Hi John,
Thanks for the many informative replies you have posted. It certainly seems to have created a lot of comment. We’ve had our Sept 2015 SE for just over a year now and still pleased with it. As my original post outlined, the stop/start didn’t work for months in the winter, then settled down to being predictable during the summer months but has now reverted to its original old self. Not bothered now after reading these posts and as the car is approaching 4 1/2 years old, if it needed a battery then even at this ridiculous price it’s no big deal. One observation though is that there have been occasions when air con, lights, heater, radio have all been on after the car had been standing a few days (in summer) and the stop start worked, once after only 6 miles when I stopped to drop off a parcel at the post office. GRRR!
