The 2011 GMC Acadia features two motor mounts and is prone to various engine-related issues. Problems such as spark plug dislodgement, loose gaskets, oil leaks, and engine overheating can occur. If not addressed promptly, these issues could lead to more serious consequences like fires or vehicle explosions. Excessive oil consumption may necessitate more frequent oil changes than usual. It is recommended to change the coolant every 60,000 miles, replace the air filter every 15,000 to 30,000 miles, and swap out spark plugs every 100,000 miles for non-copper spark plugs, and every 30,000 miles for copper ones.
In the 2011 GMC Acadia, there are two engine mounts – one at the front and one at the rear. The front engine mount has a tendency to degrade more quickly because it is exposed to the heat from the catalytic converter.
