My son's partner bought a car on Friday the 27th November 2015 from New Breed Motors Bunbury. We picked it up and we were driving when it cut out twice on the way home, leaving her upset and scared as she is only on L plates, not to mention how dangerous it was. My husband accessed under the bonnet and thought it might just be a loose battery terminal. I rang [name related - Community Guidelines] on his mobile and told him what had happened and that husband would tighten the battery terminal. My son drove her to work on Sunday the 29th 2015 and the new car cut out twice on the way there and on the way back. I again rang [name related - Community Guidelines] New Breed Motors and he said, "just drop it in". I said, "that's too difficult", so they picked it up just after 12.30 pm on Monday the 1st December 2015 and it also cut out twice on him getting it to the car yard. This car was purchased for $8000 on the Friday the 27th of November and broke down on the way home. What are our legal rights under Australian Consumer Law?
