NHTSA Complaint #11476541 — 2011 SUBARU OUTBACK

The 2011 Subaru Outback subframe (K-Frame) failed structurally while the vehicle was in operation. The bolted connection between the left side (driver side) control arm broke due to extensive corrosion of the K-frame allowing the bolt to pull through one side of the box-shaped frame. The vehicle exhibited a pronounced pull to the left and handled erratically. The vehicle was immediately driven to a local repair facility where the broken frame connections at the control arms was discovered. The vehicle has approximately 79,000 miles and has been regularly serviced. Evidence of heavy corrosion and metal fatigue were noted at several locations on the K-frame (photo attached). The 2011 Subaru Outback has been owned/operated in western NY State where roads are frequently treated with brime and salt throughout the winter season. Servicing mechanic noted that he had completed recent replacement of the K-Frame on an identical year, make, model Subaru within the previous 3 months. Comparison of the K-Frame removed from my vehicle with the identical model showed similar corrosion and failure points. The symptoms and causes of this structural failure are nearly identical to vehicle safety complaint filed by another 2011 Outback owner; NHTSA ID # 11474045. The failed subframe, along with a second subframe from an identical Subaru replaced earlier this summer are available for inspection at the motor vehicle repair facility. Photo attached. Insofar as this is the third reported structural failure on this model within a short span of a few months and Subaru has declined to address the matter responsibly, NHTSA intervention is warranted and necessary.
