Power train
34 reports1 crash
“My 2012 Subaru Legacy experiences involuntary engine stalling when coming to a quick stop, such as in stop-and-go traffic or during sudden braking at intersections. When the engine shuts off without warning, power steering and braking assist are lost, creating a serious risk of collision. This is a known issue documented by Subaru of America in Technical Service Bulletin 16-90-13R, applicable to 2010–2012 Legacy and Outback vehicles with CVT transmissions. Subaru attributes the condition to excessive thrust washer wear inside the torque converter, which prevents proper release of lock-up clutch pressure. Subaru describes the condition as similar to stopping a manual transmission vehicle without depressing the clutch, which inherently results in engine stalling. Subaru later redesigned the torque converter as a countermeasure beginning in October 2013, indicating prior knowledge of a defect. However, Subaru never issued a recall or notified owners and addressed the issue only through a non-customer-facing service bulletin. I contacted Subaru Customer Advocacy to report this safety concern and request assistance with the repair (quoted over $4,000). Subaru…”
Engine
23 reports
“Engine failed 3 cyclinders blew, car would not start, was able to drive car into parking lot (Einstein Bagels)before failure, otherwise could have been reared ended, as was in heavy traffic on westbound Dundee Road, in Palatine IL. Parking lot was near Dundee and Rand Road intersection”
Air bags
11 reports4 crashes9 related recalls
“Contacting Subaru going on 4 years to get airbag recall completed. Subaru has Persistently promised to call back to set appointment BUT NEVER CALLS. Just did 2 chats again today both MYSTERIOUSLY disconnected AS USUAL. Please record for legal purposes my absolute frustration at trying to get Subaru to fulfill this Critical RECALL for Deadly Airbag Repair”
Steering
7 reports1 crash
“WHEN BRAKING, THE CAR OFTEN STALLS AND ALL REQUIRES A SHIFT INTO PARK, AND A RESTART OF THE ENTIRE ENGINE BEFORE BEING ABLE TO PROCEED. WHEN IT STALLS, STEERING IS ALSO AFFECTED. THIS FREQUENTLY HAPPENS ON CITY STREETS, BUT ALSO HAPPENS WHEN PULLING INTO PARKING SPACES AND WHEN SLOWING FOR TURNING. THIS HAS BEEN HAPPENING WITH INCREASING FREQUENCY.”
Service brakes
6 reports1 crash
“The brake lines of my vehicle were corroded and started leaking brake fluid. The brakes no longer work and started failing when I was driving up a hill. Luckily there was no accident, however, not having functioning breaks is an obvious safety concern. An independent service center initially looked at the damage and suggested that the corrosion is unacceptable for the life of the vehicle. They provided me with the recall information I include below and instructed me to take the vehicle to a Subaru dealership. The dealership confirmed the issue and offered a quote of $5,000 for the repair. There is a recall for the same exact issue for similar vehicles (Subaru Recall Campaign WQK47: Brake Line Corrosion). The recall includes 2005‐2009 model year Subaru Legacy and Outback vehicles, 2008‐2014 model year Subaru Impreza WRX and STI vehicles, and others. However, it neglects to include 2012 model year Subaru Legacy vehicles. The issue is clearly the same.”
Suspension
4 reports1 crash
“Vehicle: 2012 Subaru Legacy VIN: [XXX] Owner Location: Syracuse, NY (salt-belt state) Dealer: Romano Subaru (Syracuse, NY) Dealer Findings / Estimate: “Urgent Work — Subframe with sway links — $3,119.89” (front subframe replacement required), plus alignment and related items; total estimate $4,394.75. Summary of Safety Defect: The front subframe has corrosion holes near structural/mounting points. This compromises suspension/steering integrity and presents a risk of sudden loss of control while driving. Manufacturer Response (Subaru of America): I opened a case with Subaru Corporate. Subaru denied assistance on the basis of vehicle age (2012) and absence of a front-subframe recall, and instead offered a $500 coupon toward a new vehicle. This response does not address the current safety defect documented by a Subaru dealer. Why NHTSA Action Is Warranted: •Subaru has already recalled the rear subframe on these models in salt-belt states (NHTSA 19V-297) due to corrosion-related failure. •My vehicle exhibits the same corrosion failure on the front subframe, a critical load-bearing structure. •A safety defect should be addressed regardless of vehicle age.
