General Motors’ Noise, Vibration and Harshness (NVH) engineers have determined that removing the driver-side lower hush panel from the Acadia, XT5 and XT6 does not degrade the interior noise level of these crossovers and can thus be removed without negative consequence. The driver-side lower hush panel is normally used to cut down noise coming in from under the vehicle and from the engine compartment. Removing this unnecessary panel will likely save the automaker a small amount of money on parts at the assembly plant.
This change will be applied to 2021 GMC Acadia, Cadillac XT5 and Cadillac XT5 crossovers built from here on out, along with all 2022 model year versions of these three nameplates. All three of these vehicles are produced at the GM Spring Hill Assembly plant in Tennessee. Going forward, the GM Spring Hill plant will also produce the 2023 Cadillac Lyriq electric crossover, which will enter production there early next year.
Vehicle production at the GM Spring Hill plant was put on pause on August 23rd and was expected to resume on September 6th, however the shutdown has now been extended until later in the month. The Spring Hill plant has experienced recurring shutdowns amid the global semiconductor chip shortage, having previously been shut down from July 19th through to August 9th. The 7.9-million-square-foot facility sits on 2,000 acres of land located just south of Nashville and employs 2,764 hourly workers and 411 salaried workers for a total workforce size of 3,175. Employees at Spring Hill are represented by UAW Local 1853.
