025 Hyundai Tucson Hybrid | Purchase Date: 10/2025 | Mileage: ~2,800 | FAILURES: On 5/11/2026, the AEB warning light (FCA system) activated without cause while parked. On 5/13/2026, the left side instrument cluster went completely dark and was unresponsive. Multiple reboots failed to restore it. Infotainment (right side) rebooted; instrument cluster did not. Vehicle brought to Hyundai of Las Vegas on 5/15/2026. RECALL CONNECTION: This is consistent with Recall 26V047000 (Hyundai #293), issued 1/26/2026, for 2025 Tucson instrument panel failure violating FMVSS No. 101. My VIN is not in the database. I request VIN inclusion review as my experience is identical. The OTA/dealer software update was never applied prior to this failure. SAFETY RISK: Loss of instrument cluster eliminated ability to monitor speed, fuel, and warnings while driving. Unprompted AEB activation raises concern about FCA reliability — risks unexpected braking to cause potential crash or failure to engage. Consistent with FCA recall issued 5/16/2026 for my vehicle. DEALER: Hyundai of Las Vegas confirmed and repaired under warranty, described to me only as a hard reset. Diagnostic was not indicated on my report. Service advised me that recurrence is likely. Note: FCA recall issued 5/16/2026 was not addressed during this visit. Second appointment required. the federal safety agency: 26V047000 | Hyundai Recall: #293 | Case: 42767545

The center infotainment display flickers then goes fully blank while driving, caused by a defective coaxial cable with undersized shield width (Hyundai TSB MC-11010978-0001). When the screen blanks, the backup camera also stops working, leaving no rear visibility when reversing. Audio and head-up display still function. The vehicle and component are available for inspection. Safety risk: the display and backup camera fail without warning during normal driving and while reversing, eliminating rear visibility and risking striking pedestrians, objects, or vehicles. Failures are triggered by heat, potholes, and braking—routine conditions—so the loss is unpredictable. The dealer reproduced and confirmed the problem, identified the TSB cable defect as root cause, and made multiple failed repairs: tightening clips, replacing the wiring harness, replacing the head unit, and performing the TSB repair. The identical symptom returned after the TSB fix. The vehicle has been inspected only by Hyundai's authorized dealer through these repeated visits—not by police, insurance, or a field engineer (field engineer involvement is being requested). No warning lamps or messages precede the failure. The first symptom is the screen flickering, immediately followed by the screen going blank and the backup camera failing. Symptoms first appeared at 10,717 miles on 07/23/25.

Navigation screen flickers and goes black and then reboots and comes back on while driving. Extremely distracting and dangerous. Dealer kept car for ten days and replaced the screen but problem persists. Happens almost every time I drive. Might be triggered by uneven road surface but difficult to tell. Much online chatter about the issue. Dealer acted like they’d never heard of it before.
