If the screws come loose, the pre-tensioner and retractor spring could separate from the belt entirely, which would be bad news in a crash. There's no mention of injuries or accidents due to the faulty pre-tensioners. Owners affected by the recall will be notified soon, and asked to come in for recall service.
Toyota Announces Voluntary Recall of Certain Tacoma Vehicles
TORRANCE, CA August 7, 2013 – Toyota Motor Sales, USA, Inc. today announced that it will conduct a voluntary safety recall involving approximately 342,000 Toyota Tacoma Access Cab vehicles, produced from 2004 to 2011.
In the involved vehicles, screws that attach the seat belt pre-tensioner to the seat belt retractor within the seat belt assembly for the driver and front passenger can become loose over time due to repeatedly and forcefully closing the access door. If the screws loosen completely, the seat belt pre-tensioner and the retractor spring cover could detach from the seat belt retractor, which can affect retractor and pre-tensioner performance.
Owners of vehicles subject to this recall will receive a notification by first class mail.
