There are many recalls in the auto industry.
No matter how much you plan and hope that a project will be perfect, it rarely is. If a minor problem is detected, anyone can go with their car at the dealership and get it fixed for free. The 2007 Mini Cooper S was recalled on the base of a weird problem. While most cars get recalled for important or disturbing problems, the 2007 Mini Cooper S and even the 2008 version was recalled because of the length of the exhaust pipe, which sticks less than 1 inch out of the car. You can see a picture below.
The reason: people who pass the Mini when it is parked can get burned.
