Nissan is conducting a Voluntary Service Campaign on certain Model Year 2011 Nissan Quest vehicles equipped with a genuine Nissan accessory tow hitch. These accessory tow hitches were manufactured without drain holes, which may result in corrosion. Certain vehicles, identified in Service COMM, are known to have tow hitches without drain holes and will have the tow hitch replaced at no charge for parts or labor. See this bulletin for further detail. Campaign ID # PC195
