KT Analysis Question

Applied K.T. problem analysis to find the real problem of the following situation. Situation: Molly traded in her old car for a 1-year-old, high-end car that had a special keyless entry system. Everything about the car worked perfectly, with one exception: When Molly would park the car, sometimes she would come out to find its motor running. In each instance, she had turned the motor off and taken the key out before leaving the car. This problem most often occurred at the Starbucks on Washtenaw Avenue, a major thoroughfare, but seldom at the Starbucks on Liberty Street, which was a more secluded street. It also occurred a couple of times at Dunkin' Donuts on Stadium Street. Even though the problem mainly occurred on Washtenaw, she did not want to stop going there because she enjoyed chatting with the policemen who frequented that location. The Liberty Street Starbucks seemed to have only an occasional policeman stop by. The problem arose during visiting the midmorning hours but not over lunch or dinnertime
