I have been reporting problems with my transmission since 2012 to my regular dealership, star subaru when the car had just 23,472 miles on it. At this point, I believe that I have been wrongfully denied warranty coverage. Then again, in 2017, while still under warranty, I brought my outback to star subaru complaining that while driving slow, the car tends to 'jump' mid-drive, almost like someone rear ended you. The car at this point was at about 94,467 miles, under the 100,000 mile warranty limit. After numerous complaints I finally received a test drive with a subaru mechanic at star subaru in bayside, queens, ny. He concluded that it needed transmission parts, a torque converter/valve body. At that point I was set to have it replaced once the parts came in. Weeks went by and I heard nothing. I contacted subaru of america who was able to set me up with east hills subaru. The soa person was very helpful with the transition. They performed their own diagnostic, and the condition at the time would not replicate. Unfortunately, when this 'jump/slam' happens, it does spontaneously. We cannot make it happen, nor do we even know when it is going to happen. It was always very sporadic. Sometimes it would happen on the highway going 65, or sometimes less than 5mph. On a long trip back from vermont, there would be a large revving sound, and then it felt as if someone hit us from behind. Once again, I took the car to subaru, only to be told they simply couldn't 'replicate the problem', and therefore would not do anything to help us. On april 3rd 2019, I bring my car in again to east hill subaru. Check engine light on. They do recall. They also troubleshoot the check engine code, which now comes up clearly as p1710 torque converter turbine 2 speed signal circuit malfunction. Now it's not covered under warranty.the price tag is very high, almost $6,000!

The CVT transmission is defective and extremely dangerous. The vehicle will suddenly stall when decelerating quickly. There is high potential to cause an accident. The manufacturer knows of the issue but will wait for the defect to occur rather than fixing the transmission.

Upon parking in a routine parking spot in our apartment parking garage, I turned the corner and accelerated some, as I always did, to get to the parking spot to back in. As soon as I went to reverse it, the car accelerated fully on its own accord. I was able to press the break and stop the vehicle but since I was only about 10 feet from another car and the wall of the parking garage, I was not able to stop in time to avoid a collision. I hit the corner of the cement wall with the front left headlight portion of the vehicle.
