Service bulletin 12-146-13

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

THIS BULLETIN PROVIDES INFORMATION REGARDING A CHANGE IN PRODUCTION TO THE DESIGN OF THE TRUNK TORSION SPRING MOUNTING BRACKET LOCATED ON THE UNDERSIDE OF THE REAR SHELF PANEL. THIS CHANGE WAS MADE TO REDUCE THE POSSIBILITY OF NOISE FROM THE TRUNK TORSION SPRINGS DURING OPENING AND / OR CLOSING OF THE TRUNK LID. THERE HAVE ALSO BEEN CHANGES MADE TO THE REPLACEMENT TRUNK TORSION SPRINGS. IT IS IMPORTANT TO IDENTIFY IF THE VEHICLE IS EQUIPPED WITH THE OLD-STYLE OR THE NEW-STYLE MOUNTING BRACKETS TO INSURE THE REPLACEMENT SPRINGS ARE PROPERLY POSITIONED AFTER INSTALLATION. COMPARISON ILLUSTRATIONS TO HELP IDENTIFY THESE CHANGES ARE SHOWN BELOW.
