I took my car in to get an alignment. The alignment was done properly, but the mechanic said he believes there is a problem with my torque sensor. When you step on the gas (for example at highway speeds) there is a significant pull to the left, and when you let off the gas the car goes back to the right. This phenomena does not happen at lower speeds on city streets. The mechanic said this excessive steering torque should be automatically corrected by the electric steering but it is not.
There are no error lights on the dashboard.
I am thinking of switching the front and rear driver side tires to see if the problem goes away (so that the two rear tires will be matched).
I told my mechanic this and he said he already tried this and it did not work. He thinks it is definitely a torque sensor/software issue and that I need to take it to Subaru before my warranty is up (that is a whole other issue. I have not hit 36k miles but have passed 3 years. I called one dealer who said ECU is not covered by the 5 year powertrain warranty but based on some Googling I think he was BSing me).
Any thoughts on this issue? Am I going about this the right way?
Thanks everyone for your thoughts. I wasn't sure what "technical issue" subforum this belongs in so I am posting in the general section for now.

You need two tires the same on the rear end or it will send the LSD into fits under certain condition. It is simple as that.
The electric steering does not compensate for anything. It is a simple assist.
Get a new mechanic since if he is blaming the ECU I am not convinced he knows how a LSD even works.
