Summary
Service Update - On certain 2020 model year GMC Acadia vehicles, equipped with a 2.5L engine (RPO LCV), the dash panel silencer attachment stud may lack sufficient clearance to the intake manifold resonator. When the engine is under load, the stud could make contact with the resonator. Dealers will cut off 6mm of the center stud.
