When you buy a vehicle, one of the influencing factors is how many miles are on the odometer. That simple number can give a good indication of several items including:
- An indication of upcoming maintenance and repairs
- How well the vehicle was looked after
- If warranty is still applicable on the car
- The life expectancy of the vehicle
- The value of the car
Rolling back an odometer is done with the intention to defraud a purchaser. It gives the appearance of a less-used vehicle with more life left in it and fewer repairs on the horizon than it actually true.
Before digital odometers were introduced a few decades ago, it was a real concern whether an odometer had been tampered with.Inside the odometer, there were small plastic gears that could be disassembled and re-positioned so the value on the odometer was significantly reduced. Other times, the speedometer cable could be disconnected and run in reverse on a power drill to count the miles backwards.
Auto manufacturers combated this problem by creating safeguards in the odometer. On some, if the numbers were tampered with, it would be nearly impossible to make the numbers line up straight again, making it clear the odometer was rolled back. On others, the speedometer cable was designed to count the miles up whether the cable was turned in the forward or reverse direction. And finally, odometers were almost completely changed to digital readouts, which were thought to be foolproof.
With advances in technology, access to information is astounding. The process to roll back the odometer on cars equipped with digital readouts is available with a simple Google search and the tools needed to complete it are readily available online or at an auto parts store.
Detecting odometer fraud on modern vehicles with a digital odometer is more difficult but a few simple checks can assist you in detecting a potential rollback.
Method 1 of 4: Analyze the vehicle usage
Step 1: Consider the year of the vehicle and the current mileage.
An average vehicle in North America accumulates approximately 12,000 miles per year.
If the mileage is substantially less than 12,000 miles per year, there may be cause for concern.
Step 2: Consider the seller’s habits.
If the vehicle appears to be a business vehicle with decals or signs yet the mileage is abnormally low, it may have had its odometer tampered with.
If the seller is elderly as opposed to a busy parent or businessperson, it may be understandable that the mileage is not as high as average.
Method 2 of 4: Check the vehicle’s condition
Not every vehicle that has a rough interior and low miles is a case of a rolled-back odometer. Sometimes it is simply a case of the interior being neglected, but combined with other issues may be cause for concern.
Step 1: Check for abnormal wear on the brake and gas pedals.
The brake pedal sees the most amount of force and wear almost all the time. If the mileage on the car is low - less than 60,000 miles, for example - and the brake pedal’s rubber pad is nearly worn through, it can indicate a potential issue.
If the previous drivers drove in stop-and-go traffic predominantly, pedal wear will not be a clear indication of tampering.
Step 2: Check the carpets and seats for excessive wear.
Vehicle mats and carpets are quite durable and take tens of thousands of miles before they display wear.
If there are “heel spots” on the driver’s side floor mat or carpet yet the odometer seems too low for such wear, consider the possibility that the odometer has been tampered with.
Step 3: Check the body of the vehicle.
- If there seems to be more paint fade or body damage than you’d come to expect from the year and mileage on the car yet the odometer is low, think about the possibility that the odometer has been rolled back.
Step 3: Check for an odometer replacement sticker.
If the odometer was faulty and replaced at some point in the vehicle’s history, it is legally required that the odometer reading be recorded on a decal that is displayed on the vehicle.
The decal may be installed on the driver’s door pillar, on the instrument cluster, in the glove box, or another visible spot.
A decal has to be used if the new odometer that was installed could not be set to the previous mileage on the faulty odometer.
Method 4 of 4: Have a mechanic inspect the car
It can be difficult to determine if the odometer has actually been rolled back or not. Sometimes your senses tell you that something doesn’t seem quite right but you can’t identify what exactly is setting that feeling off.
If you suspect the odometer has been rolled back or want to confirm that the condition of the car is in line with the odometer, request to have a mechanic perform a pre-purchase inspection, which YourMechanic would be happy to do for you.
If the seller refuses to allow a mechanic to look over the car, it is a telltale sign that there is something amiss about the transaction. Whether the odometer has been rolled back or there is some other shady business happening, you should be confident in your decision to walk away from the purchase.
