DEARBORN, Mich. — U.S. auto safety regulators are investigating complaints that the doors on some Ford Escapes can come open while the SUVs are being driven.

The investigation by the National Highway Traffic Safety Administration covers 346,000 Escapes from the 2020 and 2021 model years.

The agency says in documents posted Tuesday on its website that it has 118 complaints that spot welds in a door assembly bracket can fail. Many reported a popping noise when they opened the door as a bracket begins to separate. The agency says continued use could dislodge the door, and it could fail to latch when closed.

Ford says it’s working with the agency to support the investigation.
