We bought our 2019 Acadia with 4 miles on it. Just last weekend, the fuel gauge started keeping an inaccurate account of our fuel level including making the low fuel beeping to happen while driving. We pulled over, restarted the car, and we were back to half a tank. When I fueled up today, the gauge will not go all the way over to full and keeps sending the error messages/beeps. It only has 23,770 miles on it. We've never let it run out of fuel either. The dealership said there's not a recall on it so I wanted to let our problem by known!.
