The National Highway Transportation Safety Administration (NHTSA) recently announced a recall for a small number of 2012 Audi A6 vehicles. The agency reports that approximately 317 vehicles need to be inspected for possible issues with the air bags. Seams in the head curtain air bags may not have been sewn properly, which can render them useless. In the event of an accident, they might not deploy.

Air bags work together with seat belts to keep drivers and passengers safe in the event of a crash, and the NHTSA reports that they can significantly reduce the chance of injury by distributing crash forces more evenly across a person's body. If they are malfunctioning, an extended warranty can be used to cover the cost of any work that is needed to bring them back up to code.

Making sure that all the components of a vehicle work properly can greatly reduce the risk of a crash, which is why it is important for drivers to get regular tune ups. Doing so can catch problems early, but repairs can be expensive. A car warranty will pay for repairs and maintenance of certain auto parts so drivers can save money and keep their vehicles running well.
