In December 30, 2024, we bought a used 2020 Chrysler Pacifica with 22,500 miles ( out of warranty) and last few weeks I noticed that car. one time had difficulties to start ( nothing major but I felt it) . Then this week on Thursday morning after vehicle sat inside the garage for three days, ligh…

I have the same car. You can disable the nuisance auto/start/stop from the console, but you have to do it every time you turn on the engine. Not sure how the aux battery fits into the picture if the system is disabled.

Original cheap undersized battery is dying. It seems premature. You must have bought that car last December 30 2023 (I assume you already have it). It’s at least three years old, maybe four depending on build date, and you have no idea what the previous owner did to the car. They may have run the ba…

[image] dhallis: Have a real garage check the car over, but I’d expect that the real problem is that junk battery Stellantis installed. The OP has posted that they have a new battery and it has solved their problem.

Is an auxiliary battery like this becoming a common thing? I’ve never heard of it before. dhallis (above) might be referring to the original main battery. It has not been replaced. This might be, or could be, discussed at allpar.com , a site that specializes in Chrysler and its related brands of veh…

[image] shanonia: Is an auxiliary battery like this becoming a common thing? I’ve never heard of it before. It is for the Start/Stop function, it has been mentioned in several post here… It is not just a Mopar thing… https://www.carbase.co.uk/news-and-features/used-car-buying-guide/a-guide-t…

Thanks, but that carbase.co.uk article doesn’t go into detail about the technology behind the start-stop function - no mention of an auxiliary battery, for example. A Chevy Cruze I rented in Texas a few years ago had the feature. It worked smoothly and seamlessly. I never looked under the hood, and…

[image] shanonia: This Chrysler van with aux battery is the first I’ve heard of starting problems with the feature. I put some battery’s (both battery’s) in Jeeps with the start/stop function back in 2018, and the vehicles were already out of warranty, so it has been around a while… [imag…

It seems that start stop has been around for a very long time, imo it is nothing more than a stepping stone to hybrids/EVs, at 1st for the vehicles, now more for the drivers to get used to, at minimum, hybrids to full on EV vehicles, just like the computer controlled carburetor was to fuel injection…

[image] shanonia: Is an auxiliary battery like this becoming a common thing? I’ve never heard of it before. This is also the first I’m hearing of this “small battery to power the automatic start-stop function”. Surprising, b/c with a two-battery configuration, it seems like you’d want to use …

One advantage of a hybrid - it has a huge battery and electric motor handling the stop/start feature, it’s seamless.
