It’s just not right....I’ve driven hundreds of cars and never had one do this. I could understand if it was on hills and downshifting but it happens in every drive mode and on flats and corners. Better yet I wish Kia would own up to it and try to fix it. They won’t even attempt anything....I think they don’t know where to start.Sorry you have a cruise control that isn't smooth enough. Some people are more sensitive to these sorts of things. Some are driven wild by less than perfectly smooth; some are just as crazy but it takes more to make them feel that way.
This has come up every so often over the months. It isn't an "all or nothing" proposition. The jerkiness isn't constant, or as noticeable, or it gets better over time, or the driver just adapts to it and literally moves on. Etc. Form what I read, it does seem that a problem cruise control can smooth out after a while. So there is that hope.
I think you're right. Most vehicles don't exhibit this. But those that do are responding to a complex of factors, all electrical interfaces; where to start? You can't just yank out a cruise control and slap another one in: that would fix some, or a few, or none. It isn't an answer. Hopefully yours will settle down and you'll get used to it and the combination will work for you. I'd hate to think that a balky cruise control is a deal breaker. But lesser things have been and are deal breakers.
There is always going to be a "perfect storm"" set of conditions that cause the AI to screw it up. A year and a half ago, around here, a woman was on her cellphone (looking for alternate routes!?), while her Tesla "drove itself". She had been doing this for TWO YEARS, before the "perfect storm" of conditions caught her. On a highway that has a 60 MPH limit (which she had the cruise control set at), up ahead was an intersection with a red light. The car in front of her, that the "Auto Pilot" was keeping distance between by reducing speed, suddenly disappeared: no doubt the driver dodged quickly into the next lane over to take advantage of a shorter waiting lineup of vehicles. The Tesla, sensing open space now, increased speed back up to cruise: only to crash at 60 MPH (or a little less, the driver was just putting her foot on the brake pedal) into the rear of a fire truck. Had the sensors on the Tesla detected the stopped vehicle ahead, no doubt emergency braking would have been applied: but there wasn't enough time between following the vehicle in front, as they approached the stop light, and coming within sensor range of the stopped traffic. Something needed adjusting: imho, Tesla, et al., do not appreciate the nuances of altering driving conditions enough. "Auto Pilot"! Heh?
Do you have (or are you supposed to have) adaptive cruise control? I'm not quite sure if that's what the title of the thread is implying or not.
What does your dealer's service dept. say about this? You for sure need to document this malfunction with Kia. "Almost always" is just NOT good enough . . . when that one time you don't catch this in time, you will need documentation of the problem when you sue Kia.
I agree. I’ve seen this exact problem too many times myself. I reckon when I enable the cruise control with no cars in front, then it keeps going without detecting cars in front. When I enable it with other cars close in front, then it behaves normally and breaks in time.
I have just taken delivery of a new Stinger GT (in Australia) and am having the same issues. I've never experienced this with any Cruise Control previously. It's jerky; it changes down three gears as soon as it detects a car in front of me. Or it fails to slow down quickly enough. I notice that in "User Settings" you can change the sensitivity of the adaptive CC ('fast' / 'normal' / 'slow'). The manual doesn't really explain what this does, but mine was set to 'fast'. I've changed it to 'normal and hope this makes a difference. We'll see.
GT does not have it
it gets more even noticeable when you have an aftermarket exhaust and you can hear the revs go rrrrrrrrRrrrrrrrrRrrrrrrrRrrrrrrrRrrrrrr. You like that representation?
