What To Do Next

  1. 1
    Check for recalls on YOUR VIN

    Go to nhtsa.gov/recalls and enter your VIN. If your vehicle is covered, repairs are free.

  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.
