General Motors has issued a recall that affects nearly 6,300 police cars in the United States, reports the Associated Press. The vehicles are at risk of power-steering failure due to “corrosion on a connector,” the AP says, citing the company.
GM did not immediately respond to Fortune’s request for comment.
The faulty models consist of Chevrolet Caprice Police Pursuit vehicles spanning the years 2014 to 2016. In the event that their power-steering breaks down, manual steering is still available to drivers; however, their likelihood of collision increases.

“[T]he problem happens because police cars often run 20 hours per day and heat can build up under the hood while idling,” the AP reports, per GM. “The problem was discovered after an Illinois police department complained to GM of power steering losses in its fleet.”
The auto manufacturer told the AP that it has not received reports of crashes or injuries related to the defect, and that car dealers will swap out the flawed gear unit.
Last month GM recalled half a million trucks and SUVs for a brake pedal issue. In Oct. the company recalled 1.4 million cars for their risk of catching fire.
