| Vehicle Controls Speed Control problems |
Went on a long trip over the last 2 weeks that involved >2000 miles of highway driving. Wanted to use the adaptive cruise control but couldn't because of frequent sudden braking for no apparent reason. The last time that it happened was on i84 with no cars in sight in either direction, no large signs in sight, and no changes in pavement color in sight. We were traveling at 80mph with adaptive cruise control engaged (self driving was not engaged) and the car suddenly braked to less than 50mph before I could intervene to regain speed control. We couldn't use adaptive cruise control for the rest of the trip because we decided that it was too dangerous.
