BMW is recalling 91,800 Mini Coopers to fix a defect that may prevent the air bag on the front passenger side of the cars from deploying in a crash. The problem affects the 2005 to 2008 models of the Mini Cooper and Cooper S. BMW says the air bag may not work properly because of a error that might prevent the vehicles' mat detection system from sensing a passenger sitting in the front seat during a severe crash. BMW has announced that  2005 to 2008 models of the Mini Cooper and Cooper S will need to be recalled due to problems with the passenger detection system that could leave those in the car without an airbad . BMW told the National Highway Traffic Safety Administration that it has been notified of one minor injury linked to the defect. To repair the problem, BMW will replace the detection mats in the affected models for free. The recall of the mats, which are manufactured in Germany, will begin May 1. There are 59,270 Mini Cooper and Cooper S models made between 2005 and 2006 affected by the issue along with 32,530  convertibles made between 2005 and July 2008, according to Bloomberg. Only one person has been injured so far as a result of the passenger seat (right) defect. The problem is thought to affect ten per cent of the 2005 and 2006 regular and 2005 to 2008 convertible models being recalled . Vehicle owners can get further information at 1-888-327-4236 or http://www.safercar.gov. BMW estimates that ten per cent of the cars being recalled actually have the detection mat problem. According to Motortrend, the current recalls is not the first such major incident for Mini Coopers in recent years. More than  90,000 cars made from 2006 to 2011 were also recalled in 2012 because of circuit board problems that could start vehicle fires.
