On [XXX], while I was travelling South on [XXX] in Washington, while towing. My Emergency Brake/Forward Collision Avoidance system activated. Very briefly but enough to give me a shock. There was no reason for this to be activated, traffic was moving along, no one was closely in front of me, fortunately no one was right behind me. I discovered upon returning home that there was just issued a recall for this reason on 2025-2026 Santa Cruz vehicles. Mine is a 2024. I called the dealership, no coverage for the update for my truck yet. There was another recall that I was not notified about for an software update on my oil pump, which I will have done tomorrow.

My issue is that the lane keeping system was much too sensitive. I would be riding at highway speeds and the car would pull suddenly to the right or left. This was an intermittent problem but when I took it in wanting an adjustment to the system to make it less sensitive, I was told that they were unable to address the system-not allowed to make any adjustments, which I found to be strange. I asked to speak to the service manager and waited to speak with him. The service advisor came back to me, gave me my keys and said it was now fixed. I asked what they did and was told that they disabled it and offered NO PAPERWORK. I reached out to Hyundai corporate and was told that they don't get involved with customer issues with their dealers. They told me to work it out with the dealership. Is that how safety issues are supposed to be handled?

We purchased our 2024 Santa Cruz [XXX]. On [XXX] the Santa Cruz we purchased from Korum Hyundai Dealership died on the highway as my husband and I were heading to town through the mountains. We had to roll to the side of the road as the Santa Cruz just lost all power and would not accelerate, it just died and lost power. I thought it was a fluke. My husband was driving. I asked if he had hit a button or something, he said no. Turned the ignition to off and he restarted the Santa Cruz and it turned on. On Saturday, [XXX], driving on [XXX] , heading west from Glenoma, Washington to Morton, Washington driving approx 60 mph when the Santa Cruz lost all power again driving down the highway. It was a very dangerous situation! We have logging trucks and semi trucks up and down that highway going speeds of 60 mph and more! I lost all power and had to roll to the side of the road in the Santa Cruz. Some of that stretch of highway does not even have places to pull over and some of that highway has metal guard rails as well as drop off cliffs. EXTREMELY HAZORDOUS SITUATION to have the Santa Cruz simply lose all power going down the highway! On this date the Santa Cruz had 4522 miles on it. I looked at the dash panel to see if there were any warning lights and made a point to look at the mileage. There were no warning lights. Nor warning messages. April 3rd the 2024 Santa Cruz Night was dropped of at the Korum Hyundai Service Dept. The dealership has had the vehicle for 3 weeks and states they cannot replicate the problem. There are no warning lights. Since then I have been on Hyundai Forums and have multiple people tell me the exact same situation has happened to them. They ended up finding out it was the fuel injectors. The forums also stated that the dealership could not replicate the issue when take to service department for other owners.

When the lane keeping assistant is operating, a constant, fairly loud buzzing sound emanates from the steering column, accompanied by a slight vibration on the steering wheel. When driving at low speeds and in traffic jams, this makes you nervous and distracts you from driving. The dealership cannot identify the problem and determine the cause. This sound has not been noticed on other cars of this brand

I was traveling from Tennessee to Indiana on [XXX] going about 76 mph. I attempted to switch lanes and at the same time the other vehicle decided to speed up as the semi behind started speeding up. When my 2024 Santa Cruz Turbo (which only has 12,000 miles) jerked and started slowing down, the check engine light came on and it started declining acceleration. I mashed the gas and nothing happened (I was in Normal MODE- not smart mode, not sport mode, and not snow). I literally almost died as 2 very large trucks are coming at me full speed as I'm descending speed. I swerved off the road into the grass medium and was able to get out alive. However, the Hyundai is still not accelerating the RPMS will go to max and I’ll only be at 50 mph. I googled online and apparently this is been going on since 2022 with a several of Hyundai cars not just Santa Cruz; The Tucson, Santa Fe, and Santa Cruz were just some of the reports I read. I have a video however it will not allow me to upload it. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
