1 Service Brakes problem

Failure Date: 08/01/2024

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 and sub-par materials that are the root cause of this issue. Additionally: under Subaru bulletin 12-197-16r the dashboard of 05-09 Subaru Legacy/outback models is known to become sticky and melt. While this might initially be considered a cosmetic issue, the melted surface is dramatically reflective. The hump over the gauge cluster melts first, causing a huge, intense sun glare reflection in the windscreen directly ahead of the driver. I own two 05-09 Subaru legacies; this issue is present in both. Subaru of America has rejected my replacement claims on both cars because the cutoff date for their open recall has expired. This is a major and constantly worsening safety issue that severely limits driver visibility. Because it developed slowly, it was not a safety concern until after closure of the recall.

2 Service Brakes problem

Failure Date: 10/25/2023

The contact owns a 2009 Subaru Legacy. The contact stated that while driving at an undisclosed speed, the brake pedal was depressed and went to the floorboard. The vehicle failed to stop immediately. The brake warning light was illuminated. The contact activated the parking brake to stop the vehicle. The contact was able to drive to the residence. Upon inspection, the contact noticed that the brake line was corroded and leaking brake fluid. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The contact stated that the vehicle was previously repaired at the dealer under NHTSA campaign number: 14v311000 (service brakes, hydraulic); however, the failure recurred. The failure mileage was approximately 56,000.

3 Service Brakes problem

Failure Date: 12/20/2022

Passenger rear brake line corroded and burst causing loss of brake fluid. Due to the loss of brake fluid, I lost 95% of brake pressure making it very difficult to stop. Only reason I say 95% is because the brake system is designed to still function in limp mode, but still terrifying while driving. The problem was discovered by myself as I was a certified technician for over 10 years for this brand. The vehicle hasn’t been looked at by anyone but myself. The brake lamp indicator did come on shortly before the line burst.

4 Service Brakes problem

Failure Date: 10/08/2021

Following traffic and under heavy braking due to lead vehicle braking hard and making turn without turn signal, brake pedal went to floor and vehicle continued traveling forward resulting in rear end collision with vehicle in front. Upon inspection at dealership both rear brake lines found to be corroded badly and sever leakage from both left and right rear brake lines. Corrosion & weeping also noted by dealership body shop on both lines coming out of vehicle from under rear seat above fuel tank. The corrosion and leakage matches with recall campaign 14v311000.

5 Service Brakes problem

Failure Date: 07/07/2021

While driving the brakelines were affected and brakes weren't working any longer. I see online there is a recall for my specific car. The recall is for corrosion of the brake lines in specific snow states and the use of salt. I live in CT and bought the car from a private owner. I looked to see if the car was ever serviced for the recall and I am finding nothing on it. Thr exact spot indicated in the recall is exactly where the brake lines corroded so much that there is a hole now. Thanks for your time.
