Service brakes

6 reports1 crash
“Under Subaru campaign WQK47, which supersedes an earlier campaign, 05-09 Legacy/Outback and other models are known to undergo accelerated brake line corrosion due to sub-par materials and design. Subaru of America's "fix" for this issue is to inspect the lines: if the lines are compromised, they replace them. If the lines are corroded but not yet compromised, the lines are coated with an anti-corrosion wax. This wax washes off the car and is ineffective. Subaru performed this recall work insufficiently on my vehicle, failing to identify the severity of the corrosion. They coated the lines, called it "fixed", and the brake lines later ruptured under normal driving conditions. This caused a highway near-miss at speed that could have impacted everyone on the road. Multiple Subaru dealerships in Connecticut have refused to re-inspect and repair the vehicle under the recall campaign, despite it being a known critical safety concern, and despite knowledge that the original parts and anti-corrosion application are sub-par. They insist that because the ineffective recall campaign was already "completed", they bear no further responsibility for the design compromises…”

“2009 Subaru Legacy 2.5I Parasitic Drain If vehicle is not driven every 2-4 days in winter or every 6-8 days when is warmer it will need a jump start. I looked for a recall but there isn't one for the year of my car or for the Fourth Generation 2005-2009 series. I took it to the dealer 4 times and they said there was nothing wrong the first two times. On the 3rd time they said it was my problem was that the battery was old and to prove them wrong I got one of their Subaru brand/label batteries and the same problem kept happening. I took it to one more mechanic with the same results. I keep seeing this articles on blogs online about Subaru's from multiple years and series having Parasitic Drain issues. I do have the receipts pack in boxes if need it.”

Visibility/wiper

“I WAS DRIVING MY 2009 SUBARU LEGACY SEDAN ON A RURAL HIGHWAY ON MY USUAL DAILY COMMUTE TO WORK. IT WAS DECEMBER 18, 2019 IN MONTANA, SO COLD, BUT NOT UNUSUALLY COLD, AND IT WAS SUNNY . I WAS DRIVING FOR ABOUT 50 MINUTES, AND WAS PROBABLY GOING AROUND 65-70MPH, WHEN I HEARD A LOUD NOISE ABOVE ME LIKE AN EXPLOSION. I LOOKED UP AND SAW AN OBLONG, SOMEWHAT RECTANGULAR, HOLE IN MY SUNROOF THAT WAS PROBABLY AROUND 8-9 INCHES LONG AND PROBABLY ABOUT 4 INCHES WIDE AT ITS WIDEST. THE REST OF THE SUNROOF WAS ALSO SHATTERED, THOUGH STILL INTACT. LOOKING AT THE SUNROOF FROM OUTSIDE, HOWEVER, THE SHATTERING WAS LESS EVIDENT. I IMMEDIATELY LOOKED AHEAD OF ME TO SEE WHETHER THERE WAS A TRUCK OR SOMETHING FROM WHICH SOMETHING COULD HAVE FLOWN OFF AND HIT MY SUNROOF. THERE WAS A PASSENGER CAR THAT WAS MAYBE AROUND 100 FEET AHEAD OF ME, AND THEN, AHEAD OF THAT CAR, THERE WAS A LOGGING TRUCK (CARRYING TREE LOGS), THAT WAS PROBABLY AT LEAST AN 1/8 MILE AHEAD OF ME. I DID NOT SEE ANYTHING FLY TOWARDS THE CAR BEFORE THE SUNROOF SHATTERED. THERE WAS LITTLE GLASS IN THE CAR, AND I PULLED OVER AND COULD FIND NO EVIDENCE OF ANY FOREIGN OBJECT INSIDE THE CAR. I EXITED THE CAR AND LOOKED…”
