2024 Hyundai Santa Fe Hybrid

On a bright sunny day, the Hyundai Forward Attention Warning (FAW) SHUT OFF my adaptive cruise control while doing 70 mph, indicating that I was not focused on the road. I was looking straight ahead at the road the whole time. I later determined that the system was reacting to glare on my glasses (not sunglasses, no tint whatsoever, just glass). This led to a very dangerous condition because I was fighting with the car to determine what had happened (at 70 miles per hour), not focused on the road as I just had been prior. The system is checked as OFF in setup (as described in the manual) but clearly that was not the case. The driver CAN NOT shut the system like the manual says. I actually love the car, EXCEPT for that "feature". This subsystem should never have been permitted into a production vehicle and, had I known, I would never have purchased. It's that big of a problem. The system appears to be very dependent upon ambient light because I never have this issue when it's cloudy, raining, or at dawn or dusk. I have complained at 2 Hyundai dealerships here in the Chicago area, to a total of 4 Hyundai personnel, even sent a video my daughter recorded of me driving and exhibiting the issue. In 3 of the 4 cases, they replied the "system was performing as designed". That appears to be their mantra. The one service person replied that they had never heard that before. I guess they don't ever check Reddit or write down my many complaints. I think it's clear Hyundai, as a service organization does not intend to do anything about this and, perhaps worse, the company at large has no intention of doing anything as this same subsystem is part of an extensive line of their 2025 models as well.

Traveling back from Aurora Co to Iowa the Heating stopped working in three hours of our trip. A code came up and the Heating shut down. Which allowed the windshield to be frozen over while I was driving. Rain freezing to the windshield. Had to stop frequently because of code P007100. Hyundai relies on an ambient temperature sensor for heating within the vehicle. It froze over while Hyundai relies on an ambient temperature sensor for heating within the vehicle. It froze over while I was driving was driving. Other cars were driving just fine because they didn’t have heat within their car. So Hyundai needs to have a special recall on this for a safety concern and cold weather.

I had my vehicle serviced at Hyundai of Kirkland, located at 11800 124th Ave NE, Kirkland, WA 98034, on December 19th, 2024. During the service, the dealership did not inform me of any active recalls on my vehicle, nor did they address any recall-related issues. I believe it is their responsibility to notify customers of recalls and ensure proper servicing as required.

2024 Models appear to not allow disabling the "Consider taking a break" alert even when disabling the "Driver attention warning" feature. This alert appears to go off on imperfect roads at seemingly random intervals when the car "thinks" you are driving improperly. The alert is abrupt, jarring, and unsafe in my option. I have no idea why they would release a model where you can't disable it when in previous models you easily could. It appears this is a common problem from my research online and I don't think Hyundia has made any steps to fix this.

We purchased our '24 Santa Fe hybrid on 9/18/24 new with no problems. On 10/8/24, about three weeks later, I was stopped at a stoplight after exiting the freeway. When the light turned green, I accelerated and felt a clunk, then the car would not accelerate past about 30 mph. Several warning lights came up on the dash. I could hear the engine revving, but it felt like it wouldn't go into the next gear. I thought I could make it to the dealership, which was only a few miles away. But at the next stoplight, I was stopped in a turn lane, and when I pushed on the gas nothing happened. I tried shifting back and forth from park and restarting the car, but nothing helped. The car would not accelerate at all. CHP shut down the intersection and helped me push the car to the side of the road, where I waited for a tow truck. The car was towed to Folsom Lake Hyundai, where it was purchased. Warning lights said "Check hybrid system," "Transmission control system" and "Driver assistance system." The app listed these codes under POWERTRAIN issues: DTC P198500, DTC P178400. We picked up the car from the service center on 10/11/24. They said a wire came loose from the oil pump, so they reattached it according to factory direction and it's fixed. 5 days later, on 10/16/24, the car stalled again. This time on the freeway. I entered the freeway and accelerated, then felt a similar clunk and got the same warning lights. This time, the car would not accelerate at all. I stopped on the side of the freeway and was towed to Folsom Lake Hyundai again. It took almost 2 weeks to repair, but they said the same thing happened again. The same wire came loose, causing the car to stall. Their solution was to reattach it again and wish me luck. They said maybe I drove on a bumpy road, but there's nothing else they can do but reattach it and get it out the door. I do not feel like this is an adequate repair and we are now worried that the car will stall again in the coming days.

If am wearing my sunglasses or I am holding the steering wheel in a certain way my car will assume I am not looking at the road and turn off my cruise control. If I do not take my sunglasses off right away or move my arm my car starts breaking and alerts me to take control of me vehicle. My driver Attention setting is off. I have almost been rear ended twice because of this. Hyundai has acknowledged that is this a serious design flaw and a safety concern but has no solution

Brand new vehicle purchased through Clement Hyundai. Within a couple hundred miles, multiple times vehicle goes into neutral on its own while driving. Have to stop the vehicle and turn off engine to try to get it into drive to get off the road. Takes several attempts to get into drive. Major safety hazard! Repaired once by Jefferson City Hyundai. Same problem happening again. Car not drivable as it is a safety concern. Have found multiple online forums wherein people are having the exact same problem.
