Your 2023 Subaru Ascent's EyeSight Driver Assist system is causing your vehicle to suddenly jerk into adjacent lanes without warning, particularly when semi-trucks are nearby. This has happened multiple times to both you and your husband, forcing you to take immediate corrective action to avoid collisions. The issue appears to be a malfunction in the lane-keeping or object-detection component of the EyeSight system that may require recalibration or software updates.

Your Subaru EyeSight safety system is turning off randomly while driving or parked, and won't restart even after you restart the vehicle — leaving you without this key safety feature. You might see an orange indicator light on your dashboard or a small red "i" light when this happens, but you won't get a warning before it fails. The system should only shut down in heavy rain, snow, or fog and restart automatically, but yours is also shutting down in sunlight and when there's windshield condensation. The fix will likely involve diagnosing the camera system or related sensors that control EyeSight, and possibly replacing or recalibrating them.
