MINI Model year 2004 Vehicles – Extended Rust Perforation Warranty

The MINI division of BMW of North America, LLC is pleased to inform you that all 2004 model year vehicles will receive upgraded coverage under the Rust Perforation Limited Warranty. The coverage has increased from 6 years to 12 years without mileage limitation commencing on the date of first retail sale or the date the vehicle is first placed in service as a demonstrator or company vehicle, whichever is earlier.

Please note that this increased coverage supercedes all references throughout this booklet to the lesser 6 year coverage.

This is really an interesting development. First off why is this only for '04 models? What happened to that batch of production that would lead MINI to believe there might be some issues with rust after 6 years. Or is there something else at work here? Lots of questions here and so far not many answers. Hopefully we'll have some soon.
