This only affect 05-06 legacy gt owners. The up-pipe for the subaru legacy gt in these given years have a catalytic converter in there and after a certain mileage, the debris of the catalytic converter breaking down would shoot back into the turbocharger. That would cause the turbo failure and stall the vehicle unexpectedly. The catalytic converter in the up-pipe does not have any indication of % of wear and most non-car enthusiasts would not know what the issue is caused by except for an expensive turbo replacement and up-pipe replacements. Most of the owners of these issues turn over to catless up-pipe but that would cause the check engine light coming on and overboosting or the engine run rich, further damaging the engine. This can be pretty dangerous if a person is on a road trip and having a long drive as it directly impact the drivability of the vehicle. Subaru has recognize the issue and therefore 07+ turbo models all have a catless up-pipe with the ecu tuned to that specification. I believe it is not fair for 05-06 legacy gt owners to have to suffer from such a critical issue without some sort of compensation or recall. Thank you for your time

I experienced two issues with the electronic throttle position sensor in my 2006 subaru legacy. The first time I was traveling at approx. 35 MPH and the RPM's began increasing rapidly. I was in traffic and unable to pull off to the side safely when the engine completely stalled. I sat there thinking that the motor was going to blow up if I attempted to start it again. I called my mechanic and he thought that it could be the throttle position sensor, as he has replaced many of them on subarus. I was able to start the car and move off to the side of the road to make sure that it was not going to do it again. The car was then taken to the mechanic where he cleaned the sensor and said if I have a problem again then I should replace it. Fast forward 4 months later and I experienced the same problem on a busy street where the car lost power and completely shut down after rpms skyrocketed and I was left with no control. Upon start up, the check engine light came on, obviously triggering a code that says the car is a death trap with a really poorly designed throttle. I plan to have the part replaced immediately, but this could be a serious safety issue for someone not in a position to move to the side of the road, as it just happens randomly with no warning signs.

Complaint pertains to a 2006 subaru legacy 4dr sedan. In 2009, we experienced several instances of where the vehicle shut off completely when the driver stopped at a light or stop sign. Could not re-start for a minute or two. Multiple trips to the dealer over 9 months until finally diagnosed as a defective crankshaft sensor. Replaced by dealer (n/c). My reason for the report is that this could of occurred (but did not) on a major highway when a driver would come to a stop due to traffic. A stall on a major highway could put the driver in an unsafe situation.
