“Average car” = what the same number of complaints would include at the rate across every model year we track. Owners report these themselves; NHTSA doesn't confirm the cause.
What owners complain about most. From owner complaints to the government.

It measures complaints, not crash safety. A complaint is an owner's report, not a confirmed defect. How it works
