We were driving locally, and the car stopped abruptly for no reason. There was no one and nothing in front of it, no animal around, and no reason for the stop. Had there been someone behind us, we would have had a big problem. We called the salesperson at the dealership only to learn that he had moved to Germany. We were told that another representative would return my call in about six minutes. No one called. A week later, we were on the highway and, also for no reason, the car slowed abruptly, and then resumed its speed. It happened a third time on a local street. We called the dealer and alerted the corporate headquarters but they did not respond. They do not seem to care.
