In August 2018, "The Washington Post" reported that all delivered cars came with defective wiring that had to be replaced. In addition, WMATA began playing the announcement "This is a 7000-series train" whenever the train doors opened. This was intended as a temporary measure to aid the disabled because the types of barriers that separated the 7000-series cars posed safety risks for the blind. The FTA ordered WMATA to fix the barriers before the end of 2018, but WMATA could not meet that deadline. However, the barriers began appearing on 7000-series railcars in October 2018.
