Deborah McCullough bought a new car from Bill Swad Chrysler-Plymouth, Inc. The car was protected by both a limited warranty and an extended warranty. McCullough immediately encountered problems with the automobile's brakes, transmission, and air-conditioning and discovered a number of cosmetic defects as well.

She returned the car to Swad for repairs, but Swad did not fix the brakes properly or perform any of the cosmetic work. Moreover, new problems appeared with respect to the car's steering mechanism. McCullough returned the car twice more for repairs, but on each occasion, old problems persisted and new ones emerged.

After the engine abruptly shut off on a short trip away from home and the brakes again failed on a more extensive excursion, McCullough presented Swad with a list of thirty-two of the car's defects and demanded their correction.

When Swad failed to remedy more than a few of the problems, McCullough wrote a letter to Swad calling for rescission of the purchase agreement and a refund of the purchase price and offering to return the car upon receiving from Swad instructions regarding where to return it. Swad did not respond to the letter, and McCullough brought an action against Swad.

She continued to operate the vehicle until the time of trial, some seventeen and one-half months (and twenty-three thousand miles) later. Can McCullough rescind the agreement?
