How to Change Car Mileage: Understanding Odometer Fraud

June 13, 2024

Understanding and Preventing Odometer Fraud

Odometer fraud is an increasing concern in the used car market, with a notable 26% rise in reported cases in Detroit since 2019. This alarming trend underscores the need for both buyers and sellers to be aware of how odometers can be manipulated and the potential financial implications thereof.

Ease of Access to Fraud Tools

The tools required for committing odometer fraud are surprisingly accessible. Online platforms, including eBay, offer these devices for just over $200, making it relatively simple for fraudsters to obtain and use them. A repair shop demonstration highlighted just how quickly mileage readings could be adjusted, emphasizing the need for vigilance among consumers.

Financial Impact of Odometer Fraud

Odometer fraud can dramatically affect a vehicle’s market value. For instance, a case involving a 2007 Chevy Silverado showed that falsifying the mileage could increase its value from $14,000 to $22,000. This not only results in substantial financial gains for the perpetrator but also significant losses for unsuspecting buyers who end up purchasing overpriced vehicles.

Implications for Buyers and the Market

The prevalence of odometer fraud has broad implications for the used car market. Buyers need to be especially vigilant, carefully reviewing vehicle history reports from trusted sources like Carfax to avoid being deceived. The practice not only unfairly inflates prices but also potentially masks existing wear and tear that could lead to costly maintenance down the line.

Thorough Vehicle History Checks

Always request a comprehensive history report when considering a used car purchase. These reports provide invaluable information on the vehicle’s past, including recorded mileage at different points in time, which can help identify discrepancies. Organizations like Carfax even offer specialized services to detect odometer tampering.

Professional Inspections

Before finalizing any purchase, have the vehicle inspected by a professional. Mechanics can assess the actual wear and tear on the car’s components, which often tell a more accurate story than the odometer reading alone. Signs of excessive wear on the pedals, seats, and steering wheel may indicate that the car has been driven more than reported.

Public Awareness Campaigns

Raising public awareness about the risks and signs of odometer fraud can protect buyers and discourage fraudulent behavior. Educational campaigns can teach consumers what to look for, such as inconsistencies in the vehicle’s documentation or unusually fresh cosmetic improvements that might be hiding higher mileage.

Understanding the ease with which odometer fraud can be committed, the substantial financial impacts, and how to effectively prevent it ensures that consumers can navigate the used car market more safely. By remaining vigilant and informed, buyers can protect themselves from falling victim to these deceptive practices.
