Bought my car in 2018 with a "clean Carfax". AFTER buying my car, Carfax added structural damage PREDATING the sale. Other car searches show no damage, I've had it inspected and no damage has been detected, but Carfax won't fix the report. They stated I need it from the seller but won't disclose who the seller is and by their own admission in writing in email, they have too many cars to process data efficiently and their own reporting will be incomplete.
