2017 SUBARU LEGACY Suspension Problems

When i brought car in for an oil change. cam carrier leak, was reported to me that there was a cam carrier leak. When i look online there are countless reports of this. Seems like there could be something faulty with the engine. Subaru offered to cover the repair as a 1 time curtesy. But if there is an issue with the design of an engine then this should be looked at further. The rear brushings are also failing don't think this should happen so quickly, maybe faulty brushings. no warning lights.

Vehicle is difficult to control, especially when driving on uneven roads, or when it is windy. It takes a lot of effort to keep the car in one lane. The ride is rough, and you can hear and feel every little bump in the road. More than a rough ride, this will oftentimes throw my vehicle off path which feels like the car is not in my control momentarily. For instance, it will follow the direction of any cracks/grooves in the road, despite both my hands being on the wheel. This deviation requires immediate correction or risk collision. A passing vehicle moving at a high rate of speed will also push my car off track, which is obviously dangerous on the freeway.
