general problems of the 2017 Subaru Legacy

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.

When running on a highway and you press down on the accelerator hard to merge onto a highway or go around a vehicle to move out of the way of vehicles quickly coming up behind you, the engine takes over and speeds up on its own. It has occurred three times on a newly purchased used car and it will increase speed up to 100mph. You have to press intermittently on the brakes to pull over to the shoulder and turn off the car for five minutes for the car to reset. If you try to just break, you get a burning smell. I see two class action lawsuits on similar acceleration issues for 2015 to 2017 outback/legacy series.

When I go to park my 2017 Subaru Legacy, I put my car in park and the key will not turn. It gets stuck and the engine will not turn off. Consequently, I am not able to turn off my car and take my key out. The dealer told me to back up my car and thrust my gear shifter into park. Then I was able to turn the key off. However, the situation continues to happen every time that I drive the car. It is clearly an issue with the engine/car as this never happened prior. I was told that Subaru's frequently have defective solenoids that holds the key in when the car is running might be defective. I have not yet seen a recall.
