Torque converter problem: I went to bob baker subaru carlsbad, ca this 12:10pm, 06/04/18. I told the services guy that my engine shut off after step on brakes at low speed. I researched and downloaded the design problem notice from subaru, and he said the need to do more testing on my vehicle. I was waiting until 5pm and he finally told me that was it. I was represented the notice that came from subaru company. Why he was still hesitate not to fix immediately after I presented the notice. I believe that they had a lot of customers complaint before??

I put my foot on the brake at an intersection (came to a hard stop) after deceleration and the engine hesitated, then stalled/stopped completely. I must put the car in park and restart the engine to remedy the stall. This has occurred 4 times in the last week. In two situations, the vehicle behind me had started to accelerate, but my vehicle was not in motion because I must put the car in '(p)ark' to restart the car. This is a safety hazard because the car stops so abruptly.

The car experiences a 2-3 second intermittent hesitation followed by the car jetting forward. In addition, the vehicle has experienced occasional stalling. It has been taken to the dealership some 22 times for the same issue and upon recreating the problem I was told it is a 'function of the transmission.' the car is unsafe and has nearly resulted in several accidents. It appears that there is some electrical issue rather than the transmission however, the car tends to experience issues generally between 15-20mph, 30-35mph, and 55-60mph.

Subaru 2010 legacy 3.6 has a dealer- acknowledged severe hesitation in acceleration. The car fails to accelerate when the gas pedal is initially engaged, there is a prolonged hesitation and then the car lurches forward unpredictably. It's particularly severe in a slow rolling situation such as accelerating upon turning at an intersection. The car simple "can't get out of it's own way" in a timely, reliable and predictable fashion. Dealer was notified within the week of sale, acknowledged that subaru of america was aware of the problem and promised to do something about it. No remedy appears to be forthcoming (or even known) by subaru of america.
