Summary
Infiniti
is conducting a voluntary safety recall campaign on certain model year 1997 - 2003 QX4 vehicles that are currently registered in Salt States to inspect for corrosion, and if necessary repair the front strut housing panels. In addition to the recall campaign, in the interest of customer satisfaction, owners of similar vehicles that are not subject to the recall because they were originally sold in and are registered in States where corrosion is unlikely to occur will receive a courtesy notification and will be offered an opportunity to have their vehicles inspected at no charge. If necessary, the vehicles will also be remedied free of charge. See this bulletin for further detail. Campaign ID#: R1110 NHTSA #: 11V-244

Patching Perforated Areas
(Level 2 repair, driver side AND passenger side – continued)
NOTE: The Photo in Figure RB29 is an example of possible perforation. The vehicle you are working on
may have perforation in additional areas, areas different than these, or may not have any perforation.
If the vehicle you are working on does not have perforation, skip to step 36.
33. Cut fiberglass cloth to cover perforated areas (see example in Figure RB29).
•
Cut cloth to cover at least 1 inch beyond the perforation on all sides, except when the perforation is
next to the repair bracket.
•
Where perforation is next to the repair bracket, cut cloth to fit along the edge of the repair bracket.
•
If there is more then one perforation, cut fiberglass cloth for each perforated area.
•
Use 3M™ Bondo Fiberglass Repair Kit (P/N 422) or equivalent.
•
Use protective gloves (such as rubber gloves or disposable gloves) while working with fiberglass and
resin.
•
Do not install fiberglass patch on or over the repair bracket.
