I just bought this 2002 chevy Impala for my son for his graduation. The previous owners seem to take great care of this car and the only issue it had was the gas gauge was not accurate. It fluctuates between full and empty. This week it seems to be stuck on full, but every now and then come down to empty then right back to full . We have my son drive my younger boys back and forth to school and he drives long distances to go to his army trainings. It has become an issue for him to remember how much gas is in the tank. And has become a worry for me that he might get stranded somewhere due to no gas. After reviewing the complaints it sounds like we are not the only ones with this issue. Hope the manufacturer does something about this soon.
