The National Highway Traffic Safety Administration has announced that it is expanding the investigation into used Mini Coopers, revealing that problems with the cars' power steering may extend to some 60,000 vehicles.

Mini Coopers from 2004 and 2005 are expected to be included in the probe, which was first launched in September of 2010. The organization was spurred to action after receiving more than 300 complaints about the loss of power steering on the cars, making them extremely difficult to control. BMW says it has received less than 200 complaints, although there have been 4,500 claims for power steering related issues on warranties.

According to the automaker, five accidents and three fires have been attributed to issues with the power steering, fortunately resulting in no serious injuries. The complaints aren't completely consistent – some say that the issue is permanent, while others say the loss is only temporary.

The models in question are currently undergoing engineering analysis by the NHTSA, which will determine if a full recall is necessary.

Drivers interested in purchasing a used vehicle should check the latest safety news to ensure that the model they are considering isn't involved in any serious recalls. Once they've decided on a car, New Jersey State Auto Auction can offer affordable prices and finance options.
