The 2016s have it

I would think some hacker could make a lot of money if he figured out how to turn it on in the 2015's. I would think it is just a software switch that is turned off in the 2015's and on in the 2016's
....and assume a ton of liability.

While I agree that it is probably a pretty simple procedure to reprogram the system for automatic braking, you can rest assured that the first time that one of the "upgraded" 2015s fails to automatically brake and is involved in a collision that the lawyers will be involved in a heartbeat. The "hacker" that shared the fix will be in a world of hurt.

Can it be done?

I brought up this same topic a while ago and most posts were negative about how too much automation is spoiling the driving experience. Apparently many posters did not look upon the idea favorably. I enjoy driving also but after owning a Genesis with the feature and having it proved its usefulness I would have waited for the 2016 if I knew. I’m sure there must be a knowledgeable source in the system somewhere that could answer that question. I would like to know if it can be done . It appears all the hardware is in place.

The smart cruise is intended for use on highway travel to maintain a safe distance between you and the vehicles in the front. It should not be viewed as a means of emergency braking and shouldn't be used around town regardless.

And yes, it will slow you down and quickly. The cruise has to be set as well as the smart cruise.

I'm not understanding what "software" is going to do. Smart Cruise is a radar system. If it comes with the car it should work.

BTW, that radar system costs about $4,200 so don't run into anything depending on it to stop you. Ouch!

In your personal opinion. Try it in city traffic you might like it. Software controls everything in your car.

You make it sound like "The cruise has to be set as well as the smart cruise." is two selections - not true turn on the cruise and you have smart cruise.

I too use the smart cc in traffic. That's what it was designed for, stop and start. My biggest problem with it is the delay in moving after pushing "resume". It's alright if no ones behind me. I've been just accelerating with the gas pedal until the cc catches up so the traffic behind me doesn't start blowing the horn.

Designed for use in stop & go traffic? Really? I was always taught that CC was designed for highway use in dry road conditions. The Sonata Owner's manual section on the Smart Cruise Control (page 5-54) seems to agree with me.

•Use the Smart Cruise Control
System only when traveling
on open highways
in good
weather.
• Do not use the Smart Cruise
Control when it may not be
safe to keep the vehicle at a
constant speed:
- Driving in heavy or varying
speed traffic.

- On slippery (rainy, icy or
snow covered) roads.
- Hilly or winding roads.
- Very windy areas.
Not that I typically take the Owners Manual as gospel, but in this case I agree with it.

I'm not going to belabor this subject but personally I believe it to be quite dangerous to use it in heavy traffic. And it will work. But there is a catch. While it will slow the car down to match the speed of the vehicle in front, one would have to assume that it cannot fail, plus your foot is not going to be in the right position to move from the accelerator to the brake in the event it does not perform exactly as you would and it may be too abrupt. I just wouldn't do it personally.

If you crash into another vehicle be prepared to have deep pockets for as I have said that smart cruise radar unit costs $4,200 to replace plus any other damages. In reality a relatively minor accident might result in having to total the car. I'd follow the owner's manual explicitly without deviation.

I don't own a Sonata currently but an Azera. I am assuming the radar unit is probably the same although I haven't looked into that to be certain. What I would be interested in hearing about is whether the Sonata has the forward collision warning system and if it works.

I have the lane departure feature (works from a camera beneath the rear view mirror) which works fine but I've yet to hear the collision warning system go off. Any thoughts on this would be appreciated. This is a bone of contention with Hyundai which I am attempting to resolve peacefully and without court action. It's right on the window sticker. Not sure what the Sonata has.

The Genesis has it plus a rather nifty lane departure feature which "steers" the vehicle back onto the center of the road. There is a slight vibration along with the alarm which the Azera does not. It only signals the alarm but not assist. The Equus has had the smart cruise for at least three years that I know of.

In summary I would strongly urge reconsideration of using the smart cruise in traffic but one can do what they will. It does not affect me but I thought I would express my thoughts to help those who might have had similar concerns.

One other thing. The smart cruise will not pick up a stopped vehicle or pedestrian. The vehicle in front must be moving. Something to think about.

Other SCC Systems are advertised for use in heavy traffic. They work the same... So whats the difference? This is just one step closer to autonomous driving IMO

Then why are you posting in the Sonata area on a thread with a question about the Sonata? >:D

What I would be interested in hearing about is whether the Sonata has the forward collision warning system and if it works.
It does and it works. Ive had it go off several times... Also, that is what this thread is all about. The 2015 Sonata just warns you of a collision threat. The 2016 will apply the breaks if you don't. The hardware in both cars (radar units, camera, etc.) is the same, and the SCC in the 2015 can bring the car to a full stop. So the capability is obviously a software difference in the two cars... Not a hardware difference. So OP is asking why can't we (2015 owners) get or pay to get the updated software.

I've yet to hear the collision warning system go off.
Must be a much better driver that me! :grin2:

This is a bone of contention with Hyundai which I am attempting to resolve peacefully and without court action.
Why on earth would you take Hyundai to court because you haven't almost been in a collision to set off the collision warning system?


In summary I would strongly urge reconsideration of using the smart cruise in traffic but one can do what they will.
Just read the description on BMW's website of their "Active Cruise Control with Stop&Go function" Its literally designed for it. Just like the system on our Sonata is.

One other thing. The smart cruise will not pick up a stopped vehicle or pedestrian. The vehicle in front must be moving. Something to think about.
You're right. It can't detect a pedestrian. However, It can detect if a vehicle is moving or not. Thats the "Stop and start functionality." It can literally bring the car to a full stop if the car in front stops moving...

I'm not sure. I think sensing pedestrians may use a combination of the camera that does the lane departure warning and the radar... Thats how I've seen other systems that can detect pedestrians implemented. I can't find a part blow out of the 2016 Sonata to compare part numbers. I really do believe its all in the software and that all of the hardware is identical... But then again, I could be wrong.

Seems pretty clear that there are a couple schools of thought regarding this issue and neither side is going to be swayed to agree with the other. My last comment on this is to relate a recent incident that occurred while driving my Sonata.

I was travelling on a two lane road and rounding a bend in the road. I was on the inside of the curve and the collision avoidance system picked up a vehicle travelling towards me in the opposite lane on the outside of the curve and sounded the collision avoidance warning. At no time was there any danger of a collision as both vehicles were travelling as they should be in their respective lanes. If the same system that activated the collision warning had applied the brakes to avoid what it interpreted as a pending accident, who knows what might have happened? Rear ended by a following car? Skidding into the path of the oncoming vehicle? Who knows?

My point being that the collision warning system is far from infallible and I wouldn't want to be relying on it to be doing my braking for me.

Anyone who relied on this systems to do their braking would be foolish. I see these as tools to help keep me from running into another vehicle or pedestrian. Look at the percentage of crashes caused by drivers taking there eyes off the road for any reason. Insurance studies have shown that rear end collisions dropped by 30 % on vehicles with AEB. Hopefully I will never need the AEB system but I like it being there just in case. Apparently I haven't driven on a road that caused the AEB to come on.

I agree with crisis. In the 9 months I've had my 2015 the Collision Warning tone has sounded about a dozen times. In only ONE of those instances was I anywhere near to a collision. I cringe at what would have happened in those other 11 times had my brakes been automatically activated.

Just read my owners manual. The Forward Warning (1st warning) is a warning chime only, plus it's user adjustable to fast, normal, or slow. The Collision Warning (2nd warning) is a chime plus some vehicle system intervention by the engine management system to help decelerate the vehicle. Emergency Braking (3rd warning) is an alarm and automatic emergency braking of the vehicle is applied in order to avoid a collision. The braking control is automatically deactivated when the driver sharply depresses the brake pedal or abruptly operates the steering wheel. The owners manual has 11 pages on the operation of the AEB.

I have the 2016 with the AEB. In the 4 month I've had it the alarm has gone off twice. Neither time was the brake applied as I was not to that trigger point. The first I had not responded quick enough to slowing traffic ahead of me. The second the traffic in my lane was stopping but I was accelerating to merge into a space in the next lane over. Both times I would count as legit. I'm just happy the brake did not trigger on the second instance.

First I’ll discuss my experience with my Genesis which has AEB. A lot has been said about the system not responding to pedestrians. The Genesis manual also states that it won’t pick up pedestrians. In a couple of articles written on the car engineers were questioned about this. Their response was that it was a legal issue because the car was not certified as such but indeed it could and had been tested. One day I was driving through a town on a street with a posted limit of 30 mph and parked cars on both sides. I was doing about 25 mph since I know it to be a heavily monitored street because of churches and schools. While passing some of the parked cars a stray dog walked out between parked cars it happened so fast there was no way I could have stopped the car in time but stop it did. I just sat there for a moment looking at my wife and she said “it worked”. You see till that time and since we’ve never actually seen the AEB initiate. I’ve seen the collision alarm come on sometimes depending on the situation but It’s never really stopped the car just given me ample warning for braking. Which clarifies the difference between warning and actual braking. If the option to upgrade my present 2015 Warning system to a real AEB ever became available I’d do it in heart beat. I really like my car but if I knew I would have waited.

I have the 2016 Sonata Hybrid Limited with the Ultimate package that includes the Smart Cruise feature with only forward collision warning. I later found out about the AEB feature, and that AEB is only available on the 2016 non-hybrid models.

I can't understand why Hyundai would omit this AEB safety feature on the 2016 hybrid models. In my opinion, Hyundai screwed up big time here.

I'm hoping Hyundai provides a software update along with a supplement to the Owner's Manual on the AEB operation.

I use my my adaptive cruse control all the time. It's nice on my highway commute. It will go from full speed (75-80mph) to a stop if traffic does so. It's amazing in stop and go! It's nice to just have to sit and steer and not go from breaking to gas back to breaking.

Since it does all this, I find it odd that when it detects a possible "collision", it just makes a sound and does not apply breaks. If it already has the system on board why not have that as a feature?

Just an FYI. I have a 2015 2.0 t with the Ultimate package.

I turn off the lane departure warning, its very annoying. Also the collision warning seems to be a little to sensitive in heavy traffic. Mine goes off every once in a while when someone in front of me is turning off the street I'm on. The car can be a good two car lengths ahead of me and it will go off.
