GM has issued a service bulletin to fix the internal seam and underbody sealers in 2023 Cadillac XT5 models.
The problem: during adhesion testing in-plant, the internal seam and underbody sealer may have failed.
The hazards: if the internal seam and underbody sealer were to have failed, then the vehicle’s structure could be compromised.
The fix: certified GM technicians will be instructed to inspect the sealer and apply new sealer to the affected areas. Technicians should not order from GMCCA and need to use 3-M Bare Metal Seam Sealer (Part no. 8310). The repair process should take roughly four hours.
Affected components: internal seam and underbody sealer.
Number of affected vehicles: GM does not currently know the number of affected vehicles at this time.
Owners should: owners of affected vehicles will receive an owner notification letter in the mail with instructions on how to proceed. Affected owners can reach out to Cadillac directly using the contact information included below.
