Due to the growing epidemic of front lower control arm failures, Subaru announced a recall of 300,000 Impreza 2.5RS, 2.5TS, 2.5i, and WRX from model years 2002-2007 with steel front control arms. The STi is not affected by this recall. This includes the Saab 9-X wagons with steel front control arms. Additionally, Forresters with steel front control arms from 2003-2008 are part of this recall. Basically, if the vehicle was registered in or sold into one of 20 "rust belt" states, the dealer wants to see your car to look at the front control arms. Depending on the severity of the damage, the arms will either be coated with some sort of rust proofing or be replaced. The letters should be going out to owners in early November. As far as I've heard, you will have to wait until that time before being able to book cars in for repair.
Guys, if you get the letter or have one of the affected vehicles and live or have lived in a rust-belt state, take this one seriously and get the recall service performed. When it goes, you lose the ability to steer the car and, in some cases, the ability to brake (if the line is severed, which is likely). Think what'll happen if it lets lose while you're doing 75 on the freeway and happen to be pointed straight at bridge supports in an interchange.
