General Motors has provided a solution to the front end rattle or clunking sound that affects some 2020 to 2023 model-year Cadillac XT5 units.
According to a recent post on the GM Techlink service website, a “rattle or clunk sound may be heard at the front of the vehicle on some” 2020-2023 model-year Cadillac XT5 vehicles. This problem may be related to a loose strut or sway bar, GM says, however it may also be the result of “a loose, mispositioned or improperly torqued cradle brace.” The cradle brace is a flat bar that is bolted across the center of the engine cradle (labeled #1 in the diagram below).
GM service technicians will be able to determine if the rattle or clunk sound is coming from the cradle brace, as opposed to a loose suspension component, by removing the cradle brace and getting behind the vehicle for a short period, while driving over small bumps or executing turning maneuvers. If the sound is no longer heard, it’s likely it was due to a loose or misaligned cradle brace.
To fix this problem, service technicians will re-install the cradle brace and ensure the bolts are torqued to spec. GM also notes the fasteners used on the cradle brace at single-use torque-to-yield fasteners, so the technicians must use new fasteners when tightening the brace back down to ensure it does not come loose again in the future.
This problem may affect 2020 to 2023 model-year Cadillac XT5 crossovers, as well as other C1XX-platform GM crossovers from certain model years, such as the Chevy Traverse, Chevy Blazer and GMC Acadia.
