Police driving a Tesla the California patrol car had to abandon the search for a suspect when the electric car ran out of charge.
But the agents say the drama was the result of human error instead of a problem with the car.
The Tesla Model S is built in Fremont, California, and the local police department is using an example as a test.
Fremont Police Officer Jesse Hartman made headlines in the United States when his Tesla Model S showed a low battery warning on the service line.
On the radio messages released after the chase, Hartman tells the dispatchers: "I just realized I'm about to run out of six miles of battery … I have to find a charging station for Tesla so I can restore it."
Another officer in a conventional car took over the pursuit.
The police said Tesla's battery is flat because an agent from a previous shift forgot to connect it.
California of News on mercury, interrupting the story, claimed that Tesla is part of a process to see if electric cars can replace petrol and diesel vehicles on government fleets.
The publication quoted the Fremont police captain, Sean Washington, that the car behaves impressively and that "we are easily able to cope with an 11-hour shift with battery power".
Victoria Police has become the first Australian jurisdiction to field a highway patrol by putting a Tesla Model X work in June.
Inspector Stuart Bailey, highway patrol officer, told the Herald Sun that Tesla is "the fastest car in our fleet".
"I can see our entire electric fleet in the future," said inspector Bailey.
"It's coming and it's coming quickly.
"We are putting ourselves in an excellent position, so when it comes we have done all the research and development and are ready for the transition without compromising our capabilities".
