My sister has a 5 year old Jazz - 21,000 miles and bought only 15months ago. Fully serviced including only 3 months ago. She has been told she needs a new gear box - £6,000 - she only paid £8,000 for the car - no explanation - no offer of contacting Honda Uk - nothing - can anyone help - she is beside herself with worry and frustration at Honda Newton Croydons attitude and lack of concern.
