As part of an investigation, News Channel 5 has discovered possible inaccuracies in the way some car odometers measure mileage. Although the condition of your tires can apparently have an effect on whether your odometer records your miles accurately, the investigation revealed that lawyers are claiming that certain cars regularly overstate mileage by 4%. This has some consumers mad, and they have already brought suits against 2 big automakers. Some of their claims relate to consumers having to pay for extra miles over their limits when they turn in their cars. According to the article, the National Highway Traffic Safety Administration does not regulate the accuracy of odometers.
