Two men have died after a self-driving Tesla crashed into a tree late Saturday in the Houston suburb of Spring.

Authorities told Houston's NBC affiliate KPRC that an investigation showed that no one was driving the electric 2019 Tesla Model S. One man was in the front passenger seat and the other was in the rear passenger seat.

The car was reportedly traveling at a high speed along a curve when it hit the tree at about 11:25 p.m. local time.

KPRC also reported that "firefighters say they had to call Tesla to figure out how to oust the blaze." Officials said that it took four hours and 23,000 gallons of water to extinguish the fire.

This is not the first incident of a crash involving Tesla's Autopilot service. Investigators are looking into a March crash outside Lansing, Michigan, where the driver of a Tesla Model Y was using Autopilot and struck a state trooper’s cruiser.

Tesla tells drivers to pay attention to the road and be prepared to take the steering wheel when using Autopilot.

Tesla has not released a statement about Saturday's accident.
