I just signed up our 2012 Overland at TrueDelta. However, they don't have enough participants to include MY2012 yet.
Michael Karesh is a JG member who is doing a great service by tracking real-world vehicle repair records. It is thanks in large part to his relationship with JG that TrueDelta has been able to publish actual WK2 frequency-of-repair records for the 2011 model.
If you have or about to obtain a 2012 WK2, you can sign on without cost at Michael's site: www.truedelta.com
You'll not only be able to provide feedback, but also see how other WK2s are faring.
