2017 Subaru Outback drivetrain & axles problems

The gear shift does not engage fully in park when the car is stopped. This is an intermittent problem. If it is not engaged fully when the engine is off, the key cannot be removed and the gear shift can slide from park to reverse and neutral without pressing the gear shift button. It is necessary to restart the car sometimes two or three times in order for park to fully engage. Twice when the car was idling in park it did not engage fully and slid into reverse. The second time caused an accident but no injuries.

Since purchase on 2/19/17 from parker subaru cda, complaint of shaking front end, wandering on highway and freeway from side to side in a dangerous manner, from complete loss of steering in snow, slush and gravel as of 2/28/17. I have been very specific about the incidence. Going in my driveway at least 8 inccidents; in snow or slush conditions, in depts on only a couple inches or less in the winter of 2017.
