Start by assembling a clear, itemized list of discrepancies with dated photos and a short summary of how the vehicle differs from the listing. Contact carvana support and request an on-site appraisal or return authorization, specifying whether you prefer repair, partial credit, or a full return. Ask for a single case handler, an ETA for remediation, and regular status updates until the matter is closed. Emphasize safety-impacting defects so the inspection is prioritized. Please request a single confirmation and an estimated timeframe so progress is visible and you can plan while support works the case.
