NHTSA cited nine "failure reports," seven of which matched Bloomberg's findings. "Entrapment in a vehicle is particularly concerning in emergency situations, such as when children are entrapped in a hot vehicle," the agency said. Bloomberg writes that owners told regulators they sometimes broke windows to reach trapped passengers. "No one should have to resort to breaking the windows to get into their own car when their child or pet is trapped inside because the door handles fail to work," said Rosemary Shahan, president of Consumers for Auto Reliability and Safety. Tesla has not commented on the probe. Chair Robyn Denholm, asked last week about Bloomberg's investigation, said only that the board "takes seriously" any safety incidents. Safety advocates argue that Tesla's manual release latches are difficult to find in emergencies.
