FTC Used Car Rule & State Guardrails

1. Align FTC Buyers Guide disclosures with state Implied Warranty rules

Ensure every retail unit displays an accurate FTC Buyers Guide ("As Is" where permitted vs Limited Warranty with exact % parts/labor and covered systems), and remember that in strict implied-warranty states (e.g., MA, NY, NJ, CT, MN, CA Buy-Here-Pay-Here), statutory coverage applies regardless of "As Is" stamps.

💡 Field Tip: Documenting baseline vehicle condition on a signed Delivery Inspection Term is your strongest defense against false pre-existing defect claims.

Tab 4 · Post-Sale Crisis Triage

2. Launch the Post-Sale Crisis Triage Widget in Tab 4 when a buyer calls

Customer texts that a warning light came on or an outside shop quoted $6,000? Select the symptom or paste their message in Tab 4 to generate: (1) Covered vs Non-Covered / Neglect classification, (2) De-escalating SMS/WhatsApp response script, and (3) Authorized Shop Triage Order.

Right to Inspect & Cure

3. Direct the vehicle to your authorized service bay before outside teardown

Never approve blind third-party retail repair quotes over the phone. Use our professional script to arrange immediate inspection or tow-in to your dealership or accredited partner repair shop so you control parts tier and flat-rate labor.

Objective Forensic Triage

4. Use ECU Freeze-Frame & thermal evidence to document buyer neglect

If a customer kept driving for 25 miles with a flashing red overheating alarm, flood-hydrolocked an intake, or ignored low-oil warnings, instruct your tech to export OBD2 Freeze-Frame timestamps and photos to objectively document consequential operator neglect.

Lot Manager & Master Technician Pro Tips

Fast, empathetic first response cuts attorney demand letters and 1-star Google/DealerRater reviews by over 70%.

Have every buyer sign the Mechanical Shield & Delivery Condition Checklist (Tab 2 / Tab 8) verifying fluid levels, tire tread, A/C operation, and Glovebox QR activation at delivery.

Most blown head gaskets start as a $90 hose or thermostat leak ignored by the driver — our Glovebox QR Guide stops that cascade on Day 1.

Frequently Asked Questions

Can a customer have their own mechanic tear down the engine and force our dealership to pay retail?

Under standard dealership limited warranty terms and state cure provisions, the selling dealer has the right to inspect the vehicle and perform covered repairs through its designated facility unless the dealer refuses or fails to respond timely. Always respond promptly in writing inviting the vehicle in for inspection.

How do we reduce policy-adjustment ("goodwill") expenses on 60-to-90-day comebacks?
