When the check engine light comes on steadily, it's usually a generic warning. However, if it starts flashing, it's often a sign of engine misfires in your 2009 GMC Acadia. There could be various reasons behind this issue, but the bottom line is the same: don't keep driving your car until it's repaired. Driving with misfires can not only feel rough and bumpy but can also lead to lasting engine damage. While it's somewhat okay to drive your Acadia back home if the issue arises while you're out, you should have it checked promptly and avoid driving it until fixed. Repair costs may vary, ranging from inexpensive solutions to more costly ones, depending on the root cause.
