One problem related to assist has been reported for the 2021 Kia Motor Soul. The most recently reported issues are listed below.
Driving 75 mph speed limit on I-19 (4 lane divided) northbound near green valley az. Dry clear. Is new car with 400 miles on it and I was using the lane keeping assistance hands free. Clearly visible painted lane lines. Worked fine until lane markings diverged at slight curve and at off ramp. The car drove directly into/onto the "v" between right lane and off ramp until I manually steered back to traffic lane. No alarm or vibration sounded before I had to manually steer back to traffic lane.
