I have had trouble with the cruise control on my 2012 Hyundai Sonata Limited since I bought it last November. The dealership had engineers from Hyundai come in and help them out with the first problem, but now a new problem-- a really dangerous one- has come up.
When I hit cruise control going downhill at anywhere between 55 and 70 mph, the rate of speed increases as the hill gets steeper. This is a new issue for this car. I drove it with one of the service techs in the car with me and it did what I mentioned above. Then I had him drive it. Same deal. He claims that he used to install cruise controls into cars, and that this is normal. I have driven many other cars in my life, and never experienced this.
Is it possible that he is telling me the truth? I have one more appointment at this dealership. Hopefully the next tech will take me seriously and try to fix the problem, but I know how people talk, and I don’t have a good feeling about this.
So, I would like to know if anyone else has had this problem with a new-ish Hyundai or any other car. I would also appreciate ideas about what this guy is saying to me and how to proceed if this dealership hangs tight to the assertion that this is “normal”.
