What “clocking” means
Clocking refers to rolling back or freezing the odometer so fewer miles are displayed. The practice has been reported nationwide. Premium‑brand models and popular family SUVs are frequently targeted due to resale values.
Where available, compare module records with paperwork. If inconsistencies are present, request written disclosure from the seller before payment.
