Lane DepartureUnknown Or Other

The lane assist failed by over correcting while I have my hands on the steering wheel. It over corrects to the center lane when you are driving with normal behavior. This can cause a collision if it were to over correct while a car was there, this is also easily reproducible in my car.

I have a 2021 Subaru Ascent that falls under an extended warranty regarding the windshield due to a faulty windshield. My windshield has cracked, reduce visibility, and does not allow the forward collision warning to work properly. Subaru recognizes the faulty windshield and refuses to remedy the issue. I question the safety and integrity of this windshield to protect from normal road debris strikes, allow normal visibility, and the integrity of the lamination of the from windshield in the event of a collision.

Lane Departure

Vehicle drifts on the highway and pulls hard to the left, which is a very concerning safety issue. I have already taken the vehicle to the dealer; they did a calibration of the eyesight. The problem still persists, especially when driving the vehicle on the highway. This has almost pulled me into traffic on a few occasions!

I am really concern about my family safety and the safety of others in the road.

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.

Lane Departure

It is actually the lane centering system. Even a gentle hand on the wheel, which is required, will gradually pull you to one side of the lane. When ever you lift your hand or when the car thinks you have gone to far one way or the other it will throw you into the other lane, into a car, motorcycle, semi, or even off a cliff. …

It is actually the lane centering system. Even a gentle hand on the wheel, which is required, will gradually pull you to one side of the lane. When ever you lift your hand or when the car thinks you have gone to far one way or the other it will throw you into the other lane, into a car, motorcycle, semi, or even off a cliff. This system is so dangerous I cant believe it hasnt been recalled. If using this you will get thrown one way or the other several times during most trips. Dealer states its normal and I got that in writing.

My mirror on my car has started melting. They told me it was a outside force, from a lighter. I told them it was electrical or something wrong from the inside of the mirror. There are forums recently posted up regarding this and Subaru has ignored them all claiming it is reflective light from the sun. That they can’t do anything about it. Others have replaced their mirrors 3 times now. This is a potential fire hazard and could be unsafe. They are not addressing this as it should be. https://www.thesubaruforums.com/threads/melting-side-view-mirror.12397/

The car constantly over-corrects when it tries to keep me centered in a lane on the highway. It always over-corrects to the left shoving me to the left into the adjoining lane, and potentially side swiping vehicles in the adjoining lane. It never over-corrects to the right. I reported this to the dealer and I was told that this …

The lane keeping assist pull abruptly into the other traffic lane when traveling on the highway for example when on a 4 lane road with two lane in the same direcstion and passing a semi truck the steering assist abruptly pulls the car into the truck's lane and requires immediate hard handed reaction to keep the car from hitting the truck. The lane assist on this subaru vehicle is more dangerous than it is helpful. Subaru is terribly un response to request for help although the car is less than 1-year old and has a mult-year extended warranty---subaru's customer service is the worst we've experienced. BTW my son's Honda Acura's lane assist is excellent!
