The United States office that handles highway safety announced it would investigate complaints that brakes can malfunction on Nissan’s popular Murano SUV.

According to documents released Friday by the National Highway Traffic Safety Administration, nearly 60 people have complained that the brakes on their cars lose pressure when trying to stop on a low-friction surface.

Some drivers reported increased stopping distances after pushing the pedal all the way to the floor. The investigation will cover upwards of 100,000 Muranos from the 2009 model year.

In a statement, Nissan said it is cooperating with the probe and encouraged any drivers experiencing brake problems to visit their local Nissan dealership.

Some drivers cited in the complaint said they replaced the anti-lock brake hydraulic control unit in their SUVs and that apparently fixed the problem.

The investigation will determine if Nissan needs to issue a recall on the vehicles. The NHTSA said the problem generally involves older, higher mileage vehicles.
