NHTSA Complaint #11461740 — 2022 POLESTAR POLESTAR 2

On 12/26/2021, I merged onto the I-5 South highway to Irvine, CA, and engaged Pilot Assist. The “speedometer dial” icon turned yellow (as expected), but the “car in front” and “hand hold wheel” icons remained grayed out. I believe this indicated 2 things: (1) the car was still looking for a lead car, and (2) the car was searching for clear lane markings. Everything appeared to be normal at this point as it does take some time to take over the steering. As I approach a slower moving lead car in front of me, I noticed that the car was still at my set speed (~75mph). I get closer and closer to the car in front and the car was not slowing down to match speed and maintain distance. I looked down and still see the same icons: “speedometer dial” icon is yellow (as expected), but the “car in front” and “hand hold wheel” icons were still grayed out. I believe the car didn’t see the car in front. Also, the steering function of the Pilot Assist never engaged. I tried to disengage and re-engage Pilot Assist several times but every time it worked like normal cruise control even when I’m very close to the car in front (~20 feet). I re-confirmed that I have always selected Adaptive Cruise Control in the center screen menu and it’s not a setting that I touched before this incident. I had to disengage Pilot Assist for the rest of the drive. When Pilot Assist is OFF, normally the Lane Keeping Aid icon in the driver display should turn white above 40mph when lane markings are clear. However, the LKA icon remained grayed out for the rest of the drive even when the lane markings are perfectly clear. After the stressful drive, we parked the car for 2 minutes, yet the issues still remained. We reached our destination and parked the car for 30 minutes, and the issues fixed themselves! Both Pilot Assist and LKA started working at the next drive.
