Jeep Grand Cherokee: Rattling noise from sunroof when driving
A customer of ours is complaining of a rattling noise from the sunroof when driving on their 2015 Jeep Grand Cherokee. We have experienced the rattling noise on road test and have tightened all accessible nuts and bolts on the sunroof panel, but have not found the cause of the fault. Have you any ideas where to start to fix this car?
The fault you describe has been reported by other Grand Cherokee owners and it is due to an unsatisfactory design of the sunroof assembly retaining bolts. Specific retaining bolts are available from Jeep parts department and are required to rectify this fault. Ensure the sunroof is fully closed before disconnecting the battery. Lower the headlining to gain access to the sunroof assembly retaining bolts. Remove and replace the sunroof assembly retaining bolts one at a time. Tighten the sunroof assembly retaining bolts to the correct torque setting of 9 Nm. Carry out road test to ensure the rattling noise has been resolved.
