An investigation is underway to determine whether the Tesla Model X involved in a crash this month on the Pennsylvania Turnpike had its autopilot system activated.

The National Highway Traffic Safety Administration said in a statement that it was "collecting information" from police, Tesla and the driver to find out "whether automated functions were in use at the time" of the July 1 rollover accident in Bedford County in south-central Pennsylvania.

The probe comes shortly after the disclosure of the first U.S. death involving a car in self-driving mode. The Tesla Model S driver, a Pennsylvania native, was killed in a Florida crash in May.

The Pennsylvania Turnpike crash, first reported by the Detroit Free Press, left a well-known Michigan art dealer injured.

Police told the newspaper that driver Albert Scaglione reported activating the autopilot feature. Tesla, however, said the company had no evidence that could show whether the automated system was in use.

"Tesla received a message from the car on July 1st indicating a crash event, but logs were never transmitted. We have no data at this point to indicate that Autopilot was engaged or not engaged," the company said in a statement. "This is consistent with the nature of the damage reported in the press, which can cause the antenna to fail."

Scaglione and a passenger, his son-in-law, both survived the crash. A West Chester man's vehicle was also hit by debris from the Tesla, but was unharmed, according to the Free Press.

Scaglione told the New York Times on Wednesday that he had just been released from the hospital but wouldn't discuss the crash further.
