Warnings problems of the 2014 Subaru Outback

I purchased this vehicle in may 2024 within 2 months of purchase the eyesight function malfunctioned. I took it back to the dealership where I purchased it and they attempted to diagnose it at cost of parts and I ended up paying a few hundred dollars for that repair. That didn’t work and they offered to attempt something else but this was just guessing. Then a few months down the line I receive a post card in the mail for a ‘warranty extension’ on the exact issue I am having. I take it to the Subaru dealership once and they had me return a second time saying they couldn’t diagnose it at that time because the lights that appear on and off weren’t appearing for them. Returning a second time they said they were able to diagnose the issue but the warranty only covers 75%. The remaining 25% that’s left to me comes to $1098. 34. The issue I have with this is being it is a safety concern. The features eyesight provides are to be additional safety features. The biggest one being the cruise control that has gone out on me while using it. Going high velocity down the freeway using it and it shuts off completely, luckily I it hasn’t caused an accident and there hasn’t been anyone behind me when it happens and no one to close in front of me but this has happened on multiple occasions to myself, my boyfriend and most recently a friend when we went out of town when I didnt think to inform her of it. We no longer use the cruise control being it is scary and a risk to our safety. I have escalated to Subaru of America who says that it is a warranty extension to care for their customers but the representative I spoke with denied it being a known issue. He says the warranty expired in 2016 for my vehicle but Subaru extended it as to care for the customers. With that in mind I do not think I’m the only one with this issue and concern or else why would they put this extension out if they’re no just trying to be compensated and avoid a recall for the issue.
