The parking brake in question gets stuck because of a fractured internal gear.
In a move the California company describes as "overly cautious", an email has been sent to the owners of affected cars. The brakes contain a small gear that, if fractured, could prevent the brake from releasing, and thus the vehicle from being able to move.
Tesla said it hasn't seen "a single accident or injury" relating to the brake issue, and there have been no reports of the system failing to hold a parked vehicle or stop a vehicle in an emergency.
According to Tesla, the vehicles were manufactured between February and October 2016 and involves a gear in electric parking brakes that may not been manufactured properly.
"While less than 5 percent of the vehicles being recalled may be affected by this issue, we are recalling 53,000 vehicles total out of an abundance of caution", Tesla said.
The company said overnight that it was working with Italian supplier Freni Brembo to get the replacement parts. This has no bearing on the vehicles' regular brakes, and Tesla has received no reports of the parking brake system failing to hold a auto in place.
Tesla Inc. was sued by vehicle owners over claims its Autopilot feature is "dangerously defective" when engaged. We will soon be sending you an official recall notice by mail, which will include information on how to have your parking brakes replaced. Eager to please and attentive to the good of its customers.
