Those in the market for a used BMW might want to beware, as one iteration of the company’s Z4 sports car could have a power steering issue.

Reuters reports that the National Highway Traffic Safety Administration will investigate 48,764 units of the Z4 that were sold between 2003 and 2005. The regulatory body has received 107 complaints of a loss of power steering in the vehicle.

Hydraulic power steering systems allow drivers to easily navigate a vehicle with minimal effort. However, should the system fail, steering wheels can lock up or bind, requiring the driver to exert undue pressure in order to maintain the car’s trajectory.

The specific problem with the Z4 also seems more likely at speeds over 45 miles per hour and heat over 75 degrees.

The complaints included one accident, and several losses of control with “near-miss incidents,” according to the news source.

Consumers looking for a used car may want to steer clear of the Z4 until the investigation is complete. However, there are plenty of deals to be found on other used BMW models that are unaffected by the issue.
