An Apple engineer who died when his Tesla Model X hit a concrete barrier on a Silicon Valley freeway had complained before his death that the SUV's Autopilot system would malfunction in the area where the crash happened, according to official documents.
The complaints were detailed in documents released by the National Transportation Safety Board (NTSB) in the US.
The NTSB is investigating the March 2018 crash that killed engineer Walter Huang.
Huang told his wife that Autopilot had previously veered his SUV towards the same barrier on US 101.
The Huang family is suing Tesla and California's Department of Transportation for allegedly failing to maintain the highway.
