We bought a 2018 Pacifica Limited which has a 3.6L V6 24V VVT Engine with ESS. It was purchased on 7/2/18 with 17 miles on it. Since then I have had battery drain down problems 4 times. Twice the battery could not be jump started by Chrysler Roadside Assistance (CRA) and had to replaced. The car is with the dealer today and I am hoping they would find the problem. My 3rd minivan and 2 cars from Chrysler/Dodge. The problems were their transmission at 100K miles. Have owned minivans since 1990 (wife loves them).
Chrysler Pacifica was rated the best and I took another chance. Complains of battery life on Chrysler products have been reported on the newer vehicles, but nothing specific. Ther was one that identified Uconnect system draining the battery by turning the radio on (not sure how this happens).
Any ideas of the root cause of battery drain down would be appreciated.
The only thing that I can think of is that your Pacifica may have been on the dealers lot for quite some time,
and the battery became discharged to the point that it won't reach a full charge.
Keep us posted on your resolution.
A friend had this problem. They either replaced the radio or re-flashed it and it fixed the problem.
240ZMan there was a TSB 08-056-18 REV. A released on November 3rd that MAY address your battery drainage concern. If your vehicle is currently at the dealer please have them apply this TSB 08-056-18 REV. A
Please let me know if your need any additional assistance
