Dr., I agree that this appears to be premature failure, while I do not have an electric cart, my automotive batteries which are subjected to much higher heat ( but lower cycling) typically last 4-5 years.

Did you use distilled water to fill the batteries? Did you always keep the batteries charged? Did you notice a difference in the amount of water used between batteries or cell within batteries? Does the cart sit for extended periods with out being used? Do you use a trickle or battery minder type of charger if no using the cart for an extend period? Did you see any corrosion on the batteries?

These are the type of questions that the manufacturer and dealer are thinking about, and probably why they are reluctant to replace/credit batteries, too many things can go wrong by the end user.

I have seen reports that some of the new (2017) gas carts are very quite and fume free, and that is what I will be looking at when we get ready to replace our cart.

I know this does not help, but I am sorry for your problems.
