My Tucson Limited is 3 months old and we took it on the freeway for the first time.
As we pass vehicles and when it is directly beside the Forward collision warning beeps, it applies the brakes momentarily and displays a warning. This a scary thing at 70 mph. Does this almost everytime so we tense up as we pass, dangerous is an understatement. Is the forward radar in the bumper sensors or in the wind shield. I duct taped over the right front and right sensors. I need to get back on the freeway and pass a vehicle.
I really don't want to let the dealer touch it, I just want the false warnings to stop.
Has anyone had this or know where the system get its signal?
Thanks

You can turn it off in the settings. But I leave mine on and I've never had this. It sounds like something is faulty or misaligned.

Strongly suggest you read the user manual and become acquainted with the new car. And then if you still do not understand how it works, when, and how to change the settings you should indeed let the dealer help you and have them go on a test drive too.

 

[my1sthyundaihev]

Yeah I know. Don't duct tape those sensors, as other system may depend on it as well to work properly.

If any issues, bring it to the dealer attention, turn off the FCA for the time being.

Read the manual if you are unfamiliar to the system.

It took me a while to get used to the new car systems these days as my previous one never have these safety technologies

It could be the car is telling you that you are not driving safely. For example , if you are changing lanes to pass, you will get a beep if you don't signal first. That is the system reading your vehicle crossing a lane line. If you get too close to the vehicle in front of you before you pass, you will also get a beep or an application of the brakes if you have it set to do so. You also have to be aware that if you pass someone while using the smart cruise control, your vehicle may accelerate automatically as you pass. Again, every time you cross a lane without signaling first you will get a warning. To deactivate the system I believe you long press the lane keep assist button on your steering wheel. I also believe it reactivates every time you restart.

I understand the vehicle. I read the manual twice. I tried turning the system off but it still gives false warning. There are 3 possible settings, off , warning only and intervention. I get intervention no matter what is selected. I tried it again yesterday with bumper sensor covered and it still trys to stop the vehicle. The radar signal must come from the windshield sensor. It may need calibrated.
And mungo544 I know theses systems and I fly jets for a living so don't insult me with not understanding. Tacky.

 

[mungo544]

Sorry you took it the wrong way. A lot of people here don't understand how these cars work. I'm not a mind reader, if you fly jets, know all about the systems, and are so much smarter than everybody else, why don't you fix it yourself instead of asking us peons for advice. By the way, trying to fix it with duck tape is tacky, no pun intended.

 

[Gr8ful]

Let's not throw insults, I just posted to see if any others had the same issues. I don't know more than anyone else but I can read. These new Tucsons seem to have many electronic issues, more than any of the last 65 new cars I have purchased.
I have belong to many car forums and I think that much can be learned from fellow owners. This one is not a car enthusiast forum and most here bought their Hyundai for normal ground transportation so I dont expect much in the way of technical advice.
This vehicle has a problem and I hate to have the dealer touch it as there is not much knowledge base in the shops now days. No code, no fix. I am trying to isolate the problem before I take to them. Or maybe just trade it. Not sure with all these other folks having failures.

If your car is defective that's one thing, but still the answer is going to a Dealer. But your assertion this car has many electronic issues I do not see born out in the forums or certainly in my daily use. In most of the cases it turns out the person did not understand how that particular thing works. That applies to me and locking the car with touching the door handle, reading posts here I now understand how to do it correctly - and it's not an electronic problem. Of course that does not mean there are no problems.

What you described when you hear beeps etc sounds to me what Mungo555 said, it thinks you are not driving safely, coming too close to the lines and or the car to the side of you, and not your guess of the front warning system where you are trying to tape it over. These features work and work well overall.

You could have a sensor unplugged somewhere that may cause conflicted data processing.
I only have this issue when I back out of my driveway going north and there is a vehicle in the opposite lane. No way I would back into the bus but it hits my brakes anyways. If your lane keeping assist works then it’s not the camera on your windshield. I have never had this happen on the highway though and I think you should have the dealer look at it.

 

[Gr8ful]

The sensor is plug in and fuctioning or I would get warnings. I removed the FWD Radar fuse and there were multiple warnings on the instruction panel. Replaced it.
OK

With Adaptive Cruise on or off, when passing a slower car, on their left side and my right, and when mid way through the pass with vehicle next mine (side mirror to side mirror )the warning bells go on , warnings on dash saying "Forward collision alert" in red and the brakes are momentarily applied. If cruise is on it also disconnects. The system is detecting something in front of my vehicle that not there. If I move way out to the left it sometime doesn't set off the warnings.

I wasn't sure which sensor was used for the Fwd collision System so thats why I taped over the right front sensor with duct tape. It gave the false warning again today so it must be the sensor/camera in the upper part the windshield. It will still activate the warnings and the brakes even with system turn totally off in the setup.
Plus if you depower( shutoff) the vehicle the system defaults to "on" again.
The Tuscon is really a nice car, comfortable, and seems well put together. I hate to have to replace it. I have KIA Stinger GT2 it has been flawless for over 2 years and 14k miles so I know they make good vehicles.
My wife doesn't want to drive it cause it scares her so much. I told just don't try and pass any cars.
Sad.

I have read here that whenever they replace a windshield, the sensors mounted to it need to be recalibrated. It might be worth a try to at least allow the dealer to get his hands on your car for that.

It is not clear from anywhere in all exchanges above ( unless I missed it) , if at any point, you actually turned OFF FSA ( under "Setup"- "Vehicle" - "Driver Assistance" - "Forward Safety" - and set it to "OFF")?
See image below

 

[Gr8ful]

Mungo,I think you might have it. I will research that. Thanks.
Gene yes I talk of turning the system off.

 

[Z Man!]

Did you ever "duct tape" any of the jets you flew?😁. I'm kidding. Couldn't help it. But curious why you would choose taping over sensors rather than letting a QUALIFIED TECHNICIAN who uses advanced computer systems to check it out. Seems to me, tape would only exacerbate your problem and cause more problems if indeed your system is malfunctioning, which is entirely possible. I do know when cruise is set for the one car length space, mine seems to brake when I'm not that close. At least that's how it feels to me. The Land Keep Assist, as others have said, can be aggressive if you don't signal before attempting to change lanes. I do hope you get your issue resolved and highly recommend a Hyundai dealership over duct tape. Good luck.

 

[Captain Pete]

I think what most people are saying is that nobody else is have erroneous collision warnings when cars are passing on the highway. Therefore I would also suspect a defect in your car that I would want Hyundai to fix it. The only time that I have seen the collision warning go off is when I am behind another car that is slowing down because they are turning off the road. If I step on the gas, assuming that they will soon be out of my lane, I sometimes get the collision warning. I think it is pretty reasonable that I get it then.

 

[Gr8ful]

Never duct tape a jet but we do use what's called "speed tape". A very strong shiny silver metal tape. Used on places on the fuselage where maybe panel is delaminated or to make area smooth. It's not a permanent fix.

 

[Gr8ful]

Capt Pete

My FCA works as it should. When the system senses a closure rate to an frontal object higher than the programed software allows it initiates the alerts and /or assists. Mine functions properly during this driving situation, But I'm get the same alerts/assists when passing a vehicle that's in the lane to my right.
I have not tried passing on the right.

Since I'm new and absolutely can not figure out how to add a question to this web site I've chosen to reply to this - first one to come up. Sorry the topic is not related. I have no idea how to get started here. And all this is to simply state I wonder the percentage of new owners of the Tucson who find it so and unimaginably complicated to understand the two manuals that, like me, they have just given up as I have? Then, I come to the Tucson forum and it is even more complicated and upsetting..... how to even enter a subject. THIS IS MY LAST POST. The irony is, that I'm a retired SOFTWARE ANALYST who did the job someone else did to create the manuals!!! How atrocious they are written. Too bad, really, that I have not been able to enjoy my new Tucson (Oct. 2021 purchase) because EVERYTHING IS UNBERABLY DIFFICULT TO GET A GRASP OF. On top of that, the settings I've entered revert OFTEN by themselves It's so miserable. My previous Sonata was a dream. Wish I had it back. This 4 cylinders gets the exact same gasileagey 2008 8 cylinders Sonata did and it drove smoother. My Tucson hops all over the road and THAT is unsettling.
