An auto parts seller was skeptical about the purported mileage on a Toyota Sienna’s odometer. A quick search online confirmed his initial distrust. The owner of Auto Parts City Inc. (@autopartscityinc) uploaded a video showcasing his CarFax sleuthing in real time. His bad car radar went off after he took a ride in what he calls the “worst Toyota Sienna” that he’s ever been in. Toyota Sienna Uber That’s Worse For Wear The Facebook user’s video begins with him riding in the back of an Uber. He asks the driver, “How many miles on this Toyota Sienna?” The rideshare worker says the odometer is currently sitting at 120,000 miles. However, the TikToker’s response seems to indicate that he doesn’t believe the driver’s estimate. He vocalizes his suspicions after he’s dropped off. “I just got out of this Uber. ... And there’s no possible way that that Uber only had 120,000 miles on it,” he tells his viewers. “It was just the worst Toyota Sienna I’ve ever been in in my entire life. So, once this guy drives by, I’m gonna grab his license plate, and we’re gonna run a Carfax on this thing. ‘Cause there’s no way it only had 120,000 miles on it.” After he records the Uber’s license plate, he screen shares his Carfax lookup of the Sienna’s tag. Sure enough, the information overlay states that the ride’s odometer may have been adjusted. “And, just as I suspected, ‘Potential odometer rollback detected.’ I knew something was wrong with this car,” he says. “The wheel bearings were shot. The suspension was shot. The interior was shot. There’s no way a Toyota Sienna with 120,000 miles on the odometer could be this bad.” How Many Miles Did The Toyota Sienna Actually Have Per The Carfax? Further scrutiny into the car’s history indicates that the minivan’s total mileage was more than double the amount the Uber driver told the TikToker. “This thing went almost to 200,000 miles before somebody rolled the odometer back to a hundred. So, this car’s got close to 300K on it,” the parts seller says. “I’m sure the driver doesn’t even know that. Sorry to call you out, mister Uber driver.” How Common Are Odometer Rollbacks? According to blog posts published by both CarPro and CarFax, used car odometer rollbacks have increased significantly between 2024 and 2025. The former website writes that this is “a sharp acceleration” from 2023 to 2024, which only saw a 4% “year-over-year increase,” as opposed to the 14% uptick that 2025 saw. CarFax’s vice president of data acquisition attributed this hike to the prevalence of digital odometers in modern vehicles. “Tampering has unfortunately become more common due to the wider availability of inexpensive tools,” he said. However, he did state that there is a silver lining, and it’s one that the Auto Parts City business owner demonstrated in his TikTok. “At the same time, a car’s mileage is now recorded more often, which allows us to identify discrepancies and better protect consumers.” Odometer Rollbacks Can Cost You Money Furthermore, CarPro argues that vehicles that are found with odometer rollbacks lose around $3,300 of their resale value on average. Conversely, this is why some unscrupulous car sellers would want to tamper with a vehicle’s official odometer readings to begin with. And if they’re selling a car privately, presenting a vehicle with less wear and tear can help fetch a higher price or gain interest from more buyers. CarFax also writes that some states have a higher number of cars with potentially rolled-back odometers. California leads the pack with 532,200 vehicles with tampered mileage counts. Texas came in second place with 333,900 rolled-back cars, followed by Florida, New York, Illinois, Pennsylvania, Georgia, Virginia, Arizona, and North Carolina. However, some folks on this Reddit r/UsedCars thread argued that just because a CarFax report contains an odometer flag, it doesn’t necessarily indicate that those numbers have been fudged. One person said that the practice is “not very common [because] a lot of the ‘odometer fraud’ out there is human error … fat fingering the numbers when a car is [in] for service and marking it at 100,400 miles instead of 10,400 miles, for example.” The same person added that folks should check the mileage discrepancies on CarFax if the vehicle has a service history, and to see if it stacks up with the odometer reading on the vehicle itself. Another commenter stated that folks really shouldn’t worry about odometer rollbacks when purchasing from a car dealership. “If it was a private seller I would worry about it,” they told the car buyer. But someone else contested that dealerships probably have a lot more to gain from an odometer rollback than an average Joe trying to sell their car online. When it comes to online private car sales, there have been Facebook posts uploaded by car shoppers who’ve noticed rollbacks. For example, this August 2025 instance was shared on the platform in the Lexington Car Culture group. And in a separate Reddit post, someone shopping for a second-gen Honda CR-V said that they noticed odometer discrepancies on a car they were interested in purchasing on Facebook Marketplace.
