General Motors (GM) has recently issued a recall for a range of their vehicles, with a particular focus on the 2023 GMC Acadia models. This recall is due to the discovery of incorrectly installed transmission sun gears in these vehicles, a critical component for the smooth operation of the transmission system. This manufacturing error can cause severe transmission problems.

In the event that the half-shaft on the driver’s side of a vehicle were to become disengaged, the vehicle could experience a sudden loss of propulsion power.

This means that while in motion, the vehicle could unexpectedly lose its ability to move forward or backward, leaving it stranded in its current position. This could be particularly dangerous if it occurs while the vehicle is in traffic or at high speeds, as it could lead to collisions with other vehicles or obstacles.

The manufacturer previously released a GMC Acadia torque converter recall in 2020 due to missing bolts in the start stop accumulator endcap which could lead to a transmission oil leak. However, the 2020 recall primarily affects 2019-2020 GMC Acadia models, and is unrelated to the most recent recall.

    Signs your GMC Acadia has a bad transmission

    Signs that your vehicle has Acadia transmission issues can include, but are not limited to, unusual noises during gear shifts, or difficulty in changing gears. You might also notice a delay in vehicle movement despite pressing the accelerator, or the vehicle might jerk or shake while driving.

    A warning light on your dashboard, specifically the “check engine” light, can also be a sign of transmission problems. While this light can indicate a variety of issues, if it is accompanied by any of the other symptoms mentioned, it is likely related to the transmission.

    You may also notice a delay in vehicle movement despite pressing the accelerator. This is often described as the vehicle feeling sluggish or unresponsive. Lastly, if your vehicle starts to jerk or shake while driving, particularly at higher speeds, this could be a sign of a transmission problem.

    Does GMC fix the problem for free?

    Yes, as part of the recall fix, certified GM technicians will conduct a thorough inspection of your vehicle’s transmission system. If they identify any issues with the sun gear–a critical component of the transmission system–they will replace it as necessary.

    This service will be provided free of charge to ensure your vehicle remains safe and performs optimally. We always advise scheduling an appointment with your dealership at the earliest sign of trouble to prevent an accident.

    What should I do if my Acadia’s transmission is causing problems?

    The first step is to identify the problem. If you notice any unusual noises, difficulty in shifting gears, or a warning light on your dashboard, these could be signs of a transmission issue.

    As part of the 2020 transmission recall, dealerships will perform a thorough inspection of the start-stop transmission accumulator in your vehicle. If they discover any missing bolts, they will replace the entire unit free of charge. This measure is designed to prevent potential transmission oil leaks and loss of propulsion, which could increase the risk of an accident.

    As part of the 2023 transmission recall, dealerships will inspect the transmission to determine whether the sun gear requires replacement. If so, the component will be replaced at no cost to consumers.
