Service bulletin - Warranty Extension: 2007?13 MDX and 2010?12 ZDX Front Active Damper - 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.
