Cold Weather Causes Buick 'Clunk'

Jan. 18, 2023

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).
