Reliability & ownership notes

  • For a 2004 Wrangler, inspect frame and body corrosion, steering/suspension wear, four-wheel-drive operation, modifications and service history; verify engine and transmission by VIN before ordering parts.
  • Check the VIN in NHTSA's recall lookup for unrepaired safety recalls.
