The race car driver Andy Pilgrim has long been associated with GM’s most powerful offerings, driving C5 Corvettes for Chevy in the early aughts, later moving on to CTS-Vs for the Cadillac factory team. All of which is to say this isn’t his first rodeo, though it might be the first time OnStar flipped on mid-lap.

Pilgrim was driving a 2019 Corvette ZR1 at NCM Motorsports Park in Bowling Green, Kentucky, recently where, during the course of just over a lap three different OnStar representatives get on the phone with Pilgrim to see if he’s all right. Each time, he assures them that, yes, he’s fine, just on a racetrack.

Chevy couldn’t really figure out what happened, (emphasis mine):

Chevy engineers were unable to find a solution or offer a definitive explanation for the calls, but it seems reasonable to conclude that a particular combination of speed, g load, yaw angle, and longitudinal and lateral acceleration/deceleration rates can trick the system into believing the vehicle has been in a crash—or that its driver is auditioning for a seat with the factory-backed Corvette Racing team.

Pilgrim, this ZR1, and NCM are apparently just cursed, though cars registering enough G forces to trigger Onstar’s crash alert system has happened before, .

I emailed GM to see if they could shed any more light on the situation and will update this post if I hear back.
