Jerky Cruise Control?

[WildBill]

I have not felt it recently. So I'm not sure if it's getting better, I'm getting used to it, or my local roads don't highlight the issue like the one road I noticed it on. Probably one of the later.

Just did a 600+ mile trip in the GT2. CC def. studders for no apparent reason.

I've owned my car for a week, and so far, the only complaint I have is the cruise control. Since I spend 75 percent of time behind the wheel driving up and down the highway, the surging is definitely noticeable, however not a deal breaker. I told my service advisor about it and he blamed it on the adaptive cruise, which I do not have. A very confused look then came over his face.. Wondering if anyone has created a ticket with Kia Motors? If enough of us make the complaint maybe they will eventually put out a TSB for it? I also wonder if they browse these boards

I have the same complaint/issue. I do have the SCC and haven't figured out how to disable adaptive cruise feature and see if that changes anything.

It isn't caused by adaptive cruise control.

Wow, I just ran across this thread. I have a Stinger GT (with only 2500 miles), and I noticed this cruise control issue just last week. I was driving a long stretch of open (flat) highway and there was no way to ignore it. Definitely felt the tug, lurching, whatever you want to call it. And this was constant, about every 5 seconds.

I don't use CC very often, but after reading all of the comments on this thread......I'm pretty pissed.

Did I miss anything on here about a resolution yet? I will take my car to the service department, but from the looks on here, not sure if KIA has acknowledged this ridiculous issue yet?

 

[Metalmania82]

No resolution yet it seems.

I had a lifted 2003 Xterra several years ago that would lurch/surge for the first couple minutes after initially engaging cruise control. It was almost as if was warming up and would work fine after reaching "operating temp."

This is a HUGE issue for me, as I use cruise all the time. Literally.

Every time I feel like I'm really leaning toward the Stinger, something like this comes up.

 

[WildBill]

Test it out for yourself.
I can feel it every once in a while but definitely not all the time.
I think some cars might do its more than others and I think some drivers are probably more sensitive to it than others.
I also think some of it comes down to the driving conditions such as what grade the road is at and how smooth the road is.

So definitely don't give up on the car due to this issue that may not be an issue at all.

Mine happens all the time no matter what speed, road condition, driving mode, etc.. My service department thus far has been no help and sort of just shrugged me off. I created a formal complaint with Kia (which you can do right online) on Aug. 26 and have a case number and would urge everyone else to do the same. The more of us they hear from, the more they will understand this is a real problem. After making the complaint it said I would be contacted via email and I have yet to receive one

I'll be sure to file a complaint, just to be safe. Sounds like the CC on our cars are acting up about the same level. It bothers me that some Stingers don't have this issue, and some do......to me, that indicates a clear problem somewhere along the production line.

Not to beat it to death, but some on the forum know I dumped an Infiniti M at quite a loss a few years ago because of this issue. In spite of the fact that cruise control has been around for decades, some mfr's can't seem to make it work right. And in spite of the fact Kia does a superb job with it on the Optima, somehow the problem is cropping up again in the Stinger!

When your car has this problem and let's say you're on a road trip, it will annoy hell out of you as it jerks and bucks mile after mile. Cruise control should be seamless and smooth and relaxed, with the system feathering throttle in and out as needed to maintain speed. When it goes crude and rough on small undulations in the road or down hills, feeling like there's some kind of slack in the drive train, it is unacceptable.

If the technology is out there to make cruise control operate smoothly, there is no excuse for choppy operation. Especially when you have other cars in your fleet that operate perfectly. And it's a big enough issue for me that I will not buy another car with the problem.

"Other cars in [the] fleet" includes the great majority of Stingers. Why some individual cars' cruise controls cause issues is the mystery question. Would a complete removal and replacement solve the individual car's problem? The Stinger does not have trouble with its cruise control: individual Stingers do. And so too do individual cars have brake issues, or badly running engines, or seized transmissions, or failing upholstery, or failing paint, or rattling moonroofs or hatches, etc. ad nauseam. The great majority of Stingers are virtually trouble free. None are perfect.

I have a feeling, like with all other faults in manufacturing, it may be affecting X amount of cars made between dates X and X. For example, the TSB they put out to fix the fast static gear shift logic was for vehicles manufactured between Sept. 29 and Feb. 7.

I have a feeling it effects all Stingers but some people just don't realize the car isn't supposed to behave this way.

There are also some folks who are very apologetic when it comes to any Stinger issues. These people will say "there's nothing wrong with the car, maybe your car was dropped on it's head as a youth, my car is perfect" (or similarly dismissive one-liners). This type of person is willing to overlook, excuse, and tolerate any issues with the car because they don't want to believe anything could possibly be wrong with their baby.

Do you have more info about the TSB you mention?

That may be true, but it's kinda like Viet Nam in the 60's ... you couldn't look at the locals and tell which one was carrying a grenade and which one liked you.

There's no way to tell if the issue exists in a Stinger or not, especially when a test drive might not reveal it. So they all get tarred with the same brush.

That's a bit harsh. Any make and model can provide examples of this or that individual car exhibiting "issues". Some individual cars are "Lemons" for no perceivable reason. That's why the lemon laws got created. When you get an unlucky car you need to get rid of it and not lose the whole thing; take the recompense money and hopefully avoid being unlucky next time. The Stinger is showing itself to be a very good first year model. Especially compared to many other brands' first year models. Kia has a success here. If someone hears of mushy brakes or floaty suspension or bad paint or surgey cruise control, etc., and doesn't know the reviews and drivers' experiences, they will come away with the false notion that this car sucks.

No, I'm not saying the car sucks. I'm merely saying that FOR ME, the specter of another car with the CC problem might well be the death blow.

I'm still looking and watching, and haven't totally ruled the car out at this point. I have some time on my Optima lease, so there's time to let this play out.

There will be MY19s that have troubled cruise control. How will you know that the car you pick doesn't have it? Any car? Any brand/model? Is the Stinger cruise control bad? Mine is as close to perfect as a machine can be. I've had cruise controls that did the surge or jerk thing but not continuously. My Stinger's cruise control is the best I've had. It works best uphill and on the flat, not so much downhill; sometimes it runs away downhill; the manual cautions about that. So did my other cruise controls allow speed above the setting. On mild to moderate grades (the kind of slopes that don't post grade warning signs) the cruise control works fine and the systems work together to keep the car at the setting speed. I've even had my paddle shifters overridden by the cruise control, i.e. it dominates and won't let me shift, dropping into 5th gear to hold the engine back. But it doesn't always do this; as I said, sometimes it runs away as per the manual caution. Not perfect, but very good most of the time.

I use cruise often and haven't noticed the issue. The only issue I've had is around the recognizing the car in front, but it's something I just have to get used to coming from a subaru's eyesight system.

I've got a 2015 Outback w/EyeSight and I was concerned that those brands that are newer to this (EyeSight has been around since 2011 I think?) would have some teething problems. I live in the San Francisco Bay Area and I can use adaptive cruise for hundreds of miles on I-5 to Los Angeles without ever a single problem with sudden braking (and if you know this part of I-5, you have to do **a lot** of lane changing unless you're willing to do 80+ mph to keep with the flow in the fast lane).

What I *do not like* about EyeSight is using it on a 35 mph road when the car in front of me signals to turn left and starts slowing down. EyeSight apparently calculates worst-case here because it will apply the brakes pretty hard assuming the preceding car is going to take a long time to complete its right turn. That, and EyeSight *will* let the speed drop by ~2 mph going up a hill before it kicks in again. Back to the positives though: EyeSight is brilliant at holding speed on downhill twisty mountain roads (probably in large part to how EyeSight modulates the CVT to use engine braking instead of the brake pedal). I doubt that a car without a CVT could offer such fine-grained control (don't get me wrong, I dislike the CVT in the Outback - I'm just saying it's a benefit in this circumstance).

Having gone on and on about this, my question to you is, how does the Stinger's dynamic cruise control perform compared to EyeSight?

Thanks
