The following Service Bulletin data is provided strictly for informational purposes only, to assist owners to find out if a particular problem they may be experiencing with their vehicles has been addressed with a factory service bulletin. If a listed problem or symptom is present or suspected, owners should consult their authorized Jeep service department for the latest up to date bulletins and proper procedures. Repairs, adjustments or modifications described in these TSB’s should be done by qualified service personnel only, especially when relating to safety and drivability issues. For a detailed explanation of TSB’s, see this article from Edmunds.com: You, Your Vehicle and the Technical Service Bulletin.
SERVICE BULLETINS ARE NOT A WARRANTY ITEM FOR VEHICLES OUT OF WARRANTY. It is important to note that “Preventive” service repairs will generally not be performed under warranty during the normal warranty period if a vehicle is not exhibiting the particular symptom or problem. TSB’s are not recalls. If you ask your dealer to perform the modification outside of the warranty period, expect to pay for the labor and parts.
