If the jounce bumpers are the cause of the concern, the bumpers should be replaced with new updated bumpers that remain softer in colder temperatures (P/N 84076339).

Some 2009-2016 Buick Enclave vehicles may exhibit a clunk noise at the rear suspension on moderate to severe jounce in cold temperatures approaching 0 degrees Fahrenheit. This may be caused by the rear suspension jounce bumpers becoming hard in cold temperatures, resulting in a bottoming-out feeling. If the jounce bumpers are the cause of the concern, the bumpers should be replaced with new updated bumpers that remain softer in colder temperatures (P/N 84076339).
