“While driving my 2006 Subaru wrx sti the engine suddenly seized up on the highway. There was a loss of power to everything including the power steering and brakes. I had to perform emergency maneuvers and steer into the emergency lane on the highway. I had the car taken to Subaru, they refused to honor the power train warranty on it and wanted $1500 to even look at it. I think took the car into a private mechanical shop and they found the cause of the problem, the oil pick up line cracked in half. …”
NHTSA complaint #10232608, filed 2008-06, 40,000 miles“2006 Subaru sti driving home 20 MPH oil light flickered then stayed on for 20 seconds engine starved of oil, shut down. Had engine removed to find oil pick up tube the weld had failed causing no oil to motor, now motor is junk. Now I find out this is a common problem. Subaru of america has made a up dated tube,my question is why? A problem. I have had my car for 3 months now its 6,000 dollar repair, for a poor weld job on a 20 dollar part. The sales on these tubes are not going to reflect on how many have failed because who can afford 6,000 dollars every time it fails. …”
NHTSA complaint #10374842, filed 2011-01, 83,550 miles“Code p1410 secondary air injection system switching valve stuck open. This is a common error many 2006 and up Subaru Impreza wrx owners are having. The emissions system is prone to fail due to carbon buildup or moisture and rust contaminating valves, leading to repairs costing $700 to $1500. This failure is common even with low mileage. Note these codes are also associated with this failure: 06/07 wrx: p0410 p0411 p0413 p0414 p0416 p0417 p0418 p2431 p2432 p2433 p2440 p2441 p2442 p2443 p2444 07 sti: p0410 p0411 p0413 p0414 p0418 p2431 p2432 p2433 p2441 p2444.”

NHTSA complaint #10256090, filed 2009-01, 36,550 miles“The contact owns a 2006 Subaru Impreza. While driving at any speed, coasting, and shifting gears, the vehicle loses all wheel drive power. The failure causes the vehicle to shift into neutral. The failure was more apparent at high altitudes and on icy roads. While driving downhill, the vehicle jerks before it shifts into neutral. The contact took the vehicle to the dealer, but they could not duplicate the failure. However, they reprogrammed the ECM. A local mechanic stated that the vehicle's torque converter and transmission were working improperly and the engine was six degrees too high. …”
