The 20-year-old drove her passengers, dressed in hoodies and balaclavas, around the capital on 8 August, stopping at various shops so they could collect stolen goods.
The jury was told that Ms Johnson set out early in the evening to drop off a phone charger to her friend, convicted crack dealer Emmanuel Okubote. Proscutors told the court that Mr Okubote got into the passenger seat while others climbed into the back of the car.
Ms Johnson told detectives that she was ordered to act as a chauffeur for the group and felt too frightened to disobey.
Both Ms Johnson and her 17-year-old co-defendant were found guilty at the Old Bailey of stealing electrical goods from a Comet store at Greenwhich Retail Park, but were cleared of stealing a television from a Currys shop in south-east London.
The jury is still deliberating on a third charge of handling stolen goods.
