Strange cruise control behavior
Bought a 2019 Cadenza a few months ago. The cruise control behavior is odd. It sets fine, and one second bump ups and downs with the switch works fine, resulting in 1 mph increases and decreases respectively. But when you have it set and hold the switch in the down position, to say, slow the car by 10 mph then release it, it doesn't reset at that speed. Pressing down again quickly to get it to set at the desired speed, nothing happens, the car continues to slow. Same in the up position in the reverse sense. If you hold it in the up position to increase speed by say, 10 mph, then release it the car keeps on gaining speed and does not stop when the switch is released. The only fix is to turn off the cruise control and start over. BTW, I don't have the smart cruise control.
Any idea for this behavior? Has anyone experienced this with their Cadenzas? Never had another car that this has happened with. Something in the ECU perhaps? Thanks for responses.
