A metro Atlanta used car broker has surrendered to authorities following a consumer investigation that uncovered allegations of systematic odometer tampering, leading to misdemeanor charges and highlighting broader risks in private vehicle sales.
Dennis S. Lewis, who runs DD Auto Brokers, reportedly turned himself in at the Gwinnett County Jail on February 4, 2026, after an arrest warrant was issued. The case stems from a months-long probe by Atlanta News First’s “Better Call Harry” consumer segment, which first exposed discrepancies in car listings on platforms like Facebook Marketplace.
Complaints Surface Over Mismatched Mileage Readings
The investigation began with complaints from buyers who purchased vehicles advertised with significantly lower mileage than actual readings indicated. In one prominent example, Shadesia Johnson and her mother Latrice spotted a 2013 Honda Ridgeline listed at 153,000 miles for $6,400.
After completing the purchase from Lewis, they took the truck for a mechanic’s inspection due to a check engine light. The mechanic flagged major issues, including two faulty catalytic converters.
A Carfax report initially aligned with the advertised mileage, but an emissions test from Metro Atlanta revealed nearly 285,000 miles—almost double what was shown.
Confronted with the evidence, the Johnsons demanded and received a full refund from Lewis.
Lewis initially defended his practices in interviews, acknowledging that mileages on his listings were “sometimes not right,” often due to engine replacements or other repairs.
He insisted he verbally explained discrepancies to buyers and suggested dissatisfied customers simply post complaints online. However, Atlanta News First says affected parties reported no such disclosures.
Carfax Records Reveal Pattern Across Multiple Vehicles
Carfax records reviewed during the investigation showed similar patterns across multiple vehicles sold through DD Auto Brokers. A 2006 Lexus RX was advertised at 155,000 miles but documented at 232,000 miles, a difference of 77,000 miles.
The broadcaster’s reporting prompted Gwinnett County police to launch a formal criminal probe. Detective Torren Huff led the effort, collecting additional complaints and police reports from prior customers.
None of the bills of sale or transaction documents indicated any mileage discrepancies had been disclosed.
As part of the investigation, authorities gave Lewis two months to produce business records. Despite follow-up notices, including a final warning, he failed to comply or respond. This non-cooperation contributed to charges that included odometer fraud, false advertising, and failure to produce required records, all misdemeanors carrying potential fines.
Additional Victim Comes Forward After Spotting News Story
Another victim, John Gronman from Opelika, Alabama, drove two hours to Atlanta after spotting the same 2006 Lexus RX on Facebook Marketplace.
He purchased it for $3,100 based on the advertised lower mileage. Suspicion arose when his temporary tag neared expiration. Researching the dealership online, including via AI tools like ChatGPT, led him to the aired news story.
Gronman described feeling physically ill upon realizing the potential deception. He filed a police report with Gwinnett County, providing key evidence that helped secure the warrant.
After the warrant became active, Lewis initially ignored outreach attempts but ultimately turned himself in voluntarily for booking.
Gronman declined an offered refund from Lewis, choosing to retain the vehicle despite anticipated high repair costs. He stated his decision to press forward with charges was motivated by a desire to prevent similar incidents affecting other buyers.
Consumer Warnings Issued Ahead of Case Resolution
The segment concluded with broader warnings from Better Call Harry. Carfax estimates that nearly 2.5 million vehicles nationwide currently have tampered odometers. Viewers were urged to exercise caution on platforms like Facebook Marketplace, which does not require identification numbers (VINs) in listings.
Recommended safeguards include always pulling independent vehicle history reports, insisting on pre-purchase mechanic inspections, and cross-checking mileage against local emissions testing records in areas like Metro Atlanta that track such data.
The case underscores ongoing challenges in unregulated private and small-scale used car sales, where odometer rollback schemes can inflate perceived vehicle value and leave buyers facing unexpected repair bills or safety risks.
Lewis’s surrender marks a resolution to the immediate investigation, though the misdemeanor nature of the charges suggests penalties may focus on fines rather than extended incarceration.
