Adaptive Cruise Control Problems of Hyundai Santa Fe - part 2

The sensor always goes off stating my eyes aren't on the road to the point it trys to stop the vehicle in traffic. This prevents me from being able to use cruise control because the sensor is causing issues by not detecting my eyes.

The forward attention warning (faw) on the 2025 Hyundai Santa Fe calligraphy can not be deactivated. Correction, it can be turned off for normal driving. For instance, driving around the city or not using Smart cruise control. As soon as you turn on the Smart cruise control it's reactivated and can't be turned off. The faw does not work when using prescription sunglasses / non prescription sunglasses or if the sun is hitting the inside of the cabin a certain way. The faw constantly flashes warnings and beeps at you even though you are looking forward and keeping your eyes on the road. If you look far down the road you shift your eyes up some, and the system beeps and flashes warnings to keep your eyes on the road. On a recent 230 miles trip I did not wear my prescription sunglasses / non prescription sunglasses and the faw system went off at least 50 plus times and I had my eyes on the road at all times. Very distracting, I then had to take my eyes off the road to see why it was beeping and telling me to keep my eyes on the road. The faw system actually makes for a stressful and distracting drive. At this time the faw is useless. I took the vehicle to the dealer and the faw is not a system that can be turned off. Hyundai needs to allow the dealers to be able and deactivate the system.

In January, 2024, my vehicle (2023 Hyundai Santa Fe) started shuddering when brakes were applied at high speed, on quick or hard stops, in stop and go traffic, and especially going downhill. I had only been driving the vehicle for about 5 months. I took the vehicle to an independent mechanic, who explained that my front rotors had burn spots. He recommended that I have them resurfaced. I did not want to pay for the problem to be fixed when I believed it was a factory defect and should be covered by warranty. I asked the mission hills Hyundai dealership service department to investigate and correct the problem, because I felt that my family's safety was jeopardized by faulty brakes. They showed me the burn spots on the front rotors and recommended resurfacing. They said I could wait for the pads to wear down and do the resurfacing at the same time as the pad replacement. Their estimate for resurfacing was higher than the one from my mechanic. I found a Hyundai technical service bulletin, number 23-br-004h, which described the exact defects of my vehicle. I returned to the dealership with the TSB in February, 2024. They replaced the two defective front rotors and front disc pads at no charge. The shuddering was no longer evident, and I thought the problem was resolved. However, 10 months later in December, 2024, I once again experienced the shuddering while braking on the freeway while going downhill and when slowing for stops from high speed. Since I had been told that the new rotors and pads were covered by warranty for 5 years or 60,000 miles, I returned to the dealership on 1/16/25 and asked them to evaluate the brakes again. They said that the front rotors again had burn spots. They once again recommended resurfacing at a cost of $249. I reminded them that there was a warranty on the new parts, they claimed that the only warranty was for the original parts that had been replaced. They agreed to resurface no charge. Please investigate and respond to my complaint.

The brake light switch is malfunctioning and causing the brake light to stay on continiously. This is dangerous because the brake light stays on so theres no indication that I'm getting ready to stop because the light is already on, increaseing the risk of a crash. The cruise control is also afecteced with this issue because it stop working at the same time. I looked up the recall and it said that 2013 -2015 hydundia Santa Fee sport vihecles were affected, but when I call the dearlership they said my VIN# was not included in the recall!.

This vehicle has a driver attention alert system which track driver's eye and head movement to determine driver attention levels. This system can be disabled outside of using cruise control through the setup menu. However, when in cruise control, this system cannot be disabled. Unfortunately, if you're wearing sun glasses the system declares the driver is inattentive and produces a distracting aural and visual warning. If no action is taken the vehicle will automatically come to a stop, even on the freeway! this option is a driver distraction and does not allow the driver to wear sunglasses increasing the risk of motor vehicle accidents. Several customer have complained to Hyundai about this system. There needs to be driver-selectable option to enable/disable, even in cruise control mode.

The cruise control uses a camera , the is supposed to watch your eyes , to make sure you are watching the road . Unfortunately , if you are wearing glasses ( which I must when I am driving ) the light reflecting off them makes the unit think I am not watching the road . For backround, I was a highway patrol offiger for 30 years . I am very attentive to the road ahead of me . It seems Hyundai knows of this problem , which suddenly disengages the cruise control , causing rapid deceleration of the vehicle . At highway speed , this is very dangerous . It has been noted on many forums , and my dealer knows about the problem , but there is no way to disconnect the camera from the system . This is really an accident waiting to happen .

Currently have 518 diagnostic history codes (dtc)in memory. Additionally, I have 3 active dtc’s. The codes are: dtc c160c87 dtc system chassis dtc sub system lkas, and dtc c160c87 dtc system chassis dtc sub system scc, and dtc c163881 dtc system chassis dtc sub system scc first occurrence: during actual assembly in montgomery, al plant. I have asked three Hyundai service dealers for help. All have tried. Noting noted that contributes to the issues above. At first, my dealer replaced the front camera. Was told it was a heating issue. I have contacted Hyundai bluelink service for help. An information report was filed, twice. The first report I received feedback that Hyundai’s engineers had corrected the issue. On the following day, the codes returned. A second concern was filed with Hyundai bluelink. Hyundai motor America case#: [xxx] to wit: “thank you for contacting Hyundai motor America. We are in receipt of your e-mail and one of our representatives will get back to you shortly. Sincerely, Hyundai motor America” is my vehicle going to fail and cause me injury while operating it on an interstate highway? this is quite concerning as I drive my car. All I want from Hyundai is to get this issue repaired. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

If I wear dark sunglasses, the forward collision avoidance turns off while using cruise control. If I wear lighter sunglasses, it is fine. Unfortunately, I have to wear darker sunglasses due to previous eye surgery. I am unable to utilize cruise control without compromise to my eyes because forward collision avoidance doesn’t work with darker glasses. This happens every time I test it and change sunglasses with differing shades of protection.

I was driving on the highway going about 75 to 80. My vehicle will start warning me that a car was in front of me when the cars was about 3 to 4 car links ahead of me. The emergency brake will start for at least a mile down the road. Then shut off. It will happen at least 5 times on a 4 hour trip. This really need to be fix before someone get rear end.

I've been driving in arizona on southbound 101 just south of w guadalupe rd and noticed an issue that is very odd. I have a 2023 Hyundai Santa Fe that has highway driving assist that does both speed control and distance from the vehicle ahead of me and lane keeping assist. After I pass guadalupe, but before an overpass for the sun cir trail, my vehicle, if those systems are on, goes haywire and all those safety systems turn off. I have experienced it on at least 3 of the lanes on that stretch. It happens both early in the am and later regardless of sun. It doesn't happen on northbound. As more cars have these features, this interference should be looked in to. I have not experienced this on any other of our highways. Here's a link to the the rough location. Https://maps. App. Goo.

Caught on fire while driving, total loss unknown reason nor any warning. I stopped because of rotational noise to check tires, then car burst intimate flames. State troopers assisted and report filed.

We noticed that we had our airbag light was on in our dashboard along with that we also notice that the buttons and horn did not work in to the steering wheel. When we took the car to get checked by the Hyundai dealership in lakewood. We were told that the clock spring was the cause of this problem to the airbag, horn, and the buttons not working. They told us that this clock spring part it was broken and it needed to be replaced. Our concern is the number one safety which making sure that all of the airbag and horn to be working. When this was communicated to the dealership person he response was that he could not say anything much about other then him saying that it was not under warranty and it was due to the mile of the car. Which I the moment we told them we totally understand about warranty and miles to the car but the safety of someone should not be put at risk just because of one part that connects all of this things. To us this is safety concern due to the airbag and horn not working. We are not sure by us reporting this would be something can be considered for a recall or be done about without costing any money to those who own a vehicle like this.

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.

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 an interstate highway at approximately 75 mph. I had cruise control activated. Suddenly the car dramatically slowed down, accompanied by rapid beeping noise. Luckily, there was no one close behind me.

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.

The forward collision avoidance system is malfunctioning and shuts down the traction and stability control systems making the vehicle more vulnerable to collisions. Multiple attempts to repair this system have been unsuccessful.

I was driving on the highway in a mountainous area going downhill. The cruise control was on with the speed set at about 80 miles/hour. Then the car was losing speed, the rpm needle started swinging from left and right. I stepped on the accelerator but the car continue losing speed to 40 miles/hour and continue losing speed. I turned on the emergency light to warn the other drivers and was able to move the car to the shoulder and stopped it without an accident. But the cars behind me could have smashed into my car that day and that would be the last day for my mother (in the car at that time) and me. The car had 41000 miles on it and we had the maintenance done just recently. I did not notice anything else abnormal before the incident. We reported the problem to the dealer and have to pay for the dealer to inspect the car. The inspection has been scheduled but not done yet.

Hi team, issue 1: unexpected acceleration: recently I found that is there is unexpected additional acceleration when I press gas pedal initially after changing gears from p to d. I am setting up an appointment with dealer to report and investigate this issue. My car has only around 13000 miles on it. This issue was initially observed when one morning when I headed somewhere there is unexpected acceleration when I slightly press gas pedal. Issue 2: the advanced driver assistance systems (adas) doesn't work properly when set to adaptive cruise control. It doesn't slow down /stop when getting close to cars parked at signal specially as slight curvy roads.

It all started on Thursday, February 16 when I went into my garage and noticed a strange chemical smell and my car battery was dead. My husband replaced the battery that night, but we noticed the break lights stayed on. When took it to a firestone department on Friday, February 17, they replaced the battery terminal and ran diagnostics. We finally called and got an answer on Monday, February 20. The mechanic said it was the abs control module and wiring harness. We transported the car that Monday afternoon to the local Hyundai dealership, which we really didn’t want to deal with since we haven’t had nice experiences with them in the past. They never called us and when we finally got ahold of the service department on Wednesday, February 22, they stated that they believe that it is the abs control module, but they are unable to fix it locally. We would have to send it to another Hyundai dealership which is about 100 miles away. After speaking to the Hyundai corporate office, they suggested with previous recalls to place an incident report. The recall for the abs systems for Hyundai came out on may 16, 2018 and the recall number 218. The recall includes cars with the cruise control systems.

Driving on highway and car engine light came on then car engine kicked down like it was going to stall then drove normally then kicked down again . Kept kicking down , drove it home and shut it off. The car starts but is knocking and the engine light comes on and blinks constantly .

I was driving my Santa Fe into my garage and there was a misfire in the engine. And then it stopped running, I have had it parked there now for 1 month because I don’t have the money to put a engine in it ,.

Vehicle spontaneously caught on fire in the engine compartment while driving in a parking lot. Within 30 minutes, the vehicle was incinerated down to the frame. Prior to this incident, a warning had flashed on the message center that the adaptive cruise control system was being disabled. It is pending insurance inspection and we are trying to contract Hyundai. The police report is not available yet, but is with the faribault, mn, police department and is #22-3714.

(service brakes, hydraulic, exterior lighting, recall started in 4-1-2013, recall #13v113000. Car was brought to authorized dealer on the same occasion as mentioned below and told the vehicle did not need that repair performed. ) (air bags : frontal sensor/control module, recall started 7-24-2012, recall #12v354000. Car was nbrought to authorized retailer and told Hyundai no longer makes the part in order to resolve this issue. ) there are 5-6 different lights, all of which are mentioned for the recalls as stated above and seems to be a solvable issue. I just don't want to learn one day that my husbands cruise control did not disengage and he collided head on full speed. Hyundai needs to to start producing the part in order to fix the cars or recall them all together for fear of multiple lawsuits. Photo evidence of dash lights and screenshots of recalls can be provided upon request.

Smart cruise control relies on the inconsistent and consequently unreliable performance of the of the front-mounted radar. Otherwise-reasonable operation of the cruise control would abruptly terminate 1/3 to 1/2 of the intended use-time, illuminating the master warning light (the amber triangle with internal ‘!’) that was accompanied by either a ‘1’ or ‘2’ encircled by red and may or may not have included the collision-avoidance warning light. Subsequent examination of the rectangular shield in the center of the grill very rarely revealed more than 2 bug remnants. When the Smart cruise control was in operation it would abruptly apply the brakes when approaching or passing a truck in the lane to the right. There appeared to be no similar conditions to the size or shape of the truck or trailer when these events would occur. None of these events applied to congested traffic conditions, just otherwise open road. The ’21 Hyundai Santa Fe does not appear to accommodate any mechanism to revert to conventional cruise control, omitting the influence of the erratic front radar system. Trips to two dealerships have yielded no redress to this malfunction.

This vehicle is the first Santa Fe that only comes with adaptive cruise control and there is no way to disable it and set regular cruise control. Here are just a few examples of the safety risk. We were on state highway 29 which is a rural 4 lane highway. There were 4 cars near us. Our cruise was set for 70mph. A vehicle came in front of us to pass which it did. There was no issue. However, our vehicle saw this as a threat and our vehicle slowed from 70mph to 50mph until the other vehicle was out of the set car length distance. Meanwhile the other cars around us had no indication or warning why we would have slowed down this much and we were nearly rear ended. There was screeching of tires and brakes suddenly applied by the other vehicles. All for nothing. I am on the highway with the cruise set at 75mph when again vehicles will come in front of me and my vehicle slows from 75 mph to 54mph, causing the surrounding vehicles to not know what is going on and I hope they are paying attention because there is nothing really going on other than normal driving. It is terrifying to have your vehicle control itself and you don’t know when it will start to accelerate again so for the most part, I am shutting the cruise control off and on constantly. At our most recent Hyundai service appointment for this problem, we were told by Hyundai care manager that this is exactly how it’s designed and there is no problem. And we’ve been told just simply don’t use the cruise control at all. That is not a solution. We feel like all these “safety” features are creating a sense of driver coma on our roads. Instead of the left lane being used for faster cars as a passing lane, the adaptive cruises are creating a chain of vehicles that are well under the speed limit.

A car in front of me lost control and I braked to avoid an accident but the car turned and had no stability, forcing me to maneuver it to avoid crashing by leaning on my neck.
