| Description of the problem | Https://youtu. Be/z4thv5a3lrk dynamic cruise control that stops and starts in bumper-to-bumper traffic is what sold me on this car. Lamentably, i did not know hyundai excludes aeb from hybrid ltd ultras. As the video shows, frantic beeping from the forward collision warning system was not accompanied by any braking at all. I slammed on them too late. I was in dcc mode when the warning sounded. Dcc can gradually slow from freeway speed to a stop and resume, but fcw apparently cancels dcc's braking! This must be no more than a difference in software between gas-only and hybrid ltd ultras because all sensing and control hardware are identical. Hyundai's response to my inquiries are just repetitious confirmations of what i already discovered the hard and expensive way. |
