In your search for a car to buy, you encounter a possible car of Brand X. A friend, at one point, had confided that she had had a bad experience with Brand X—it was a lemon

You remember what she said, but you do not focus on it much, and soon you are evaluating the car without thinking of it. What circumstance would likely increase your feelings of suspicion about the car you are considering?

While a friend telling me to be careful about a particular brand because of her personal experience with it is nice, I am much more likely to be suspicious of any Brand X car if I myself have had a bad experience with that brand of car.
