Toyota Motor Co. is recalling 22,228 Tacoma pickups because the parking brake may not work, the automaker and federal safety regulators said Tuesday.

Tacomas from the 2005 model year with automatic transmissions are involved in the recall.

Toyota spokesman John Hanson said the company recalled the vehicles after the National Highway Traffic Safety Administration (news - web sites) received eight complaints. No injuries have been reported due to the defect, Hanson said.

Toyota said the lock nut on the parking brake cable may not have been properly tightened and can loosen and come off. If that happens, the vehicle could roll if it's stopped on a slope and the transmission isn't in park.

Toyota will notify owners of the recall next month. Dealers will tighten the lock nut for free.
