NHTSA crash-test safety rating

Federal 5-Star Safety Rating from crash testing. This is a separate government program from the recall(s) above — a high star rating says nothing about whether a specific recall has been fixed, and a recall says nothing about crash-test performance.

  • 20205/5

    2 trims tested for 2020; overall ratings can differ by trim.
