yes, If you lock them yourself, then they wont lock as they already are, like I said this is a normal function and they should lock automatically around 15mph for safety. Most all new cars do this these days, it was a feature they added as people in the bigger cities were getting robbed when at a stop light. Sounds like they are operating as designed. However, they should not unlock themselfs when driving, if this occurs there is a short.
