Shares of the US luxury electric car-maker were down nearly 1% at $302.77 in afternoon trading, following its biggest recall to date.
Tesla's total production for 2016 was 83 922 vehicles and included both Model S and Model X.
"The electric parking brakes installed on Model S and Model X vehicles built between February and October 2016 may contain a small gear that could have been manufactured improperly by our third-party supplier," Tesla said in a statement on its Web site.
The car-maker said there had been no accidents or injuries due to the issue.Tesla said less than 5% of the vehicles being recalled may be affected and it would take less than 45 minutes to replace the brakes.
The company said it would send an official recall notice to its customers.
Tesla, led by entrepreneur Elon Musk, said last year it would recall 2 700 Model X sport utility vehicles in the US due to a faulty locking hinge in third-row seats.
The company said yesterday it was working with Italian supplier Freni Brembo SpA to get the replacement parts.
Brembo did not immediately respond to a request for comment.
