criticalVEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE
CrashFiled: Aug 2024

While preparing to park in a parking lot, your vehicle suddenly accelerated and increased speed on its own. Your car struck a parked vehicle, then traveled across the lot over curbs, grass, and landscaping before hitting a building at high speed and causing partial structural damage. The automatic emergency braking system did not activate to prevent the collision. The cause remains unclear — it's unknown whether the accelerator was pressed unintentionally or if there was a system malfunction.

mediumVEHICLE SPEED CONTROL,FORWARD COLLISION AVOIDANCE,LANE DEPARTURE
Filed: Nov 2022

Adaptive Cruise Control, Automatic Emergency Braking, Forward Collision Warning, Lane Departure Warning, Lane Keeping Assistance, Eye Sight, RAB, some ! Symbol, and check engine light are all on and not working. You know everything that makes a Subaru. This is not the first or even second time. We are on the fourth instance of this happening. We live 2+ hrs away from the closest dealers. The first few times it occurred, we called to make a appointment. Each time was always a few weeks out and the issue would clear a day or two before. This last time has been going on for 6 weeks. We both work full time and have a very sick kid so making a appointment is hard. This last time I asked if I can drop in just for a scan due to being in town for an appointment. Was met with we are backed up with way to many repairs. Also it would not be fair to any other people. It is most likely your gas cap. I have made sure the cap is tight as it can get every time from the first time it occurred. So all safety features on the Subaru Ascent just stop working if the cap is not tight. Not only is this a major safety issue their QA is asleep at the wheel. Known issue, just check the forums.
