(NEWSnet/AP) — The U.S. Justice Department has requested documents from Tesla related to its Autopilot and “Full Self-Driving” features, according to a regulatory filing.

The Austin, Texas, electric vehicle maker cautioned that if the government decided to pursue an enforcement action, it could possibly have a material adverse impact on its business. 

Tesla is already facing multiple investigations by the National Highway Traffic Safety Administration for problems with its two driver-assist systems, Autopilot and “Full Self-Driving.”

The systems have been under investigation by NHTSA since June of 2016 after multiple deaths using the autopilot feature.
