NHTSA Complaint #11439325 — 2020 SUBARU OUTBACK

Purchased the vehicle new and from the beginning the passenger side blind spot detection has been inconsistent in alerting for vehicles in or approaching the blind spot. Had it checked when new and on 11/2/21 and the dealer reported it was operating according to specifications and no fault codes were shown. The dealer did not test drive the car. In a recent test of about 100 miles, about 20% of the time the BSD FAILED TO EITHER DETECT, or detected too late, a vehicle that was being passed or one approaching from behind on the passenger side. Remarkably it seems to fail more often when passing a semi. It caused a near miss at night when it was difficult to see through the deeply tinted windows and when the BSD failed to recognize a vehicle squarely in the blind spot as I tried to merge into the right lane. An internet search found at least one post which matches the experiences I have had. The driver's side BSD works fine.
