General Motors has released a Customer Satisfaction Program for certain units of the 2021 to 2023 GMC Acadia over an issue of a concerning noise coming from the rear of the vehicle.
Select 2021 to 2023 model-year Acadia examples may have a condition where some customers notice a humming, whining, or squealing type of noise coming from the rear of the vehicle while driving anywhere between 20 to 70 mph. Certified GM technicians are to insect affected vehicles, and perform a test drive in an effort to replicate the noise. If this is found to be the case, the techs are to replace the torque tube assembly, which should take a little less than four hours to complete.
There are a number of vehicles covered under this Customer Satisfaction Program, including:
- 2021 to 2023 GMC Acadia
- 2021 to 2024 Buick Enclave
- 2021 to 2024 Cadillac XT5
- 2021 to 2024 Cadillac XT6
- 2021 to 2024 Chevy Blazer
- 2021 to 2024 Chevy Traverse
It’s worth noting that the cause of this noise is likely a damaged bearing.
As a reminder, the GMC Acadia is offered with one of two powerplant choices, either the turbocharged 2.0L I4 LSY gasoline engine, rated at 228 horsepower and 258 pound-feet of torque, or the optional naturally aspirated 3.6L V6 LGX gasoline engine, rated at 310 horsepower and 271 pound-feet of torque. Output is directed through the GM nine-speed automatic transmission, while FWD is standard and AWD is optional.
In regard to the all-new 2024 Acadia, the three-row crossover sees the introduction of an all-new generation that includes increased interior room, a fresh drivetrain, new on-board technologies, a long list of standard safety features, and a new design.
