Problem: Intermittent problem with advanced smart cruise control and autonomous braking on a new 2017 Kia Sorento with less than 500 miles. What happened: When using the advanced smart control feature, as explained to me by the dealer, the manual, and Kia videos, the car will stop autonomously when approaching a car at a stop light. My Kia stops autonomously most of the time, but not all of the time. On three occasions, while driving with smart cruise control, on a straight road on a clear day, my Kia slowed down but did not stop, causing me to take emergency evasive action at the last second. After two occurrences, I contacted the dealer and asked to simply have the system checked. The dealer stated that they do not handle safety concerns, and directed me to call Kia, which I did more than a month ago. The Kia rep tried to tell me that the vehicle cannot stop while using advanced smart cruise control, despite their tv ads, instructional videos, and my own experiences which says the car does indeed stop in the smart cruise control mode. The Kia rep said someone from Kia would follow-up, but that never happened. So, after waiting more than a month, I am filing this report to see if others are experiencing problems with this critical safety technology. Otherwise, the Kia operates normally and is a very nice SUV. I just want my Sorento checked out before an accident occurs.
