Service bulletin - Warranty Extension: 2007?09 MDX and 2010 ZDX Front Active Damper - This bulletin will expire May 8, 2017.
In cold areas, the front active dampers may be susceptible to leaking. Since these dampers are mounted in an inverted
position, the leak is not visible on the exterior of the damper. If an excessive amount of damper oil has leaked, the
active dampers may make a clunk or a bang when driving on rough roads or over speed bumps.
