Thanks.
Pretty much what y'all have acknowledged. It's still going on. But, it's reassuring to get some confirmation, and to know we are not alone.
I played golf two days ago and the cart I unplugged first was totally dead. Then, the one I took died on the 10th hole.
First year, solenoid failure/autobrake lockup. All solenoids were replaced. A few of them have failed.
Now, batteries/charge quality is the big problem. Some regularly die during the first 18. Some won't accept a charge, just keep flipping chargers to flashing red.
Some battery terminals and cable connectors are heavily corroded and "dissolved".
The original battery autofill system that came with the carts was not reliable. A few cells were not getting filled. But, I can't blame the problems on that.
Dealer promised to put in the new software to extend range/limp mode point, but hasn't yet. Generally speaking, response has been reluctant to acknowledge problems in general with early RXVs and slow to respond. It took a couple of big months of autobrake failures in the 2009 season to get them replaced, and no response at all concerning the battery issue we are now having.
We are at 2 1/2 years with them, and will never make 5.
I have had use the Internet to discover problems and solutions. I worked with a fleet of Club Cars before this and that fleet never had these problems.
