3- CVT Transmission- Shifts from Park to Drive, and from Drive to Reverse are very slow to engage, which can be annoying when you accidentally pull out into traffic a little too far. 

5- Power- The 2.5l is great on fuel, but it is fairly gutless. I wouldn’t take this wagon to the racetrack and it sure lets me know it's working when driving up steep mountain passes. But hey,  you can't beat that gas mileage with today's gas prices!

6- Trailer Light Connection: Buried inside the car and you need a special harness to connect with and extend out your trunk for the connection.

7-Fragile Windshields: Subaru outbacks are notorious (at least recently) for having windshields that crack very easily. Mine was chipped by a rock on the highway in the first two weeks after buying it and the chip quickly spread into a long crack. I know windshields all are susceptible to cracking, but outbacks seem like they are more weak than most. 

Bottom Line: If you are looking for a highly capable car that can haul some groceries on Monday and a pile of camping gear on Friday, all while keeping you safe and getting around 30mpg- this is a great option. If you want a heavy-hauler or something that you can race around town in you may need to look elsewhere.
