GMC Acadia low fuel light illuminated with gas gauge reading empty despite full tank on GMC Acadia

Some GMC Acadia owners report experiencing issues with the low fuel light illuminating while the gas gauge shows empty, despite having a full tank. This may be due to a malfunctioning sensor that provides inaccurate readings on the gas gauge. Additionally, some owners find that the fuel gauge can remain lit even when there is sufficient fuel in the tank. Problems may also arise from the fuel pump shutting off prematurely at the gas station, affecting gauge accuracy. To mitigate these issues, using high-grade fuel can help extend the life of the fuel sensor and reduce erroneous readings. Furthermore, some owners have had success by moving and cleaning the terminals at the fuel relay under the hood. If these measures do not resolve the problem, it is advisable to consult a certified technician for a thorough inspection and necessary repairs.
