We have a 2018 Pacifica Limited (Gasoline) that is one year old tomorrow. My wife does not drive it as much as I would like so it has less than 5000 miles on it. When I drive it, I run up through the driver information screens. One is for auto stop / start. I drove it all day today and it said auto stop / start not available battery charging. We don't like the auto feature and will often turn it off but since I did not see that notice go away, it is apparent to me that one of three things is happening. Either the second (auto stop / start) battery is defective and cannot hold a charge, the charger for that battery is not working right or the sensor that gives that message is defective. The vehicle did not try to stop at lights today but here in hot Florida, that is okay. Had that feature been working, it would have stopped at least part of the time. Should I be worried we have other electrical problems including starting issues for the main battery? Do any of you have same issues and what did you (or the dealer) do about it? I assume it is warranty for low mile one year old vehicle but from other posts, it appears those batteries are not readily available. Thanks in advance for any advice you experts can offer us.
