One problem related to adaptive cruise control has been reported for the 2020 Audi Q7. The most recently reported issues are listed below. Please also check out the statistics and reliability analysis of the 2020 Audi Q7 based on all problems reported for the 2020 Q7.
When driving with the cruise control on, the vehicle automatically adjusts the speed to the speed limit. On occasion, when driving at freeway speeds, it will pick up the speed limit from a cross street (over or under pass). This happened on a recent trip with the vehicle set at the speed limit of 75, then suddenly and automatically braking because it detected a 45 mph cross street. With most traffic moving at 75 mph, this was extremely dangerous to suddenly brake for no apparent reason with people right behind us. We can no longer us our cruise control because of this. The Audi dealership could not replicate this issue. It only happened to us in a small number of circumstances, but was dangerous and frightening when it did. The automatic speed adjust also apparently cannot be turned off. The dealership did mentioned they were aware of another Audi vehicle they had seen with the same issue.
