Wife was driving the car on the freeway and the power steering went out. We thought that a belt had broken or something. She was on her way to the mechanic when it seemed as though the car would not accelerate and was making a loud clunking noise in the engine bay, all of the gauges stopped working. The ABS, sport shift and e-brake lights on the dash all turned on each time she stopped. The car died just past an intersection and was pushed into the open area of a parking lot. Since it was hot she, my daughter and my dog all got out and went into the shade of some nearby trees. Within 5 minutes a bystander pointed out that there was a fire underneath the car and the fire department was called. They arrived within the next 10 minutes and the car was completely engulfed in flames. The fire chief said that it was a complete loss and that they have no idea what might have caused it.
Dt*: the contact stated while driving the vehicle was hit on the front passenger side, near the bumper and wheel. The other vehicle impacted the vehicle at 40 MPH. The airbags did not deploy and the engine did not shut off. The manufacturer determined due to the angle of impact the airbags should not deploy. The contact was wearing a seatbelt, but sustained whiplash. There was a police report taken at the scene. The vehicle was towed to the dealership.

Fuel & propulsion system all 27 →
While pressing the accelerator there was no response. The car continued at it's normal idle, but pressing on the gas gave no response. I was able to coast to a stop off the road and turn the car off and back on, which fixed the problem the first time. This has happened again two times as of today and it took several times turning the car off and back on to get use of the accelerator again. This seems like a safety issued, and of course a problem that could easily leave me and my kids stranded or injured in an accident if I were traveling at higher speeds when the problem occurs. I've read online that it seems to be a common problem with Subaru. The code that I received was p2138 (throttle position sensor).
Plastic fuel pump basket/assembly flange that mounts on top of fuel tank structurally deteriorates resulting in multiple cracks that allow fuel to leak out of tank below the rear passenger seat. We own two different 2005 Subaru Legacy models (one sedan, one station wagon) and upon inspection discovered that the fuel pump basket flange on both cars showed exactly the same structural defect. The fuel basket assembly is only available directly from Subaru of America and the repair involves substantial labor to change all parts over. This is clearly a structural or design issue and not a question of maintenance or random quality control.
