2022 Hyundai Tucson

I was driving down the highway going about 60-65mph with cruise control and LKA on. I turned my blinker on to switch lanes, checked my blind spot, and moved over to the left. As I was doing so, a semi switched lanes from the left into the right (my new lane) right in front of me. The truck then slowed down a lot, and usually my Forward Collision Warning would say something if my Adaptive Cruise Control isn’t on (or is and I’m just going too fast to slow down) neither of those things happened. No warning. No automatic brakes. No slowing down. I tried to engage the brakes manually but nothing happened. I slammed into a semi at around 60mph because of 3 different system failures. Not only did I hit the semi at 60~mph, apparently my brakes didn’t work at all and I spun out until I hit the concrete barrier on the highway. If my brakes had engaged automatically, I could have slowed down enough to avoid the collision altogether. And if they had engaged manually I could have at least minimized the damage to my vehicle (and myself) because I wouldn’t have hit the concrete barrier as well.

Vehicle randomly activated automatic emergency braking and the forward collision warning with no other vehicles in sight. The vehicle slammed on the brakes almost causing a trailing car to rear end our vehicle. This has happened 5 times with speeds between 40 and 80 mph over the past 4 weeks. Conditions were cloudy. Problem has not been reproduced by the dealorship. No inspections have occurred.

The computer(s) responsible for many of the safety systems have faulty software. The computer vision system incorrectly assess condition of the roadway and issues warnings that obscure the instrument cluster. The computer vision system also incorrectly determines that a collision is imminent (despite no obstacles being present) and activates the braking system. Hyundai has been aware of this issue since 2022 and has previously released a software patch to correct it. However, unpatched vehicles are still being sold (and resold) by Hyundai dealerships without being fixed because Hyundai has chosen to rescind the availability of the update. Unpatched vehicles are on the road preventing drivers from properly monitoring vehicle operation as a result of the continuous warning obscuring the cluster and are jeopardizing the occupants and other road users when the vehicles spontaneously initiate panic stops for phantom obstacles. Hyundai refuses requests to provide the existing update files because a future update with an uncertain release date is planned; release of the "upcoming" update has seemingly already been delayed 8 months.

During a recent accident, the driver pressed the brakes but they did not respond, almost as if they locked up. Police at the scene noted there were no skid marks on the road, suggesting the brakes never engaged. The vehicle suffered major side impact damage, including broken windows and crushed passenger-side doors, but none of the airbags deployed. This raises serious concerns about a possible brake system failure and airbag non-deployment defect. The vehicle has not yet been repaired and is available for inspection. Police have reviewed the accident, and the insurance company has also seen the vehicle, but no mechanical inspection has been completed by the manufacturer. There were no warning lights or error messages prior to the failure. The safety of the driver and passengers was put at risk because the car could not be stopped and the airbags did not deploy to provide protection.

What component or system failed or malfunctioned, and is it available for inspection upon request? > While driving, the following systems fail and become inoperable sporadically: blind-spot safety system, tire pressure monitoring system, smart cruise control system, lane following assist system, speed limit warning system, shifter system malfunction, infotainment system, HVAC controls and turn signals. How was your safety or the safety of others put at risk? > I lose access to all safety systems and am unable to see anything on my dashboard while every single light flashes on the dash. Being unable to utilize my turn signals is dangerous because I must restart the vehicle for the issue to be resolved. Has the problem been reproduced or confirmed by a dealer or independent service center? > The problems were confirmed - but NOT reproduced by the Hyundai certified service center. They stated that they can see logs of the issues and were unable to diagnose the specific failures without the warning lights being actively present. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? > Yes. It was sold to me as a Certified Pre-Owned vehicle directly from a Hyundai dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? > The warnings and failures appeared at 64,752 miles, which is less than 5,000 miles after the warranty coverage ended. I purchased the vehicle with 64,300 miles. The issues began less than 500 miles after purchase.

While driving 70mph on the freeway, the car’s emergency braking assistance activated twice for no apparent reason. This is very dangerous at such high speeds and could result in a serious accident if cars are following close behind. This car has not been inspected for this issue. A google search of this issue revealed many similar complaints that have not been addressed or taken seriously. A possible related warning message about “blocked forward safety” has appeared a few times in the last week.

While driving approximately 75 mph in the passing lane on highway, the vehicle suddenly automatically brake. Pulled back into the right lane and didn't really understand what happened. Next time i pulled out to pass and had a car on my right hand side it did the same thing. Pulled back into right hand lane and stayed there for quite some time. I then turned off the all around sensor @ and it didnt do it again but as i got closer to home the warning light came on and a message popped up. It now has the triangle caution sign on and the picture of car icon in amber. I had driven the car from my home for about 50 miles and parked car for two hours, the drove back toward home for about 20 miles when the event happened. It was dangerous and makes not want to use any of the "assist system's" going forward. I plan to wash the car today to see if the lights will go off- if they don't then i shall call dealer on Monday. This occurred on saturday. Ill be washing car today (sunday). If i had anyone driving closely behind me, i for sure would have been rear ended.

Vehicle was parked for an hour facing south. When vehicle was started, forward safety and blind spot monitoring warnings came on and many other systems tied to forward camera were disengaged. Mileage: 123k. Power steering was unresponsive and brakes felt spongy. Disconnected battery and let sit for a day. Reconnected and issue went away. A week later, was parked at hospital facing south for 4 hours. Issue came back, this time disconnecting battery did not fix issue. Dealer currently has the vehicle and they are claiming it shows rear end damage even though the car hasn’t been in an accident since I was rear ended and car was repaired. Dealer reported over 80 body codes including blind spot monitoring radar.
