2 month old E-tron Sportback suddenly had drive malfunction and quattro malfunction warning lights. Car was not responding to accelerator pedal and would hop as if motor was engaging and disengaging repeatedly. Managed to get it to dealership. Turns out the rear drive control module needs replaced, which needs to come from Germany. Am researching lemon laws........ This is my 3rd electric car - E-Golf, Tesla 3, now Audi. So disappointed.
