2021 Subaru Legacy Driver Assist & ADAS Problems

The car's AEB system keeps mistaking steam from the street (such as sewer covers or construction sites) for a physical object and will activate. It has stopped my car in the middle of the street two days ago (5/31/22) and I was almost rear-ended by the car behind me. The warning system will also engage for no reason in most city driving conditions when there is no danger. It mistakes merging with cars with an imminent crash. I do not trust the system and now disable it whenever I drive as it is more likely to cause an accident than to prevent one. This has been a problem since I purchased the car. I contacted the dealer on 5/31/22 but have not heard back.

The contact owns a 2021 Subaru Legacy. The contact stated that while his wife was reversing out of the garage, the rearview camera froze. There was no warning light illuminated. The contact’s wife was able to reset the rearview camera with the assistance of his daughter who looked up the information on the internet. The vehicle was taken to the dealer who diagnosed that no issues were found. The contact stated that the failure reoccurred several times while driving. The vehicle was taken to the dealer who completed a 504-software update; however, the failure reoccurred twice while the contact was driving from the dealer to his residence. The vehicle was taken back to the dealer who informed the contact that they could not duplicate the failure. The manufacturer was notified of the failure and informed the contact that they would either ship a head unit to the dealer for the repair of the vehicle or they would buy back the vehicle. The manufacturer followed up with the contact and informed him that they would not assist as the dealer was unable to duplicate the failure. The contact referenced NHTSA Campaign Number: 20V766000 (Back Over Prevention) however, the vehicle year was not included. The vehicle was not repaired. The failure mileage was approximately 5,000.
