Estimated percentage containing defect: 7%
Description of defect:
A silencer pad can sag and contact the exhaust gas recirculation (EGR) cooler, which can result
in an engine compartment fire.
The following chronology of principal events led to the determination of a defect:
•
In October of 2007 an internal investigation was initiated based on two reports of engine compartment silencer pads burned away in the area of the EGR cooler. Both were heavy duty pick ups equipped with 6.7L diesel engines, introduced during the 2007 model year.
•
As a precautionary measure, in November of 2007 aluminum scrim and additional silencer pad fasteners were added adjacent to the EGR cooler while the investigation continued.
•
Thermal studies determined the EGR cooler may achieve temperatures in excess of 900 F under certain driving conditions.
•
A survey was initiated to evaluate silencer pad clearance to EGR cooler. Although the vast majority of vehicles exhibited significant clearance, 2 of 29 silencer pads exhibited contact with the EGR cooler (7%).
•
Ongoing evaluation of high mileage vehicles determined engine compartment moisture may contribute to silencer pad sagging in the area of the EGR cooler.
•
Monitoring of vehicles built post-November of 2007 has verified elimination of the sag potential with addition of the aluminum scrim and additional fasteners.
•
Chrysler is currently aware of 14 complaints of engine compartment fire with vehicles built prior to November of 2007 that may be related to this issue.
•
This data was presented to the Vehicle Regulations Committee on November 25,2008 who decided to conduct a safety recall.
Statement of measures to be taken to correct defect:
Chrysler will conduct a safety recall to add a bracket to support the engine compartment silencer pad adjacent to the EGR cooler. Chrysler expects to initiate national notification to both dealers and owners in December of 2008.
Chrysler has a longstanding poiicy and practice of reimbursing owners who have incurred the cost of repairing a problem that subsequently becomes the subject of a field action. To ensure consistency, Chrysler, as part of the owner letter, will request that customers send original receipt and/or other adequate proof of payment to the company for confirmation of the expense.
