Service bulletin LI35.31-P-080609

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

Complaint Consistent popping sound from rear of vehicle. AND Rear subframe manufactured on or after November 2025. Cause Under determination. Remedy Verify the noise is emanating from the rear subframe mounts and matches the sound file attached. The dealer may choose to use NVH to verify which mount. Replace all rear subframe mounts according to WIS and the attached procedures with Loctite. NOTE: If the mounts are on backorder when the order is put in initially, please open a parts ticket to understand availability time. It is not recommended to order the entire subframe assembly. If the mounts are on backorder per the response ticket from parts, the vehicle may be released until the parts arrive. If the sound matches the attached file and the subframe mount is manufactured prior to November 2025, open a TIPS case to the Body/Chassis Entertainment team.
