2025 Hyundai Tucson Hybrid problems

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.

On approximately three to four occasions, my 2025 Hyundai Tucson Hybrid has suddenly jerked or decelerated while driving, creating the sensation that the brakes were being applied unexpectedly. During there episodes, the vehicle did not respond normally to acceleration until the apparent braking released. A particularly dangerous incident occurred on XXX, when I was entering traffic after leaving a Subaru dealership in [XXX]. The vehicle unexpectedly jerked and failed to accelerate normally while applying the gas pedal. Another driver had to brake to avoid a collision with my vehicle. Hyundai Recall 302 addressing potential unexpected activation of the forward collision avoidance braking system, had already been completed on my vehicle on June 30, 2026. I reported these recurring incidents to the Zimbrick Hyundai service manager on XXX. The braking concern has not been diagnosed or repaired. I do not know whether these incidents are related to Recall 302 or another malfunction. However, I am concerned about unexpected braking or deceleration occurring in traffic and the risk of a serious collision. Attached are documentation confirming completion of Recall 302 on June 30, 2026 and email correspondence with Zimbrick Hyundai service manager documenting my report of the recurring braking incidents dated XXX.

While driving my 2025 Hyundai Tucson Hybrid on [XXX] toward [XXX] at approximately 70 mph on XXX, multiple safety system lights illuminated on the dashboard, and my turn signals stopped functioning. The dashboard turn signal indicators and audible clicking were not working. After shutting off and restarting the vehicle, the malfunction resolved. I brought the vehicle to Zimbrick Hyundai East [XXX] on XXX, for evaluation. The dealership identified eight historical diagnostic trouble codes across six vehicle systems, including multiple electronic communication errors, but no active codes. Following a 16 mile test drive, the technician was unable to reproduce the malfunction or identify its cause. No corrective repairs were performed. The vehicle has approximately 15,600 miles at the time of inspection. I am concerned this intermittent malfunction could recur while driving, preventing me from safely signaling turns or lane changes. The cause remains unidentified and unresolved. The attached photograph, taken XXX at approximately 8:42AM, shows one of several warning messages I reviewed during the incident. Multiple other safety system warning in indicators remained illuminated. I stopped reviewing them because doing so while driving was unsafe.

On Thursday night, XXX, my [XXX] son was operating the vehicle under normal highway driving conditions in [XXX]. He was driving in the left-hand passing lane with adaptive cruise control (ACC) and lane following assist (LFA) system activated. Without warning or driver input, the vehicle's adaptive ACC with LFA system malfunctioned, the car drifted to the left, overriding driver control. This unexpected system intervention caused the car to veer entirely off the left side of the highway into the grass and woods, where it struck trees and flipped over. The crash was severe enough to trigger full airbag deployment. The vehicle's integrated BlueLink system automatically activated upon impact, initiating an emergency call to dispatch an ambulance and local police to the scene. My son survived without any major physical injuries, but the vehicle is heavily destroyed. The XXX State Police - Stroudsburg has documented this under case number XXX. I have followed all servicing guidelines on this one year old car and downloaded all software updates as received. I see that this model year has a history of automated system faults, and this left hand malfunction directly caused a severe rollover accident. I have asked Hyundai to download the Event Data Recorder (EDR) data and preserve it before the vehicle is altered or dismantled. I have also informed my Geico insurance appraiser to preserve the data and coordinate with Hyundai. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While trying to start my 2025 Hyundai Tucson SEL hybrid that was parked on incline with 13,000 miles on the vehicle, the gear shift was stuck on Neutral and we could not even turn-off the engine. The failure occurred onXXX while parked at XXX Market ([XXX]. The vehicle was stuck on "Neutral" and the gear could not be changed nor could we even turn off the engine. Furthermore, because the car was parked on an incline, we had to apply break until car simply allowed us to have control over the gear shift function after about 30 minutes. As a result, we were highly distressed and could not even go out of the car in fear of car rolling back and crashing into another car or people. Fortunately, there was no crash, no injuries. The vehicle was taken to dealership but no diagnosis or repair performed since they required leaving the car at dealership for extended time and the dealership did not have the loaner car, which was included in the purchase warrantee. I believe this condition creates a safety hazard because the same scenario of being parked on incline on Neutral could happen anytime. The problem has not occurred again but we are extremely concerned for our safety. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

What component or system failed or malfunctioned, and is it available for inspection upon request? The rear middle seat's seatbelt anchors on the outside of the rear passenger seat's inner rigid LATCH system. It is permanently anchored under the seat, so it cannot be moved. This causes the middle seatbelt to overlap over the rear passenger seat's rigid LATCH system after installing a car seat, which is a safety concern, as the middle seatbelt would be rubbing against it. How was your safety or the safety of others put at risk? We cannot put an infant carseat in the rear passenger seat using the rigid LATCH system until this is resolved. Has the problem been reproduced or confirmed by a dealer or independent service center? UNKNOWN Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? UNKNOWN Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? No.
