Real SUBARU OUTBACK Owner Reports (Source: NHTSA Complaints Database)

"I was driving at 65mph on highway in a like new 2011 Subaru Outback with 146,000 miles when the transmission valve body crapped out. This caused a severe shutter and loss of power like a missed gear, but thankfully I was able to coast off the highway without using the gas or without crashing."

What To Do Next

  1. 1
    Check for recalls on YOUR VIN

    Go to nhtsa.gov/recalls and enter your VIN. Free repairs if your vehicle is covered.

  2. 2
    Get a proper diagnosis

    A code alone doesn't tell you the exact failed part. A diagnostic at a shop ($50-$150) pinpoints the root cause before you spend money on parts.

  3. 3
    Compare repair quotes

    Get 2-3 quotes. Dealer vs independent shop prices often differ 30-50% for the same repair.
