Some Buick Enclave owners report experiencing issues with the interior sunroof latch due to a cheap plastic clip that can easily break over time. This plastic clip is crucial for holding the latch in place, and its failure may lead to improper latching of the sunroof, resulting in operational difficulties, increased noise, and potential blockages in the water drainage system. To resolve this problem, some owners have found it necessary to replace the front sunroof sunshade catch with the appropriate part number, such as P/N 84691055, rather than replacing the entire sunroof housing. Additionally, some individuals have successfully sourced durable replacement parts from platforms like eBay, which effectively secure the latch in place. It is advisable for owners experiencing this issue to consider these solutions to ensure the proper functionality and longevity of their sunroof latch.
