2023 Hyundai Santa Fe

It is not just this vehicle; it is ALL vehicles with adaptive cruise control and automatic emergency braking. When sensors get snow or debris on them, they shut the vehicles down without warning. I have had 3 times this winter when the roads were fine, cruise control set, and because another vehicle was kicking up road salt, the vehicle instantly shut off the cruise control without any warning to the driver, all 3 times I had traffic behind me at 55mph or on the highway at 70mph. The emergency braking is another issue, as it will bring the vehicle to almost a stop, and does not take into account if there are other vehicles behind it or not! How more people have not been killed because of these 2 systems is beyond me! BOTH of these systems and the vehicle they are on NEED to be recalled and either sensors removed or workarounds implemented, that at least give the driver some advanced notice before the cruise control is turned off or before a vehicle decides to hard-brake itself!

Today, i received an extended warranty for my horn. There is a known issue with water getting into the horn and causing them to fail. Upon researching this, people have reported having their horns changed several times. This is a safety matter that an extended warranty is not fixing. Please enforce a recall so that this matter may be properly resolved. Canada has already issued a recall, I hope we can do the same. Thank you.

On March 4, 2026, at approximately 7:30 AM EST, while driving my 2023 Hyundai Santa Fe Limited on [XXX] , the vehicle experienced a sudden loss of propulsion while traveling at approximately 70 mph (posted speed limit). The vehicle would not accelerate or maintain speed and would not move forward when placed in drive, indicating a failure within the powertrain/transmission system. The vehicle is currently located at a Hyundai dealership and is available for inspection upon request. This incident created a significant safety risk, as I was traveling at highway speed in active traffic when the vehicle unexpectedly lost the ability to move under its own power. This placed me at risk of being rear-ended and made it difficult to safely maneuver out of traffic. The vehicle was inspected by a Hyundai dealership. Diagnostic trouble code P284001 (Shift Fork “D” Position) was identified, and I was informed the failure is transmission-related. The condition was reproduced by placing the vehicle in drive, at which point the vehicle would not move. The vehicle has been inspected by the dealership. The manufacturer has been notified but has not physically inspected the vehicle. No police or insurance inspection was involved. There were no warning lights, messages, or prior symptoms before the failure. The issue occurred suddenly without any indication of a problem.

I have been fighting this issue now for 2 years, vibration while driving interstate speeds, especially right rear seat. I have had tires replaced twice trying to fix balance issue only to find out that one rim will not road force balance correctly, even with tire matched it only reduced road force balance to 20lbs (30lbs with out match). I have had it at discount tire and Gettel Hyundai of Lakewood ranch, FL several times. Hyundai sent a senior tech to look at tires, did not speak to me to get explanation of my concern, did a balance, got same numbers and said was good to go. My other 3 rims have a max road force of 12lbs without even being matched. This causes vibrations when driving, extra wear and force on the tire and is a safety concern. This rim is the issue and Hyundai refuses to fix it.

Driving to work and a loud noise (pop) was heard and then I realized the sunroof had basically exploded. Glass was all over the car and all over myself. I immediately got off the road and turned on my hazard lights to assess the situation. This could have caused an accident had I not remained calm. Contacted dealership this morning. Waiting to hear back. No prior warning to this happening.
