Although it has only found one faulty car, Tesla Motors is voluntarily recalling almost all Model S cars it has made to check for a front seatbelt problem.

In an email cited by Forbes.com, Tesla told owners it ahe recently found a Model S in Europe with a front seat belt that was not properly connected to the outboard lap pretensioner. "This vehicle was not involved in a crash and there were no injuries. However, in the event of a crash, a seat belt in this condition would not provide full protection…This is the only customer vehicle we know of with this condition. Even though we have since inspected the seat belts in over 3,000 vehicles spanning the entire range of Model S production and found no issues, we have decided to conduct a voluntary recall as a proactive and precautionary measure to inspect all front Model S seat belts and make absolutely sure that they are properly connected. (We have no concerns regarding seat belts in the rear of Model S.)"

Tesla added in the email that Model S owners may be able to "detect" the problem by "pulling very firmly on the lap portion of your seat belt."
