The Toyota Sequoia's most persistent issue — and the dealer's most common response — is 'cannot duplicate.' Here is what to do when that happens:
1. DOCUMENT BEFORE YOU GO. Before each dealer visit, write down: the exact date and time of the malfunction, your mileage at the event, road conditions, and what you observed. For screen freeze: note whether CarPlay was active. For phantom braking: note the speed, road type, and nearest overhead structure. This contemporaneous log is admissible evidence in a lemon-law case; a vague 'it just does that sometimes' is not.
2. REQUEST A WRITTEN REPAIR ORDER FOR EVERY VISIT — even if the dealer finds nothing. California Song-Beverly counts 'attempts to repair' regardless of whether a defect was reproduced. A repair order that says 'inspected per customer concern — no fault found' is still a repair attempt that counts toward the lemon-law threshold.
3. INSIST THE DEALER RECORD THE EXACT SYMPTOM. Vague entries like 'software update performed' do not link the visit to your specific complaint. Ask the service advisor to write: 'Customer reports backup camera does not display when in Reverse' or 'Customer reports vehicle rolls in Neutral without brakes applied.' That specificity matters.
4. ASK WHETHER THE APPLICABLE RECALL HAS BEEN COMPLETED. For the Sequoia, confirm that Recalls 23V468000, 24V125000, 24V640000, 25V657000, and (for 2024) 24V767000 have each been performed and documented in the repair order. An unperformed recall is a pending warranty obligation.
5. FOR PHANTOM AEB EVENTS: Take note of the GPS coordinates or cross streets where the false braking occurred. If the radar is misreading the same overpass repeatedly, a geo-located log can help a technician reproduce the condition. Request the technician check for stored ADAS DTCs even if no warning light is on — some radar faults log a freeze-frame DTC without illuminating the dash.
6. FOR SCREEN FREEZE: Note whether a reboot clears the condition or whether a full power cycle (engine off/on) is required. If the multimedia unit is replaced, get the old unit serial number from your repair order — that confirms hardware was actually swapped, not just a software update the dealer misclassified.
7. TRACK CUMULATIVE DAYS OUT OF SERVICE. If your Sequoia has been at a dealer for 30 or more cumulative days since delivery for warranty repairs, you may qualify for a Song-Beverly refund or replacement regardless of the number of repair attempts.
