What 2009 Subaru Legacy owners say
Air bags all 31 →
The airbag red light on the dashboard of our Subaru Legacy 2009 comes on intermittently. From reading personal accounts of other owners online, this appears to be a common problem with this model years 2005-2009 and has been commonly reported to be either a malfunctioning airbag control module or a faulty line or sensor in the diver's seat. Both of these result in a costly repair of approximately $2,000. Also happened to us, and another common complaint by other owners online with these models, is the passenger airbag light automatically turns on or off regardless of whether the passenger seat is occupied. Despite the abundance of personal accounts online by owners, Subaru has not acknowledged this problem and dealerships are asking owners to pay for this fix. …
I had the dealership install a Subaru remote starter for my 2009 Subaru Legacy. About a year later I started having issues with having the air bag light come on when I started the car and stay on (with remote starter, or the normal way). Sometimes it would re-set if I turned the car off and on again. But recently it just stays on and the indicator lights on the over head display (for the passenger air bag) does not light up at all . Not sure if the remote starter was the instigator (probably not), but Subaru had said that the issue is a faulty sensor and that I would have to pay to fix it. I believe this should last the life of the car since it is a safety matter for the air bag system, this should be a recall.

Engine & cooling
Car was kept up with timely, oil changes always taken care of. Warranty still on the car but dealership refusing to pay since car wasn't serviced there. At 90,000 miles on the four lane, out of nowhere, rod broke and I had catastrophic engine failure. The car was in motion and shut off, had to pull over on side of four lane going 55 MPH when car shut off, and car refused to start again. At no time was I given any forewarning about the engine having failure. Since the dealership is no help, I still owe 9,000 on the car so I am going to have to pay for a new engine at about 4,000 dollars.. Although the warranty is still good. I've read how multiple other people are having this same exact problem around 90,000 miles. Is there no recall? No investigation? Is there a defect in the engine? …
