What problems does the GMC Acadia exhaust system have?
Years 2007-2016

Answer

Many of these exhaust problems on GMC Acadia are reported on forums, where in some instances the exhaust fumes would even enter the vehicle, causing discomfort in the occupants of the vehicle. In others, important contaminants have been detected in the fumes. Let's see what the symptoms are. When the exhaust leak comes out, it is accompanied by a loud and booming sound: it is the sound of the unmuffled exhaust, and it is the most obvious symptom. It also has a terrible smell, and as we have seen it can return to the passenger compartment, forcing the windows to be opened immediately, regardless of the outside temperature. Simultaneously with all this, a warning light on the dashboard should turn on, a strong vibration of the accelerator pedal and at this point the car begins to consume a lot. Extended driving in these conditions will inevitably damage the catalytic converter. Also remember that if the exhaust smells, carbon monoxide has no smell and can be very, very dangerous for anyone inside the car. The causes can be apparently trivial, such as a gasket that has blown between the exhaust manifold and the cylinder head. This is the most common cause of this disaster. But the bolts that connect them can also be the cause, maybe just because the tightening has come loose! On the other side of the exhaust manifold is the gasket that connects it to the exhaust system. This could also be a culprit. Rare but possible, the exhaust manifold may have cracked; or that the exhaust system is so rusty that it leaks there. They are all possible defendants.
