Tommy and Cristi Hill of Brighton said they left the Chevy at home while they went out to eat and shop Saturday and returned to find the bees swarming under the hood and over the windshield of the vehicle, The (Memphis) Commercial Appeal reported Tuesday.
The Hills said they do not want to kill the bees, so they tried strategies including driving the vehicle 60 to 65 mph down U.S. 51 and taking the Chevy through a car wash.
The couple said the bees returned each time.
Local beekeeper Bill Hughes said he tried to lure the bees into hives loaded in the back of his pickup truck, but "they've decided that car is their home."
Hughes estimated there are 25,000 bees swarming the car and a queen bee can lay up to 2,000 eggs per day.
The beekeeper told the couple to scare the bees off with a garden hose after dark and then park the car at least half a mile away.
"There's no telling what they'll do," Hughes said. He said the insects may just wait in a nearby tree for the Chevy to return.
