Adaptive Cruise Control Problems of Hyundai Tucson - part 1

The computerized "safety" features on this car can not be turned off. They pose a hazard in a number of ways from when the car is stopped to driving on multi-lane highways. For instance, the adaptive cruise control is linked to an over the air network. If that link is "cut" by going through the mountains, cruise control suddenly quits; this has happened while passing a vehicle over a mountain pass. When attempting to pull out from a parking spot, another driver stopped to wait for me because they wanted my parking spot. My car stopped by itself, sounded a loud noise, steering wheel shook, my wife screamed at the noise, and I had to shift out of reverse and shift back into it and attempt to leave the parking spot. When driving in the mountains on curvy mountain roads, my eyes shift around a great deal to keep on top of the road and traffic conditions. This sets off the "its time to take a coffee break" announcement with accompanying dinging. This continues every few minutes until I am out of the mountains - it is distracting at the least. If the adaptive cruise has slowed the car down because of slower traffic ahead, and after a car passes in the outer lane, you pull into that lane to pass the slower car; but when you do, my car accelerates quickly to bring the speed up to the speed set on the cruise control. If the car that just passed is too close, this acceleration sends us hurling toward the other car. I would like the ability to turn these "safety" features off. But that is not possible with the 2025 model - while it was in earlier models. Though I recently purchased this car, I am investigating other cars to replace it almost immediately because I want to be able to drive without these "safety" features making poor decisions and putting my life in danger.

This vehicle is a pile of hot garbage. Front end collision system slams on the brakes when you are not even close to hitting something in front of you plus it will auto brake randomly but often. I was backing into a parking spot and someone walked in front of the car and it slammed on the brakes. Dealer says only way to fix this is to turn the entire safety system off. The coffee break warning has zero rhyme or reason and will go off 10+ times in a trip even though I am not distracted and use my turn signal changing lanes. Dealer states there is no way to turn this off. Dashboard randomly flashes and goes dark along with all lighting in and outside the vehicle. Dealer was unable to duplicate the problem and returned the car with no fix. Drove the car in the rain for the first time and dashboard came up with a ton of errors and crash detection turned off. This is new and will be taking the car in for this and is now the reason I am filing another complaint. This vehicle is not safe and can be very scary to drive because you don't know when it will just take over for you.

On long road trip from TX to MA started before dawn and route initially [xxx] . With sunrise route was into sun and so I used my sun glasses. Within a few minutes a warning gong and light on instrument panel litup. I did not know what the cause was and then unannounced the adaptive cruise control lane holding and steering shut off and the vehicle seemed to brake quite vigorously. There were a few cars behind me and due to my vehicle suddenly slowing down they had to brake unexpectedly. They then honked at me and passed quite aggressively and gesturing their displeasure with me. I called Hyundai tech support they where of no help. I asked for a manager - who called back and I was told it is because I used my sun glasses! I was told it would always happen if sunglasses where used and I could not cancel this feature without disabiling the "safety" features that I considered when purchasing the vehicle on 24th [xxx]. I was told I should not use polarized glasses which my pair is not in any event. I requested to speak to a more senior rep and the next day received call from a Hyundai rep who stated there was nothing I could to over come this nuisance feature and if I didnt like it I should not have bought the car. I stated I did not know this could or would happen ! in addition every 5 to 10 minutes a warning gong,light and speech notice keeps on popping up and states "I need a rest". In my opinion too, it is also a safety issue as it is a nuisance and consistant and at inopportune times blocking gps commands some times etc. These features, in my opnion, are too frequent too persistant and not helpful. There should be a way for the owner-drver too disable the announcements but have the benefit of the features ie adaptive cruise lane and steering etc without the car deciding not to allow because sunglasses are needed. That does not enhance safety in my opinion. In my opinion the way it is programmed it is a safety hazard just suddenly slowing down information redacted pursuant to the freedom of informa.

I recently purchased this car and just took it on our first highway trip of about 1100 miles. I experienced three problems that are a safety concern. 1. "need to take a coffee break notification. " this comes on frequently and is distracting. No need to have that come on. When driving in heavy traffic at speed, this is too distracting. There is no way to turn it off. 2. Camera focused on the driver. If I take a drink from my water bottle, looking around the water bottle to see the road, the camera can not see my face/eyes. It then shuts off my cruise control, makes a noise, scares my wife, and distracts me from driving. This has happened to me in heavy urban traffic going through cities on my last trip. 3. The cruise control is linked to communication from outside the car. When driving in the mountains, there are times when the signal is lost, the cruise control stops working, the car emits a noise signally a problem, my wife screams, I lose concentration on what is going on as the car decelerates quickly and the semi truck behind me comes very close to the rear of the car. Potential accident caused by this silly system. There is no way to disable "adaptive cruise control" and resort to a system that does not rely on outside communication. The car has about 3000 miles on the odometer and I am ready to trade it in/get rid of it. I am greatly disappointed.

I was driving my new 2025 Tucson on a 2400 mile trip. On the way back the entire dashboard went black and I got a big red notice. No signal. Could not see anything. No speedometer no nothing after while a black screen went away and I got the regular screen back but it had all of the fault lights lit up. This happened periodically through the whole trip. In addition, the heads up display worked periodically only. And I could not use the cruise control as it kept telling me that it couldn't see my eyes. Although I did not have any glasses on at the time. I feel very unsafe with this car. It is at the dealership waiting for new wiring harness but as I see in social media this has happened to many other people. I think this is something you should know about.

2025 Hyundai Tucson sel convenience the car is equipped with faw forward attention warning system which is supposed to give a warning if the driver's focus is diverted from looking at the road. The problem is that while driving in what Hyundai calls hda (highway driving assist) which activates when the car is placed in adaptive cruise control (cruise control that keeps the vehicle at a set speed and distance from the cars ahead) and lane driving assist (driving assist to keep the vehicle centered in the lane) the car issues far too many false warnings telling the driver to "keep your eyes on the road". While in hda, the car monitors the driver's eyes and head position using a driver facing camera, part of the faw (forward attention warning system) or ddms (direct driver monitoring system) to assure the driver is focused on the road ahead. However, in the 2025 Hyundai, this system is so flawed that the car is practically undrivable in the hda mode with cruise control and lane driving assist engaged issuing too many false warnings, that the driver is not focusing on the road. The multiple warnings, in some cases every few seconds, is extremely distracting taking the driver's attention away from safely controlling the vehicle. The system which is intended to make the vehicle safer is instead such a distraction it makes the car unsafe due to the constant false warnings requiring driver attention to address them and away from safely operating the vehicle.

What component failed: forward attention warning / highway drive assist safety at risk: Hyundai's driver attention camera fails for me when I wear prescription eyeglasses while it is sunny out. Without prescription glasses, I cannot drive safely. Further, repeated driver attention alerts cause the car to autonomously stop, which is a safety risk problem reproduced: yes, Hyundai says this is operating as designed and I should get other eyewear (despite me needing them to drive) vehicle inspected: yes, by Hyundai service technician warning messages: "keep your eyes on the road", even when I am fully paying attention to the road.

I wear prescription glasses which transitions to darker shades, and while driving 2025 Hyundai Tucson hybrid ltd in driver assist mode (Smart cruise control) the vehicle is warns me with some message to stop the car and then deactivates the cruise control. . . Because of this it is becoming very problematic to use the driver assist features. Is there a way that the sensors that keeps an eye on my eyes when use the glasses be disabled but still I can use the Smart cruise control? I do not see this eye attention feature is of any use and is not helping people like me who wear prescription glasses which transitions to darker shades during day time.

I have raised issues with Hyundai with the first week of driving this Tucson hybrid. I have ask repeatedly to get the collision control turned off, the dealership said they could not turn it off with permission form Hyundai. Hyundai so called customer service escalated it now several times and not a single call back. I was assigned a specialist named lejo ,national consumer affairs, Hyundai motor America 714-627-9707. Because he is no longer able to help he told me it was escalated and got yet to this day to hear back from anyone. This vehicle has tried to kill us several times and the dealership and Hyundai have been made aware of what it has done. Slamming on the breaks and warning collision, pulling you almost in the ditch because it was raining? this has happen several times. The same thing when a cars turns the corner and is leaving the main road and as I move to the passing lane the car said warning and actually pulled us back behind the car we were passing and then hit the brakes and almost rear ended to car we were trying to avoid. This system can be manually be turned off by me but comes on each time the vehicle is started again. I am only asking that Hyundai permanently shut it off for the duration of my lease. Because of the safety issues with this 2025 Tucson hybrid I feel it necessary to inform the public and hhtsa. If Hyundai does not turn it off then they need to be prepared to buy back the lease, Hyundai is well aware of the problems as they have issued a TSB 25-gi-017h apparently you only are to drive away from the sun ,avoid rain,fog and snow? VIN # km8jbdd19su369214.

Cannot use the cruise control when wearing my sunglasses. Sunglasses protect the eyes from sun damage and this is highly recommended by my ophthalmologist. This makes the protection provided by the eye data unsafe as I have to chose either cruise or sun protection. Makes no safety sense.

On June 30, 2025, I was driving at about 55 mph with the Smart cruise on. A message appeared on the left side of the dash (in the left circular screen) that said “conditions for Smart cruise have not been met”. And the cruise turned off, then a second message appeared that said the engine has been put on idle. At that time I tried to use the gas pedal and got no response. Fortunately I was near a parking lot on my left and had enough momentum to pull in and park. I turned the Tucson off and restarted it and was able to continue to drive. I took the Tucson to the dealer and they tried to duplicate the issue, but were unable to do so. Then the ran a diagnostic, but said it indicated everything came back as normal. I purchased this Tucson limited hybrid on 1/23/2025 so the fact that the dealer couldn’t duplicate the incident didn’t surprise me. I believe that this was caused by a software problem even though the diagnosis by the dealer indicated everything was normal and in range. However, I believe that their equipment and/or their technical expertise was insufficient to identify the problem. You can imagine the danger if this occurs on an interstate or other highway where speeds are as high as 65 to 70 & higher by some drivers.

The forward attention warning system uses a camera on the steering column. It goes off constantly while wearing my required glasses. Hyundai nor the dealership will turn off the sensor. There are over 10,000 complaints for this issue and Hyundai will not correct the issue. The system will automatically adjust the speed and brake in the vehicle without the driver. I almost had a wreck yesterday when it shut the car down when the camera couldn’t see my eyeballs while wearing my glasses. Something needs to be done. I’m thinking of filing a lawsuit against Hyundai as a class action. Please advise if you have any suggestions. Thank you.

What component or system failed or malfunctioned, and is it available for inspection upon request? > while driving, the following systems fail and become inoperable sporadically: blind-spot safety system, tire pressure monitoring system, Smart cruise control system, lane following assist system, speed limit warning system, shifter system malfunction, infotainment system, hvac controls and turn signals. How was your safety or the safety of others put at risk? > I lose access to all safety systems and am unable to see anything on my dashboard while every single light flashes on the dash. Being unable to utilize my turn signals is dangerous because I must restart the vehicle for the issue to be resolved. Has the problem been reproduced or confirmed by a dealer or independent service center? > the problems were confirmed - but not reproduced by the Hyundai certified service center. They stated that they can see logs of the issues and were unable to diagnose the specific failures without the warning lights being actively present. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? > yes. It was sold to me as a certified pre-owned vehicle directly from a Hyundai dealership. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? > the warnings and failures appeared at 64,752 miles, which is less than 5,000 miles after the warranty coverage ended. I purchased the vehicle with 64,300 miles. The issues began less than 500 miles after purchase.

This vehicle has a notification "consider taking a break. " it activates every 20-30 minutes, even though I am a safe driver. It is distraction to driving, whith is less safe than the warning itself. I would like for you to contact Hyundai to find a way to disconnect this, for they say it can not be disabled. Diosabling can be done on older models, but not newer models. I have a 2025 Hyundai tuscon. It is a sfety hazard.

I have been having a number of things happen; 1- my car will lurch forward at times when I release the brake and hit the gas pedal. 2- the forward collision warning keeps coming on. 3- my heating and oil cooler hoses leaking as well as metal lines, all started to leak at the same time.

This vehicle has a camera facing the driver mounted on the steering column. If it can't see your eyes clearly it starts sending warnings about pulling over and resting, it shuts down cruise control, doesn't allow it function. Shutting down cruise control at interstate speeds without the driver expecting it could cause an accident or worse. This camera not functioning correctly for one of the 16 possible reasons listed in the manual is unacceptable. It should have an off switch or be removed completely. . .

The driver attention warning continues to go off shutting the cruise control off. This happens continuously and is a safety issue when driving in traffic and the vehicle suddenly decelerates. This causes traffic behind you to almost reared you because the vehicle decelerates so quickly. Hyundai suggests to move seat, not to wear glasses and other options that in themselves are additional safety concerns as seat positioning and glasses are needed for driving. So far my car has had the sensor located on top of the steering column shimmed up, and wiring harness replaced all to no satisfactory conclusion. Hyundai is aware of the issue, but has no solution to the issue. I’ve been in a loaner for almost 2 months while they string me along looking for a solution. Something needs to be done to fix this safety concern.

While driving in a 70 mph speed zone on [xxx] , I tried to engage the cruise control but it would not activate. After repeated tries I finally was able to get a response and the cruise control engaged but only for about 15 seconds then warnings saying I was not paying attention to the road flashed on the windshield monitor along with check engine light, followed by vehicle slowing. I turned off the cruise control and was able to resume control of the car. This happened twice within 15 minutes so I gave up trying to use the cruise control. I wear progressive prescription transition eyeglasses which turn gray upon contact with sunlight. It was a bright sunny day when this event took place. I bought the car Dec 4 2024. When I contacted the dealers service department, they said the nearest appointment was not until February and they might need the car for up to two weeks to determine the problem. I went online and found that other owners had been complaining about this since April claiming that sunglasses were a problem for the radar camera used in this system. One driver put black tape over the camera to stop the problem. One driver switched sun glass makes and was able to use the system. Another driver adjusted the steering column to solve the problem, but all of these are work arounds for a defective design. You can locate these other complaints by searching "adaptive cruise control problems of Hyundai Tucson" complaints go beyond April 2023.

There is a sensor on the steering column that turns off the cruise control if it can’t see your eyes. This happens abruptly and slows the car down. It will cause a rear end collision if not taken care of! has been to the dealer 5 times. Is available for more inspection. There is a sensor on the steering column that turns off the cruise control if it can’t see your eyes. This happens abruptly and slows the car down. It will cause a rear end collision if not taken care of! I have more documentation from the dealers but I don’t have room to upload. Yes dealers have reproduce the issue. Manufacture has been notified and had us take to dealers. Warning message on dash but no time to react.

I could not find an exact category check above, but this does sort of relate to cruise control. The driver attention warning cannot be disabled even though there is an option to disable it. Turning it off has no affect. This is a warning that basically tells you to keep your eyes on the road. Sunglasses and regular eyeglasses can often cause it to create a warning. The system will then turn off cruise control if it's being used. According to several owners, this is common on newer model Hyundais and Hyundai either chooses not to or simply cannot fix this. My wife has notified Hyundai and is awaiting a response.

The Smart cruise control (scc) on my 2025 Hyundai Tucson limited hev cuts off whenever I wear prescription sunglasses. The driver attention warning comes on within seconds when the in-cabin camera mounted on the steering wheel is unable to see my eyes, the scc cuts off, and the vehicle suddenly starts breaking. This puts me and anyone behind me at risk. Both the dealership and Hyundai motor company have been unresponsive or unwilling to fix this widely known issue which is well documented in multiple owners' online chat groups. The dealership told me the manufacturer is responsible for fixing the problem.

The 2025 Hyundai Tucson's adaptive cruise control (acc) system does not operate properly due to either a design flaw or a flawed implementation of the design. Hyundai's integration of forward attention warning (faw) with the acc prohibits the driver from using acc while wearing sunglasses. If one is driving the vehicle with acc engaged and puts on sunglasses, the faw flashes a warning on the dashboard and disengages the acc. In order to engage cruise control the driver must interact with the onboard video display system to switch from acc to "dumb cruise". Obviously the driver's attention is distracted while manipulating the selection of cruise control. The driver is also forced to compromise driving safety because they are forced to choose between wearing sunglasses and being able to use acc. Use of acc enhances safety especially when driving into the sun or in low visibility situations. The incompatibility of acc with sunglasses wear then compromises safety. To make matters worse the faw options screen provides erroneous information. It indicates that the driver can turn off faw, but turning it off does not in fact turn it off. Turning it off stops the faw warnings only until the driver turns on and engages acc at which time acc apparently forces faw back on and active. I took the problem to my local Hyundai dealer who confirmed the problem and indicated they could not repair the problem. Since I am considering a georgia lemon law claim, I asked whether I needed to bring the car back since the lemon law gives the dealer/manufacturer 3 tries to fix the problem. The dealer indicated that would be a waste of time because Hyundai will not support/allow the issue to be corrected. The dealer indicated this is a known issue. An internet search also confirms that Hyundai's faw + acc integration is flawed. Additionally it is not clear whether other enhanced vehicle safety systems such as automatic emergency braking are compromised by the wearing of sunglasses?.

Forward attention warning is a system with a camera on the top of the steering wheel column that is supposed to check if the driver is looking forward when assisted driving like lane keeping is active during cruise control. This system does not work with sunglasses. Wearing sunglasses to drive on a sunny day is a normal activity. If this system can not see your eyes then it assumes you are not looking forward and will try to shut off driver assistance like lane keeping and then goes another step with a threat to shut down the car no matter where the car is or how fast the car is going. I was going 70 down a highway and I get the forward attention warning and before I can do anything to convince the system I was looking ahead I got the warning that car was about to be shut down. This is the second day in a new car so I was lucky to think to turn off cruise control, but it was a scary incident that could have gone bad quickly. This is not a safe system and and needs to be able to be turned off without disabling the driver assistance features.

Two incidents while driving on the highway. 1. Emergency braking activated on its own. No cars around me. It was a rural area. The red emergency braking activated light showed up and my car braked but resumed driving. This is a new car with less than 4k miles on it. 2. The hands free assist and cruise control were activated. My care swerved to the right abruptly. My hands were on the wheel and I was able to correct this but this is very concerning as my daughter drives this car on mountain roads when she is going to college. I have read online reports when others driving the same make, model and year vehicle.

Car throttle, ac, cruise control, car transmission and gears not correct, radio turns off completely and messes up carplay. Also no updated radio. Scary car is still new with all of these issues.

Forward radar sensor pass side lower grill/bumper area. 1st told a sensor recall but after 3 hrs and then seeing the vehicle in the shop with the entire front bumper clip removed the sensor was out of its driver side socket and 1 side flopping around which may have caused a small dimple from the inside to pop out on the 6x5 cover that is the entire lower rubber/plastic black bumper/grill. Told the vehicle was hit, yet no visible damage to bumpers or painted surface can be found by their 2 dealerships and their 1 body shop, + 2 mangers, and 1 independent collision shop. 1 manager drove the vehicle 10/11 and stated after "is operating as it should". Warnings have come on again since then refueling at additional 77 mile and then at 92 miles 10/14. Hartford ins has been notified and pending I hope an inspection. Vehicle purchased 1st March 2024, 1st warning at 5336mies currently at 5421 miles. They triggered the service engine light and stated via onboard computer it was an issue with a lower front driver side radiator something that may have been bumped while taking off the front clip, which they chipped and area and left a bit of gap at the fender connection. Other than the small dimple on the plastic from what I believe the sensor had been bouncing against, there is no damage. A safelight windshield company stated there is a notice/recall on the "auto headlight sensor on dash" but they do not cal them, only the optic sensor top center of windshield. But per the manual that top sensor plus lower radar can control the forward crash, cruise setup and auto braking. Need some help since my firm works with all auto/tire mfg and conducts dot tire testing for USA and worldwide independent firms/gov's.

On a recent road trip to utah on 2 occasions the cars automatic breaking system assumed a vehicle in the left lane and ahead of me by a few car lengths, had crossed its lane causing my car to brake abruptly at highway speed. The first time this occurred I was so surprised I don't remember what the other car was doing. However, the 2nd time I do remember the circumstances. I was driving east out of amarillo and noticed a double semi trailer weaving a bit in the right lane. I was one lane to the left. There was a strong south wind and it appeared the truck was having trouble staying in his lane. My lane was clear of traffic for at least 1/2 mile. The highway was was straight. The truck was 100 yards or so in front of me when my car suddenly braked very hard I'm guessing reducing my speed by 20 or more mph. I'm glad there was no one on my tail! there was no danger at anytime and there was no need for such hard braking. A week later, a third incident of the same typed occurred. I was driving on [xxx] heading north in moderate traffic at highway speed and the car again broke heavily when there was no danger. Again, a black BMW was to the right of me- this time only 3-4 car lengths ahead. I was watching the that car as I would be overtaking it soon, when it moved close to the dashed lane marking but I don't believe it crossed it, causing my car to brake hard again! again, I was lucky there was no one behind me, but this could have caused an accident! again, there was no danger-- at least until the car hit the brakes too hard. The car collected a lot of bugs on the road trip and I had not washed the car prior to the 3rd incident. The car has been washed and something similar has not occurred again- but I have not needed to drive it on a highway since. Part 2 of this problem is the car's spyware called bluelink collects data on driving habits and reports / sells that info to others. In none of these 3 situations did I do anything to cause the car to beh information redacted pursuant to the freedom of informat.

We bought Tucson 2024 sel from stafford Hyundaijanuary 1, 2024. We were happy new vehicle owner and yourself. Sales told us it will be good for at least few years without any problem after four months and 22 days the vehicle started not running call chantilly service they connected me with the online service and they suggested us to call roadside assistant and jumpstart. While we talk with them jumpstart vehicle rolled down the driveway the door was open bumped by the carport wall. Luckily the vehicle stop didn’t damage anything behind other houses or anything. The door was damaged. We don’t want this vehicle anymore. We want return or replace. It’s a brand new vehicle and it’s a life safety issue and I have a special son. , bad battery after four months and rolled down the driveway, I want to mention the service manager instance of empathy he told us nothing last forever have a bad battery after four months and roll down the vehicle is very normal. He mentioned checked the role down, but alfred from service said only repair happened bad battery and also manager said he did inform Hyundai motor corporation. I spoke with the case manager after I spoke with service manager andand he said he never spoke with safford service and no one return his callsl. He tried to call multiple times. Gap communication, and false information is giving to us and we purchased this vehicle from here we do not want this vehicle we want return or replacement, otherwise someone has to sign a bond and saying this is safe to drive.

Our 2023 Hyundai Tucson hybrid developed an issue with the forward radar. At speed, the car produces a warning ding and then a warning message is displayed stating, "critical forward safety functions are limited. Radar blocked. " if the adaptive cruise control is engaged at the time of the warning, it immediately disengages, forcing the driver to quickly respond. If there is a vehicle in the adjacent lane to the right, the automatic braking may at times activate. It happens rain or shine, in good or inclement weather. We have cleaned the areas of the sensors without effect. One dealership has evaluated the vehicle twice and a second dealership once but we have been informed that there was no defect identified. I believe this issue to be a serious safety defect.

Driving interstate right lane cruise control set at 73 mph. Car in front of me proceeded to leave lane to the left in order to pass 18 wheeler in front of it. Noticed my car felt different at that time and looked at dashboard to see cruise control now set to 110 mph and speed almost 90 mph. Documented with photo. Disabled cruise with breaking. Shared this on Tucson forums reddit and Hyundai forums with confirmation that this has and is happening.

While driving on the highway going up a 6% grade incline, the car stopped accelerating and car engine stalled out. There were no previous warning signs or indications of engine problems prior to this incident. There was no light that alarmed any defect to the car. The car had always driven smoothly. I maintained proper maintenance and regular oil changes. The car only had 65,000 miles on it. The safety of my passengers were at risk due to stalling out on the highway, luckily there was no harm to myself or others on the road. The dealership confirmed that the engine will need to be replaced. The engine has not been inspected by the manufacture. Unfortunately, due to a rebuilt title was declined warranty coverage. The title was rebuilt due to hail damage, no crash or flood damage.

When the vehicle was started the srs light remained illuminated and when driving the vehicle over 40 mph the abs, traction control, collision avoidance, and start-stop lights on the instrument cluster come on and remained on. The adaptive cruise control, nor the button for the start-stop deactivation work. The vehicle has just over 500 miles on the vehicle and is less than a week old.

Vehicle randomly keeps accelerating past the set speed when cruise control is set. Problem was first noticed in March. Have a video of the cruise set at 69 mph and the vehicle continued to accelerate to 87 mph before I disengaged it. Vehicle has been to two different Hyundai dealers for the issue but were unable to duplicate or find the issue. One moth ago were on a road trip and the cruise would accelerate to 8-10mph over the set speed on the cruise control especially after cresting a hill ,then the adaptive cruise control would brake hard when approaching another vehicle. 0.
