A South Jersey used-car dealer, SJMotorTrends, posted a TikTok describing a dispute with a customer who bought a Nissan in 2024, developed a transmission problem this year, and discovered her Carfax report had since been updated to show the transmission had already been replaced once - a detail that wasn't on the report she signed at purchase.
What actually changed
The original 2024 Carfax on file said the transmission was "checked" and something was "reprogrammed" - it never said "replaced." The newer report, for the same date and mileage, now adds "trans replaced." Carfax's response to the dealer's inquiry was described as generic, simply noting it receives millions of history records daily from thousands of sources.
Why this can happen - it's not necessarily shady
The FTC itself warns that vehicle history reports are only as current as the records feeding them, and that reports typically won't list mechanical problems and aren't a substitute for an independent inspection. A repair logged by a dealer or manufacturer weeks or months after a sale can surface on the report long after the paperwork was signed - so the report can genuinely be accurate-at-the-time and still change later as more data trickles in from different sources.
Complicating factor: mileage
The customer put 73,000 miles on the car in under two years. Nissan's standard powertrain warranty runs 60 months/60,000 miles, and even the extended 84-month/84,000-mile coverage from Nissan's CVT class-action settlements wouldn't fully help here - the mileage likely exceeds both windows regardless of the report issue.
Legal reality
The FTC's Used Car Rule requires an "As Is" Buyer's Guide be posted, which if marked as-is generally means the dealer owes nothing on a later failure. New Jersey's Used Car Lemon Law would have only covered this car for 30–90 days after the 2024 sale - so any legal warranty window is long closed, leaving this as a goodwill dispute rather than a legal obligation.
Where it landed
The dealer's manager offered $1,000 in parts at cost if she does the repair work with them, while acknowledging a full replacement runs far more than that. Nissan transmission jobs can run $8,000–$12,000, and per Kelley Blue Book cited in the piece, a fair-repair estimate runs north of $7,000.
This is a tough scenario, but we don’t hear it happen often so doing as much homework as you can goes without saying. Get that Car Inspection Score always.
Thanks for reading everybody!
