2025 Hyundai Tucson electrical problems

Filed Nov 3, 2026 · Brakes, Electrical · NJ · crash

We were driving 10-15 mph on a local road approaching a red light. The brakes stopped working so we couldn't stop at the red. When we pressed the brakes more, we had unintended acceleration and had to go on the sidewalk to avoid cars. Then had to swerve and zigzag to avoid cars coming out of an intersection and oncoming traffic. We were going around 60 mph while pressing the brake. It was horribly dangerous for us and others. We hit signs and poles for avoid cars and sustained significant damage to the car. The manufacturer states the recorder does not show anything prior to the sudden acceleration. It only confirms that the brake was being used and not the gas, as we had already known. Contrary to what they report, the emergency braking system is not what helped us as it did not work as intended. Driver ended up putting the car in neutral when we got away from traffic, and that is how we were finally able to stop. Since we don't have a dependable assessment from the investigation, we are guessing this was a computer/electrical malfunction.

While driving, the digital instrument cluster on my 2025 Tucson Hybrid Limited goes completely black and displays only "NO SIGNAL" in red, along with multiple warning lamps (AFS, ABS, EPB, airbag/brake indicators). The speedometer, fuel gauge, gear position and all driver information disappear while the vehicle is moving. This happened multiple times - recent was on Thu, Oct 29, 2026.

I was driving home tonight and while driving the car lost all power on the full screen and headlights. This is the second report of the same problem. It was like a blackout at two o clock in the morning. I couldn’t see the speed and the lights went out. It did come back on in immediately.

On July 17, I took my vehicle to Hyundai of Venice due to a safety recall of the automated emergency brake, the dealership told me that they had fixed the recall. On October 10 when I returned for service, I again notified them that the safety features such as the automated emergency brake and the Forward collision warning were not working. They ignored me again. Then on October 21, 2026, I was driving my mother to run an errand before her doctors appointment as I was pulling into a parking spot going no more than 3 mph. The safety features were still not working and I scratched the vehicle on the left of me which was empty. I then stopped the car, got out and took pictures of the license plate and of the scratch, and then looked at my front bumper and saw that I was also scratched, my mother, and I went into the supermarket to speak to the manager and attempt to call for the police, but then my mother noticed their brake lights were on and people were in the car so we hurried out to notify them that we had scratched their car by accident, I gave my insurance information and my mother gave her telephone number and after her doctors appointment, I contacted my insurance company to notify them of the issue. My concern is that I notified Hyundai of Venice twice about this issue, but due to my autism, I feel that they ignored me, and this small accident could have been avoided if they had checked that my safety features on this new vehicle were all fully functional.

When shifting into reserve, a green screen appears. I have to put my car back in to park and then reverse to get my back up camera to start working again. It doesn’t happen all the time but since my last software update, it has been happening more frequently.

Shifter malfunction, service immediately warning comes on. The car will not shift out of park and cannot be driven. It has happened 4 times now. No one has been hurt, but I have been stranded multiple times. The dealer couldn’t reproduce the issue the first time I brought it in, but they did second time I brought it in for the same issue. They replaced a part that was supposedly faulty, but the issue persists after the replacement.

Two instances of the center screen malfunctioning. One was an intermittent blip of the screen turning black and then turning back on while driving. Additionally, during this same instance of the intermittent blip of the screen turning off for about 3 seconds, my headlights which are set to auto also turned off while I was driving at night and then blipped back on when the screen came back at the same time. Second instance, the center screen was black and never came on when the car was initially turned on and the screen remained black for the entirety of my drive until the car was fully turned off and then back on. Yes, this is available for inspection upon request. Safety was put at risk by losing headlight visibility at night highly increasing the chances of an accident as well as losing important carplay navigational directions on center screen. Problem has been reproduced as these issues both occurred within one week (the week of August 16-23, 2026). The vehicle has not been inspected. During the time of both events there were no warning lamps or messages that appeared.

The instrument cluster malfunctioned suddenly leaving the control panel completely black (no odometer, speedometer, speed range, turn signal indicators, etc.). The driver was therefore unable to know what speed they were driving, how much fuel remained, and lacked any sort of signal that turn signals/blinkers were on or off. It was unsafe to drive and impossible to accurately comply with legal speed limits. Local Hyundai dealership inspected the car and confirmed that the cluster had to be replaced, which they did (required 11 total days of being unable to use the car).
