What 199 owners told NHTSA about the 2023 Hyundai Santa Fe Hybrid

Occasionally the cruise control when accelerating will exceed the set speed and continue to climb and I will be going 20 miles faster than the set speed and climbing. The only way to sop this is to turn cruise off, slow down and restart. My thought is it happens after I have disengaged the cruise and then when safe reengage which is done by pressing the switch straight down. In my previous vehicles I would push the control up. I may be doing this by accident and giving the system an unknown command. Whatever I am doing to create tis situation is too easy to do and creates a safety issue. this has happened multiple times.

The front collision warning/assistance system on this vehicle does not appear to be working. The dealer claims that it is working. It seems that the protocol for testing for proper function is flawed and no one is tacking ownership of this issue. They are saying that in order to test the system a near collision must be imminent and to simulate this puts the technician at risk of injury (understandable); Nevertheless, I have been in situations where I should have at least received a warning and there was none. On a test drive by the service manager with me in the vehicle the front collision assistance was verified on and active. The cruise control function was tested and worked to adjust the speed of the vehicle appropriately which tells me that assistance is available. It appears that the either the collision sensor is not recognizing collision danger or the danger message is not getting to the warning trigger and possibly the assistance trigger. This situation should be reported to the appropriate department a Hyundai for review.

Over the last Tom th, I have encountered some pretty scary issues with my brand new Santa Fe purchased in April. Last week, while driving, after I turned on adaptive cruise control, the system alerted me that “smart crusade control conditions weren’t met” and kept trying to engage the front left brake — this occurred three days in a row. After turning off the smart cruise control and entering residential roads, the front left brake tried to engage in a manner that seemed consistent with ABS issue. I brought car in two days later to Dublin Hyundai and they said they couldn’t find anything wrong with it. I picked the car up yesterday morning and then last night while driving on the highway, it alerted me that I need to “check highway drive assist system” and a warning light came up. After about 5 minutes, the car jerked me incredibly hard to the left on the freeway and then athe light turned off. Then two days ago, I was driving my car on the highway the car randomly said “emergency braking system activated” twice, while going 70 on the freeway in the middle of nowhere. This was while driving safely and no cars nearby either time. I looked online and it appears this is a problem that’s occurred in many Santa Fe’s, so there is clearly an issue with manufacturing (which I’m assuming is the same case as the previous issues I’ve run into).

I was driving on the highway and the car phantom emergency braked for no reason at all.

Driving on highway with cruise control selected to 80 mph. Left signal is applied to travel to left lane to pass a semi trailer. When the vehicle is half way into the left lane, the automatic system applies hard braking even though the semi trailer has not been detected as too close. Vehicle slowed to 74 to 75 mph before cruise control was turned off. Vehicle behavior is a total surprise to vehicles following since the braking is unexpected on a clear road. Repeated the symptoms several times. This braking does not occur if the vehicle ahead in the right hand lane is an automobile. This only occurs if it is a large vehicle such as a semi. Moving quickly or slowly to the passing lane affects the total time the braking is applied. The slower the movement, the longer the braking is applied. Repeated this behavior at 75 mph and 70 mph with similar results.

All lights that come on when you first start the vehicle stay on. ABS, forward collision, rear collision, side mirror check, down hill brake, etc. The brakes and brake pedal would lock up when attempting to brake. Pedal stays locked but the wheels didn’t seem too. Brake system wouldn’t respond to pumping the brakes the pedal stayed frozen. It could have caused me a serious accident.

I bought this Lemon on 1/14/2023. The front collision detection doesn't brake to avoid collision. The Emergency brake will engage on it's own, and it has to be manually disengaged. The parking assist feature will automatically disengage and is unable to engage it. The middle seat in the back seat headrest obstructs a major portion of the rear window, obstructing the driver's view. It is not the headrest pictured in the Owner's Manual. It has been in the shop twice. It has been in the shop for 10 days and counting of the 34 days I have owned this lemon of a vehicle. The car was taken to the dealer for repairs but consumer was told the vehicle functioned properly. The consumer stated the car was still malfunctioning so vehicle was taken back to dealer for repairs and still being assessed.

I purchased this SUV new and noticed an issue with the automatic intermittent wipers. The dealership has replaced the windshield sensor and issue is now unreliable at best. Service department told me to simply wipe the sensor off or pour water onto the sensor to get the wipers to work. That seems to work for about 3 wipes and then stops again. Also, the driver seat changes position by itself while driving, and the advanced cruise control failed to provide any braking and almost caused me to rear end a stopped car in freeway traffic. Additionally the advanced braking system does not work at all... I had the salesman check the settings and they are turned on, but do not provide any braking function. The alert system does provide a warning if a car turns a corner in front of me, but fails to take any action.

Forward collision warning system engaged unexpectedly, braked hard to the point of smelling burnt tires. No collision imminent. Normal driving conditions. On a second occasion, stopped at a traffic light, the vehicle suddenly warned of foward parking collision. Front camera engaged and yellow warning showed
