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

While driving, the check engine light comes on and there is no power to the gas pedal. The car is unable to accelerate or maintain speed and the driver needs to avoid potential collisions by pulling over on the road or freeway.

While driving at any speeds, lose acceleration and need to coast and pull over. Just before shutting off engine, rpms jump to 3-4,000 when in park. Need to turn off engine for at least 30 seconds before being able to turn car back on with check engine light on and cruise light flashing, but have acceleration again. After driving for around 100 miles, check engine and cruise light turn off, but randomly incident can happen again. Had a diagnostic check, confirming throttle position sensor when check engine light was on.

Two occurrences so far on wednesday march 23 and tuesday april 5. Vehicle suddenly displays check engine light and the cruise control light flashes and vehicle drops into "limp mode." problem is apparently due to wear on the potentiometers in the drive-by-wire system. This wear causes different readings which makes the motor think something is wrong with the pedal and cuts the vehicle speed to roughly 5 MPH. First occurrence driving along at posted speed of 45 MPH. Second instance trying to leave from a stoplight, got into the intersection and the vehicle speed dropped, was barely able to get vehicle out of intersection. (cel code p 2138 - throttle position sensor)

One morning after starting my car I noticed the check engine light was on. As I decided to drive the car down to a local mechanic, I noticed that I had no acceleration power. The car was on, engine was running, but whenever I pushed the gas pedal nothing happened. The car would idle high and coast when put in drive or reverse, but would not accelerate as I pushed the pedal. There have been numerous counts of this happening to people across the country. Luckily I wasn't on the freeway when this happened.

While driving the check engine light suddenly came on and the gas pedal stopped being responsive. Luckily I was able to get to the side of the road and put the vehicle in park. When in park the engine revved to about 2.5k RPM and stayed there. I shut off the vehicle and restarted it and it stayed at that level. After several more tries it eventually started up and ran fine. The check engine light code is p2138 for the throttle position sensor.
