Why doesn't the stop-start function work on my car?
The stop-start, function on my two year old Mercedes-Benz SL350 AMG seems to work on a completely random basis. Some days it becomes operative after a journey of a mile while on others it will refuse to work. Is this a fault?

Reads as if the battery has lost some of its capacity to hold a full charge and that's why the system appears to be erratic.

I have a new Honda CR-V, with 5000 miles on the clock. Is it normal for the stop-start not to work and the low battery sign to come on?
I have a new Fiat 500 with stop/start, but the system refuses to work. It has been back to the garage numerous times because the stop/start does not apply itself when it should, and when it does it does...
What stop start battery would you recommend for my Skoda Octavis vRS? Prices seem hugely variable, as do warranties. How do I choose?

Impressively refined with a smooth ride. Folding metal roof means it’s as quiet as a coupe. AMG versions are brutally fast.
