GMC Acadia engine overheating with hard shifting and A/C disabled on GMC Acadia

Some GMC Acadia owners report experiencing engine overheating, which can lead to serious issues such as a blown head gasket and smoke from under the hood. This overheating may be caused by insufficient coolant levels or a malfunctioning thermostat, making it essential for owners to regularly check coolant levels to prevent such problems. Additionally, some owners encounter hard shifting and transmission slipping, which may require a thorough inspection of the transmission system for leaks and proper functioning. It is common for the A/C to be disabled during overheating episodes to reduce engine load, providing temporary relief while addressing the root cause. To mitigate these risks, owners are advised to take immediate action if overheating occurs, perform regular maintenance on the cooling system, and seek professional inspection if issues persist.
