(KGO) -- "Walter was just a straight up, caring guy," Shawn Price told the ABC7 News I-Team.

Friends and family are mourning the death of Apple engineer Walter Huang after he crashed in his Tesla in Mountain View Friday.

Tonight, the ABC7 I-Team has word of a major development in the investigation. His family says Huang complained about the Tesla's auto-pilot "before" the accident. Dan Noyes has an exclusive report.

Walter Huang's family tells Dan Noyes he took his Tesla to the dealer, complaining that -- on multiple occasions -- the auto-pilot veered toward that same barrier -- the one his Model X hit on Friday when he died.

ABC7 News Photographer Dean Smith captured exclusive video today of investigators from the CHP's Multidisciplinary Accident Investigation Team and National Transportation Safety Board at a San Mateo tow yard, inspecting the wreckage of the Tesla Model X involved in that fatal crash on southbound 101 Friday. We spotted them taking a control module out of the vehicle, tucking it into an evidence bag.

The NTSB told Dan Noyes from their Washington headquarters, they recovered both the restraint control module and infotainment module today.

NTSB Spokesman Christopher O'Neil said, "We're going to work with CHP and Tesla to download the information from those modules and then see what data is available to us that might give insights into what was going on during the accident sequence."

We're learning much more about the victim -- 38-year-old Walter Huang had a wife and two kids, lived in Foster City, worked for 13 years as a programmer at Electronic Arts. This past November, he got a job as an Apple engineer and bought his new Tesla, posting a picture on his Facebook page.

He showed the SUV to his friends and former co-workers; we spoke with two outside Electronic Arts today.

"He was proud," said Shawn Price. "He was showing the gull wings, I remember going, a little bit of jealousy, like well."
