About the Acadia
The GMC Acadia first made its debut in 2006. Since then, GMC have released only two generations to hit the markets. The second iteration made its debut in 2017.
The crossover SUV has also been sold in the Australian market as the Holden Acadia.
Most of the competition comes from other American relatively large crossover SUVs. Similar models include the Ford Explorer, Chevrolet Traverse, and even the Mazda CX-9. It also faces competition from its considerably bigger sibling the GMC Yukon.
Over the two generations to be sold, fault code P0442 is one of the most commonly reported fault codes. This code indicates that a leak has been detected in the EVAP system.
Most American cars have this near the top of the list of their common codes. This is because simply leaving the fuel cap fastened incorrectly can cause this code to be logged. Other causes typically come from faulty components in the EVAP system.
Some owners have also reported P0449 to be fairly common. This code indicates that there is a malfunction with the vent solenoid in the EVAP system. This can add to the previous code.
In most cases, if these two codes are logged at the same time, the fix will involve replacing a faulty EVAP vent solenoid.
Another issue that has been noted by owners is P0300, which indicates multiple random misfires from the engine. Not only is this a serious issue but it can be very hard to pinpoint the cause.
Owners should always look for additional fault codes that could indicate where the solution may lie. However, it is typical for the issue to lie upstream of the engine in the fuel or air intake systems. Some owners have found that the fuel pump is prone to failing and causing this issue.
