NHTSA Complaint #11528372 — 2023 SUBARU OUTBACK

While driving at a high rate of speed on a remote road, using cruise control, my vehicle suddenly braked/decelerated for no reason. Could have been the automatic emergency braking, adaptive cruise control, or forward collision warning. The first time it happened, a warning bell sounded, red lights flashed, and the vehicle decelerated VERY rapidly. It happened again about 6 weeks later, but the second time there was no audio or visual warning, the vehicle just decelerated rapidly. If there had been a vehicle behind my vehicle I might have been rear-ended because there was nothing on the road in front of me to warrant rapid deceleration. Also, on both occasions, the deceleration was swift enough to cause items in the vehicle to dislodge.
