2023 Hyundai Santa Fe PLUG-IN Hybrid

While operating the vehicle, the cruise control turns off without any warning. The warning messages that come up only after the cruise control is turned off by the vehicle state "Smart cruise conditions not met" and "forward safety system disabled. Radar blocked". This disables the vehicle from utilizing cruise control in any manner. This happened on the highway with the cruise set at 72 mph, with a semi truck right behind my vehicle in moderate traffic! The semi slammed brakes on and after initial shock, I was able to accelerate the vehicle somewhat to avoid a collision. The dealership claims that "ALL" new vehicles do this when operated in wintery weather, snow, or mud kicked up from the road, or when sensors get iced over. They claim that there is NO reprogramming that can be done to fix this HUGE safety issue. I have NEVER heard of this or experienced this in any other vehicle other than this Hyundai Santa Fe! As a disabled veteran, this honestly scared the hell out of me and makes me very leery to operate the vehicle in the wintertime time and I am the primary driver for the family! At the time of the incident, it was not snowing, the temperature was approximately 36 degrees, and the roadways were clear of snow or ice! The only thing that could be noted was that the roadway was wet, and after stopping, there was sand or salt film in the front of the vehicle. As a disabled veteran with a lower back injury and radicular pain down both legs, I rely on a vehicle's cruise control when driving more than short distances, in order to not cause lower back or leg pain while driving! This issue with the cruise control stopping operation and not allowing the cruise to be restarted is both a HUGE safety issue for both the operator and all vehicles around/near the vehicle on/at highway speeds, and a violation of the ADA (Americans with Disabilities Act). With no way to reprogram or reset this awful feature, the Hyundai Santa Fe is unsafe for disabled individuals.

My horn isn't working as designed but when I push on steering wheel feels like it's cracking or breaking behind it. My front axels from factory were out of balance causing a vehicle vibration from 80+km/hr. Dealer thought it was tires not driveline. Different dealer diagnosed it as both axels in front. Issue was repaired once parts were available. Vibration still is evident but think its tires. Trying to get hyundai to replace tires now as its consequential damage. In November 2023 I was involved in a accident where the front collision warning and assist system didn't engage properly as when it did inwas in the danger zone already. And when I applied the brakes the steering became stiff as to mimic loss of power steering. I couldn't turn out of the accident and couldn't avoid it. Have video of this on my dash cam. I have a warning light rhat comes up on my dash saying check turn signal dealership verified. They have ordered the ICU junction box (fuse panel) but its been on a back order. Till February now. But no stored codes ever stay on my ecu or bcm.

On several occasions, the Automatic Emergency Braking System engages even though there is no evidence of a dangerous situation or imminent crash. It usually occurs during highway driving or at speeds over 40mph. In each case the brakes engage, the steering tightens, the AEBS notification appears on the dashboard and an alarm sounds. After a few seconds, the brakes and steering return to normal. This occurs even when there is no evident traffic issues. I googled the situation and found that other drivers of this car have had similar problems. Here are links to that result: https://www.santafeforums.com/threads/emergency-braking-system-activates-intermittently.17221/ https://www.carproblemzoo.com/hyundai/santafe/automatic-emergency-braking-problems.php I suggest that the NTSB open an investigation into whether this is an ongoing problem.
