I have a B-Max 1 litre 120 purchased in December 2012. The stop/start system stopped working this month and I took it to the dealer who said the battery was only 75% charged hence the stop/start not working. This system doesn't work unless the battery is fully charged. What they do not tell you however, is also that if you do low mileage the system will switch itself off completely. If you have your aircon on the system will also not work. Could this be due to a low capacity battery or some other fault. I cannot be the only one having this problem - is there anyone else out there? I have been in contact with Ford who sent me to another dealer for a second opinion - they are now trying to contact my dealer without any success at present.
